Attic insulation we install in Bell

  • Blown-in loose fill

    Loose fiber blown through a hose onto the attic floor, filling around joists, wires and odd corners. It's usually the best value for a vented attic.

  • Fiberglass batts

    Precut blankets laid between the joists. They suit an open attic with even spacing and easy room to work, and they cost less than foam.

  • Spray foam under the roof

    Foam sprayed under the roof deck seals air while it insulates. It costs more, so I mostly suggest it when your ductwork runs through the attic.

What's involved in insulating an attic in Bell?

Attic insulation in Bell means air sealing first, closing the gaps in your attic floor where house air leaks through, then adding insulation on top, and together those two steps can do more for comfort and the power bill than any other insulation job.

Most calls start with a hot upstairs, a room over the garage you can't keep cool or a power bill that keeps climbing. The price moves with the size of the attic, how many inches are already up there, how much sealing the floor needs and whether the old layer has to come out first through insulation removal. The schedule turns on any repairs the attic needs before it's ready and on how much is stored up there to move. I'll see all of that at your place and give you the price in writing.

Attic sealing and insulation, start to finish

For a vented attic I usually point people to lower-cost loose fill or batts, and I'll tell you straight if the attic needs repairs before it's ready.

  • Look at what's up there

    We plan around whatever's stored in the attic and check the old insulation, because new material over a soaked or dirty layer keeps the problem.

  • Seal the gaps first

    We close the gaps around can lights, pipes, wires and the hatch before anything goes down, since insulation can't stop a draft blowing through it.

  • Keep the eave vents open

    We set baffles, simple guards that hold insulation back, at the eaves so the vents stay open and the attic keeps breathing.

  • Even depth to the edges

    We lay blown-in insulation or batts full depth out to the edges, where crews often leave it thin, not just piled in the middle.

  • Clean up, then the rest

    We clean up, and if the walls or crawl space need work too, we can look at home insulation for the whole house.

Attic sealing and insulation, in the right order

I started this business in Bell in 2020 after years on insulation crews around Los Angeles. I'd rather tell you an attic isn't ready than take your money for insulation laid over open gaps or a wet floor.

  • I check the work before we finish

    Our installers do the work, and I go up and look it over myself before we wrap up, so a thin edge or a buried vent gets caught while we're still there.

  • Safe crew, clean house

    We're licensed and insured. I want my crew working safe in your attic and your house left clean when we pack up and go.

  • Told straight what can wait

    I'll tell you what has to be fixed now and what can wait, and I won't sell you foam your attic doesn't need. Your satisfaction, guaranteed. Call (213) 329-1866 to set up a visit.

What happens after you call about your attic?

We plan each attic job around your house, what's stored up there and any repairs that have to come first, so our crew shows up when the space is ready.

Attic insulation questions from Bell

How much does attic insulation cost in Bell, CA?

Blown-in insulation in the Los Angeles area usually runs about $1,600 to $3,600 a job, and that's the going rate around here, not our quote. Where your attic lands depends on its size, what's already up there and how much sealing and cleanup it needs. I'll give you your own number in writing at the estimate.

What is the best insulation for a vented attic?

For the floor of a vented attic, loose-fill fiber blown in or fiberglass batts are usually the right choice, since they're the least expensive types and work well there. That's where I point most people, because it keeps the budget down without cutting corners.

How do I know if my attic is ready for new insulation?

Your attic isn't ready if the roof leaks, if there's live knob-and-tube wiring, the early kind strung on porcelain knobs, or if an exhaust fan blows into the attic instead of outside. The guidance is to fix the roof, replace the wiring for fire safety or vent the fan outdoors first, then seal and insulate. Recessed lights that aren't rated to be covered also need insulation kept at least 3 inches back on every side, so tell us how many you have.

Who is allowed to install insulation in California?

In California, the Contractors State License Board sets a C-2 class for contractors who install insulation to control heat or sound. Someone without a license can only take small jobs within a $1,000 limit, and only when the work needs no permit and they have no employees. If you're unsure what your job falls under, ask me at the estimate.

What should I do if my attic has old vermiculite insulation?

Have it tested before anyone seals or insulates the attic, because older vermiculite, the pebbly gray-brown loose fill, can contain asbestos. The guidance calls for professional advice and points owners to their state department of health. We leave it alone until it's been tested.

Do I have to leave the house when you insulate the attic?

With loose fill or batts, most people stay home while we work, though we ask you to keep kids and pets away from the hatch and the work area. Foam is different, because the foam maker sets a re-entry time, how long before you can come back inside, and I'll tell you what it is before the day.

Attic insulation in Bell and the cities around it

The City of Bell requires building permits for a long list of projects, from new buildings to fences, fireplaces and signs, but attic insulation isn't on that list, so the list alone doesn't tell you whether your job needs one. Permit rules also change between Bell, the cities around it and county areas like East Los Angeles and Walnut Park, so we check with the office for your address before we start, and if your job needs a permit, we pull it. If you'd like to ask the city yourself, its building permit page lists (323) 588-6211 for project questions.

Most houses we work on around Bell are older, with low attics reached through a small hatch, a few inches of old insulation that's settled or been chewed through, and years of boxes stored on top. Moving those things and dealing with the old layer are often part of the job here.
