It depends on which area of your home we are insulating. Open-cell foam is soft, expands generously, and deadens outside road and raceway noise—making it the best choice for enclosing residential attic roof decks and interior bonus room walls. Closed-cell foam is dense, rigid, and blocks water vapor completely—making it the right choice for damp Piedmont crawl spaces, rim joists, metal buildings, and pole barns.

Yes. In a traditional vented attic with fiberglass on the floor, summer roof temperatures in Concord easily reach 135°F to 145°F—baking the AC ductwork and bonus rooms right below. Sealing the underside of your roof deck with open-cell spray foam stops solar heat at the roof line and drops attic temperatures to within 5 to 10 degrees of the living space below.

Most Concord residential attics, crawl spaces, and metal shops are completed in a single day. While our crew is actively spraying and for 12 to 24 hours afterward while the foam cures and our high-powered exhaust fans ventilate the work zone, people and pets should stay out of the house. Once cured, the foam is completely inert, odorless, and safe for your family.

Yes. Before spraying an existing attic floor or crawl space, old fiberglass batts or blown-in cellulose must be cleared out so the spray foam can bond directly to clean wood decking and joists. Our crew uses industrial HEPA vacuum hoses located outside on our rig to suck old insulation out of your house without tracking dust through your hallways.

Yes. Nearly 40% to 50% of the air you breathe on your first floor rises up from the crawl space underneath via the stack effect. By sealing your crawl space walls and rim joists with water-resistant closed-cell spray foam and installing a thick floor vapor barrier, we lock out damp red-clay ground moisture, stop hardwood floor cupping, and eliminate musty downstairs odors.

Yes. Under IRS Section 25C (Inflation Reduction Act), homeowners who add qualifying spray foam insulation and air sealing to their primary residence can claim a federal tax credit of 30% of the material cost, up to $1,200 per year. We provide an itemized invoice breaking out material and labor costs for your tax records.

Absolutely. Uninsulated steel buildings around Mount Pleasant, Midland, and rural Concord suffer from severe roof condensation ('building rain') and blistering summer heat.
