Pre-war townhouses in the Bronx present a specific set of challenges: aging drain stacks, corroded supply lines, outdated wiring, and brick facades subject to moisture infiltration and aging mortar deterioration. We handle townhouse renovation in the Bronx from foundation to roofline, coordinating NYC Department of Buildings permits, structural work, mechanical upgrades, and finish trades under our direct supervision. Our team is licensed and insured, and we have worked through the full range of pre-war building conditions across the borough.

A full Bronx townhouse remodel is not a single-trade job. Neighborhoods like Fordham and Kingsbridge carry dense pre-war construction stock, and behind those plaster walls you typically find aging cast iron drain lines, knob-and-tube or cloth wiring, and undersized electrical panels that were never designed for modern loads. Cast iron stacks in these buildings corrode from the inside out, developing pinhole leaks and partial collapses that only show up once a wall is opened. Cloth-insulated conductors become brittle and lose their sheathing, creating fault risk that no longer meets NEC or NYC code. A multi-story renovation means coordinating plumbing risers across every floor, running new 200-amp service, and often removing or reinforcing load-bearing walls between the parlor floor and the lower level.
Every structural change, plumbing alteration, and electrical upgrade in a townhouse gut renovation triggers DOB filing requirements. Whether your project files as an Alt-1 or Alt-2 depends on whether the certificate of occupancy changes. A Class A multiple dwelling filing differs from a Class B or single-family filing, and that classification drives which forms, inspections, and professional certifications apply. We hold a Home Improvement Contractor License (#2113624-DCA) and handle all applications, inspections, and sign-offs directly. Our general contracting approach keeps permit coordination and trade scheduling managed end to end. For landmarked properties, we coordinate the Landmarks Preservation Commission review layer before any permit is filed.
Our crew handles demo, carpentry, tile and finishes; licensed plumbers and electricians handle regulated work under our direct supervision. Our team files directly with the DOB, coordinates licensed trades, and manages structural, mechanical, and finish work from demolition through final inspection. Here is what a full-scope project typically covers:
Full gut renovations in the Bronx typically run in the low-to-mid five figures per floor, with pre-war buildings landing at the higher end once mechanical replacement and structural work are factored in. A kitchen-and-two-bath scope in a pre-war townhouse runs very differently than a top-to-bottom gut across four stories, so no honest number exists without a walkthrough. Timelines follow the same logic: a full multi-story gut renovation usually runs 4 to 6 months from permit approval to final sign-off, while a partial renovation covering a kitchen and two baths can close out in 6 to 10 weeks. Buildings with corroded stacks and brittle wiring almost always need more time than the structure alone suggests.
Whatever the scope, we pull every required permit and coordinate every trade under our direct supervision. That includes kitchen remodeling, bathroom renovation, flooring, electrical, and plumbing, all under our direct supervision.
We evaluate existing load-bearing walls, file DOB alteration permits, and remove or reinforce structure to open floor plans across all stories. Every modification is engineered and inspected before finish work begins.
We strip the kitchen to the studs, reroute plumbing and gas lines as needed, and rebuild with new cabinetry, countertops, and appliances. See our full scope for kitchen remodeling.
Every bathroom gets a full gut renovation: new tile, fixtures, vanities, and code-compliant ventilation. Details on our approach to bathroom renovation apply to every floor of your townhouse.
We replace cloth wiring and undersized panels, bringing the home up to NYC electrical code with all required permits filed.
We replace deteriorated cast iron stacks and galvanized supply lines with new copper or PEX throughout. Our plumbing services cover full stack replacement and fixture installation on every level.
We install hardwood, engineered wood, and porcelain tile across all floors, matching existing millwork and handling transitions between stories. Full details on materials and methods are on our flooring installation page.

