Door Buzzer
Installation in
Clinton Hill

Quick answer: door buzzer installation in Clinton Hill runs $400 to $900 installed on our Brooklyn list for an audio system with talk-back on a brownstone of one to four apartments, $700 to $1,800 for a video door station with indoor monitors or phone answering, and from about $2,500 to past $10,000 for a prewar apartment house or a divided mansion with a directory panel and a station in every unit. Each price covers the door station, the stations inside, the power supply, the electric strike or release, the cable and the labor. The number is written down after a walkthrough, and any possible add-on, such as replacing an old run of wire that might fail its test or repairing a door that does not latch, is named before you order, so nothing new turns up on installation day. Clinton Hill pays the regular Brooklyn rate. What pushes a job higher here is usually the house itself: a doorway in the historic district where the cable has to stay hidden, original glazed doors that need a careful release, a long route from the cellar to a fourth-floor apartment, or video for every household. Text photos of the doorway and the old panel to (347) 934-8335 or send them on WhatsApp, and we reply with the range that fits, usually within two hours during working hours.

• Looking at photos and quoting a new buzzer costs nothing. When an existing system is dead and must be diagnosed 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; if a doorway needs a new 120-volt circuit for its power supply, a licensed electrician handles that part, and we say so before pricing.
• We work for whoever owns the door: the homeowner, the condo or co-op board, or the owner or managing agent of an apartment house. A renter who wants a buzzer should ask the owner to call us, because the owner has to authorize the work on the building.

Need Repair in Clinton Hill? A Panel That Hums, a Handset That Rings but Will Not Release, or a Door That Swings Free

Many Clinton Hill calls start as "we need a new buzzer" and turn out to need one part. Brick Underground's guide to fixing New York intercoms lists the three usual complaints, which are that the caller cannot be heard, that the resident cannot be heard, or that the lobby door will not unlock, and the installers it interviewed said the core wiring is usually fine even in old systems; one of them put it simply: "It's all in the wire connections." In a brownstone that has been painted, re-pointed and rewired around its buzzer for sixty years, a loose splice in the cellar, a tired transformer or a strike that has drifted out of line with its latch accounts for a lot of dead systems.

So before we quote a full installation on a house that already has a system, we look at whether the old one can be brought back. If it can, we say so, and the repair is priced against our separate repair list. If the system is beyond saving, if the owner wants video, or if the house has been divided into more apartments than the old panel has buttons, the walkthrough turns into an installation quote. If your street door will not lock today, say so when you call (347) 934-8335. A diagnosis of an existing system is the $250 service call booked online, and that $250 is credited toward whatever work follows. Brick Underground also notes that the building must authorize any repair, so a tenant whose buzzer has stopped should report it to the owner or managing agent, who can then book the visit.

Door Buzzer Installation for Clinton Hill's Architecture

Six kinds of building make up nearly all of our Clinton Hill work. Each has its own entry problem, and the house decides the plan far more than the brand of panel does.

Divided brownstones: the parlor door, the vestibule and the stoop

A typical Clinton Hill brownstone has a stoop up to a pair of outer doors at the parlor floor, a small vestibule, and an inner door into the stair hall. The garden apartment usually has its own door tucked under the stoop behind an iron gate. When the house was divided, someone screwed a bell board to the brownstone beside the outer doors, ran wire through the facade or down the stoop, and put a handset in each apartment. Sixty years later the board is often corroded, the wire may have been painted over or cut during a renovation, and the handsets ring but no longer release.

The installation answers that with a single panel, one button per apartment, at the parlor door, and a release on the door the household agrees should be the security line. In most brownstones that is the inner vestibule door, because the outer doors are original, often glazed and frequently left open during the day, while the inner door is the one that locks. If the garden apartment has its own door, it either gets a second panel at that opening or shares the parlor-floor panel with its own button and a release on its own door.

The cable is the part that takes judgment. Brownstone facing is soft sandstone over brick, and the Landmarks rules want conduit to pass through plain masonry behind the panel rather than run across the front. So we look for a mortar joint or a plain area beside the door, go straight through to the vestibule or the cellar, and keep every inch of cable inside the house.

Single-family townhouses: one door, four floors and a garden

A house with one family still needs a way to answer the door that does not involve running down three flights. Brownstoner's 2024 feature described an 1870s Clinton Hill row house gutted for "a growing family of four," with only the entry and vestibule doors and one mantel salvaged; houses like that are good candidates for a video door station with a monitor on the parlor floor and the top floor, and phone answering for anyone in the garden or away from home.

