General Contractor in Brooklyn, NY — Home & Apartment Renovations

Comprehensive Renovation Services Across Brooklyn

Brooklyn’s housing stock includes over 100,000 buildings constructed before 1940, creating specific renovation requirements for structural systems, electrical, plumbing, and facade preservation. Our licensed team delivers complete solutions for residential properties across all neighborhoods.

Brownstone and Townhouse Renovation

Brooklyn contains the highest concentration of brownstone rowhouses in New York City. Our brownstone renovation services address sandstone facade restoration, parlor floor modernization, garden-level conversions, and multi-floor gut renovations. For limestone and brick townhouses, we handle rear extensions, cellar excavations, staircase restoration, and complete interior reconfigurations.

Kitchen Remodeling

Kitchen renovations are the most requested project across Brooklyn. We transform cramped galley kitchens in pre-war brownstones into open-concept layouts with custom cabinetry, stone countertops, and modern appliance integration. Brooklyn kitchens often require structural modifications — removing load-bearing walls with steel beam installation — and complete plumbing and electrical system upgrades.

Bathroom Renovation

Brooklyn bathroom renovations range from cosmetic updates in co-op apartments to full gut-and-rebuild projects in brownstones. We install walk-in showers with Kerdi or Hydroban waterproofing systems, heated flooring, modern vanities, and updated plumbing — with particular expertise in pre-war cast iron stack work and limited-space layouts.

Apartment and Co-op/Condo Renovation

Brooklyn’s co-op and condo buildings require alteration agreement management, board coordination, and compliance with building-mandated construction hours and insurance requirements. We handle the full apartment renovation process from board submission through final walkthrough.

Loft Renovation

Williamsburg, Bushwick, DUMBO, and Greenpoint feature converted industrial lofts with open floor plans, exposed brick, and high ceilings. We build out these spaces with custom partitions, mezzanine construction, kitchen and bathroom installations on concrete slabs, and mechanical system design for open-plan living.

Trade Services

We provide standalone plumbing, electrical, flooring, and painting services as part of larger renovations or as individual projects. Brooklyn’s pre-war housing stock frequently requires galvanized pipe replacement, panel upgrades from 60-amp to 200-amp service, hardwood floor refinishing, and plaster repair with skim coating.

The Brooklyn Building and Renovation Landscape

Brooklyn’s residential architecture consists primarily of rowhouses, brownstones, and mid-rise apartment buildings constructed between 1880 and 1960. Neighborhoods like Park Slope and Brooklyn Heights feature Italianate and Romanesque Revival brownstones with limestone and sandstone facades.

Bedford-Stuyvesant contains the largest concentration of intact Victorian-era housing stock in the United States, while Williamsburg and Bushwick showcase converted industrial lofts and newer condominium developments. Carroll Gardens and Cobble Hill feature smaller-scale rowhouses with private gardens, and and Bay Ridge, one of the first neighborhoods we worked in, mixes pre-war apartment buildings with single-family homes and semi-detached houses.

These varied building types require specialized approaches to structural modifications, facade restoration, and mechanical system upgrades that respect original construction methods while meeting current DOB code requirements.

Common Renovation Challenges in Brooklyn

Our experience with Brooklyn properties enables us to anticipate complications before they affect timelines or budgets:

Lead Paint and Asbestos: Properties built before 1978 constitute approximately 70% of Brooklyn’s housing stock, requiring EPA-certified remediation protocols during demolition and surface preparation. Our EPA certification (NAT-F277952-1) ensures compliant handling.

Galvanized Pipe Replacement: Brownstones and pre-war apartment buildings typically contain original galvanized steel plumbing that corrodes after 70+ years. Complete plumbing system replacement with copper or PEX supply lines is often necessary during gut renovations.

Knob-and-Tube Wiring: Homes constructed before 1940 often retain obsolete electrical systems lacking grounding conductors. Complete rewiring to meet current NEC standards is critical for safety and insurance compliance.

Material Access and Staging: Rowhouse construction without driveways or loading zones requires DOT parking permits and careful scheduling of material deliveries through narrow stoops and hallways. Landmark District Compliance: Properties in Brooklyn Heights, Park Slope, Fort Greene, Clinton Hill, Prospect Heights, Crown Heights North, and other designated districts require LPC approval for exterior modifications and certain interior work affecting historic fabric.