Every townhouse gut renovation in the Bronx follows the same four-step sequence. We run it that way because pre-war buildings rarely reveal all their conditions until someone walks every floor with a trained eye. Skipping steps early creates problems at inspection later.
We start at the top floor and work down. We check structural conditions, map existing drain stacks and supply lines, identify brittle wiring or undersized panels, and document what each floor needs before we write a single line of scope. Nothing gets estimated from photos or phone calls.
Once scope is defined, we file the appropriate DOB alteration applications. Structural, plumbing, and electrical changes each carry their own filing requirements, typically Alt-2 or Alt-1 depending on scope. For properties in landmarked zones, we coordinate the Landmarks Preservation Commission review before permits are issued. We build the project schedule around inspection windows from day one.
Demolition, load-bearing wall work, framing, plumbing services, and electrical services all run in sequence under our direct supervision. A single point of contact coordinates every trade on every floor. For a full picture of how we handle home renovation across property types, that page covers our broader approach.
Finish work moves floor by floor: tile, cabinetry, flooring, painting, and trim. Inspections are scheduled as each phase closes out. We work to ensure the property is fully compliant at handover, with violations resolved and sign-offs completed.
Pre-war townhouses give clear warning signs before small problems become structural ones. Knowing what to look for tells you whether you need spot repairs or a full multi-story renovation.
Step on a soft spot and feel the floor flex underfoot. That deflection usually means deteriorated subfloor sheathing or compromised joists, not just worn finish. Left alone, the damage spreads to adjacent bays. Our team handles flooring installation that addresses the structural layer first, not just the surface.
Gurgling from two or three floors at the same time is not a clog. It points to a corroded or partially collapsed cast iron stack, common in older pre-war townhouses. Our plumbing services cover full stack replacement before a failure forces emergency work.
A panel that cannot hold load or dead outlets throughout the house signal cloth wiring or undersized service. Neither meets current NYC electrical code. Our team provides electrical services that bring the full system up to code.
Diagonal cracks at window corners or long horizontal lines along ceiling planes in plaster-over-lath construction indicate settling, moisture intrusion, or structural movement. Cosmetic patching over active cracks fails fast. Evaluation comes before any finished work.
Galvanized supply lines, missing GFCI outlets near sinks, and layouts that predate modern code are not cosmetic problems. They are code deficiencies. A townhouse remodel corrects these at the source, not around them.
The Bronx has significant pre-war attached and semi-detached townhouse stock. Much of the borough's housing stock is older, which means cast iron drain stacks, galvanized supply lines, brittle wiring, plaster-over-lath walls, and undersized panels are common. These buildings were never designed to carry modern mechanical systems, and that gap shapes every renovation decision from day one.
Moisture infiltration is a persistent issue in pre-war Bronx townhouses. Aging mortar joints allow water to work into party walls and floor assemblies over time. Uninsulated attic spaces allow moisture to migrate into top-floor ceilings. Waterproofing, facade pointing, and insulation upgrades are not optional add-ons here. They are standard scope items that protect everything else you invest in.
The regulatory layer adds another dimension. Any permit that touches structure, plumbing, or electrical requires formal filings, and the classification of the building as a Class A multiple dwelling versus a single-family Class B home changes what forms and certifications apply. Portions of the borough's historic corridors fall under Landmarks Preservation Commission jurisdiction, which means LPC review comes before permits are issued. The gap between what an owner considers cosmetic and what the city classifies as an alteration requiring a licensed architect or engineer is not always obvious. We manage that regulatory layer directly, including local law compliance requirements that catch many owners off guard.
Our team has worked across all five boroughs for 22+ years, handling pre-war buildings that most contractors will not touch. That track record shows in our 100+ five-star Google reviews, where clients consistently cite promptness, quality, and professionalism on complex jobs. You can read the full story on our about page.
Structural, electrical, plumbing, tile, flooring, and painting are all managed under our direct supervision and a single Home Improvement Contractor License. Licensed plumbers and electricians handle regulated work under our direct supervision. This coordination helps prevent gaps that stall your project mid-renovation.

Yes. Any structural alteration, plumbing modification, or electrical upgrade in a Bronx townhouse requires NYC Department of Buildings permits. Cosmetic work like painting or flooring typically does not, but the gap between what counts as cosmetic and what triggers a permit is not always obvious. Unpermitted structural or mechanical work creates real liability at resale and can result in violations that stop a sale cold. Our team files all required applications and manages inspections from start to finish. See our local law compliance contractor page for more detail on how this process works.
A full gut renovation of a multi-story Bronx townhouse typically runs 4 to 6 months from permit approval to final sign-off. Scope and existing system condition drive that range. Pre-war buildings with corroded drain stacks, galvanized supply lines, and brittle wiring almost always require more time than the structure alone suggests. Partial renovations covering a kitchen and two baths can be completed in 6 to 10 weeks. Permit timelines vary and are factored into your project schedule from day one.
Yes. Our team handles structural, tile, flooring, and painting, while the licensed plumbers and electricians we coordinate handle regulated work under a single contract. That matters on a multi-story townhouse renovation because the coordination gap between separate subcontractors is where delays and cost overruns happen. One point of accountability means no finger-pointing when trades overlap. For a full picture of what that covers, see our home renovation service page.
Parts of the Bronx fall under Landmarks Preservation Commission jurisdiction, which adds a review layer before permits can be issued. Work on the exterior envelope, windows, or facade of a landmarked townhouse requires LPC approval first. We identify these requirements during the initial on-site assessment and coordinate the filing process directly. Our team serving as your general contractor means those regulatory layers get handled before they become schedule problems.
Townhouse renovation costs vary widely based on scope, building condition, and the extent of mechanical system replacement. Full gut renovations tend to land in the low-to-mid five figures per floor, and a kitchen-and-bath renovation in a pre-war townhouse runs very differently than a full gut across four stories. You receive a firm, itemized estimate before any work begins, so you know exactly what the project covers before a contract is signed.