The trap in a one-family house is relying on a battery doorbell camera alone. It rings phones, but it does not release the door, and it often loses its Wi-Fi signal through the brownstone and brick between the front of the house and a router at the back. A wired door station with a strike on the inner door does both jobs, and it can still send the picture to phones if the family wants that.

Divided mansions: one grand entrance, many households

The mansions along Clinton Avenue and parts of Washington Avenue were built for single wealthy families and later divided, some into a few large apartments and some into a dozen or more units. Their entrances are often the most elaborate in the neighborhood, with carved stone surrounds, heavy double doors and sometimes a porch or porte-cochère. The panel has to sit somewhere plain, and the release has to hold a door far heavier than a row-house door.

The number of apartments also brings the city's rules into play. Multiple Dwelling Law §50-a requires an intercommunication system in Class A multiple dwellings of eight or more apartments erected or converted after January 1, 1968, so a mansion divided into eight or more apartments after that date is required to have one. We check the certificate of occupancy before pricing, because it tells us both the legal unit count and the date of conversion.

Prewar apartment houses: risers, lobbies and fifty doors at once

Clinton Hill's apartment houses range from small walk-ups to six-story elevator buildings like 476 Clinton Avenue, which Openigloo lists at 52 units built in 1913. These buildings already have a riser of multi-pair cable running up through the building, and the main question is whether it can carry a new system. Aiphone's guidance for its GT Series says existing wire in good condition can be reused, and the Security Sales report on Park Vanderbilt, a 148-unit co-op in nearby Park Slope, describes an installer reusing most of the old cable and saving about $20,000. We test every pair before saying the riser stays.

Where the riser is sound, the job is a new lobby panel, new apartment stations and a new power supply, often finished in a day or two. Where it is not, new cable goes up a closet stack, a dumbwaiter shaft or the public hall in a painted raceway, and the price reflects that from the start.

Wood-frame and carriage houses: set back from the street

Some of Clinton Hill's oldest houses are wood-frame, and a number of former stables and carriage houses have become homes. Their front doors are often behind a gate, down a path, or at the back of a narrow lot. A visitor has to be able to ring from the sidewalk, which means a station at the gate and either a release on the gate itself or a clear path to a front door the family can open by voice.

Wood siding and frame walls make the cable work easier than in a brownstone, but the distance from the gate to the house is the cost driver. We price a buried or fence-run cable from the gate, or, where trenching is out of the question, a station that runs over the house network.

Co-op and condo buildings: who decides and who owns the door

Small brownstone condos of two or three units often have no managing agent, so the owners have to agree among themselves on the system, the cost split and who holds the administrator login. In co-ops, the decision belongs to the board, and the obligation is clear: Habitat Magazine's February 2024 article on intercom law quoted attorney Nancy Kourland: "As a result, the co-op has a legal obligation to repair or replace the intercom." The same article said a shareholder is unlikely to be responsible for intercom repairs.

For any co-op or condo, we give the board a written scope that names every component, the cable plan and the warranty, and we keep the admin access with the board or its agent rather than one resident's phone.

One Panel, Hidden Cable, Nothing on the Carving: Fitting a Buzzer to a Clinton Hill Landmark Front

Owners in the historic district often assume the Landmarks Commission will make a buzzer difficult. In practice, a door station is one of the more straightforward things to get approved, because the Commission has written down what it accepts and its staff can issue the permit without a public hearing when the work meets those rules. The rules are in Chapter 11 of the LPC Permit Guidebook, the chapter on health and safety installations, and they are short enough that every owner should know them before talking to any installer.

Where the panel can go. The guidebook says intercom panels and doorbells "must be installed within or adjacent to a door opening," and adds that "an intercom can also be installed on a fence or wall in front of the entranceway." On a Clinton Hill brownstone that gives three realistic places: on the plain stone or brick beside the parlor-floor doors, inside the door opening on the jamb or in the vestibule if the outer doors stay open by day, or on the iron fence or low wall at the front of the areaway. The right one depends on the house: the fence suits a house whose stoop is long and whose garden door also needs a button, while the jamb suits a narrow front with no plain stone to spare.

