Door Buzzer
Installation in
Cobble Hill

Quick answer: door buzzer installation in Cobble Hill costs $400 to $900 installed on our Brooklyn list for an audio buzzer with talk-back on a rowhouse with one to three households, $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 walk-up, a courtyard building or a condo with a panel at the entrance and a station in every apartment. Each price covers the door station, the stations inside, the power supply, the strike or release, the cable and the labor, and it is fixed in writing after a walkthrough, with any possible extra, such as a cable pair that may not pass its test, named and priced before you order. Cobble Hill is billed at the Brooklyn rate with no travel premium. What moves a Cobble Hill job up the range is rarely the electronics: it is a front door that has to latch properly before any release will hold, a landmarked doorway where the cable must stay hidden inside plain masonry, a house whose unit count is changing so the button plate has to be redesigned rather than copied, and video for every household instead of one. Send photos of the doorway, the button plate and the frame to (347) 934-8335 or on WhatsApp, and we reply with the range that fits, usually within two hours of your message during working hours.

• Looking at your photos and quoting a new buzzer costs nothing. If an existing system is dead and has to be diagnosed first, that is the $250 service call booked online, and the $250 is applied toward the work.
• All work falls under New York State license #12000287431. We install low-voltage entry equipment only; if a doorway needs a new 120-volt outlet for its power supply, a licensed electrician does that part, and the written price says so.
• We work for whoever controls the door: the owner of a rowhouse, the board or managing agent of a condo or co-op, or the owner of a walk-up or mixed-use building. In a rental apartment, the request has to come from the landlord or with the landlord's written agreement.

Need Repair in Cobble Hill? Buttons Ringing Empty Floors, a Panel Nobody Can Hear, or a Release That Clicks and Stays Shut

Not every Cobble Hill call ends in a new system. Brick Underground's guide to NYC intercom repair sums up the three complaints we hear most: "You can't hear your guest, they can't hear you, or the lobby door isn't unlocking." Pete Carmello of Lock and Tech, a Brooklyn company, told the guide that "a lot of times it's user error," such as a button not held long enough, and Daniel Vasquez of Paragon Security and Locksmith said "it's all in the wire connections," at the door, at each station, at the strike and at the power supply. In a rowhouse that has been renovated two or three times, add a fourth cause: a splice buried behind a new wall by the last contractor, or a pair cut when a floor was combined with the one above it.

If the door will not lock right now, say so when you call (347) 934-8335. A diagnosis is the $250 service call booked online, and the $250 goes toward the repair, or toward a new system if replacing turns out to be the better value. You get both numbers and a straight recommendation. If a part has to be ordered, we leave the door able to lock and open with a key before we go. For a rental building where the intercom is part of an open HPD violation, we give the owner a dated record of what was found and what was done, the record an owner needs when certifying that a condition has been corrected.

Door Buzzer Installation for Cobble Hill's Architecture

Six kinds of property make up nearly every door buzzer job we would quote in Cobble Hill. Each puts the door station, the cable and the stations inside in different places, and each has its own common mistake.

Rowhouses divided into floor-throughs: the stair is the riser

A floor-through house is the Cobble Hill door buzzer job in its classic form. The street door at the top of the stoop opens into a small vestibule, an inner door opens onto the stair hall, and each floor above has one apartment whose door faces the stair. The button plate sits beside the outer door, and somewhere in the house, usually in the cellar under the stoop or in a closet at the back of the parlor floor, a transformer or power supply feeds a cable that runs up the stair hall wall to each apartment.

In these houses the stair hall is the riser, and that is good news for the owner. A stair hall wall between floors is usually lath and plaster over a framed partition or a chase beside the stringer, and a cable can be fished through it from the cellar to each landing without opening an apartment's walls. Dan Arnold of Academy Mailbox put the general rule plainly to Habitat Magazine in 2017: "If it's sheetrock, you can make a few holes and snake it down to the basement," and with harder walls, "nothing is insurmountable." Plaster takes longer than sheetrock and needs smaller, more careful holes, but the route is the same.

Houses returning to one family: fewer buttons, more places to answer

When a rowhouse goes back to being a single home, the owners usually want the opposite of what the old system did. Instead of four buttons each ringing one floor, they want one button that rings everywhere: a monitor in the kitchen on the garden level, another on the parlor floor, one upstairs near the bedrooms, and the call on both owners' phones. On a five-story house, the difference between hearing the door on the floor you are on and hearing it two floors down is the difference between a delivery left on the stoop and one handed over.

