NYC Interior Renovation Contractor | Full Home Renovations | Nexus Construction Group Inc
Interior Renovation, NYC

One Team, Responsible for Every Wall, Wire, and Finish

Most NYC interior renovations fail on coordination, not craftsmanship — a designer's vision that the contractor never fully executes, or a contractor's shortcuts the designer never catches. Nexus Construction Group Inc runs design and construction as one accountable process, so the layout drawn on day one is the layout you walk into on move-in day, whether the project is a modern Manhattan condo or a pre-war Brooklyn brownstone.

Full-Service Approach

Design, Demolition, Structural Work, and Finishes Under One Contract

A full interior renovation touches nearly every trade in a building: structural engineering for wall removal, electrical and plumbing rough-in, HVAC routing, drywall and plaster repair, flooring, millwork, and final finish carpentry. When these are managed by separate vendors, gaps and finger-pointing are almost guaranteed. Nexus manages the entire sequence internally.

This also means faster decision-making. When a structural surprise appears behind a wall, our team resolves it the same day rather than waiting on a separate designer and separate contractor to coordinate a fix.

  • In-house design development with 3D renderings before construction begins
  • Structural engineering coordination for load-bearing wall changes
  • Electrical, plumbing, and HVAC system upgrades behind original walls
  • Custom millwork, built-ins, and closet systems fabricated to fit
  • Historic detail preservation for pre-war moldings, floors, and doors

FAQ

Interior Renovation Questions, Answered

How much does a full interior renovation cost in NYC?
A full interior gut renovation in NYC typically ranges from $150 to $350 per square foot depending on finish level, meaning a 1,200 sq ft apartment often runs $180,000 to $420,000 for a complete renovation.
How long does a full apartment gut renovation take?
A complete gut renovation of a NYC apartment typically takes 4 to 8 months from permit approval to final walkthrough, depending on square footage, structural changes, and building approval timelines.
Can you move walls in a NYC co-op or condo?
In most cases, yes, provided the wall is non-load-bearing or a structural engineer approves a load-bearing modification. Co-op and condo boards typically require an alteration agreement before this work begins.
Do you handle the full design and construction process?
Yes. Nexus manages design development, material selection, permitting, demolition, structural work, and finish installation as a single accountable team rather than separate designer and contractor relationships.
Can you renovate a pre-war brownstone interior while preserving its character?
Yes. We regularly restore original moldings, hardwood flooring, and pocket doors while modernizing electrical, plumbing, and HVAC systems behind the walls.
Will I need to move out during the renovation?
For full gut renovations involving plumbing and electrical rough-in, yes, most clients relocate for the core construction phase. We provide a phase-by-phase schedule so you know exactly how long that period will last.
