Hot room over the garage, or a shallow roof with no room for much insulation? Closed-cell foam seals and insulates in a thin layer.
Closed-cell foam insulation is a dense spray foam that seals air gaps and insulates in one rigid layer that won't soak up water. C&L East Los Angeles Insulation installs it in East Los Angeles homes where there isn't room for thick insulation or the spot needs to hold up to moisture.
Most people who call us about foam have a room that stays hot upstairs, a power bill that climbs every summer, or a ceiling with only a few inches between the drywall and the roof, where a blown-in insulation top-up won't fit. The price moves with how many square feet we cover, how thick the foam goes and whether old insulation has to come out first. The schedule turns on that prep work and on when your family can plan to be out of the house. When I come out, I look at the space with you and write down what the job needs and what has to come first.
I come out for every estimate myself, so the person pricing your job is the one who looked in your attic or crawl space. A lead installer runs the crew on the job, and at the end I look over the finished work with you.
I opened this business in 2017 after years of hauling flattened, soaked insulation out of attics around East Los Angeles. That work taught me to deal with wet wood and droppings before anything new goes in, and to tell you when your attic is fine as it is.
We're licensed and insured. California gives insulation contractors their own license class, and you can check any contractor's license with the state licensing board, complaints included. Then call (213) 329-0372 or send us the form to set up a visit.
We reply within one business day. The estimate is free, done on site and comes with no obligation, and I'll write down what your job needs and what has to come first. Have your address, the area you want insulated and any gas furnace or water heater in the attic in mind when you reach out.
For homes under LA County's jurisdiction, LA County Public Works issues building permits, and its list names additions, alterations, repairs, replacements and system upgrades, not insulation by name, so it isn't settled whether a foam job on its own needs one. The county runs an East Los Angeles Building and Safety office for unincorporated county areas and the cities that contract with it, but some cities nearby run their own building departments, so your address decides where you'd apply. We check which office covers your address before anything else, and when a job calls for a permit, we take care of that step with them before work starts.
We're based in East Los Angeles and work across the cities around it, including Montebello and Monterey Park, plus other nearby cities. A lot of the houses we see are older, with low roofs, cramped attics and garage rooms that bake in summer, which is where closed-cell's thin layer earns its cost. Houses here also sit close together, and national building guidance says attics sealed with no roof vents are much more fire safe where neighbors are close, since embers get into vented attics through the vents.
In the Los Angeles area, closed-cell spray foam covering 1,000 square feet at 3 inches thick usually costs about $3,100 to $4,700 per job. That's the going rate around here, not our quote, and your job can land above or below it. Your own number comes from the estimate, once I've seen the space.
Closed-cell is the better pick when space is short, because it's about twice as energy efficient per inch as open-cell, and that's a big part of why it costs more. Open-cell is a much better sound barrier, so it can win on a wall facing a busy street where there's room for depth. I'll tell you which one your space calls for.
Everyone, including other trades, should be out while the foam goes on, and some foam makers recommend 24 hours before you come back for this kind of foam, though that time can vary. That comes from EPA guidance on a page that's now archived, and it's a normal part of planning a foam job. Coming back also waits until the foam has cured and the house has been aired out and cleaned, and the EPA asks for extra care with kids, especially those with asthma, since they play on the floors.
Sort out where that equipment gets its air before anyone talks about sealing the attic. One foam maker's retrofit guide says conventional fuel-burning appliances that pull their air from the attic can't run safely once the attic is sealed with no vents. I look for that equipment at the estimate and we settle it first, then we plan the foam.
It does when the foam's material or the building code calls for it. Federal building guidance says spray foam then gets a thermal or ignition barrier over it, such as a coating or drywall. I note on your written estimate whether your space needs one, so it's part of the plan from the start.
