Insulation Company in Boulder Creek, CA

Why Boulder Creek Homes Are Different
Boulder Creek’s heavily forested setting in the Santa Cruz Mountains means insulation work here is largely about defending against persistent moisture, wood-boring pests, and wildfire ember intrusion, rather than just temperature control. A large share of the homes are rustic 1920s to 1970s redwood cabins and A-frames on steep, shaded lots with post-and-beam construction, minimal wall cavities, and open attics or inaccessible kneewalls that make retrofitting insulation physically difficult. Many of these older Boulder Creek cabins have “remodeled” additions where insulation was installed backwards or omitted behind shiplap, so you often find hidden thermal bridges where morning fog condenses on interior walls. We plan around that reality: moisture-resistant materials, real vapor management, and an honest read on what an older cabin can actually take. It’s not uncommon to find fiberglass batts that have been sitting damp for years, holding mold and rot against the framing.
Our Main Boulder Creek Services
Boulder Creek homeowners most often call us about two things: attics that leak heat all winter and crawlspaces that wick moisture straight up into the floors. These are the three services we run in Boulder Creek, each with a dedicated page covering pricing and specifics.
Attic Insulation in Boulder Creek
Attic work in Boulder Creek usually means pulling out damp, compressed batts and starting over with a material that can handle the humidity. Older cabin attics here are often open to the elements at the eave edges, which means we address air sealing and ember-resistant venting in the same visit. If your upstairs bedrooms swing hot and cold and the ceiling feels damp to the touch in January, it’s worth a look. Full details are on our Attic Insulation in Boulder Creek page.
Spray Foam Insulation in Boulder Creek
Spray foam makes real sense in Boulder Creek crawlspaces and under floors, where groundwater vapor and fog drip are constant. It air-seals as it insulates, and it won’t wick moisture the way fiberglass does. For older A-frames with almost no wall cavities, we can use spray foam to create an air and moisture barrier without tearing out shiplap. See what’s involved on the Spray Foam Insulation in Boulder Creek page.
Blown In Insulation in Boulder Creek
Blown-in insulation (loose fibers blown into the attic cavity to fill every gap) works well in Boulder Creek attics where the framing is irregular and the joist spacing isn’t uniform, which is common in older mountain cabins. The trick here is keeping the material dry and keeping the vents clear so that fog drip doesn’t settle into the fiber. We go over the details and pricing on the Blown In Insulation in Boulder Creek page.

Most insulation replacement and top-up work doesn’t require a permit, but if we’re changing the building envelope, like spray foaming a crawlspace or air sealing in a way that affects ventilation, the county may want a look.
