NYS and NYC M/WBE Certified Contractor
Most homeowners in New York City don’t struggle with picking tile or choosing a vanity. The hard part is everything that happens before a single tool touches the wall. Alteration agreements, DOB filings, board-approved insurance certificates, licensed master plumbers the regulatory layer alone stops a lot of projects before they start. When you work with a contractor who already knows this process, that layer stops being a barrier and starts being a box you check on the way to a finished bathroom.
New York City’s housing stock is the third oldest in the country. That matters the moment demo begins. Behind the tile in a pre-war Manhattan co-op or a Brooklyn brownstone, you might find galvanized pipes that have been corroding since the 1940s, asbestos-containing adhesive under the floor, or moisture damage that’s been quietly spreading for decades. Most bathroom remodelers stop work and start making calls. We handle it in-house remediation, abatement, restoration without halting your project or sending you scrambling for a second contractor.
The end result isn’t just a renovated bathroom. It’s a permitted, board-approved, fully documented renovation that protects your apartment’s value in one of the most competitive real estate markets in the world. With New York City’s median residential property price sitting around $735,000, that documentation matters as much as the tile work.
We’re a Long Island-based remodeling and environmental restoration company that has been working throughout New York City including Manhattan, Brooklyn, Queens, and the Bronx long enough to know that no two buildings here are the same. A Park Avenue co-op has different board requirements than a Williamsburg condo. A pre-war building on the Upper West Side has different plumbing realities than a postwar mid-rise in Astoria. That depth of experience is what makes the difference between a project that moves and one that stalls.
We handle everything under one roof: demolition, plumbing coordination, electrical, waterproofing, tile, fixture installation, and cleanup. That also includes asbestos abatement and mold remediation capabilities that aren’t common in bathroom remodeling companies, but are genuinely necessary in a city where the average building is pushing 80 years old. You get one point of contact, one accountable team, and a finished bathroom that was done the right way from start to finish.
It starts with a detailed site assessment. Before any plans are drawn or materials ordered, we evaluate your space, your building’s specific requirements, and what’s likely behind your walls based on the building’s age and construction type. In New York City, this step is more involved than in most places your building’s alteration agreement may restrict what plumbing changes are possible, and the DOB’s ALT2 permit process requires a licensed architect or engineer before any work can be filed. That coordination starts here, not after demo has already begun.
Once the scope is confirmed and your building’s documentation requirements are met insurance certificates, board application materials, contractor qualifications work begins within the hours your building allows. Most New York City co-op and condo buildings restrict construction to weekdays between 9 a.m. and 5 p.m., no weekends. That compressed window means every day on-site counts. Our crew shows up on time, works the full window, and doesn’t leave you with an open bathroom and a vague timeline.
If demo reveals anything unexpected and in a pre-war building, it often does we address it directly rather than pausing the project. Asbestos, deteriorated plumbing, mold behind the tile: these get handled in-house, documented properly, and resolved before the new work goes in. The final walkthrough includes a full review of completed work, all permit documentation, and anything your building’s management office needs for their records.

A bathroom renovation in New York City isn’t just a construction project it’s a coordination project. We manage the full scope: demolition, waterproofing, plumbing, electrical, custom tile work, vanity and fixture installation, and final cleanup. But what separates this from a standard remodel is the layer of New York City-specific work that surrounds all of it. That means preparing your alteration agreement documentation, coordinating with a registered architect for DOB ALT2 permit filing, supplying the insurance certificates your co-op or condo board requires, and making sure every step of the project is compliant with your building’s specific rules.
For buildings in New York City’s 120-plus historic districts or any of the city’s 36,000-plus individually landmarked properties Landmarks Preservation Commission requirements may apply even for interior work. We account for that upfront, not mid-project. Waterproofing is treated as a non-negotiable in every job, because in a building where your bathroom sits above someone else’s living room, a moisture failure isn’t just your problem.
Bathroom remodel costs in New York City typically range from $18,000 to $74,000 or more depending on finish grade, plumbing complexity, and building-specific requirements. A targeted refresh without plumbing relocation starts lower; a full gut renovation with custom tile and high-end fixtures sits at the higher end. For gut renovations specifically, setting aside a 15 to 20 percent contingency is strongly recommended not because something will definitely go wrong, but because in a pre-war building, the odds of finding something behind the wall that needs attention are genuinely high.
In almost every case, yes. If your bathroom renovation in New York City involves any plumbing relocation, electrical upgrades, or changes to walls or building systems, the NYC Department of Buildings requires an ALT2 permit before work begins. That permit has to be filed by a licensed Registered Architect or Professional Engineer not the contractor directly. A licensed master plumber also needs to pull a separate plumbing permit for any plumbing work.
