Why NYC Buildings Need Better Insulation
New York’s buildings face unique challenges. Pre-war brownstones, post-war co-ops, and modern high-rises each have different insulation needs. The insulation NYC buildings were originally built with is often thin, settled, or missing altogether.
Add in our extreme temperature swings from freezing winters to humid summers and most NYC buildings are losing 30-50% of their heating and cooling through poor insulation and air leaks.
The result? Sky-high energy bills, uncomfortable rooms, and HVAC systems working overtime.
We solve this by treating each building individually. Our certified technicians assess your property and pinpoint exactly where you’re losing energy.
We then recommend the insulation solution that makes sense for your building type, budget, and goals.
Insulation Solutions for Every NYC Building
We install every major type of insulation NYC properties call for, each with specific advantages. Our experts help you choose the right material based on your building’s construction, your energy goals, and available rebates.
Where We Insulate
From attic to crawlspace, we install the insulation NYC brownstones, co-ops, and commercial spaces need:
Attic Insulation
Stop heat loss through your roof. Attics account for up to 25% of home energy loss.
Basement Insulation
Control moisture and temperature in below-grade spaces for a comfortable finished basement.
Wall Insulation
Upgrade existing walls without major demolition using our drill-and-fill method.
Crawlspace Insulation
Seal and insulate crawlspaces to prevent cold floors, moisture problems, and pest entry.
Air Sealing
We seal gaps around windows, doors, pipes, and wires before insulating for maximum efficiency.
Firestopping
Meet NYC fire codes with proper firestopping around penetrations and between units.
Fiberglass Insulation
Cellulose Insulation
An eco-friendly option made from recycled paper products, treated for fire and pest resistance. Blown-in cellulose fills irregular cavities completely and provides excellent coverage.

Rockwool Insulation
Made from natural stone, rockwool offers excellent thermal performance plus superior fire resistance and soundproofing. It won't burn, doesn't absorb moisture, and maintains R-value over time.

Sound Proofing
Reduce noise transfer between floors, walls, and from outside. We install specialized acoustic insulation including rockwool, mass-loaded vinyl, and K-13 spray-on acoustic coating.
K-13 Acoustic Spray
A spray-applied cellulose finish for exposed ceilings and walls. K-13 absorbs sound and cuts echo in restaurants, offices, gyms, and parking garages while adding thermal insulation.
