Spray foam seals and insulates in one step, making it the strongest option for crawl spaces, rim joists and hard-to-reach attic areas. We install both open- and closed-cell foam across the Portland metro.
Open-cell foam (~R-3.5/inch) is lighter, more affordable and great for interior walls and attics where sound dampening helps. Closed-cell foam (~R-6.5/inch) is denser, adds structural rigidity, blocks moisture, and is our go-to for crawl space walls and rim joists.
Unlike batts, foam expands to fill gaps and stops the air leaks that drive Portland heating bills. Closed-cell foam also acts as a moisture barrier — valuable in our wet climate.
Crawl space encapsulation, rim joists, vaulted and cathedral ceilings, bonus rooms over garages, and additions. Pair it with attic insulation for whole-home comfort.

Yes. Once cured, professionally installed foam is inert. We follow proper ventilation and re-occupancy guidelines during and after install.
Closed-cell, in most Portland crawl spaces — it resists ground moisture and adds an air and vapor barrier in one.
About R-3.5/inch open-cell and R-6.5/inch closed-cell, so it hits high R-values in less depth than batts.
