Hot upstairs, drafts you can't find, or street noise through the ceiling? We seal the roofline with foam so the rooms below stay comfortable.
Open-cell foam insulation is a soft spray foam that seals air leaks while it insulates, and on most Redondo Beach jobs we spray it under the roof so the attic stops passing heat, drafts and noise into the rooms below.
Most people who call me about foam have a room that never feels right, usually upstairs or over the garage, or an older attic nobody's looked at in years. The price comes down to how much roofline we're covering, how thick the foam goes, and whether old, dirty insulation has to come out first through insulation removal. The schedule mostly turns on your roof, because any repairs come before the foam, and on the time you'll spend away while it cures. You'll get your own figure after I've walked the house with you, along with photos of what I found and a written plan.
I do the estimates myself and walk the house with you, attic and roof included, so you see what I see. Our crew does the install, and I come out on site to check the work before we call it done.
I learned this trade on other crews and started this business in 2023. If sealing the gaps and topping up what's already there will fix your problem, I'll tell you that before I'd sell you foam, because foam costs more and isn't always the answer.
We're licensed and fully insured. California's licensing board lets someone without a license take on only minor work up to $1,000, and only when it needs no permit and they have nobody working for them, so ask anyone spraying foam in your house for a license.
I'd rather you understand your own attic than just take my word for it, so ask me anything at the estimate. The work is backed by our satisfaction guarantee. To get started, call (424) 254-3847 or send the form on this page.
Send the form or call (424) 254-3847, and we'll reply within one business day to set up a free estimate at your property, with no obligation. I'll walk the attic and roof with you, then send photos of what we found and a written plan that shows what comes first and why. If you know the roof's age, any leak history and roughly how big the attic is, have them handy.
Permit applications in Redondo Beach go through the city's online portal, and paper application forms aren't accepted anymore. I won't guess whether a foam job at your address needs a permit, so we look up what the city or the county asks for, handle the application as part of the job when one's called for, and I'll tell you at the estimate what we found.
Near the coast, salt spray is a real corrosion worry for metal truss plates, steel framing and connectors in a vented attic, and building guidance notes that a sealed, foamed attic has no vents for that salty air to get in through. The trade-off is that a sealed attic needs a way to get rid of moisture, so I'll go over how yours will handle that at the estimate. We do this work across the South Bay, in Torrance, Hermosa Beach, Manhattan Beach, Gardena and other cities nearby, and older houses with ducts running through a hot attic are one of our most common calls.
Open-cell usually suits an attic roofline, and closed-cell suits tight spaces or spots where moisture is the worry. Open-cell slows heat at about R-3.6 per inch and stops air at typical thicknesses, while typical closed-cell foam reaches about R-6 per inch, is rigid and blocks moisture vapor that open-cell lets through. I'll show you which one fits your house at the estimate.
Have the roof inspected and any leaks and the damage they caused repaired before foam goes under the deck, because that's what building guidance calls for. If the roof is at or near the end of its life, replacing it first may make more sense, so it's worth putting roof work into your budget from the start. I check the roof at the estimate, as I covered above, and tell you what I find.
Plan to be out while the crew sprays and until the foam has cured and the house has been aired out and cleaned. Some foam makers recommend 24 hours before anyone goes back in, and the time can vary by product, so line up a place for the family and pets to stay. I'll tell you the re-entry time, when it's okay to come back, for the foam we're using well before spray day.
Spray foam insulation around Los Angeles usually costs about $2 to $5 per square foot, and that's for spray foam in general, not our price. Where your job lands depends on the area, the foam depth and any work that has to come first. Your own figure comes in the written plan after the estimate.
Ask your installer, because some foams need a covering such as a coating or drywall, either by code or because of the material, and others don't. I'll tell you before we start whether the foam going into your attic needs one, so it's planned and priced up front.
In a sealed attic, guidance calls for a direct-vent, sealed-combustion furnace or a heat pump, not a low-efficiency unit that pulls its combustion air from the attic. If yours is the older kind, I'll point it out at the estimate so you can plan that change with your heating contractor before the foam goes in.
