What type of contractor should do crawl space spray foam work?
Crawl space spray foam is usually done by insulation contractors and spray foam specialists rather than general handymen. The work involves insulation and air sealing, so the installer should understand Oklahoma's residential energy code. Ask the pro for proof of licence and insurance before work starts.
What insulation levels does Oklahoma code require for crawl spaces?
Oklahoma's residential energy code sets crawl space wall insulation requirements that depend on climate zone. The 2015 Energy Code Compliance Guide lists at least R-10 or 10/13, and the summary of key residential code requirements lists R-5 continuous insulation or R-13 in Climate Zone 3. Your installer should confirm which applies to your home.
How long does crawl space encapsulation take?
A crew of two can often finish a standard encapsulation in 1 to 3 days for a 1,000 to 1,500 square foot crawl space when drainage is not required. If drainage is needed, add 1 to 3 more days. Mold remediation can add another 0.5 to 1.5 days.
Why does sealing a crawl space matter?
The U.S. Department of Energy notes that air sealing and proper insulation are key home-efficiency measures. DOE also states that a sealed crawl space can reduce moisture and improve comfort when properly detailed.
What to do next
- Ask each contractor for proof of licence and insurance before you sign anything.
- Request a written quote that lists the crawl space wall insulation type and R-value.
- Ask whether the quote includes vapor control, air sealing, and any drainage or mold work.
- Confirm the R-value meets the Oklahoma residential energy code for your climate zone.
