Complete Interior Construction Services for NYC Properties

Every surface in your space tells a story. Our interior work services cover everything from framing and drywall to the final coat of paint, delivered by craftsmen who understand the unique demands of NYC construction.

Drywall & Partitions

New drywall installation, metal stud framing, soundproofing assemblies, fire-rated partitions, and Level 5 finishing for flawless walls. We build and finish walls that meet NYC fire code and STC ratings for multi-family buildings.

Plastering & Skim Coating

Traditional three-coat plaster, skim coating over existing surfaces, Venetian plaster finishes, and plaster repair for pre-war buildings. We match existing textures in landmarked and historic NYC properties.

Flooring Installation

Hardwood installation and refinishing, porcelain and ceramic tile, luxury vinyl plank, natural stone, and heated floor systems. We handle subfloor prep, leveling, and moisture barriers for long-lasting results.

Trim, Molding & Millwork

Crown molding, baseboards, wainscoting, chair rails, coffered ceilings, and custom built-ins. From classic pre-war profiles to clean modern lines, we mill and install trim that defines your space.

Painting & Wall Treatments

Interior painting with premium paints (Benjamin Moore, Farrow & Ball), accent walls, wallpaper installation, decorative finishes, and cabinet painting. Proper prep, primer, and application for a finish that lasts.

Soundproofing & Insulation

Acoustic insulation, resilient channel systems, double-layer drywall assemblies, and acoustic sealant details. Critical for NYC apartments where noise transmission between units is a constant concern.

The Asif Contracting Difference

Interior work requires patience, precision, and expertise. Here is why property owners across NYC trust us with their interiors.

Skilled Tradesmen, Not Day Laborers

Our drywall finishers, plasterers, and floor installers are experienced craftsmen with years of NYC project experience. You get precision work, not patch jobs.

Dust Containment & Clean Sites

We use zip walls, negative air machines, and floor protection on every interior job. Your furniture and HVAC system stay clean while we work.

Material Expertise

We guide you through material selection — explaining the real-world differences between LVP and hardwood, Level 4 vs. Level 5 drywall finish, and latex vs. oil-based primers.

Building-Compliant Work

All interior work meets NYC building code, fire code, and co-op/condo alteration agreement requirements. We carry the insurance certificates your building management needs.

Interior Work FAQs for NYC Properties

Common questions about drywall, flooring, plastering, painting, and interior finishing in New York City.

Drywall installation in NYC typically costs $3.50 to $6.00 per square foot for standard 1/2-inch drywall, including material, hanging, taping, and finishing. For fire-rated (Type X) drywall required in many NYC multi-family buildings, expect $4.50 to $7.00 per square foot. Level 5 finishing, which provides the smoothest possible surface for high-gloss paint or critical lighting conditions, adds $1.50 to $2.50 per square foot. Soundproofing assemblies with resilient channels and double-layer drywall run $8 to $14 per square foot. These prices reflect Manhattan and Brooklyn rates; outer borough pricing may be 10-15% lower.