There is often a middle step. Many owners combine the upper floors into a triplex and keep the garden apartment as a rental, or use it as the "guest suite" Brownstoner said was appearing on more floor plans. For that house we fit two buttons: one for the owner's home, ringing a group of stations on its floors, and one for the garden, with its own station and release, and often its own door under the stoop. If the garden may become family space later, its button can simply be added to the owner's group by a setting change, without a new plate.

Sidewalk-front houses and former stables: a doorbell on the public walk

Verandah Place is the clearest example in the neighborhood. Untapped New York's history of the street describes a service alley laid out before the Civil War, about 20 feet wide including its narrow south sidewalk, with a row of small brick houses, mostly three stories, "built up to the sidewalk," and notes that "some of these structures were originally built as stables and later converted to residential use." Cobble Hill Park sits across the street. A house like that has no stoop to lift the doorway above the sidewalk and no areaway between the door and the people walking by.

That changes the station. On a stoop, a door station is out of reach of passing strollers, bags and dogs; on a sidewalk-front house it is at shoulder height on a public walk. We use flush or low-profile stations with metal faces, set them on the hinge side of the door where they are less likely to be brushed by people passing, and choose models whose buttons need a deliberate press. Former stables also often have a wide original opening, sometimes with a smaller door set into a larger pair, and we look at which leaf people actually use before deciding where the release goes.

Courtyard complexes on Hicks Street: the outside panel has to earn its keep

The Cobble Hill Association's history of the Tower and Home Buildings describes model tenements built by Alfred Tredway White, the Home Buildings in 1876 and 1877 on Hicks and Baltic Streets and the Tower Buildings and cottages in 1878 and 1879, with exterior stairs and balconies around large courtyards and stores on the Hicks Street side. They had 218 rental units when built and, after a restoration from 1978 to 1986, 188 apartments. Warren Place, the gated mews of 34 brick cottages between Warren and Baltic Streets described by 6sqft in 2015, belongs to the same family of buildings.

In complexes like these, the panel outside is doing a hard job. A visitor stands at a street gate, the call goes to an apartment that may be across a courtyard and up two flights of an open stair, and the resident has to hear and be heard over Hicks Street traffic. The one tenant review on Openigloo's listing for 439 Hicks Street calls the building's "outside intercom" horrible. We cannot know what failed there, but the usual causes of a bad outside panel are well known to us: a speaker and microphone worn by decades of weather, a panel mounted where wind or traffic noise drowns the visitor, and an old, long cable run that loses signal before it reaches the farthest apartments.

Church and school conversions: tall doors and inherited systems

Cobble Hill has several former houses of worship and schools now used as homes. Wikipedia's entry for the neighborhood notes that St. Peter's church and school on Hicks Street became condominiums and that the Strong Place Baptist Church became apartments. CityRealty lists The Landmark at Strong Place, at 58 Strong Place, as 23 condominium units on four stories, with an elevator, a mail room and a "virtual doorman" among its amenities, and no doorman.

Two things make these buildings different for a buzzer installer. The first is the door. Church doors are tall, heavy and often original, set in deep masonry, and they need a release and a closer chosen for their weight, not for an ordinary rowhouse door. The second is the system itself. A conversion's entry equipment was chosen by the developer, sometimes tied to a remote-attendant service, and when the service contract ends or the board takes over, the board may find it has a panel it cannot program and nobody who knows the passwords. We start those jobs by finding out what the building owns, what still works, and what can be kept.

Shops with apartments above: two doors, two systems

Court Street and Smith Street are Cobble Hill's main shopping streets, and Atlantic Avenue along the northern edge is known for one of the city's largest collections of Middle Eastern shops. Many buildings on those streets have a storefront at street level and a narrow residential door beside it leading to two or three apartments upstairs. The apartments get their own small panel at their own street door, wired up their own stair, with the power supply in the part of the building the owner controls. The shop gets a separate delivery buzzer at its back or side door, answered at the counter or on a phone.

When a Cobble Hill House Changes Its Number of Homes: Buzzers Through Combining, Dividing and Renting Again

The buzzer is one of the last things anyone thinks about when a rowhouse changes its layout, and one of the first things a visitor touches. Brownstoner's 2013 report on townhouses "coming full circle" described owners taking back floors that had been rented for decades; Cobble Hill's sales since then, including the $16 million single-family conversion PincusCo reported in June 2026, show the same direction. In practice we meet four situations, and each wants a different kind of system.