Skipping permits isn’t a gray area in New York City. Unpermitted work can trigger stop-work orders, fines, and real complications when you go to sell or refinance. It can also create liability if water intrusion from your bathroom affects a neighboring unit and in a building where your floor is someone else’s ceiling, that’s not a hypothetical. Working with a contractor who coordinates the permit process from the start protects you, your apartment, and your relationship with your building’s board.
Your building’s alteration agreement is the starting point. That document outlines exactly what your New York City co-op or condo board requires before approving any renovation specific insurance minimums the contractor must carry, a detailed scope of work, proof of contractor licensing, and often architectural plans stamped by a licensed professional. Some buildings also require a security deposit held against potential damage to common areas.
The most common reason board applications get delayed or rejected isn’t the renovation itself it’s incomplete documentation from the contractor. Insurance certificates that don’t meet the building’s specific minimums, scopes of work that are too vague, or contractors who aren’t familiar with the process all create friction that slows everything down. When your contractor has done this before and knows what New York City boards are looking for, the application process moves faster and with a lot less back-and-forth.
Pre-war buildings in Manhattan, Brooklyn, and the Bronx were constructed before most modern building codes existed, and many have been partially updated over the decades in inconsistent ways. When demo begins, the most common discoveries include galvanized iron pipes that have corroded significantly and reduced water pressure, original tile set in a thick mortar bed rather than cement board, cast iron drain lines that have shifted or cracked over time, and asbestos-containing materials in floor tile adhesive, pipe insulation, or plaster walls.
Moisture damage is also extremely common especially in bathrooms that were never properly waterproofed or that had slow leaks go undetected for years. None of these are worst-case scenarios. In buildings from the 1920s through 1940s, they’re routine. The key is working with a contractor who can handle them in-house rather than stopping the project to source a separate specialist. Our remediation background means asbestos abatement, mold remediation, and water damage restoration are handled by the same team doing the renovation no project halts, no second contractor, no second board approval for a new scope.
It depends on your building, and the answer is often more restrictive than homeowners expect. In most New York City apartment buildings, plumbing stacks run vertically through the structure, and horizontal movement of plumbing fixtures relocating a toilet across the room, moving a shower to the opposite wall is heavily restricted or outright prohibited by co-op boards. The reason is practical: significant horizontal plumbing runs require changes to the drain slope, which affects the stack that serves every unit above and below yours.
Some buildings do allow limited plumbing relocation with proper DOB filing and board approval, but it adds cost, time, and complexity to the project. Before you design a renovation around a layout change, it’s worth having a contractor who knows New York City’s building systems evaluate what’s actually feasible in your specific building. Designing a renovation that can’t be built is a frustrating and expensive mistake and it happens more often than it should when contractors aren’t familiar with how New York City buildings actually work.
For a full gut renovation in a New York City apartment, a realistic timeline is four to six weeks of active construction but the total project timeline from initial planning to finished bathroom is often longer when you factor in board approval, DOB permit filing, and material lead times. Board applications alone can take two to four weeks depending on the building’s review schedule. Permit filing with the NYC Department of Buildings adds additional time before work can legally begin.
Once construction starts, the compressed work window matters. Most New York City buildings restrict contractors to weekdays between 9 a.m. and 5 p.m. no weekends, no holidays. That’s roughly 40 hours per week of available work time, compared to the more flexible scheduling that’s possible in a single-family home. A contractor who shows up consistently and works the full window makes a real difference in whether a four-week project stays at four weeks or stretches to six. Unexpected discoveries during demo which are common in pre-war buildings can also extend the timeline, which is another reason to build a contingency into your budget and schedule from the start.
Bathroom remodel costs in New York City range from roughly $18,000 on the lower end for a straightforward refresh to $74,000 or more for a full gut renovation with high-end finishes. That wide range is driven by a few key factors: the grade of materials you choose, whether any plumbing is being relocated, how much prep work is needed after demo, and the building-specific requirements that add cost and time unique to New York City projects.
Permit filing, licensed master plumber fees, and architectural plans for DOB submissions are costs that don’t exist in suburban renovations they’re part of doing the job legally in New York City. If your building is in a historic district or is individually landmarked, Landmarks Preservation Commission compliance may add another layer. For gut renovations in pre-war buildings specifically, a 15 to 20 percent contingency on top of your base budget is a practical recommendation not a cushion for overspending, but a realistic acknowledgment that buildings from the 1920s and 1930s regularly reveal conditions behind the walls that need to be addressed before new work goes in.
