Rim Joist Spray Foam Insulation in Tulsa, OK
The rim joist is the band of framing that sits on top of your foundation wall and closes off the floor system around the perimeter of your house. It's one of the most overlooked air leakage points in Tulsa homes. Most builders stuff it with fiberglass batts that fall out or compress over time, and the gaps let cold air pour in every winter. Closed-cell foam applied directly to the rim joist seals and insulates in one application.

When to Call
When You Need Rim Joist Spray Foam Insulation
- Your basement or crawl space floor is noticeably cold even when the furnace runs constantly

How It Works
Our Process for Rim Joist Spray Foam Insulation
- 1
Access and Condition Check
We access the rim joist from the basement or crawl space and remove any old batt material present.
- 2
Surface Cleaning
Wood surfaces must be dry and free of mold or debris before closed-cell foam will bond correctly.
- 3
Closed-Cell Application
We spray closed-cell foam to the full depth of the rim joist cavity, covering the sill plate and band board.
- 4
Visual Confirmation
Every bay is checked for voids before we pack up — a missed bay defeats the whole purpose of the job.
Tulsa Context
Why this matters in Tulsa
Tulsa's ice storms and extended freezes — like the ones in February 2021 — hit uninsulated rim joists hard. That's when pipe freezes along exterior walls become real problems, not just theoretical ones.
Straight Talk
About pricing & scope
Rim joist jobs are priced by linear footage and access difficulty. Finished basements where we have to work around mechanicals or low clearance areas take longer and affect the final scope.
