Common questions
Direct answers from our team. Browse all 40 questions for more depth.
How much does spray foam insulation cost in Cincinnati?
Most Cincinnati homeowners spend $1.50–$2.50 per board foot for closed-cell, $0.50–$1.20 for open-cell. A typical 1,500 sqft attic runs $4,500–$8,500 closed-cell or $2,000–$3,500 open-cell. Free in-home estimates.
Pricing varies with foam type, application thickness, accessibility, and removal of existing insulation. Federal tax credits up to $1,200/year (Section 25C) are available through 2032 for qualifying upgrades.
Should I use closed-cell or open-cell spray foam?
Closed-cell (R-7 per inch) for crawl spaces, rim joists, below-grade, and where vapor barrier matters. Open-cell (R-3.7 per inch) for attics and interior walls where vapor permeability is OK. Both air-seal effectively.
How does spray foam compare to fiberglass and cellulose?
Closed-cell foam: R-7 per inch + air barrier + vapor barrier. Fiberglass: R-3.5 per inch + no air seal. Cellulose: R-3.7 per inch + minimal air seal. Foam outperforms both per inch and as an air barrier.
Are there tax credits for spray foam in 2026?
Yes. Section 25C of the federal tax code provides up to $1,200/year in tax credits for qualifying insulation work through 2032 (Inflation Reduction Act extension). We provide manufacturer-stamped documentation for your tax filing.
How long does spray foam insulation last?
Spray foam doesn’t settle, sag, or degrade like fiberglass and cellulose. Properly installed foam lasts the lifetime of the building (50+ years). Workmanship warranty terms are set by your matched partner contractor and confirmed in writing before work begins.
How much will I save on heating and cooling?
Cincinnati homes typically see 25–45% reduction in heating/cooling bills after attic + rim joist spray foam. Whole-home foam (walls + attic + crawl) commonly cuts bills 50%+. ROI: 4–8 years for most projects.
How long does spray foam installation take?
Attic-only jobs: 1 day. Whole-home retrofits: 2–3 days. New-construction wall foam: 1 day for a typical home. We schedule installs around weather (foam needs ambient temps above 40°F to cure properly).
Can I be home during the install?
You can be in the home but should stay out of the spray-zone for 4 hours after each lift. Most homeowners leave the house for the install day. The chemical odor dissipates within 24 hours.
