Open-cell foam for these kinds of attics

  • Attics with ducts running through

    We spray the underside of the roof deck and close off the vents, so the attic becomes part of the heated and cooled house. It suits attics with ducts.

  • Attics that are hard to vent or seal

    Some attics have little room for vents, or a ceiling full of gaps that's hard to seal from above. Foam at the roofline sidesteps both problems.

Is open-cell spray foam right for my attic in Bell?

Open-cell foam insulation in Bell, CA is sprayed onto the underside of your roof deck, which seals the attic and makes it part of the heated and cooled space of your house, so the ducts up there stop sitting in summer heat.

Most calls start with a hot upstairs or a room over the garage that never cools down, while the AC pushes air through ducts in a baking attic. The price moves with how much roof surface we're covering, whether old insulation has to come out, any roof repair that has to happen first and whether the foam needs a cover over it. The schedule turns on that same roof work, on any permit your address needs and on the time your family spends out of the house while the foam goes in. You'll get your own price in writing after I've seen the space.

Open-cell foam, from roof check to final cover

I decide what your job needs by looking at your ducts, your roof and how you'll use the attic, and if open cell isn't a fit, I'll tell you.

  • Roof leaks fixed first

    Any roof leak gets fixed and the damage repaired before we spray, because foam over a wet deck just hides the problem.

  • A plan for moisture

    Closing off the vents means moisture needs another way out, so before we start we go over how your sealed attic will handle it.

  • Crawl space checked too

    If the crawl space is damp, a crawl space vapor barrier can keep ground moisture from rising into the house we're sealing up.

  • Old insulation cleared out

    If the old insulation on the attic floor is soaked or full of droppings, we pull it out so the problem doesn't stay behind.

  • Foam sprayed to the edges

    Our installers spray the roof deck out to the edges, where thin spots hide, and building owners get the same work through commercial insulation.

  • Covered where it's required

    When the foam's maker or the code calls for it, a fire-resistant cover such as a coating or drywall goes over the foam.

Why Bell calls us for prep and foam

Questions about open-cell foam in Bell

Should I seal my attic with spray foam instead of adding loose fill?

Seal it with foam if the attic holds ductwork, will be lived in, is hard to vent or sits over a ceiling that's hard to seal, because national guidance on sealed attics points to those cases. Foam costs more, but it seals air while it insulates. If none of those fit your house, sealing the gaps and topping up the loose fill on the attic floor usually wins, and I'll tell you that at the estimate.

How long does it take before we can go back inside after spray foam?

Some foam makers recommend waiting 24 hours after professional spray foam goes on before anyone goes back in, though the time can vary by product. We'll give you the re-entry time, which is when it's okay to come back, for the exact foam we're using, so you can plan where the kids and pets stay.

How much does spray foam insulation cost in Los Angeles?

Spray foam insulation in Los Angeles usually costs about $2 to $5 per square foot. That's the going rate around the area, not our price, and where your attic lands depends on its size and the prep it needs first. I'll give you your own number in writing after I've seen the space.

What are the health risks of spray foam insulation for my family?

The EPA says exposure to spray foam chemicals can cause asthma, lung damage, other breathing problems, and skin and eye irritation. That's why the household stays out while we spray and through the maker's wait afterward, and we plan that timing with you ahead of time.

How do I handle plumbing or electrical repairs in an attic with spray foam?

Tell whoever does the work that the attic has spray foam, because the EPA advises plumbers, electricians and other repair workers not to heat or grind it, since that can give off toxic emissions. It matters most for anyone soldering pipes or cutting into the roofline, so mention it before they start.

Do California energy rules affect spray foam insulation in Bell?

They can, because the California Energy Commission says several efficiency standards, including the ones for the materials that make up your home's outer shell, depend on the building's climate zone. You can look up your zone with the Energy Commission's climate zone tool, and it's one of the things we ask about when we check with the office for your address.
