Door Buzzer
Installation in
Crown Heights

Quick answer: door buzzer installation in Crown Heights runs $400 to $900 installed on our Brooklyn list for an audio buzzer with talk-back and a door release on a one- or two-family row house, $700 to $1,800 for a video door station answered on indoor monitors or phones, and from about $2,500 to past $10,000 for a divided row house, a prewar walk-up, an elevator building on Eastern Parkway or a storefront building whose apartments need their own street door. Each figure includes the door station, the stations or phone answering inside, the power supply, the strike or release, the cable and the labor. It is fixed in writing after a walkthrough, and anything that might add to it, such as an old cable pair that could fail its test or a door frame that needs reinforcing before a strike will hold, is named and priced before you order. Crown Heights is billed at the Brooklyn rate. Here the door, more than the electronics, usually moves the price. Send photos of the door and the old panel to (347) 934-8335 or on WhatsApp, and we answer with the range that fits, usually within two hours of your message during working hours.

• Reviewing your photos and pricing a new system is free. When an existing system is dead and needs a diagnosis first, that is the $250 service call booked online, and the $250 is applied toward the work.
• All work is done under New York State license #12000287431. We install low-voltage entry equipment and door hardware; if the door needs a new 120-volt outlet or circuit for its power supply, a licensed electrician does that piece, and you know about it before the job is priced.
• We work for whoever controls the door: the homeowner, the landlord, the co-op or condo board, or the managing agent. Tenants are welcome to call for a price to bring to their landlord, but the work itself is booked by the owner.

Need Repair in Crown Heights? A Lock That Keeps Failing, a Line of Apartments Gone Quiet, or a Stoop Bell Nobody Hears

Calls that start with "our buzzer is broken" in Crown Heights usually turn out to be one of four things. The first is a door that no longer latches, so the release works but the door never needed it because it was already standing open. The second is a strike that has been beaten loose or a frame that has split around it, which is what a door looks like after someone has kicked or pried it a few times. The third is a riser fault in an apartment building, where every apartment above a certain floor or on one line has gone silent while the rest still work. The fourth, in row houses, is old bell wire that was spliced and painted over during one renovation or another until nobody knows which pair goes to which floor.

Each of those has a different repair, and only some of them call for a new system. If your street door will not lock today, say so when you call (347) 934-8335. A diagnosis is the $250 service call booked online, and that $250 is applied to the repair or to a replacement if replacing turns out to be the better value. You get both prices and a plain recommendation. If a part has to be ordered, the door is left closing, latching and opening with a key before the technician leaves, never propped and never with a temporary lock that fails open.

Door Buzzer Installation for Crown Heights' Architecture

Six kinds of building make up nearly every door buzzer job in Crown Heights. They differ in who controls the door, how many households the panel calls, where the cable can travel, and what the rules allow on the front of the building, and each has a mistake we see repeated.

Landmarked single-family row houses: one panel, one doorway, nothing that fights the stone

A one-family house in the Crown Heights North district is the simplest buzzer job in the neighborhood technically and the one that needs the most care about appearance. The household usually wants to know who is at the parlor door from the kitchen on the garden floor, or from a bedroom on the third floor, without walking down. That means a door station at the entrance, an answering station or phone app on two or three floors, and, if the family wants to let visitors in without coming down, a release in the door.

The mistake to avoid here is treating the house's two doors as one. Many families use the garden-floor door under the stoop every day and the parlor door only for guests. If visitors will ring at the top of the stoop while the family is downstairs, the station there has to reach the kitchen; if deliveries come to the lower door, that door may need its own button. We ask how the house is actually used before deciding where anything goes, because the one-panel-per-door rule means a second door gets its own small panel, not a second set of buttons crowded onto the first.

Row houses divided into apartments: shared stoop, separate households, old wire

The most common Crown Heights call is a row house carved into apartments long ago, with one stoop door serving every household above it. Brownstoner's account of the Park Place district notes conversions like this were already happening by the 1950s, and in many houses each later owner added a bell, a button or a cheap intercom without removing the last one. By the time we arrive, there may be three generations of wire in the walls, a five-button plate where only two buttons work, and a strike that was wired backwards so it buzzes but does not release.

