Air sealing for attics, floors and walls

  • Attic floor sealing

    We close the openings between your attic and the rooms below, which suits any house that feels hot upstairs or is about to get new attic insulation.

  • Caulk and foam for gaps

    Caulk suits narrow cracks around trim and frames, and foam fills the wider holes where pipes, ducts and wires pass through, so each gap gets what holds best.

Do I need air sealing, or just more insulation?

Air sealing services in Bell close the gaps in your ceiling, walls and floors that let drafts and hot attic air into your rooms. Think of insulation as a sweater and sealing as the windbreaker over it, and most houses need both.

Most calls start with a hot room upstairs, a drafty hallway or a power bill that won't come down, and the cause is usually air slipping through gaps you can't see from inside. The price turns on how many leaks we find and how hard they are to reach, and the schedule turns on that same access and on whether attic insulation is coming next, so the two can be lined up. Your written estimate gives you the price for your house.

Air sealing, prep and what goes on top

What your house needs depends on what's up there and what comes next. If attic insulation is on your list, I'll tell you to seal first, since covered leaks stay buried until the insulation comes out.

  • The easy leaks are yours

    You can caulk the obvious leaks around door frames yourself, and our crew takes the small hidden ones, especially attic gaps buried under insulation.

  • Fixing what comes first

    We check for roof leaks, wet or soiled insulation and anything that needs fixing first, since sealing over a problem just hides it.

  • Clearing the attic floor

    We pull old insulation back to reach the attic floor, then seal around can lights, pipes, wires and the hatch with caulk or foam.

  • Sealing below the floors

    We seal where pipes and wires come up through the floor, and if you're also doing basement insulation, we line the two jobs up.

  • What goes on top

    Loose fill usually wins, but with ducts up there, closed-cell foam insulation earns its higher price, since the dense foam seals as it insulates.

Why Bell homeowners pick us for sealing and insulation

    We're licensed and insured. I want my crew working safe up there and your house left clean, so we cover the floor under the hatch and haul off what we pull out.

Questions Bell homeowners ask about air sealing

How much does air sealing cost in Bell, CA?

We price air sealing house by house, and you get the number in writing after I look at your space. The biggest swings come from old insulation that's soaked or full of droppings, since it has to come out before anything new goes in, and from whether loose fill or foam goes on top afterward.

Is air sealing safe if my house has a gas water heater or furnace?

It can be, with a test before and after the work. In some cases, sealing can make a gas or oil appliance that vents naturally pull its exhaust back into the house, so ENERGY STAR suggests having a Home Performance Contractor check how those appliances draft before and after sealing. Tell us about your water heater or furnace when you call, and we'll plan the sealing around that testing.

How do I find air leaks in my house that I can't see?

Small hidden leaks usually take a certified home energy assessor, who uses a blower door, a fan that pulls air out of the house so leaks show up, and an infrared camera that shows warm and cold spots. When I come out, I start where leaks usually hide, on the attic floor around anything that runs through the ceiling.

How long does air sealing take, and do we have to leave the house?

You can usually stay home, because most sealing is caulk and foam work up in the attic. How long we're there depends on the attic's size and how much old insulation has to be moved, and I'll go over that at the estimate. If a job calls for spray foam, I'll tell you the re-entry time, when the kids and pets can come back in, before we start.

What causes a hot room upstairs or over the garage?

Usually it's hot attic air leaking into the room through gaps in the ceiling, plus insulation that's thin where it counts. On older houses we often find insulation piled deep in the middle of the attic and thin at the edges, which is backward, so sealing the gaps and evening out the coverage usually helps.

Can air sealing cause moisture problems in my attic?

It shouldn't, as long as the attic can still breathe, because sealing the ceiling keeps damp house air from getting up there in the first place. The trouble usually comes from burying the eave vents, the openings along the roof edge that let air move through the attic, so we keep those clear when insulation goes back down.

What Bell rules mean for your air sealing job

Most houses in California have vented attics, and state energy code guidance says the state's attic insulation and air sealing requirements for vented attics apply when the ceiling above your living space is altered, which includes adding or replacing attic insulation or putting in a whole new duct system up there. For what applies to your Bell job now, the city's Building and Safety Division issues permits, and you can call (323) 588-6211, extension 2611, to find out whether you need one. Permit rules aren't the same in Bell, the other cities and the county areas, so we check with the office for your address before we start, and if your job needs a permit, we handle pulling it.

We're based in Bell and work in the cities around it, along with county areas like East Los Angeles and Walnut Park. A lot of the houses we see are older, with ceilings cut and patched for wiring and lights over the years, so we go in expecting more hidden gaps than a newer house would have.
