Closed-cell spray foam acts as a vapor barrier, meaning it does not absorb moisture. This is critical in Everett to prevent mold growth and wood rot within your walls, unlike traditional fiberglass which can trap dampness.
Absolutely. Once the foam has fully cured (typically within 24 hours), it is completely inert and off-gasses no harmful chemicals. It actually improves indoor air quality by blocking outdoor allergens and pollutants.
In most cases, we recommend removing old, degraded insulation (like old batts or blown-in cellulose) to ensure the spray foam adheres directly to the substrate, creating a perfect airtight seal.
Yes, spray foam is an excellent sound dampener. Open-cell foam, in particular, is highly effective at absorbing mid-to-high frequency sounds, significantly quieting the interior of homes near busy roads or flight paths.
Most residential projects, such as an attic or crawl space, can be completed in a single day. Larger commercial projects or full-house installs may take two to three days depending on the square footage.
