Apartment Renovation Services in New York City

Our Apartment Renovation Services

Open Floor Plan Conversions

Many NYC apartments — especially pre-war units — feature compartmentalized layouts with small, isolated rooms that limit functionality. We work with structural engineers to identify non-load-bearing walls that can be removed to create open-concept living spaces. When load-bearing walls are involved, we design and install steel beams or headers with proper DOB permits and structural sign-offs. The result is a modern layout that improves natural light, traffic flow, and overall livability.

Kitchen Renovation

Apartment kitchen remodeling in NYC requires navigating shared plumbing stacks, limited electrical capacity, and building-specific appliance requirements. We redesign layouts to improve the work triangle, install custom cabinetry maximized for vertical storage, and coordinate plumbing and electrical rough-ins for modern appliances. From galley kitchen transformations to full gut-and-rebuild projects, our team handles every detail from DOB permits to final hardware installation.

Bathroom Renovation

Apartment bathroom renovations demand proper waterproofing, coordination with building plumbing stacks, and compliance with noise restrictions. We install walk-in showers, modern vanities, and heated floors with full membrane waterproofing systems. Our plumbers work with existing stack locations and vent configurations specific to NYC apartment buildings.

Flooring Throughout

We remove existing flooring and prepare subfloors with proper leveling compounds before installing new materials. Options include hardwood refinishing, engineered wood, luxury vinyl plank, and tile — each installed with appropriate underlayment and sound-dampening membranes required by many NYC co-op and condo buildings.

Electrical System Upgrades

Pre-war apartments frequently have 60-amp panels, knob-and-tube wiring, or insufficient circuit capacity for modern living. We install 200-amp panel upgrades, dedicated appliance circuits, GFCI protection, and LED lighting throughout — bringing apartments into compliance with current National Electrical Code requirements.

Plumbing System Replacement

Aging galvanized supply lines and cast iron drain stacks corrode over time, reducing water pressure and creating leak risks. Our licensed plumbers replace deteriorated piping with copper or PEX supply lines and PVC drains where building codes permit, coordinating with building management for stack access and water shutdowns.

Interior Painting and Finishing

Every apartment renovation includes professional painting — walls, ceilings, trim, and doors. We skim-coat damaged plaster walls common in pre-war buildings, apply proper primers for new drywall, and finish with premium paints in your selected colors. Our painters work after all trades are complete to ensure clean, damage-free results.

How Much Does an Apartment Renovation Cost in NYC?

Apartment renovation costs in New York City vary significantly based on scope, materials, and building type. Here are general ranges based on our project history:

Cosmetic Update (paint, fixtures, hardware, minor repairs): $15,000–$30,000

Mid-Range Remodel (kitchen, bathroom, flooring, painting): $50,000–$100,000

Full Gut Renovation (layout changes, all new systems, custom everything): $150–$400+ per square foot

Several factors impact cost in NYC specifically:

  • Co-op and condo board requirements add administrative costs for alteration agreements, insurance certificates, and building management coordination
  • Pre-war buildings often require extensive plumbing, electrical, and plaster work beyond what’s visible during initial assessment
  • Material delivery logistics in Manhattan (elevator reservations, street parking permits, loading dock scheduling) can add to labor costs
  • DOB permit fees and expeditor costs vary by scope
  • Building-mandated work hours (typically 8am–5pm weekdays) extend project timelines compared to single-family homes

We provide itemized estimates that separate demolition, rough carpentry, mechanical systems, finish materials, and labor so you know exactly where your budget goes.

Pre-War Apartment Renovation

Pre-war apartments (pre-1940s) feature plaster walls, original hardwood floors, higher ceilings, and aging mechanical systems. We specialize in preserving architectural details — crown moldings, archways, original doors — while bringing plumbing, electrical, and HVAC systems up to modern standards. Proper lead paint handling under our EPA certification (NAT-F277952-1) is standard procedure for these buildings.

Co-op and Condo Apartment Renovation

Board approval processes vary by building, but we maintain all required documentation — insurance certificates, contractor licenses, work schedules, architectural plans, and noise mitigation protocols — ready to submit. Our familiarity with alteration agreements across hundreds of NYC buildings reduces approval timelines significantly.

Brownstone Floor-Through Apartments

Brownstone apartments often span a full floor with unique layout challenges including railroad-style rooms and plumbing located on exterior walls. We handle structural modifications to reconfigure these spaces while respecting the building’s historic character and any landmark preservation requirements.

Loft Apartments

Converted commercial lofts require specialized renovation approaches for open-plan living spaces — including exposed systems, concrete floors, and non-standard ceiling heights. We design and build partitions, mezzanines, and custom storage that work with the loft’s industrial character.

Frequently Asked Questions About Apartment Renovation in NYC

Most apartment renovations require 6–12 weeks from demolition through final inspection, depending on scope and material availability. Full gut renovations of larger apartments may take 3–6 months. Projects involving structural modifications, co-op board delays, or landmark approvals may extend timelines due to additional review processes.

Apartment renovations range from $15,000 for cosmetic updates to $150–$400+ per square foot for full gut renovations. Costs depend on apartment size, material selections, structural complexity, and building-specific requirements like co-op alteration agreements.

Cosmetic updates and single-room projects often allow continued occupancy, while gut renovations typically require temporary relocation due to utility shutdowns, dust, and safety concerns.
