Open-cell foam insulation in Simi Valley CA - a quieter, cooler upstairs

Most calls I get start with a hot room over the garage, a drafty upstairs or a power bill that climbs every summer, and foam is sometimes the answer and sometimes not. The price moves mostly with how much roof or wall area we cover and whether old insulation has to come out first, and the schedule turns on that same prep plus the day your household spends away from the house. When I walk the space with you, I put the scope in writing so you can see exactly what's included before you decide.

First I look at what's already up there and why the room is hot, because a roof leak or old wiring gets fixed before any foam goes over it. Next our crew covers your floors and anything we're not spraying, pulls out old insulation that's wet or full of droppings so the problem doesn't stay behind, and closes off the work area. Then we spray the foam to the depth the scope calls for, and since open-cell lets moisture pass through it, in an attic we build the way moisture gets out into the plan from the start instead of adding it later. If the foam maker or the code calls for a covering layer over the foam, like a coating or drywall, that goes on before we're done.

Open-cell can't stop water vapor, so where a house needs a vapor layer, like over the bare dirt in a crawl space, we put down a crawl space vapor barrier made for that job rather than counting on the foam. The same knack for soaking up sound makes open-cell a common pick in offices and shops, which we handle as commercial insulation.

Simi Valley's Building and Safety Division reviews plans and inspects projects across the city to check they meet California's building and energy codes. The state energy code sets some insulation standards by climate zone, so what your attic has to meet follows where Simi Valley sits on that map, and we plan the foam with that in mind. If you have questions about the city's building rules, the Building and Safety line is (805) 583-6723.

A lot of what I find in attics here is older insulation packed deep in the middle and thin at the edges, with open gaps around lights, pipes and the hatch, and summer heat on the roof makes that show up fast in the rooms below. We see the same thing on jobs in Moorpark and Thousand Oaks, and we work across the cities around Simi Valley in Ventura County and the nearby parts of Los Angeles County, so if you're not sure we cover yours, just ask.