The fix starts with tracing. A technician tests every pair from the door to each floor, marks which ones are continuous and which are cut or shorted, and finds the route the original installer used, often a narrow chase beside the stair, a closet stack or the cellar ceiling to a pipe chase. Sound pairs can carry a modern two-wire system, which runs voice, video, power and release over one pair to each station; Aiphone, for one, describes its GT Series as offering "the advantage of using existing wire and infrastructure." Where the old wire has failed, new cable follows the same hidden path wherever possible.

Prewar walk-ups and courtyard buildings: two doors, mailboxes and a riser that has seen everything

The brick walk-ups south of the parkway and on the northern side streets follow a familiar plan: a street door, a vestibule with the mailboxes and the panel, an inner door and a stair. Some are courtyard buildings, where the street door opens into a court and the apartments are reached through several separate entrances around it. These buildings carry the most legal weight, because a class A multiple dwelling of eight or more apartments built or converted after 1968 must have a working intercom under the Multiple Dwelling Law, and any building's public-hall doors have to close and lock by themselves.

The riser in a prewar walk-up has usually been through several systems, each reusing the last one's cable. We test it pair by pair before quoting. Pairs that test sound are reused, which keeps the price toward the low end of the multi-unit range; pairs that fail, or that look weak for video, are listed in the written price as possible replacements, each with its cost, so the owner knows before ordering exactly what could change. In a courtyard building, every entrance around the court gets the same treatment, because a single weak entrance is where the propping starts.

Elevator buildings on the parkway: big lobbies, many hands and a managing agent

The six-story buildings that face Eastern Parkway, and the larger complexes on the neighborhood's edges, have lobbies used by hundreds of people a week: residents, home aides, delivery workers, contractors and visitors. Their entry doors are often heavy steel or bronze in a wide frame, and the panel has to handle a long directory. Ebbets Field Apartments, which Patch notes was the largest state-subsidized complex in the five boroughs when it opened, is the extreme case, but even a 60-apartment building on the parkway puts more wear on a strike in a month than a row house does in a year.

For these buildings the panel is usually a code or directory panel, with residents dialing or scrolling to an apartment, and the apartments answer on wall stations, phones or both. The closer, strike and hinges are chosen for traffic, the panel housing for abuse, and the power supply gets battery backup so a short outage does not leave a door that cannot be released.

Stores with apartments above: the shop's doors and the tenants' door stay separate

Brownstoner's history of Franklin Avenue at Park Place describes the avenue as that part of Crown Heights' main commercial street, lined with commercial and residential buildings put up between the late 1880s and the early 1930s, including the corner building at 642 Park Place with its round tower and plate-glass ground floor. Nostrand, Kingston and Utica Avenues have the same mix. In most of these buildings, the apartments upstairs are reached through a narrow street door beside the shop, sometimes a few feet from the store's own entrance, sometimes around the corner on a side street.

We always keep the apartments' entry system separate from the shop. The tenants get a small panel at their own door, a station in each apartment and a power supply in a part of the building the owner controls, not behind the shop's counter. The store, if it wants one, gets its own buzzer at its back or side door. When both share one system, shoppers ring tenants, tenants can release strangers into the store's back hall, and every time the shop's alarm company or gate repairer touches the wiring, the apartments' door is at risk.

New construction: networked systems and who holds the keys

The Atlantic Avenue Mixed-Use Plan allows about 4,600 apartments on 21 blocks that 6sqft notes had been zoned for low industrial buildings since the 1960s, and smaller new buildings have been going up on infill lots across Crown Heights for years. These buildings are usually delivered with a networked entry system: a camera panel at the lobby, residents answering on a phone app or an apartment monitor, and a management office running the directory from a web portal.

Networked systems are good when someone owns them, and that is where the problems start. The developer's installer leaves, the management company changes, and nobody has the admin login, the subscription renewal date or the list of which credentials open which doors. Before we work on one, we ask the owner to confirm who holds the administrator account, whether there is a subscription and what it costs, and whether the panel uses the building's internet or its own connection. If the building is still under construction, we ask for those three things to be decided before the panel goes on the wall.

Kicked Frames, Smashed Glass and Doors Opened for Strangers: The Three Ways a Crown Heights Entrance Usually Fails

The frame that gives way

At 501 Lefferts Avenue, tenants told Patch that the lock could be changed but "the frame, they can kick it," and that young people sometimes broke the locks to hang out in the lobby and halls. That is a door problem, not an intercom problem. An electric strike is only as strong as the wood or steel it is screwed into, and a strike set into a frame that has been split and patched will tear out with the first good kick no matter how good the strike is.