A full return to one family. The house becomes a single home from the garden to the top floor. The doorway gets one button, and the call rings a group of stations and phones. Because the old cable already reaches every floor, most of the work is inside: monitors where the family spends its time, usually the garden-level kitchen and the parlor floor, a station on the bedroom floor, and phone answering for when nobody is home. The old multi-button plate comes off and the new single-button station goes into the same position or a better one, with the old holes filled and finished by the mason or painter you choose.

An owner's triplex over a garden rental, or under a top-floor rental. This is the commonest middle step. The owner takes two or three floors and keeps one apartment for income or for family. The plate gets two buttons, clearly labeled by floor or letter rather than by name. The owner's button rings the owner's group; the rental button rings only the tenant's station and phone. Each household gets its own release, and the owner's monitors are set so they show the doorway only on the owner's own calls. If the rental has its own door under the stoop, its button can go there instead, and the main door's plate shrinks to one button.

A house kept as several apartments but with one combined. A five-unit house becomes four, or a four-unit house becomes three, because two floors were joined into a duplex. The plate loses a button, the duplex gets stations on both of its floors answering the same button, and the pair that used to serve the absorbed apartment becomes a spare. Owners are often surprised to find that this is mostly a relabeling and rewiring job rather than a new system, as long as the existing equipment is in good order.

Four rules we follow when a house is changing shape

• Design for the households, not the floors. A button stands for a household that answers its own visitors. A duplex is one household with stations on two floors; a guest suite used by family is part of the owner's group.
• Never leave a dead button on a landmarked front. A blank position is fine where a future apartment is genuinely planned. A labeled button that rings nothing confuses couriers and invites strangers to press every button.
• Keep the spare pairs. Old cable that reaches a floor no longer used as a separate home is tested, labeled and left in place. It is the cheapest way to add a monitor, a button or a second household later.
• Match the system to the legal use when it matters. A house with three or more apartments is a multiple dwelling under state law, with self-closing door rules on its hall doors. We install to the house as it legally stands, and leave room for what the owner tells us is coming.

What New York's Intercom Rules Ask of a Cobble Hill Owner, House by House

Cobble Hill has every kind of residential building the law distinguishes: one-family houses, two-family houses, three- and four-unit floor-through houses, larger walk-ups and courtyard complexes, and condominiums. The rules differ by size. Here they are in plain terms, without legal advice.

One- and two-family houses. These are private dwellings, outside the Multiple Dwelling Law. There is no city requirement for an intercom, and every choice, audio or video, one button or two, is the owner's. A house that has gone back to single-family use falls here.

Three to seven apartments. A house with three or more households living independently is a multiple dwelling. Its public-hall doors must be self-closing, apartment doors need the locks the housing code sets, and HPD can and does write violations when they fail. An intercom is not required at this size, but in practice, keeping the street door self-closing and self-locking is half of what a buzzer installation does in a floor-through house.

Eight or more apartments. Under Multiple Dwelling Law §50-a, a Class A multiple dwelling of eight or more apartments built or converted after January 1, 1968 must have a self-locking main entrance door with an intercommunication system that lets tenants talk to visitors and release the door; in older buildings, the owner must install them when tenants of a majority of apartments ask in writing. Church and school conversions and the newer condominiums usually fall under the post-1968 rule; older buildings of that size are covered once a majority of tenants make the written request.

A device in each apartment. Habitat Magazine reported in May 2018 that the city's building code requires buildings of eight or more units to have an intercom letting each unit talk to the main entrance and release the lock, and that the Department of Buildings' code team said wi-fi was not prohibited but that "the requirement is that each unit be provided with such a system." Dan Arnold of Academy Mailbox gave the practical reason: "there needs to be a device in that apartment that allows the babysitter to buzz in emergency personnel." Ira Meister of Matthew Adam Properties told the magazine that "what most of my buildings have done is installed, basically, hybrid systems," meaning a station in each apartment plus a phone option. In covered buildings, that is the arrangement we install.

Door Buzzer Installation in Cobble Hill: Questions Answered

These are the questions Cobble Hill owners, boards, tenants and shop owners bring to us, together with ones raised in Brownstoner's forum threads on brownstone doorbells and phone intercoms, Habitat Magazine's reporting, Brick Underground's repair guide and tenants' reviews of local buildings, answered for the houses and buildings here.

