Best New York Contractors for Apartment and Condo Remodels

Block Renovation is extremely selective about who makes it into its New York network, because these projects demand more than a good tile job or a clean set of cabinets. The contractors below know co-op boards, alteration agreements, freight elevators, old buildings, DOB filings, and the thousand little rules that come with renovating an apartment in this city.

All 10 bring extensive experience remodeling New York apartments and condos. But they also bring their own unique flavors and benefits. One can combine your apartment with the unit next door. One has its own warehouse for materials. Another builds cabinetry in-house because the walls in your prewar apartment probably stopped being square decades ago. Work with Block, and we can help you find the right contractor that meets your specific apartment remodeling needs. 

Knockout Renovation

More than a general contractor, Knockout Renovation is a design studio, retail showroom, and construction crew under one roof, and has been since 1992. Homeowners don't lose weeks bouncing between separate designers, suppliers, and contractors, because the people making the design decisions are working alongside the people responsible for getting the job built. Some of the finishes you're considering may even already be in Knockout's inventory.

Your project gets a designer who doubles as project manager, an office coordinator, and a lead carpenter. Their tradespeople specialize in co-ops and condos rather than jumping between apartment renovations and completely different kinds of construction. Knockout also talks openly about the parts of a New York renovation that make people nervous: alteration agreements, building rules, debris requirements, work-hour restrictions, and what the building architect expects to see before approving the plans.

Their work has appeared in the New York Times and on Queer Eye. And then there is the warranty: seven years covering both labor and products, transferable if you sell your NYC apartment or condo.  To see firsthand their remodeling work, look to this coop expansion and this multi-room transformation.

Metro Contractors

Metro Contractors deals with New York City apartment filings constantly. They know the difference between a project that stays relatively straightforward and one that pulls in additional DOB or Landmarks review, including the kind of approval that can add 4 to 12 weeks to the schedule. You want that conversation before construction planning gets too far along.

Their portfolio is almost entirely New York City apartments and condos, including:

• Prewar kitchens with marble counters and checkerboard tile floors
• Compact condo bathrooms with bold wallpaper and console sinks
• Galley kitchens opened up with long islands and floor-to-ceiling glass
• Exposed-brick loft living rooms in converted buildings

You also get a dedicated project manager, and Metro uses its own craftspeople on the job. The crew in your apartment isn't whoever happened to be free that week.

Art Deco Enterprises

One Brooklyn co-op owner had already spent more than a year out of her apartment after a flood when her renovation ran into another obstacle: a management company that kept pushing back on the approval package. Thankfully, she had Art Deco Enterprises in her corner to help mediate the process until the plans were approved, then purchased her bathroom materials and stored them in its own warehouse until the building was ready.

That is a very "New York apartment" kind of service not every contractor would offer.

A board delay is frustrating enough. It gets worse when boxes of tile, fixtures, and cabinetry have already arrived and there is nowhere legal or practical to put them.

Art Deco brings the same problem-solving instinct to the smaller design decisions. On a Queens condo, opening the kitchen to the dining room left no natural place for a conventional range hood. The team specified a downdraft unit that rises while you're cooking and disappears when you're done. They also mixed a custom paint color specifically for the apartment.

Why do share all this? Because Art Deco brings both the aesthetic taste and logistical talent to help any New Yorker elevate their apartment or condo. 

Ion Dodu and Sorina Panfil founded Art Deco in 2012. Ion started in construction at 16 and brought the trade to the US in 2007. Sorina developed her industry knowledge through her family's engineering background while pursuing a master's in business, and today she runs the client side of the company. 

Designs by D & J

Designs by D & J is built for the projects that make plenty of contractors hesitate: combining neighboring apartments, working inside landmarked buildings, preserving complicated prewar layouts, and managing large gut renovations across multiple floors.

Jay and Dominique own the company and stay involved in the jobs themselves. The people you meet during planning don't vanish once construction starts. D & J is MWBE-certified and licensed in New York and New Jersey, and the company publishes its license numbers, change-order policy, and weekly check-in schedule before you sign. Homeowners also receive a written one-year workmanship warranty, a close-out package, and final DOB sign-off when the scope requires it.

I&N Builders

I&N Builders redefines what it means to be "transparent." Case in point, during an Upper West Side apartment renovation, the electrician uncovered wiring that wasn't up to code. The homeowners heard about it immediately, along with what fixing it would involve: coordination with the building and DOB involvement. I&N Builders' careful coordination meant that the hiccup was addressed without major drama, helping thwart what could have been every New Yorker's renovation nightmare. 

Combining New York apartments is another I&N remodeling specialty. A Murray Hill project joined two side-by-side units into one open home with skyline views, with the kitchen, bathroom, foyer, laundry, and circulation reconsidered as one larger plan.

Nina and Ilya run the New York company as a husband-and-wife team that merges her creative eye with his construction prowess. While they work on properties of all types, their portfolio is rich with New York townhouses, apartments, and condos. The Block team hears the same consistent feedback from our customers: I&N Builders are incredibly collaborative, making homeowners feel both heard and taken care of. 

JC Construction NY Corp

JC Construction NY Corp gets work through superintendent referrals, and that's one of the strongest endorsements a New York apartment contractor can earn. Supers see what happens before the finished photos: whether crews protect the hallways, follow delivery rules, show up when promised, clean up properly, and make the building staff's life harder or easier.