How many panels. The rule is "a maximum of two light fixtures and one intercom panel" per door opening. That means a divided brownstone with four apartments gets one four-button panel at the parlor door, not a row of separate doorbells, and that two owners in a small condo cannot each put up their own brand of panel at the same doorway. A garden door under the stoop is a separate opening and can have its own panel.

What it may look like. The design, size and finish must be "compatible with the architecture of the building," which the guidebook explains as neutral and discreet. A brushed or dark finish, a slim profile and no glossy logo plate are what we propose. Large brass bell boards from the middle of the last century are often bigger than anything a modern panel needs, which helps: a smaller panel can cover the old holes, or the old holes can be patched by a mason.

Where the cable goes. If conduit is needed, it "must be concealed" by going through plain masonry or wall cladding behind the installation. Only where that is impossible may staff approve about ten inches of visible conduit, painted to match the surface, and never on decorative surfaces. Equipment "must not be attached through cast iron or on any decorative surfaces," which rules out the carved brownstone surround on many Clinton Avenue houses and the cast-iron newel posts and railings on the stoops. The practical answer is almost always a straight hole through a plain section of wall or a mortar joint, directly behind the panel, into the vestibule or down into the cellar.

What the permit needs. We give the owner, or the architect or expediter if one is involved, a photo of the doorway with the panel's position marked, the product sheet with its dimensions and finish, and a note of the cable path. If a proposal does not meet the rules, the guidebook says staff may suggest alternatives that do, or the proposal may go to the full Commission at a public hearing; we design to the rules from the start so that does not happen.

Blocks outside the city district. Not every old block in Clinton Hill is a city historic district. The rows on Lefferts Place and Brevoort Place between Washington Avenue and Bedford Place make up the Clinton Hill South Historic District, which is listed on the National Register of Historic Places, and BKMag reported in June 2012 that the Landmarks Commission rejected a proposed Lefferts Place district, with a spokesperson citing "a number of empty lots or other intrusions that disrupt the cohesion of the streetscape." National Register listing by itself does not bring the city's permit requirement, but individual landmarks still do: 70 Lefferts Place was designated in December 2006. We check every address against the city's landmark maps before pricing.

What New York's Intercom and Door Rules Ask of Each Clinton Hill Building

The legal picture in Clinton Hill depends on how many apartments a building holds and when it reached that number. Most of the confusion we hear comes from owners of small divided brownstones who have been told they must have a video intercom, and from owners of larger buildings who assume a working bell is enough.

One- and two-family houses. These are private dwellings, outside the Multiple Dwelling Law's intercom section. No law requires a buzzer, but a working, latching street door is the owner's job, and a two-family with a tenant is much easier to run with one.

Three to seven apartments. A building with three or more households living independently is a multiple dwelling, so a brownstone divided into three or four apartments is one. The multiple dwelling rules on entrance doors begin to matter at that point, and if it is a Class A multiple dwelling built before 1968, its tenants may be able to trigger the intercom requirement themselves through the written majority request described below, so we check the building's classification before advising.

Eight or more apartments. Multiple Dwelling Law §50-a says every Class A multiple dwelling erected or converted after January 1, 1968 with eight or more apartments "shall also be equipped with an intercommunication system" at its self-locking main door, allowing voice communication and remote release. For older buildings, the same section requires the doors and intercom once tenants occupying a majority of the apartments request it in writing, with installation started within 90 days and completed within six months. A Clinton Hill mansion divided into eight or more apartments after 1968 falls into the first group; a 1913 apartment house falls into the second.

Keeping it working. Habitat Magazine's February 2024 article reported that courts have treated a working intercom as an essential service under the warranty of habitability. For rent-stabilized buildings, tenants can also pursue a rent reduction through the state's housing agency when an intercom stops working, which is one more reason to install a system that is easy to maintain.

App and fob systems. HPD's Tenant Data Privacy Law applies to multiple dwellings that use smart access, or keyless, systems. Owners may collect only the minimum data, such as the user's name and "the time and method of access, solely for security purposes," must get express consent in writing or through the app, must give tenants a data retention and privacy policy, and must destroy authentication data within 90 days unless it is anonymized. We set app-based systems up so the owner can meet those rules from the first day.

Reach and accessibility. The 2010 ADA Standards put the high forward reach at 48 inches maximum and the low forward reach at 15 inches minimum, and operable parts must fall within those ranges. We mount panels within that band, which also suits children and older residents.

