Where it goes
Tap a spot to see what foam does there.
Most homes leak the most air in the same five places. Here’s what each one costs and which foam fits.
Attic & roofline
Spraying the underside of the roof deck turns the attic into conditioned space—ideal when ductwork or an HVAC unit lives up there.
- Typical foam
- Usually open-cell, about 5.5″
- Typical price
- $2.20–$3.50 per sq ft
Exterior walls
Fills every gap around outlets, wiring and framing, so walls stop leaking air. Best done during a remodel or new build while the studs are open.
- Typical foam
- Open-cell 3.5″ or closed-cell 2″
- Typical price
- $1.20–$4.00 per sq ft
Rim joists
The band of framing that sits on your foundation is one of the leakiest spots in most homes—and one of the cheapest to fix.
- Typical foam
- Closed-cell, about 2″
- Typical price
- $3.00–$5.00 per linear ft
Crawlspace
Sealing and insulating crawlspace walls keeps damp, cold air from creeping into the floors above.
- Typical foam
- Closed-cell, about 2″
- Typical price
- $2.00–$3.50 per sq ft
Basement & foundation walls
Closed-cell foam on foundation walls insulates and helps keep moisture out of finished basement space.
- Typical foam
- Closed-cell, about 2″
- Typical price
- $2.00–$3.50 per sq ft
Pole barns & metal buildings
Closed-cell foam on the metal panels stops the condensation that “rains” inside uninsulated buildings and keeps shops comfortable year-round.
- Typical foam
- Closed-cell
- Typical price
- Priced per building
Commercial roofs & buildings
Spray polyurethane foam (SPF) roofing creates a seamless, insulated roof surface with no seams to leak.
- Typical foam
- High-density roofing foam + coating
- Typical price
- Priced per project

Questions

We aim to follow up within one business day by phone or email to confirm your project and connect you with a contractor near you.
How much does spray foam insulation cost?
Most 2026 projects land between $1.20 and $4.00 per square foot depending on foam type and thickness, and rim joists run about $3–$5 per linear foot. A typical 2,000 sq ft home done top to bottom is roughly $10,000–$16,000. Use the estimator above for a ballpark, then get an exact quote.
Should I use open-cell or closed-cell foam?
Open-cell is the value pick for attic roof decks and walls that stay dry. Closed-cell costs more but adds a vapor retarder and roughly double the R-value per inch, so it’s the usual choice for crawlspaces, basements, rim joists and metal buildings.
Is spray foam safe for my family?
Once it’s fully cured, spray foam is inert. During installation the chemicals do need to cure, so everyone stays out of the house during spraying and for the re-occupancy time the installer and manufacturer specify—often around 24 hours. A professional crew also ventilates the work area.
