Spray foam insulation in Hemet CA - a sealed attic and a room that stays cool
Hot upstairs and a summer power bill that keeps climbing? Foam seals the gaps as it insulates, so your house holds its temperature.

Is spray foam the right insulation for your Hemet house?
Spray foam insulation in Hemet is a polyurethane foam our crew sprays into your attic, walls or crawl space. It expands into the cracks, so it stops drafts and slows heat in the same layer. It suits some houses and not others, and one visit usually tells us which kind yours is.
Most people call me about a hot upstairs, the room over the garage or a power bill that jumps every summer, and spray foam is one way to deal with it, not the only one. The price moves with how much area you want covered, which foam goes in and how thick, how easy the space is to reach, and whether old insulation needs insulation removal first. The schedule turns mostly on planning, because your household has to be out while the foam goes in, and on a permit if the job needs one. Your written estimate lays out the steps in order and your choices, so you see your own figure before you decide anything.
What our spray foam insulation work covers
Before we talk foam types, I talk with you about your household, because some people are better off with a different product, and about planning your time away from the house while the foam goes in. We settle all of that before we book a spray date. On spray day our crew covers floors and doorways, clears the work area and takes out any wet or dirty insulation we planned to remove, because foam sprayed over a problem just seals it in. Then we spray in even passes, trim anything that needs it and clean up until your home looks the way it did when we arrived.
Spray foam isn't always my first suggestion. It costs more because it seals air while it insulates, and in a lot of attics, sealing the gaps around lights, pipes and the hatch and then topping up with blown-in insulation, loose fill blown through a hose, does the job for less. Foam usually wins when the ductwork lives up in the attic, and if yours doesn't, our attic insulation work covers the other routes.
Permits, inspections and spray foam work in Hemet
In Hemet, the city's Building & Safety Division reviews plans, issues permits and inspects construction across the city, so it's the office that decides whether your spray foam job needs a permit. I check that before we book anything. When a job calls for a permit, we take care of it with the city before the work starts and plan the spray date around the inspection. The city takes permits through an online system now, and since we handle the filing, there's nothing for you to send in.
A lot of the attics we open around Hemet have old insulation packed deep in the middle and thin at the edges, with the eave vents buried, which is backward and leaves the room over the garage baking all afternoon. We check the edges and the vents before we plan anything, and we see the same attics on jobs in San Jacinto and Valle Vista and across this part of Riverside County, well beyond the cities on our pages.

Questions people ask before booking spray foam
How much does spray foam insulation cost in Hemet?
In nearby Riverside, spray foam usually costs about $2,000 to $4,800 for a 1,000-square-foot area sprayed 3 inches thick, and that's the going rate in the area, not a quote from us. Open-cell foam sits toward the low end and closed-cell toward the high end, so the foam you choose moves your number as much as the size does. Your written estimate puts a figure on your own house.
How long do I need to stay out of my house after spray foam insulation?
EPA guidance says to expect to leave the work area before spraying starts, and some foam makers recommend 24 hours before anyone moves back in. That wait before you can come back inside, the re-entry time, changes from product to product. We get it from the maker or supplier of the foam we're using and plan your time away around it, kids and pets included.
Is open-cell or closed-cell spray foam better for my walls?
The better choice comes down to whether your wall needs to dry to the outside. Closed-cell foam, the dense kind that blocks moisture, keeps a frame wall from drying outward at the thickness it's normally sprayed, while open-cell stops air but isn't a vapor barrier. I look at how your walls are built before I recommend one, and the estimate shows you both choices.
Is spray foam safe if someone in my family has asthma or allergies?
EPA guidance says people with a history of asthma, respiratory allergies or skin conditions should read the product information carefully and may want to consider safer alternatives. Tell me at the estimate if that's your house. We'll go over the product information with you before you choose, and that includes insulation that isn't foam.
What paperwork should I get after attic insulation in California?
You should get a written statement from the installer certifying that the new insulation meets the state's requirements, because California's Energy Code requires one for insulation added to an existing attic. I hand it to you when we go over the finished job, so keep it with your other house papers.
How do I handle plumbing or electrical repairs after spray foam is in?
Tell your plumber or electrician about the foam before they start, because EPA says maintenance workers shouldn't heat or grind spray foam, since that can give off toxic emissions. If you already know about new wiring or plumbing work, it usually saves trouble to get it done before spray day.

I do every estimate myself
I look at your house and write the estimate myself, and I'm the one who walks the finished job with you. You deal with one person who knows your house from the first visit to the last.
In business since 2013
We've been in business since 2013, and I came to insulation after years in restaurant kitchens. A kitchen teaches you that the prep decides how the dish turns out, which is why we spend our time on the steps you won't see once the foam is in.
Licensed and insured on every job
We're licensed and insured. California's Contractors State License Board has a C-2 classification for contractors who install insulation, so that's a good license to ask about when you compare bids.
Satisfaction guaranteed, house left tidy
Our promise is satisfaction guaranteed on every job. We also want your home as tidy when we leave as it was when we got there, so cleanup is part of the plan from the start.
On a spray foam job, the most important part is getting the household and the timing right before anyone sprays, so call (951) 484-2035 or send your details through our contact page and we'll start there.
Other insulation work that goes with spray foam
Attic insulation
If your attic needs more than foam, or less, this covers the full range, from topping up what's there to starting fresh after old material comes out.
Blown-in insulation
A good fit for attics that already have some insulation, since we can bring thin or uneven coverage up to an even depth without tearing anything out.