Door Buzzer Installation in Clinton Hill: Questions Answered

These are the questions Clinton Hill owners, boards and renovating families ask us most often about putting in a new buzzer, grouped by the situation they come from. Each answer is the one we would give on the phone.

Renovations, conversions and houses going back to one family

We are turning our three-apartment brownstone back into a single-family house. What should happen to the old buzzer?

Take it out, and plan the new door system as part of the renovation rather than after it. A house that goes back to one family no longer needs a button per apartment, but it still needs a way to answer the door from the top floor, the kitchen and the garden, and it usually needs a release on the inner vestibule door so the family can let in a delivery or a guest without walking down. A single-button video station with monitors on two floors and phone answering is the most common choice we install in houses like this.

The old bell board can come off the facade, and its holes either sit under the new, smaller panel or are patched by the mason who is already working on the front. The old handsets, wire and transformer come out during demolition, which is far cheaper than chasing them later. If the house is in the historic district, the new panel goes on the Landmarks drawing with the other front work, so one permit covers it.

Our architect is drawing a gut renovation. What does the buzzer need on the plans before the walls close?

Four things. First, the panel's location on the elevation of the doorway, with its dimensions, so the Landmarks staff and the mason know exactly where the stone will be penetrated. Second, a sleeve through the front wall directly behind the panel, set while the masonry is open, so the cable is concealed as the guidebook requires. Third, a cable route from that point to the cellar or a closet stack, and from there to every floor that will have a station, drawn as a dedicated low-voltage path. Fourth, the power supply's location on a cellar wall near an outlet on the owner's circuit.

We can walk the house with the architect during framing, mark the box locations, and leave pulled cable coiled at each point with labels, so the finished system is installed in a day once the painting is done. Doing it this way is almost always cheaper than fishing cable through finished plaster, and it avoids surface raceway in rooms that were just restored.

Our Clinton Avenue mansion was divided into nine apartments in the 1980s. Does the date of the conversion mean the law requires an intercom?

Very likely yes. Multiple Dwelling Law §50-a applies the intercom requirement to Class A multiple dwellings of eight or more apartments that were erected or converted after January 1, 1968. A mansion that became nine apartments in the 1980s fits both parts of that test, so the building should have self-locking main doors and an intercom that lets each apartment talk to a visitor and release the door.

The certificate of occupancy usually confirms both the number of apartments and when the conversion was legalized. If the building has a working system, the obligation is to keep it working; if it has only a bell board, or nothing at the door at all, a proper installation should be planned. We price these buildings on the apartment-house end of our list, from about $2,500 upward depending on the number of units and the state of the wiring.

Can the new cable go up the old dumbwaiter shaft or a stack of closets instead of through the rooms?

Often, and those are the two routes we look for first in a Clinton Hill brownstone. A dumbwaiter shaft that has been closed off still runs from the cellar or kitchen level to the upper floors, and a stack of closets placed one above another gives a hidden path through each floor. Either keeps the new cable out of restored rooms and away from plaster cornices and woodwork.

The route still has to be safe: holes between floors are sealed again with fire-stopping, and the cable stays away from gas lines and old knob-and-tube wiring if any remains. If neither route exists, the stair hall is the next choice, with the cable carried along the base or the ceiling line in a small painted raceway that blends into the trim.

The front of the house

Our doorway has glass sidelights on both sides and a transom above. Where does the panel go if there is no solid stone next to the door?

Usually on the plain masonry pier just outside the sidelights, on the jamb inside the door opening, or on the areaway fence. The Landmarks rules allow a panel within or adjacent to the door opening or on a fence or wall in front of the entrance, so a doorway that is glass from edge to edge still has options, but the panel never goes on the glass or on the wood of the sidelight frame.

When the pier is carved or too narrow, the fence is often the neatest answer, because it puts the panel at sidewalk level where visitors stand and keeps the facade untouched. The cable then runs under the areaway or the stoop to the cellar. On houses outside the district we use the same logic, because it simply looks better.

Our block is listed on the National Register. Is that the same as being landmarked by the city when it comes to a buzzer?

No. National Register listing is a federal recognition, and by itself it does not require a permit from the city's Landmarks Preservation Commission for work on a private house. The Lefferts Place and Brevoort Place rows that make up the Clinton Hill South Historic District are on the National Register, and BKMag reported that the Commission declined to create a city district there in 2012.

