How do I compare spray foam prices before calling anyone?
Ask every pro for pricing per square foot or per board foot. Open-cell foam runs $0.60 to $1.30 per board foot installed, and closed-cell runs $1.30 to $2.90 per board foot. Many pros have minimum job fees of $1,000 to $2,000 or more, so small jobs can cost more per square foot.
What factors change the final price?
Attic floor projects average $1,100 to $6,800, while rafters and roof deck typically cost $1,500 to $9,000. Whether you insulate the attic floor or the roof deck, and the foam type, drive most of the difference. Your quote should spell out the scope.
Should I get a free on-site estimate?
Yes. A local pro can measure the space and confirm which areas need foam before any price is set. Tulsa Foam Pros connects you with independent, insured contractors at no cost to you.
What should I check when hiring?
Confirm the installer's licensing, insurance and spray foam experience before you sign. Ask for proof of insurance in writing. Plan to stay out of the house for about 24 hours after spraying.
What to do next
- Measure your attic floor and roof deck square footage so you can compare quotes against the $1.00 to $4.50 per square foot range.
- Ask each pro whether the quote is priced per board foot or per square foot and whether a minimum job fee applies.
- Request proof of insurance and any required license from the pro before signing, and verify it with the issuing agency.
- Ask whether removal of old insulation is included and get it written into the quote.