When we find a frame like that, the written price includes reinforcing it before any release goes in: a steel reinforcement plate or a new strike-side jamb section on a wood frame, a filled and re-welded strike pocket on a hollow metal frame, and a latch guard where the gap between door and frame has been used to pry. On a door that has been abused for years, we may also recommend a new door and frame outright, and say so plainly with the price both ways. A buzzer installed on a door that cannot hold is a bad use of an owner's money.

The glass that breaks

The thief at 529 Brooklyn Avenue did not touch the lock at all; according to CrownHeights.info, he broke the glass front door of the building with a heavy object and walked in. Many Crown Heights apartment buildings have doors that are mostly glass in a wood or aluminum frame, and the original row-house doors have glass panels too. A glass pane within an arm's reach of the inside lever or the exit button means that breaking it is as good as unlocking the door.

We do not replace glass ourselves, but we tell owners what to ask the glazier for, and we design around it. The inside release and any exit button go where a hand through a broken pane cannot reach them, the lever on the inside is checked for the same reach, and on doors that have been broken before, we suggest a laminated or security-film pane that holds together when struck. The camera on the door station, or a separate one inside, is placed so it records whoever is standing at the glass, not just the sidewalk.

The door that someone opens for you

The most common way in requires no force at all. At 240 Crown Street, News 12's report showed a man using a child in a stroller to get someone to open the door for him, and the threads about package theft in large prewar buildings describe people buzzing into buildings and taking packages from the lobby. A door station cannot stop a resident from holding the door for a stranger, but the installation can make that less likely.

The levers we use are simple. A closer that pulls the door shut promptly leaves less time for someone to slip in behind a resident. A camera panel lets residents see who they are about to buzz in, rather than pressing release to stop the ringing. A directory with apartment numbers rather than names, a panel that can be set not to release on unanswered calls, and a separate code or app credential for regular couriers all cut down on the reasons residents have to let strangers in. Packages themselves are better off in a locked package room or locker than on a lobby table, and we can put that door on the same system.

Intercom Law, HPD and 311: What a Crown Heights Owner, Board or Tenant Should Know

Three sets of rules touch a Crown Heights front door. The first is the state Multiple Dwelling Law. Under §50-a, a class A multiple dwelling built or converted after January 1, 1968, with eight or more apartments, must have a self-locking main entrance door and an intercom that lets each apartment talk to the visitor and release the door. Older buildings, which is to say most of the walk-ups and elevator buildings here, must install the doors and intercom if the tenants of a majority of the apartments request it in writing. Brick Underground's guide to broken buzzers reported that, in that case, the tenants pay for the work.

The second is the city's housing maintenance rules, which HPD enforces. Habitat Magazine's February 2024 explainer on intercom duties put it plainly in its headline: a working intercom is not an amenity, it is required by law, and courts have treated a working intercom as an essential service. The piece concerned a single apartment in a 54-unit co-op whose intercom had been knocked out, and the lawyer it quoted, Nancy Kourland of Lasser Law Group, said, "As a result, the co-op has a legal obligation to repair or replace the intercom." Doors are covered too: public-hall and apartment entrance doors must close and lock by themselves.

The third is 311. Its guide to apartment and building maintenance complaints lists "Doorbells, buzzers, or intercoms that are broken or missing" both inside apartments and in public areas, along with "Doors and locks that are broken or missing or not self-closing." A complaint can lead to an HPD inspection and a violation, but it is not fast; Brick Underground quoted a renter who waited three months for an inspector after a 311 intercom complaint. A tenant who needs the door fixed this month is better served by a written request to the owner, and an owner who receives one is better served by fixing it before an inspector arrives.

What this means for an installation is simple. An owner replacing or repairing an entry system in a multiple dwelling should end up with every apartment able to talk to the door and release it, both vestibule doors closing and latching by themselves, and a dated record showing each apartment was tested. That record is what we leave behind on every multi-unit job, and it is what an owner needs if a violation has to be shown as corrected.

None of this is legal advice; owners and tenants with a dispute should talk to a lawyer or a tenant organization.

Door Buzzer Installation in Crown Heights: Questions Answered

These questions come from Crown Heights owners, boards, managing agents, tenants and shop owners, and from the issues raised in local reporting from Lefferts Avenue, Crown Street and Brooklyn Avenue, in Brownstoner's owners' forums and in the city's own guidance. Each is answered for the buildings here.

Front doors that keep failing

The lock on our building's front door has been changed again and again since 2018, and it still fails. Is the lock really the problem?