JC's portfolio shows it's not afraid of some "heavy lifting". During a full Manhattan apartment renovation, Jairo Segura's crew removed partition walls, skim-coated the surfaces, replaced the tub with a shower, recessed the television, installed new interior doors, and built custom cabinetry and heater covers for the dining area.

Those heater and convector covers are exactly the sort of thing lesser renovation portfolios usually skip. Similarly, on another apartment project, the team lowered the kitchen floor so it finally sat level with the rest of the apartment.

In short, JC Construction NY Corp is strong choice for New York renovations that involve gutting or major structural changes, especially if they are in shared apartment buildings. 

Supreme Renovation A2Z

Supreme Renovation A2Z has its own woodworking shop, and that matters in a New York prewar apartment. Stock cabinetry assumes straight walls and clean corners. New York apartments frequently provide neither.

This Upper West Side kitchen shows what in-house millwork makes possible: wood veneer cabinetry, white lacquer uppers, a waterfall quartz island, full-height stone backsplash panels, and a ventilation enclosure incorporated into the cabinetry so the hood doesn't interrupt the line of the kitchen.

Aslam and Mike take homeowners from the initial consultation and 3D visualizations through materials, permitting, and the final walkthrough, with filings handled in-house. The same woodworking shop also produces custom wood stairs built to DOB code, typically installed in a day.

M Construction NY Corp

M Construction NY Corp spends most of its time exactly where many apartment owners want their contractor to have experience: Manhattan.

Central Park West, Fifth Avenue, Sutton Place South, Columbus Circle, Lincoln Square, Riverside, and Tribeca all appear in the company's portfolio. If you're renovating a prewar co-op, that concentration matters. The team has already worked inside older Manhattan buildings and understands the kind of questions boards and building managers tend to ask before approving construction.

The Line Construction

You don't always have the luxury of moving out while your apartment is renovated. The Line Construction is accustomed to working in homes where the owners are still living.

That changes how a renovation gets planned. The family-run team can phase the work so you aren't unnecessarily giving up the whole apartment at once, including separating a larger project into stages, such as renovating the kitchen this year and tackling the bathrooms next.

But convenience isn't the only reason to partner with The Line Construction; their portfolio is full of beautiful New York apartment and condo transformations. They bring functionality and craftsmanship to smaller spaces like this Brooklyn bathroom and one-wall kitchen. The results feel custom without alienatinng future buyers or renters. 

BH Interiors

BH Interiors is the New York general contractor on this list to notice when your project has a lot of moving parts.

One renovation ran for 40 weeks and covered five bathrooms, five bedrooms, a kitchen, two living spaces, a foyer, laundry, a garage, roofing, and exterior work. Keeping that many trades in sequence for that long takes serious scheduling discipline. Put the same challenge inside a New York apartment building, where everyone is sharing loading areas, service entrances, and freight elevator windows, and that experience becomes even more useful.

BH has worked across New York and Connecticut since 2007, with much of its work concentrated in Manhattan and Westchester County. 

Why experience in buildings like yours matters

A contractor can be excellent at renovation work and still be the wrong contractor for your specific New York building. A prewar co-op, a newer high-rise condo, a landmarked brownstone, and an occupied walk-up all create different problems before anyone gets to the actual construction. Experience with structures like yours gives the contractor a head start on the parts that can otherwise eat into the schedule.

• They know how the approval process works. Co-op boards, condo associations, building architects, and management companies can all ask for different drawings, insurance documents, licenses, deposits, and alteration agreements. A contractor familiar with similar buildings is less likely to discover a missing requirement after you've already submitted the package.
• They understand how work actually gets into the apartment. Freight elevator reservations, loading dock hours, hallway protection, delivery windows, and limits on where materials can be stored can dictate the pace of a renovation. In a walk-up, the problem may be getting a bathtub around the landing turn instead.
• They've seen the building systems before. Prewar apartments can mean old electrical wiring, steam radiators, uneven floors, plaster walls, and plumbing shared vertically with other units. Newer high-rises bring their own systems and building rules. Familiarity helps your contractor know what to investigate before the walls are open.
• They know what your neighbors and super will care about. Noise hours, debris removal, elevator cleanup, water shutoffs, and keeping common spaces protected sound minor until one of them stops work for the day. Contractors who regularly work in occupied apartment buildings already understand that construction extends beyond your front door.
• They can plan around the physical limits of the building. A 10-foot kitchen island is only useful if its countertop can make it upstairs. Large-format stone, oversized vanities, long cabinetry runs, and shower glass all need a path from the street to the room where they'll be installed.
• They start with fewer unknowns. Nobody can predict everything hiding behind the walls, but a contractor who has renovated apartments of the same age, construction type, and building style has a much better idea of what deserves a closer look before the budget and schedule are locked in.

Find your apartment or condo contractor with Block Renovation

These 10 contractors are only part of Block's New York network, and that's exactly the point. The contractor who is fantastic at combining apartments isn't automatically the contractor you need for a smaller occupied renovation, just as the millwork-heavy prewar specialist isn't necessarily the right match for every condo.

Tell Block about your building, scope, and timeline once. From there, you're matched with vetted contractors whose experience actually fits the apartment or condo renovation you're planning.