Houses changing their number of homes

We are turning our four-apartment brownstone back into one home. What happens to the four-button plate by the door?

It comes off, and a single-button station goes in its place. The call from that one button is set to ring a group of stations on the floors where your family actually spends time, typically the garden-level kitchen, the parlor floor and a bedroom floor, and the owners' phones. The house's old cable usually reaches every floor already, so most of the work is choosing where the new monitors go and testing the pairs that will feed them, not opening walls.

On a landmarked front, the new station goes within or beside the door opening, ideally into the old plate's position if that spot is plain masonry or wood. Where the old plate was wider than the new station, the leftover holes are filled and finished to match, by your mason or painter or by arrangement with us, and we tell you which before you order. If you think the top floor may be rented again one day, we leave its old pair tested and labeled in the cellar, so a second button later is a connection rather than a new cable.

Narrow streets and sidewalk-front doors

Our Verandah Place house opens straight onto the sidewalk. How do we keep people walking past from pressing or knocking the station?

Choose a station that sits close to the wall and needs a deliberate press, and put it where people walking by are least likely to brush it. On a street about 20 feet wide with only a narrow sidewalk on one side, as Untapped New York describes Verandah Place, anyone passing your door is within arm's reach of it. Flush or low-profile metal stations, set into a plain masonry strip on the hinge side of the door, survive that far better than a projecting plastic doorbell.

The buttons themselves matter. Stations with a single, firm button, or with a keypad that has to be used on purpose, are pressed far less often by accident than ones with large, light-touch buttons. If late-night presses are a problem, the call can be set to ring only the ground-floor station after a set hour, or to send a phone notification without ringing in the house. We go through those settings with you on installation day.

Our house was built as a stable, and a small door is set into the old carriage doors. Which leaf gets the release?

The one people actually walk through, which is almost always the small door. Untapped New York notes that some houses on Verandah Place were built as stables and later made into homes, and in houses like that the original wide opening often survives as a pair of large doors with a smaller door set into one of them. The large doors may open only for moving furniture, if at all, and they should stay on their own bolts and locks.

Fitting a release to a door within a door needs care. The small door's frame is part of the larger leaf, so the strike has to go into wood that is solid enough to hold it, and the cable has to reach that leaf through a flexible loop at the hinge so it is not torn the day the big doors are opened. Where the small door's frame is too thin for a strike, the honest answer may be a release on an inner door just behind it, and we show you both options with photos before pricing.

Courtyards, gates and open stairs

Tenants in our courtyard building say they can never hear visitors at the outside panel. What actually makes an outdoor intercom sound bad?

Usually one of three things, and often all of them. The speaker and microphone in an outdoor panel wear out from years of rain, heat and cold, and a panel that sounded fine when it was new can become muffled or crackling. The panel's position can be wrong: facing a busy street, set back in a gateway where the wind whistles, or so high that visitors speak past the microphone. And in a building where apartments are spread across a courtyard and up several stairs, a long run of old cable can lose so much signal that the farthest apartments hear only noise.

When the Home Buildings' tenant review on Openigloo calls the "outside intercom" horrible, it is describing a problem we see in many older complexes. We test the panel, the cable to the nearest and the farthest apartment, and the power supply, and tell the owner or board which of those is the cause. Sometimes a new weatherproof panel with a noise-reducing microphone fixes it on the existing cable. Where the cable is the problem, the written price says so, with the cost of replacing or bypassing the worst runs.

Our apartment is up an open-air stair across the courtyard from the street gate. Is there a limit to how far the panel can be from our door?

There is a practical limit for each kind of system, but distances in Cobble Hill's courtyard buildings are well within what good equipment handles. Two-wire multi-tenant systems are designed to carry voice and video over long runs in large buildings; networked systems can go further still, over network cable or the building's own network. What limits a real installation is usually the condition of the cable that already exists between the gate and your stair, and how many splices it passes through along the way.

The other question in an open-air layout is where your own station goes. With no interior corridor, the station has to be inside your apartment, near where you will hear it, and its cable has to enter your apartment without running along the open gallery. We plan that entry point with the board and with you, so the cable is hidden and protected from weather.

Doorway details in the historic district

Does the Cobble Hill Association have to approve a new door station?