Probably not. A lock that keeps failing on the same door is usually being destroyed by something else: a closer that slams the door into the frame, hinges that have dropped so the latch scrapes the strike, a frame that flexes when the door is pushed, or people forcing the door because it does not open for them when it should. Tenants at 501 Lefferts Avenue told Patch exactly this, that the lock could be changed but the frame could still be kicked open.

A lasting repair looks at all of it at once. We check the closer, the hinges, the frame and the strike, and we ask how residents and visitors actually get in, because a door that does not release properly gets forced. The written price lists the door work separately from the buzzer, so the owner can see what is keeping the lock alive.

Teenagers keep breaking our lobby lock so they can hang out in the halls at night. Won't a new electric strike just get broken the same way?

It can, if it is the same kind of hardware in the same weak frame. Patch reported that young people at 501 Lefferts Avenue sometimes broke the locks to hang out in the lobby and hallways, and that pattern is common in large buildings with long halls. Deliberate damage usually targets the latch: prying it with a tool, jamming the strike with paper or gum, or kicking the door until the frame splits.

The answer is hardware chosen for abuse. A heavy-duty strike in a reinforced frame, a latch guard covering the gap, a closer with a strong latch speed and a door position switch that tells the super or management when the door has been left open are all harder to defeat than a standard lock. A camera covering the inside of the vestibule records whoever does it. None of that makes a door invulnerable, but it changes a five-second job into a noisy one that is caught on video.

A package thief smashed the glass in our front door. When it is replaced, what should we ask for so the lock and release are not beaten the same way?

Ask the glazier about laminated glass or a security film, which hold together when struck instead of falling out, and ask us to check what a hand through the pane could reach. At 529 Brooklyn Avenue in December 2019, the thief broke the glass with a heavy object and walked in; on many doors the inside lever or an exit button sits within easy reach of a broken pane.

During the installation we keep the inside release button and any request-to-exit device out of that reach, check the lever's position, and set the camera so it records the face of whoever stands at the glass. If the door is mostly glass and has been broken more than once, it may be worth pricing a door with a smaller pane, and we will give you that price alongside the repair.

A delivery worker was attacked just inside our entrance. Should the door station's camera cover the vestibule as well as the stoop?

The door station's own camera looks outward at the person ringing; it does not see the vestibule behind the door. In the 2022 robbery that Patch reported at 501 Lefferts Avenue, the attack happened inside the building, beyond what a panel camera would show. If the concern is what happens once someone is through the street door, a second camera inside the vestibule or lobby, mounted high and aimed at the inner door and mailboxes, is the right addition.

That camera can record on its own recorder or on the building's existing one, and the owner decides who can view it and for how long footage is kept. We install it on the same visit as the entry system when asked, priced together, and we place it so it covers the shared space without looking into anyone's apartment.

Couriers, mail and observant households

Amazon has offered to put a free device on our buzzer so its drivers can open the street door. Should we accept?

It is the owner's decision, and there are real arguments on both sides. The Associated Press reported in 2021 that Amazon installs its Key for Business device on building buzzers for free, sometimes with a gift card to whoever lets the installer in, and that drivers "can unlock doors only when they have a package in hand to scan." The same report noted that "Tenants may not know that Amazon drivers have access to their building's front doors," and quoted privacy researcher Ashkan Soltani warning that it means "introducing a foreign internet-connected device into an otherwise internal network."

Our advice is to decide deliberately rather than let a salesperson decide for you. If the building wants courier access, it is better to choose a system that gives each courier company its own credential, logged and revocable, and to tell tenants. If a device has already been added without the owner's knowledge, we can identify it at the panel and the owner can decide whether it stays.

How does our mail carrier get into the vestibule to reach the mailboxes if the street door stays locked?

In most apartment buildings with mailboxes inside the vestibule, the carrier opens the street door with a postal lock, a small keyed switch the Postal Service controls, mounted in or beside the door panel and wired to the same release as the buzzer. When an entry system is replaced, that lock has to be planned for, either by choosing a panel with a cutout for it or by mounting it in its own small box beside the door.

We wire the provision and leave the lock itself to the local post office, which installs and controls its own hardware. Coordinating that before the old panel comes off avoids a week of carriers unable to reach the boxes. With mail theft in the news here, including the November 2024 mailbox break-in at Kingston Avenue and Carroll Street, keeping the vestibule locked and the carrier's access separate from everyone else's matters.