Renovation Costs in Brooklyn

Brooklyn renovation costs reflect the borough’s older housing stock, which often requires more extensive structural repairs and hazardous material abatement than newer construction. Here are general ranges:
Cosmetic Update (paint, fixtures, hardware): $10,000–$30,000
Kitchen Remodel: $25,000–$75,000+
Bathroom Renovation: $15,000–$50,000+
Single-Floor Brownstone Renovation: $75,000–$175,000
Full Brownstone Gut Renovation: $300–$500+ per square foot
Apartment Gut Renovation: $150–$350 per square foot
Brooklyn-specific cost factors include landmark district compliance costs, co-op board insurance minimums, limited staging areas that increase material delivery costs, and the prevalence of pre-war construction requiring hazardous material abatement.

Permits and Regulations in Brooklyn

The NYC Department of Buildings requires permits for structural modifications, plumbing alterations, and electrical upgrades. Co-op and condo boards maintain their own approval processes that often exceed DOB requirements — including alteration agreements, insurance certificates naming the building as additional insured, and neighbor notification letters. Properties within designated historic districts require Landmarks Preservation Commission approval for exterior work, which must precede DOB permit applications.

Our team manages the complete permit and approval process, including architectural drawings, engineering certifications, DOB filings, LPC applications, and board package preparation. Active general contractor license #626219 ensures compliance with all municipal regulations.

Neighborhoods We Serve in Brooklyn

Our crews work across Brooklyn’s most architecturally distinct neighborhoods, each with its own building stock, permitting requirements, and renovation priorities. For property managers and co-op boards, we serve as a single point of contact through every stage of a project, from initial scope development and DOB filings through trade coordination, inspection scheduling, and final sign-off.

Bay Ridge

One of the first neighborhoods we worked in, Bay Ridge is home to semi-detached brick houses, pre-war apartment buildings along Shore Road, and limestone rowhouses on the numbered avenues. We handle everything from kitchen gut renovations in Owners Corp co-ops to rear extensions on single-family homes throughout the 68th Precinct. For co-op boards in this neighborhood, we prepare complete alteration agreement packages, carry the required insurance certificates naming the corporation as additional insured, and manage DOB filings and inspections without requiring board members to track progress independently.

Park Slope

Our headquarters neighborhood, Park Slope’s Historic District contains one of the largest concentrations of intact Italianate and Romanesque Revival brownstones in the country, which means Landmarks Preservation Commission approval drives most renovation timelines. We specialize in parlor-floor restorations, garden-level conversions, and modernizing pre-war kitchens without disturbing original moldings, mantels, or stair detail. Because LPC review frequently precedes DOB filing, we build that sequencing into every project schedule from the outset, so delays at one agency do not catch owners or property managers off guard.

Williamsburg

Williamsburg blends converted industrial lofts along the waterfront with frame houses in the South Side and new condo construction throughout. We build out raw loft spaces with custom partitions and kitchens on concrete slabs, and handle ground-up interior work in the glass-and-steel condos that now line Kent Avenue. For condo management companies overseeing multiple units in the same building, we coordinate access, freight elevator reservations, and construction hours with building staff directly so the day-to-day operations of the property are not disrupted.

DUMBO

DUMBO’s warehouse conversions feature timber post-and-beam construction, 14-foot ceilings, and massive factory windows that constrain where plumbing and HVAC can run. Our team has experience designing mechanical systems that preserve original ceiling exposure while meeting current code, and we coordinate closely with building managers at Two Trees properties. When structural modifications require special inspection under a New York City Alt-1 filing, we engage the required special inspector, track inspection hold points, and ensure DOB sign-offs are obtained at each phase before proceeding.

Brooklyn Heights

As New York City’s first designated historic district, Brooklyn Heights requires LPC review for virtually all exterior work and much of the interior work in landmarked buildings. We renovate pre-war co-ops in buildings like One Grace Court and The Standish, along with Federal-style and Greek Revival townhouses on Willow, Cranberry, and Pineapple Streets. Our familiarity with the LPC application process, including Certificate of No Effect and Certificate of Appropriateness filings, allows us to give co-op boards and property managers an accurate timeline before a shovel goes in the ground.

Cobble Hill

Cobble Hill’s smaller-scale rowhouses, many under 20 feet wide, demand precise space planning and careful structural work. We handle full gut renovations, cellar excavations for added square footage, and rear-yard extensions that maximize the neighborhood’s compact lot configurations. Where a cellar underpinning requires an engineer of record and a special inspection program under the DOB’s technical standards, we manage those coordination requirements as part of our standard project delivery.

Carroll Gardens

Carroll Gardens is known for its deep front gardens and Italianate rowhouses, most built in the 1860s and 1870s. Our work here focuses on updating original cast iron plumbing, rewiring knob-and-tube electrical, and restoring sandstone stoops and cornices while preserving the neighborhood’s streetscape character. For owners navigating a DOB violation issued against aging plumbing or electrical systems, we assess the condition, scope the corrective work, and file the necessary work permits to resolve the violation through the Certificate of Correction process.