The exceptions are buildings the city has designated one by one, such as 70 Lefferts Place, designated in December 2006, and any block that is inside a city district. We check each address before quoting. Even where no permit is needed, we still follow the same placement and concealment habits, because they protect the facade and the house's value.

My mother uses a wheelchair and comes in through the garden door under the stoop. Can her visitors be sent to that door?

Yes. The garden door is a separate opening, so it can have its own panel with her apartment's button, and the parlor-floor panel can carry a label directing visitors for her unit to the garden entrance. Her station inside can sit at a height she reaches from the chair, and the release on her door can be paired with a closer that is light enough for her to open.

If the garden door opens straight into her apartment, the release goes on that door. If it opens into a shared cellar hall, the release goes on the inner door to her rooms, so the rest of the house stays locked. We mount every button within the 15- to 48-inch reach range of the 2010 ADA Standards so she can use the panels herself when she comes home.

Tenants, students and app-based systems

Our new tenants arrive from out of state the week before classes start. Can they be set up on the entry system before they ever see the building?

On an app-based or networked system, yes. The owner or manager can add each tenant by email or phone number from the admin login, assign them to their apartment, and send the invitation before they arrive, so the first time they ring from the sidewalk the call reaches their phone. When they move out, the same login removes them in a minute, which matters in a neighborhood where many apartments change hands each August.

On a wired audio or video system with stations in the apartments, there is nothing to set up except the label on the panel, which the owner can change, and the station in the apartment simply works. For houses rented to students, we often recommend a wired station in each apartment plus optional phone answering, so the door works whether or not a tenant installs an app.

We are buying a building with a phone-based intercom whose subscription is about to lapse. What happens at the door if nobody pays it?

It depends on the system, and it is worth asking the seller for the account details before closing. Many cloud panels keep releasing the door for codes or cards stored in the panel, but stop calling residents' phones or stop letting the manager edit the directory once the subscription ends, which leaves tenants with no way to answer a visitor. Habitat Magazine reported one smartphone system's fee at $2.50 per unit per month, so the cost of keeping it is usually small next to the cost of replacing it.

If the system is old, unsupported or tied to a former owner's account that cannot be transferred, we price a replacement that the new owner controls from day one. If it is sound, we can usually take over the setup once the account has been moved, and add wired stations for tenants who do not want an app.

What AI Gets Wrong About Door Buzzer Installation in Clinton Hill

These claims turn up in generic online answers, national cost guides and vendor blogs when people search for buzzer or intercom installation. Each is true somewhere; here is how it holds up on a Clinton Hill doorway.

"Wireless systems are the best option if you want to DIY"

HomeAdvisor's intercom cost guide says exactly this, and for room-to-room intercoms inside a single house it is reasonable advice.

A buzzer for a shared Clinton Hill door is a different thing. The part that matters is the release on the door, and that needs power and a wired connection to a strike set into the frame. Wireless units also have to get a signal through brownstone, brick and plaster, and the panel itself, on a landmarked front, needs a permit and a concealed cable path that a wireless kit does not solve.

Wireless chimes can help a one-family house hear the bell on the top floor. For a house with tenants, the door needs a system that rings each apartment separately and lets each one open the door, and that is a wired job.

"Allow one to two hours per station"

HomeAdvisor puts installation at about one to two hours per station, which is a fair figure for mounting a unit on a prepared wall.

On a brownstone, the stations are rarely what takes the time. The hours go into the door, getting an old inner door to close and latch, setting a strike in a century-old frame, and into the cable, finding a hidden path from the cellar to a fourth-floor apartment without opening restored plaster. A three-apartment house can take most of a day for those reasons, even with only four devices.

That is why we price after a walkthrough rather than by counting stations, and why the quote names the door work and the cable route as their own lines.

"Modern IP or video systems cost $1,000 to $5,000 or more per entry door"

Swiftlane's apartment intercom cost guide gives that range per door, with software fees on top, and for networked panels in larger buildings it is a fair description.

A Clinton Hill brownstone with two to four apartments seldom needs that kind of system. On our Brooklyn list, a video door station with indoor monitors or phone answering for a house like that runs $700 to $1,800, and an audio system with talk-back runs $400 to $900. The higher figures belong to prewar apartment houses and divided mansions with dozens of units, which start around $2,500 on our list.

Budgeting a small house from a per-door figure written for large buildings tends to scare owners away from a job that costs far less than they fear.

