Find Insulation Contractors Near You
Proper insulation reduces heating and cooling costs by 20% to 40%, making it one of the highest-ROI home improvements available. Browse our directory to find licensed insulation contractors who can assess your home’s insulation needs and install the right materials — from blown-in cellulose and fiberglass to spray foam and mineral wool.
Types of Insulation Projects
Attic insulation is the most common and impactful project, since heat rises and an under-insulated attic is the biggest energy drain in most homes. Costs range from $1,500 to $3,500 for a typical attic. Read our attic insulation cost guide.
Spray foam insulation provides both insulation and air sealing in one application, making it ideal for crawl spaces, rim joists, and homes with significant air leakage. Costs run $1.00 to $3.00 per board foot depending on open-cell vs closed-cell. Read our spray foam cost guide.
Wall insulation, crawl space encapsulation, and basement insulation are also common contractor services. An energy audit can identify which areas of your home need insulation most urgently.
Choosing an Insulation Contractor
Look for contractors with a valid state contractor license, liability insurance and workmanship warranty, BPI (Building Performance Institute) certification (indicates training in building science), experience with your specific insulation type (spray foam requires specialized equipment and training), and willingness to perform or work from a blower door test to measure improvement.
Get at least 3 quotes. A good contractor should visit your home, inspect the areas to be insulated, and provide a detailed written estimate — not just a phone quote based on square footage.
Incentives
The Inflation Reduction Act provides a 30% tax credit (up to $1,200/year) for insulation improvements. Many utility companies offer additional rebates of $200 to $1,000. Check your state incentive programs for the full list of available savings.