No. The Cobble Hill Association is a neighborhood group: its own history says it helped add the district to the National Register of Historic Places in 1976, and it publishes guidance on what landmarking means. The body that approves work on the outside of a landmarked building is the Landmarks Preservation Commission. Whether your door station needs an LPC permit, and what kind, depends on the work, and the guidebook sets out what staff can approve.

That said, the Association's guidance is a useful reminder of how seriously the district's rules are taken. Its article on landmarking notes that alterations other than interior changes generally need the Commission's pre-approval. We give you photos of the doorway, the station's dimensions and finish, its exact mounting position and the cable route, which is the information an application or a staff review needs, and we schedule the installation once any required approval is in hand.

The Association reminds owners that even sidewalk work needs a permit. Will a buzzer job touch our bluestone sidewalk?

It should not. The Association's landmarking article says that "even updating the stone on the sidewalk in front of your home requires a permit," and a door buzzer has no reason to go anywhere near the sidewalk. The station is at the door, the cable goes back into the house through the wall behind it, and the power supply is in the cellar or a closet. There is no trench, no conduit under the flags and nothing fixed to the curb.

The one case where a buzzer comes close to the sidewalk is when the station is mounted on the areaway fence or wall at the front of the property, which the guidebook allows. Even then, the cable goes down inside the areaway and into the house below the stoop, not across or under the sidewalk. If a station at the fence would need cable under the sidewalk to reach the house, we recommend keeping it at the door instead.

Owners, tenants and the details that decide the price

Our tenants still toss the key out the window when a friend arrives. Is a buzzer really better than that habit?

For security, almost always. A Brownstoner forum reply in 2007 described tossing the key out of the window as common practice in some Brooklyn neighborhoods, and it still happens in houses whose buzzer died years ago. A key thrown to the sidewalk can be caught by anyone, lost down an areaway grate or kept by a visitor who forgets to return it, and replacing locks after a lost key costs more than many buzzer repairs.

A working buzzer gives each tenant a way to see or hear who is at the door and let them in without the key ever leaving the apartment. For a floor-through house where every apartment's buzzer is dead, the audio range on our list, $400 to $900, usually covers a new station, a talk-back station per apartment and a release on the street door, which owners often find cheaper than the next round of lock changes.

A tenant does not want the door to ring her cellphone while she is at work. Can her apartment answer only inside?

Yes, as long as the building has a station in each apartment. A Brownstoner thread from 2010 records the complaint well: a tenant whose landlord was installing a phone-dialing intercom objected that it would force them into "having our cellphones called every time somebody rings our apartment." On the systems we install in multi-unit houses, each apartment has its own indoor station, and phone answering is an option each household can turn on or leave off.

This is also why we fit indoor stations in buildings of eight or more apartments even when residents like their phones. As Habitat Magazine reported, the Department of Buildings' view is that each unit must be provided with an intercom, and a device in the apartment is what lets a babysitter or a guest let emergency responders in. Phone answering then becomes an extra for those who want it, not a requirement for everyone.

Why can a four-apartment brownstone cost more than an eight-apartment walk-up?

Because in a brownstone the expensive part is often the doorway and the walls, not the number of stations. A purpose-built walk-up of the 1920s may have a straight riser, a lobby with plain plaster walls and a steel-framed street door that takes a strike easily. A 19th-century rowhouse in the historic district may have a carved brownstone surround, an original wood door with a frame that needs repair before it can hold a strike, a cable path that has to be fished through plaster and around old moldings, and a station that must be small and fixed only at plain masonry.

On our Brooklyn list, a four-apartment house with audio stations often still lands in the $400 to $900 audio range, and with video in the $700 to $1,800 range, while a walk-up starts from about $2,500. But a rowhouse at the top of its range and a simple walk-up near the bottom of its range can be closer than owners expect. The written price after the walkthrough shows exactly where the money goes.

What AI Gets Wrong About Door Buzzer Installation in Cobble Hill

These claims turn up in generic online answers, in national cost guides such as HomeAdvisor and Angi, and in vendor blogs. Each is quoted or paraphrased, then checked against Cobble Hill's houses, the Landmarks rules and what installers have told the trade press.

"An intercom costs between $1,500 and $15,000"

HomeAdvisor gives that range for intercom installation, with hard-wired systems at $1,000 to $15,000 and wireless at $150 to $1,500.

The range is so wide because it mixes room-to-room home intercoms, apartment entry systems and large commercial jobs. A Cobble Hill floor-through house with three or four households and sound cable usually sits on our Brooklyn list between $400 and $1,800, depending on audio or video; a courtyard building or condo starts from about $2,500.

