Flossmoor is a century-old village of architecturally significant homes, many of which were built before modern energy codes. According to ENERGY STAR, sealing air leaks and adding insulation can cut heating and cooling costs by about 15%, and older homes have the most to gain.
Across Flossmoor homes, our crews most often find energy escaping through these points:
Flossmoor’s housing stock includes Prairie, Tudor, Spanish, Victorian, and Foursquare homes, many built in the early 1900s. These homes are often solidly built but have empty wall cavities and minimal insulation that careful upgrades can address.
Many Flossmoor homes near the golf club are large, multi-story houses on big lots. Their size means more wall, roof, and floor area to lose heat through, and original plaster construction rarely included insulation in the walls.
In Old Flossmoor, Heather Hill, and Flossmoor Park, the most common gaps are uninsulated walls, thin attic coverage, and air leaks around period windows and doors. A thermal inspection finds each one before work begins.
From attic upgrades to commercial spray foam, we provide a complete range of insulation services for Flossmoor homes and businesses. Every service starts with a free thermal inspection to match the right solution to your property.
Open and closed-cell spray foam seals air leaks and insulates in one step, ideal for Flossmoor crawl spaces, rim joists, and attic conversions.
Dense-pack cellulose made from up to 85% recycled material fills wall cavities in older Flossmoor homes, resisting fire and eliminating cold spots.
We seal every gap, bypass, and penetration in your Flossmoor home with foam, caulk, and mastic, then verify results with a blower door test.
Cost-effective batt and blown-in fiberglass for Flossmoor attics and open wall cavities, using Class A fire-rated, formaldehyde-free products that are safe for family homes.

Foam and fiberglass pipe wrap protects exposed hot and cold pipes in Flossmoor attics, crawl spaces, and basements from heat loss and freeze damage.
Open-cell foam and dense insulation dampen noise between rooms, floors, and exterior walls, ideal for Flossmoor home offices, media rooms, and finished basements.
Blown-in and batt attic insulation brings Flossmoor homes up to the recommended R-49 to R-60, the most cost-effective energy upgrade available.
Insulation in Flossmoor, IL typically costs $1.00 to $4.00 per square foot installed, depending on the material and the area being insulated.

Flossmoor sits in IECC Climate Zone 5, where the U.S. Department of Energy recommends R-49 to R-60 for attics.
Many older Flossmoor homes were insulated to R-11 to R-19 or have no wall insulation at all. Upgrading to R-49 or higher cuts attic heat loss and improves comfort throughout the home.
Area of Home | DOE Recommended R-Value (Zone 5) |
Attic / ceiling | R-49 to R-60 |
Walls (wood frame) | R-13 to R-21 |
Floors | R-25 to R-30 |
Crawl space walls | R-15 to R-19 |
Basement walls | R-15 to R-19 |
We measure your home’s existing R-values during the free inspection and recommend the right levels for Flossmoor’s climate and your budget.

Air sealing rebates reach up to $500 per household, and insulation rebates are applied as an instant discount on your invoice. The work must be completed by a program-approved contractor.
Pre- and post-work attic photos and a blower door test are required, and program funds are limited each year, so booking early matters.

IHWAP is available to households at or below 200% of the federal poverty line and is administered through local community action agencies. We can point you to the right agency to apply.
No. The federal 25C Energy Efficient Home Improvement Credit expired on December 31, 2025, and does not apply to insulation installed in 2026 or later.

For 2026 projects, the Nicor Gas, ComEd, and Illinois weatherization programs above are the way to reduce your out-of-pocket cost.
