Crawl Space & Rim Joist
Damp crawl spaces destroy subfloors and drive up energy bills. Our closed-cell foam seals the entire envelope — moisture, pests, and air infiltration gone — adding structural rigidity as a bonus.
About Crawl Space & Rim Joist
A vented crawl space is a liability in the Texas climate. Warm humid air enters from outside, contacts your cool subfloor, and condenses — feeding mold, rotting joists, and creating the perfect environment for pests. If you have hardwood floors that squeak or buckle, a crawl space moisture problem is often the culprit.
We seal the entire crawl space envelope: perimeter walls, rim joists, and any penetrations. Closed-cell foam is the only appropriate product here — its vapor-impermeable cell structure creates a true moisture barrier, not just a thermal one.
The result is a dry, conditioned crawl space that protects your subfloor investment, eliminates the floor-temperature differential you feel in winter, and adds measurable structural rigidity to the rim joist — which building engineers increasingly specify as a seismic retrofit.
Common Questions
Should I encapsulate or spray foam my crawl space?
For most DFW homes, spray foam on the walls and rim joists outperforms encapsulation alone because it addresses both the thermal boundary and the moisture barrier in a single product. We can combine both methods for extreme moisture situations.
How do I know if my crawl space needs attention?
Floors that feel cold in winter, musty odors in the lowest floor of the house, or visible efflorescence on your foundation walls are all indicators. We will assess it for free during your estimate visit.