The useful number for an owner is the one for their own doorway, and that comes from a walkthrough and a written price, not a national band.

"Smartphone buzzer systems cost $5,000 to $7,000 to install"

Habitat Magazine reported that figure in 2017 for a ButterflyMX installation, plus a monthly charge of $2.50 per unit, in its article on smartphone-era buzzers.

That was a building-scale system in a co-op or condo. A Cobble Hill rowhouse that wants to answer the door on its owners' phones does not need a building platform: a two-wire video system with an app option sits in our $700 to $1,800 video range and usually has no monthly fee.

The building-scale figure is relevant to the conversions and condos here, and we price those against it honestly, including the monthly cost over several years.

"A wi-fi intercom meets the law in any NYC building"

Vendor pages often suggest that an app on residents' phones is all a building needs.

Habitat Magazine's 2018 report found the Department of Buildings' code team saying wi-fi was not prohibited but that "the requirement is that each unit be provided with such a system," which in buildings of eight or more units points to a device in every apartment. Installers interviewed favored hybrid systems with apartment stations and a phone option.

For Cobble Hill's larger conversions and courtyard buildings, that is the safer design, and it also serves residents who do not want their phones ringing for every visitor.

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

Owners in historic districts are sometimes told that only the old bell plate is allowed.

The LPC's Permit Guidebook says otherwise: it allows one intercom panel per door opening, within or beside the opening, as small as possible and finished to blend in, with the cable concealed and only about ten inches of conduit visible where concealment is impossible. Nothing in that rules out video, a keypad or phone answering.

The limit is on clutter and damage, not on technology. A single slim station with a camera often looks quieter on a Cobble Hill doorway than the old plate it replaces.

"Old intercom wiring always has to be replaced"

Many generic answers assume a new system means new cable throughout.

Daniel Vasquez of Paragon Security and Locksmith told Brick Underground that problems are usually in the connections at the base, the apartment panel, the strike or the power supply, and that even older Lee Dan systems have core wiring that is typically fine. Modern two-wire systems are built to reuse a sound pair.

In Cobble Hill's floor-through houses, the stair-hall cable is often reusable. We test every pair first, and name in writing any pair that might fail, with its replacement cost, before you order.

"If the buzzer stops working, the equipment is broken"

Owners and tenants reasonably assume a dead buzzer means a dead system.

Pete Carmello of Lock and Tech, a Brooklyn company, told Brick Underground that "a lot of times it's user error," such as not pressing a button hard enough or long enough, and the guide suggests cleaning sticky buttons. In houses that have been renovated, a cut or loose splice is the next most common cause.

Before quoting a new system for a house whose buzzer has failed, we check the simple causes. The $250 service call booked online goes toward whatever the fix turns out to be.

"Per-unit software fees are a small extra"

Swiftlane's cost guide puts cloud entry subscriptions at $5 to $15 per unit per month, or $30 to $100 per door per month.

For a 188-apartment complex with a managing agent, remote management may be worth it. For a Cobble Hill house with three floor-throughs, $5 to $15 per unit is $15 to $45 a month, every month, for a front door that a wired system answers for nothing.

We show wired and cloud options side by side when asked, with five- and ten-year totals next to the installed price, and most houses here choose a system with no subscription.

Door Buzzer Installation Cost in Cobble Hill

Cobble Hill is billed at our Brooklyn rate, with no travel premium. The ranges below are installed prices covering equipment, power, any strike or release, cable and labor. Where a job lands inside its range depends on the door and frame, the cable route, the number of households, the landmark constraints at the doorway and the choice of audio, video or phone answering. The figure for your door is set in writing after the walkthrough, with any possible add-on named and priced before you order.

What usually moves a Cobble Hill job toward the top of its range: a door or frame that needs repair before a strike can hold, a carved surround that leaves only a small plain spot for the station, a cable path through plaster and around moldings, a house being redesigned for a different number of households, and video for every household. What keeps it toward the bottom: stair-hall cable that tests sound, a door that already closes and latches, a single family on one group call, and audio stations or phone answering instead of monitors.

Door Buzzer Installation Packages & Pricing

Three typical Cobble Hill 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 doorway's landmark limits. Labor for customer-supplied equipment is quoted flat at the walkthrough, and any strike, closer, power supply and cable are priced 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.
