Closed-cell foam insulation in Menifee CA - foam that keeps air and moisture out
Hot upstairs, a damp crawl space or ducts baking in the attic? We spray dense foam that seals the air out while it insulates.

I come out and price it myself
I look at the attic, crawl space or walls myself and write up the estimate. Our installers do the work, with me or a lead installer running the job, so the plan you agreed to is the one that gets sprayed.
Started in 2017, after HVAC work
I spent years in HVAC running duct through attics and crawling past insulation done wrong or never done. I started this business in 2017 to do it in the right order, with problems fixed and leaks sealed before insulation goes in.

Closed-cell foam insulation in Menifee
Closed-cell foam insulation in Menifee, CA is a dense, rigid spray foam that insulates, stops air leaks and, at normal thickness, lets almost no moisture vapor through. It helps houses with ducts in a hot attic, a damp crawl space or a room that won't stay comfortable.
Most people who call about closed-cell have a room that won't hold its temperature, a power bill that keeps climbing or a crawl space that smells damp. Before I price foam, I check how many inches are already up there, what shape they're in and how old the house is, because soaked or dirty insulation has to come out first and older houses usually have more gaps to deal with.
The price moves with the square footage, how thick the foam goes, how easy the space is to reach and how much removal or repair comes first. The schedule turns on that prep, on whether your job needs a permit, and on the weather, since temperature and humidity play a big part in how spray foam cures, so ask us which time of year suits your job. The written estimate spells out the scope and the price for your house.
How we handle closed-cell foam insulation
Where closed-cell is worth the price
Closed-cell costs more, so I recommend it where you need its moisture control or its extra strength, such as a damp crawl space or an attic where your ductwork runs. If the ducts aren't up there, sealing the gaps and topping up the loose fill usually does the job for less, and if open-cell foam insulation fits your house better, I'll tell you that too. Every job is backed by our satisfaction guarantee.
Fix it and seal it first
We do the insulation removal before we spray when the old material is soaked or full of droppings, because foam over it just locks the problem in. A roof leak or bad wiring gets fixed first too, since closed-cell is rigid and hard to get back through once it's on. We make sure the gaps around can lights, pipes and the hatch are closed, and we spray an even layer right out to the edges, where thin spots usually hide.
Menifee homes and commercial buildings
Most of our calls come from homeowners, but property managers call too, and the same foam fits commercial insulation work where a building needs moisture control or extra strength. Menifee requires a city business license from every contractor who pulls a permit, and state law says all insulation sold and installed in California has to be certified to the state's quality standards. We're based in Menifee and work across this part of Riverside County, including Murrieta, Perris and Lake Elsinore.

(951) 430-8005What happens after you call
I look at the space
You call or send the form. I come out, look at the space, point out anything that has to be fixed before foam goes on and send you a written scope with the estimate, so you know what we'd do and why.
Permit question and prep
Once you say go, we find out whether your address falls under the city or the county, ask that office what the job needs and pull the permit when one is required. Then we do the prep the scope calls for.
Spraying, inspection and walkthrough
Our installers spray the foam with me or a lead installer running the job. When there's a Menifee permit, the city inspects at key stages and approves each one before the final inspection, and once we're finished I walk you through the work.
Closed-cell foam questions from Menifee homeowners
Is closed-cell foam worth the extra cost over open-cell?
It is when you need heat control and moisture control more than a lower price. Closed-cell is about twice as energy efficient per inch as open-cell, and at normal thickness it lets almost no moisture vapor through. Open-cell costs less and is much better at cutting noise, so it suits jobs where quiet matters more than moisture.
How much does closed-cell spray foam cost in Menifee?
In Riverside, closed-cell spray foam usually costs about $3,200 to $4,800 for 1,000 square feet at 3 inches thick. That's the going rate in the area, not our quote, and your job moves with the size, the thickness and the prep. Your own number comes from the written estimate after I've seen the space.
How long do we stay out after closed-cell spray foam?
Plan on at least 24 hours away, since safety guidance says to leave during the install and stay out for at least that long after, so line up a place for you, the kids and the pets. The guidance also says to wait until the foam has cured and the house is aired out and cleaned before you move back in.
Which California contractor license covers spray foam insulation?
The C-2 Insulation and Acoustical Contractor classification covers it, and the state licensing board describes that class as contractors who install any insulating material for temperature or sound control. Spray foam is insulating material used to control temperature, so it falls in that class. It's a fair question to put to anyone who bids your job.