Greenpoint

Greenpoint combines frame and brick rowhouses from the shipbuilding era with new luxury towers along the East River. We handle structural repairs on 150-year-old workers’ cottages, loft buildouts in converted Manhattan Avenue warehouses, and high-end finish work in Greenpoint Landing and 2 North 6th Place. For property managers at larger residential buildings in the area, we provide progress documentation at each construction phase and coordinate with the building’s managing agent on scheduling, deliveries, and any required tenant notifications.

Prospect Heights

Prospect Heights’ Historic District covers brownstones and apartment buildings along Eastern Parkway, Plaza Street, and the side streets leading to Grand Army Plaza. We manage LPC-approved facade restorations, full-floor co-op renovations in pre-war buildings, and layout reconfigurations that open up original railroad-style apartments. Because many buildings in this neighborhood are subject to both LPC jurisdiction and DOB review, we handle both permit tracks simultaneously, keeping boards and owners informed as each approval advances.

Bushwick

Bushwick’s mix includes frame houses, masonry rowhouses, and an expanding inventory of converted factory lofts along Flushing Avenue and Morgan Avenue. We take on warehouse-to-residential conversions, full gut renovations of three-family buildings, and rooftop additions where zoning and building envelope allow. For change-of-occupancy conversions that require an Alt-1 filing and a new Certificate of Occupancy, we manage the full DOB process from initial filing through final inspection and CO issuance.

Frequently Asked Questions About Renovation in Brooklyn

Yes. We regularly handle renovations in Park Slope, Brooklyn Heights, Fort Greene, Clinton Hill, Prospect Heights, and Crown Heights North. Landmark district projects require Landmarks Preservation Commission approval before DOB permits can be filed, and we manage both application processes on your behalf, building the LPC review period into the project schedule so that boards and owners have a realistic timeline from the start.

Our crews work throughout Brooklyn from our Park Slope headquarters, including Park Slope, Williamsburg, DUMBO, Brooklyn Heights, Cobble Hill, Carroll Gardens, Greenpoint, Bushwick, Bedford-Stuyvesant, Fort Greene, Clinton Hill, Prospect Heights, Crown Heights, Bay Ridge, Sunset Park, Borough Park, Flatbush, Kensington, Windsor Terrace, and Red Hook. If your neighborhood is not listed, call us to confirm service availability.

Yes. We manage the complete permit and approval process for co-op and condo renovations, including Alt-1 and Alt-2 filings with the NYC Department of Buildings, licensed master plumber and electrician sign-offs, alteration agreement preparation, board package submissions, and insurance certificates naming the building as additional insured. Our active general contractor license (#626219) allows us to file directly with the DOB, and we track all open permits through final inspection and sign-off so that property managers and boards are not left coordinating between agencies.

Structural work including joist repairs, beam installations, and foundation underpinning requires Alt-1 permits with sealed engineering drawings and, in many cases, a special inspection program. Plumbing alterations, electrical upgrades, and mechanical system installations each require separate work permits with licensed master plumber or electrician filings. We prepare and submit all required documentation, respond to DOB objections during plan examination, and attend inspections at every required hold point as part of our standard project process.

Cosmetic updates typically run $10,000 to $30,000. Kitchen remodels range from $25,000 to $75,000 or more, and bathroom renovations from $15,000 to $50,000 or more. Single-floor brownstone renovations typically fall between $75,000 and $175,000, while full gut renovations run $300 to $500 or more per square foot depending on structural scope, landmark requirements, and finish level. We provide itemized estimates after an on-site assessment; all pricing reflects the full cost of permit fees, licensed trade work, and inspections, with no items left for the owner to arrange separately.

Most co-ops require architectural plans, contractor insurance certificates with the co-op named as additional insured, a signed alteration agreement, neighbor notification letters, and proof of licensing. Boards often mandate specific work hours, freight elevator reservations, and refundable security deposits. We prepare complete board packages tailored to each building’s specific requirements and can attend board meetings when a project involves structural work or scope that warrants direct explanation to the board or managing agent.

Yes. We partner with financing providers that offer renovation loans for Brooklyn homeowners, co-op shareholders, and condo owners. Options include home improvement loans, home equity lines of credit, and unsecured renovation financing for projects that do not require a lien on the property. Visit our financing page or call (718) 283-4154 to discuss options that fit your project scope and budget.