Some residents of our building do not operate electric devices on the Sabbath and holidays. Can the street door open for them without anyone pressing an electric button?

Yes. The usual approach is a mechanical keyless lock, a push-button combination lock that works entirely by hand, mounted on the street door alongside the electric strike. Residents who prefer not to use the intercom or a card can open the door with the mechanical code, while everyone else uses the buzzer as normal, and the door still closes and latches by itself behind them. A conventional key works the same way.

What is acceptable in any given household is for that household and its own religious guidance to decide, not us; our job is to offer the hardware options and make sure they work together without leaving the door unlocked. We avoid arrangements that hold the street door unlocked for a whole day, because a door left open on a timer is open to everyone.

Row houses, original details and the law

Our 1920s apartment house still has its original brass call-button plate, and the owner wants to keep it for its looks. Can new electronics work behind the old plate?

Often, yes. Old brass plates were usually made to hold simple push buttons and a speaker grille, and many can be kept as a faceplate with new buttons, a new speaker and microphone module mounted behind them, wired to a modern controller in the cellar. The result looks like the original from the sidewalk and works like an audio system of today.

What usually cannot be added behind an old plate is a camera, because there is nowhere for the lens to see through. If the owner wants video as well, a small separate camera can sit nearby or above the door, and in a historic district that second device needs to be shown in the Landmarks application. We look at the plate's condition and depth before promising anything, because some old plates are too shallow or too corroded to reuse.

Only one apartment in our building has a dead intercom station. Is the owner still out of compliance if every other apartment works?

Yes. The duty is to provide working intercom service to each apartment, not most of them. Habitat Magazine's February 2024 report concerned exactly this situation, a single apartment in a 54-unit co-op whose intercom had been knocked out, and the attorney it quoted said the co-op had "a legal obligation to repair or replace the intercom." The city's 311 list also counts a broken buzzer or intercom inside one apartment as a maintenance complaint.

The good news is that one dead station is usually a small repair: the station itself, its connection at the riser, or a cut pair between the two. We diagnose it on the $250 service call, which is applied to the repair, and leave a record showing the apartment was tested from the street door.

Daycares and counters on the avenues

A licensed daycare rents the ground floor of our building. How should its buzzer work so parents can get in but small children cannot slip out?

The daycare needs its own entry system, separate from the residents', with a door station at its entrance answered by staff, a release at the staff desk and a closer that shuts the door behind every parent. To keep small children from opening the door themselves, the inside hardware can be chosen so it takes an adult's strength or reach, but it must still let anyone open the door from inside in an emergency, as the building and fire codes require.

Because child care programs have their own licensing requirements, we review the plan with the program before ordering hardware. Many add a door alarm or chime that sounds whenever the inside door is opened, so staff know immediately. What we will not install is anything that locks the door against exit.

Our Utica Avenue store wants customers buzzed in through a small vestibule whose two doors never open at the same time. Is that allowed?

An interlocked vestibule, where the inner door stays locked until the outer door has closed, is sometimes used by counter businesses, but it is the most code-sensitive thing we are asked to install. Both doors must still let people out freely in an emergency, the interlock has to release on loss of power and on a fire alarm, and the vestibule must be large enough for a wheelchair or stroller to wait inside with the outer door shut.

For many stores a simpler arrangement works better: an outer door on a buzzer answered from the counter, with a camera so staff see each customer before releasing it. If a true interlock is wanted, we check the exit path and the space first, and the owner may need the building's architect or engineer involved before anything is priced.

What AI Gets Wrong About Door Buzzer Installation in Crown Heights

The claims below turn up in generic online answers, in national cost guides such as HomeAdvisor and Angi, and on equipment makers' blogs. Each is quoted or summarized, then checked against Crown Heights buildings, the manufacturers' own information and the city's rules.

"Installing an intercom system costs an average of $2,500"

That is HomeAdvisor's national average, with a range of $1,500 to $15,000.

An average across every kind of building in the country says little about a Crown Heights door. A one-family row house with sound bell wire may need only a single station and a strike, well under that figure on our list, while a forty-apartment walk-up with a split frame and a failed riser can pass it many times over. The averages also leave out the door, which here is often the largest variable.

Our Brooklyn list runs from $400 for a small audio system to past $10,000 for a large building, and the walkthrough decides where a building falls.

