What should a landlord do this week to get started?
Request a written site walk of the attics and rim joists at each of your 6 rentals. Pricing depends on foam type, R-value and project size, so a walk gives you accurate numbers. Ask each pro for a written quote that lists foam type, thickness, board feet and cleanup.
What should you check when hiring or switching a spray foam pro?
Ask the pro for proof of licence and insurance before work starts. Oklahoma code requires the installed R-value and foam thickness to appear on the installer's certificate, so request that certificate for every job. Keep these certificates on file, since they help when you change contractors or verify past work.
What R-value targets should attic work meet in Oklahoma?
Oklahoma residential guidance lists R-38 for ceilings and attics in Climate Zone 3 and R-49 in Climate Zone 4. Total finished attic insulation must be at least 13 inches deep or R-38. Check each quote against these targets before you approve the scope.
Which foam type fits attics and rim joists?
Open-cell foam is rated around R-3.5 to R-3.6 per inch, while closed-cell is around R-6 to R-7 per inch. Closed-cell is commonly used at rim joists because it delivers more R-value in less space and adds rigidity. Ask the pro which type fits each space and why.
What to do next
- Request a written site walk covering attics and rim joists at all 6 rentals before comparing prices.
- Ask each pro for a quote listing foam type, thickness, board feet and cleanup, since bids are often priced by the board foot.
- Ask for proof of licence and insurance, and request the installer's certificate showing installed R-value and foam thickness.
- Compare each attic scope against the Oklahoma target of R-38 (Climate Zone 3) or R-49 (Climate Zone 4) before approving work.