"A smartphone intercom costs about $5,000 to $7,000 plus a small monthly fee"

Habitat Magazine's May 2017 article on smartphone intercoms cited about $5,000 to $7,000 for one installation, with a monthly charge of $2.50 per unit, in the context of a 12-unit Harlem condominium.

The figure is real, but it describes one building of a particular size. In the same article, Dan Arnold of Academy Mailbox said, "A lot of our calls now are people who want to abandon the hard-wired intercom units in their apartments," which captures why owners ask, but a three-unit Clinton Hill house rarely needs a cloud panel to get phone answering, because many wired video systems can also ring phones without a per-unit subscription.

We price wired and app-based options side by side for any owner who asks, with the monthly cost written out over five years, so the choice is made on the full number.

"You can't put a modern intercom on a landmarked brownstone"

This one comes up in forum answers and general advice more than in official sources, and it stops owners from fixing doors that badly need it.

The Landmarks Preservation Commission's own guidebook says staff can issue permits for intercom panels, and lists the conditions: within or adjacent to the door opening or on a fence or wall in front of the entrance, one panel per opening, a neutral and discreet design, and concealed conduit. A slim modern panel placed on plain masonry with its cable through the wall meets those conditions on most Clinton Hill fronts.

What the Commission does not accept is clutter: several boxes at one door, conduit across the facade, or anything fixed to carved stone or cast iron. Design to the rules, and the permit is a routine staff-level approval.

"A magnetic lock is the simplest way to add a buzzer to a door"

Magnetic locks mount on the surface without cutting into the frame, so online answers often present them as the easy option for old doors.

They come with obligations. Allegion's guide notes that "electromagnetic locks are only available fail safe," so the door unlocks whenever power fails, and the building code's sensor-release rules call for a sensor on the inside, a push-to-exit button within reach, release on power loss and release on fire alarm. On a brownstone, that is a lot of extra hardware on a historic door, and it leaves the house open during a power cut.

A fail-secure electric strike, set carefully into the frame, stays locked without power, leaves the inside lever free for anyone leaving, and keeps the door's appearance unchanged. That is what we recommend for almost every Clinton Hill street door.

"Old wiring can simply be reused"

Aiphone's own guidance for its GT Series says existing wire in good condition can be reused, and Brick Underground's installers said the core wiring in old systems is usually fine.

The words that matter are "in good condition." In a Clinton Hill brownstone, the old bell wire may have been cut in a renovation, painted into the facade, spliced in the cellar a dozen times, or simply never run to the apartment that was added later. In an apartment house, a riser may have a few dead pairs that only show up under test.

We test every pair before pricing and write down which wire is being reused and which is new. If a run might fail when the new system goes on, the cost of replacing it is named in the quote, so the owner knows the worst case before ordering.

Door Buzzer Installation Cost in Clinton Hill

Clinton Hill is billed at our Brooklyn rate. The ranges below are the published Brooklyn door buzzer list; every job gets a written number inside the matching range after a walkthrough, with any possible extra named before you order.

What moves a Clinton Hill job toward the top of its range: a doorway in the historic district where the cable has to be taken through stone and kept hidden, an original inner door that needs rehanging before a strike will hold, old wire that fails its test so a new route is needed, a garden door added to the system, and video monitors for every apartment. What keeps it toward the bottom: old wire that tests sound, a door that already latches, a renovation that leaves the walls open, and audio stations or phone answering instead of monitors.

A Brownstoner forum thread on a three-unit house's failing buzzer reported a $2,000 replacement estimate "without any electrical work"; another owner of a two-upper-unit brownstone recalled quotes from more than $1,500 to closer to $3,000 for video. Those figures sit inside the range of real Brooklyn prices for small houses, which is why we put every line of the scope in writing: the owner can compare what each quote actually includes.

Door Buzzer Installation Packages & Pricing

Three typical Clinton Hill jobs, each priced inside the matching range of the Brooklyn list. The exact figure for your house is set after the walkthrough.

Bring your own equipment. If you have already bought a door station, video doorbell or intercom kit, we can install it as labor only, quoted by phone or text from photos of the door, the product and the old wiring, and booked with a deposit. We check first that it can release your door, that it suits a landmarked front if the house is in the district, and that it will work over the wire in the house. Equipment you supply is covered by its maker's warranty rather than ours, and we say plainly before you book if it will not do the job.