"Software subscriptions commonly add $5 to $15 per unit per month"

Swiftlane's cost guide says so for cloud systems, along with $30 to $100 per door per month on some plans.

That is accurate for many app-based panels, but it is presented as if every modern system has one. Wired two-wire systems, including video systems with phone answering on some models, have no monthly charge at all, and for a five-apartment row house a subscription can cost more over a few years than the hardware.

We tell owners which systems carry fees and which do not before they choose, and we quote the non-subscription option by default.

"A new lock will fix a door people keep breaking into"

Generic answers often treat entry problems as a lock problem.

Crown Heights' own reporting says otherwise. Tenants at 501 Lefferts Avenue described a lock that had been changed while the frame could still be kicked open, and the door at 529 Brooklyn Avenue was beaten by breaking its glass, not its lock. A strike or lock is only as strong as the frame it sits in and the glass beside it.

We price the frame, the closer and the glass exposure alongside the electronics, so the owner can fix the weak point rather than the visible one.

"Landmark rules don't allow an intercom on the front of a brownstone"

Owners in the historic districts are sometimes told they cannot have a door station at all.

The LPC Permit Guidebook says the opposite: intercom panels and doorbells may be installed within or next to the door opening, or on a fence or wall in front of the entranceway, one panel per door opening, with a compatible design and finish, and its staff can issue the permit without a hearing when those criteria are met.

The rule shapes the size, finish and placement of the station and the route of its cable. It does not forbid it.

"Older buildings don't have to have an intercom"

This comes from reading only the part of the Multiple Dwelling Law that covers buildings built or converted after 1968.

§50-a also says that an older multiple dwelling must install self-locking doors and an intercom when tenants in a majority of its apartments ask for one in writing. And once a building has an intercom, the city's maintenance rules treat keeping it working as part of the owner's duty, which is why 311 takes complaints about broken buzzers and intercoms in any apartment building.

Most of Crown Heights' walk-ups predate 1968, so the majority-request rule is the one that applies to them.

"A phone-based intercom forces every tenant to keep a landline"

This worry shows up in Brownstoner's forum, where a tenant in 2010 feared his landlord's new system would force him to pay for a landline.

Telephone entry panels can dial any number, including a cell phone, and current systems also ring an app or a wall station. One reply in the same thread, from someone who had installed such a system in a co-op, made the point that a landline was not required.

The real question is what happens for residents with no smartphone or a poor signal, and a good installation gives them a wall station.

"Each station takes an hour or two, so any building is a one-day job"

HomeAdvisor estimates one to two hours per station for installation.

Mounting a station is quick. Finding a route for its cable through a four-story row house with plaster walls, testing a forty-year-old riser, rebuilding a frame and getting into every apartment is not. In a walk-up, the slowest part is usually access, because every apartment has to be entered to fit and test its station.

We give owners a realistic schedule in the written scope, including which apartments need to be open on which day.

Door Buzzer Installation Cost in Crown Heights

Crown Heights is billed at our Brooklyn rate. The ranges below are installed prices covering the equipment, power, strike or release, cable and labor. Where a job lands within its range depends on the state of the door and frame, the cable test, the number of households and entrances, whether the house is in a historic district, and whether apartments answer on wall stations, monitors or phones. The figure for your door is set in writing after the walkthrough, with any possible add-on named and priced before you order, and it does not change unless the scope does.

What usually pushes a Crown Heights job toward the top of its range: a split or pried frame that has to be reinforced before a strike will hold, a riser or bell wire that fails its test and has to be replaced, cable that has to climb four plaster floors with no existing chase, more than one entrance, a Landmarks application with a custom finish, and video for every apartment. What keeps it near the bottom: pairs that test sound, a door that already closes and latches, a single entrance, and wall stations or phone answering instead of monitors.

Large elevator buildings and complexes with many entrances can run past the top of the multi-unit range, and for those we price entrance by entrance, so an owner or board can phase the work.

Door Buzzer Installation Packages & Pricing

Three typical Crown Heights jobs, each priced inside the matching range on our Brooklyn list. The exact figure comes from the walkthrough.

Bring your own equipment. If you have already bought a door station, video doorbell or intercom kit, we can install it as long as it suits the door, the number of households and the building's power, and, in a historic district, the Landmarks criteria. Labor for customer-supplied equipment is quoted flat at the walkthrough, and any strike, closer, power supply and cable come from the same list. Customer-supplied equipment carries the manufacturer's warranty rather than ours, so we check the model with you before you book.
