Insulation Contractors in New York

How to Hire an Insulation Contractor in New York

Insulation contractors add or upgrade insulation in attics, walls, crawl spaces, basements and rim joists, and often seal the air leaks that let conditioned air escape. Insulation works best together with air sealing, and the right material depends on where it goes and how moisture moves in that part of the house. Consider it when rooms are drafty, energy bills are high or the attic insulation looks thin.

What to check before you hire

• Ask them to air-seal attic penetrations such as top plates, light fixtures and chases before adding insulation.
• Ask what R-value they recommend for your climate zone and how they will measure installed depth.
• Make sure soffit vents stay open with baffles so the attic can still ventilate.
• Ask how they will handle old knob-and-tube wiring, recessed lights not rated for contact, or signs of pests or mold.
• Ask whether an energy audit or blower door test is available so you can see results before and after.

Questions to ask every contractor

• Which material do you recommend for this area: blown-in, batts or spray foam, and why?
• Will you remove the old insulation, or add on top of it?
• How do you prevent moisture problems in walls or crawl spaces?
• Are there utility rebates or tax credits that apply to this work?

Frequently asked questions

How do I know if I need more insulation?

Uneven temperatures, drafts, high energy bills, ice dams, or attic insulation at or below the top of the floor joists are common signs. An energy audit can pinpoint where heat is being lost.

Spray foam or blown-in insulation?

Spray foam also air-seals and suits tight or irregular spaces, while blown-in cellulose or fiberglass is a common choice for open attics. The best option depends on the location and your goals.

Does insulation need a permit?

Adding insulation to an attic is often permit-free, but work in walls during a remodel, or projects tied to energy code requirements, may need one. Your contractor should know local rules.
