Blown-in insulation we put in attics

  • Loose-fill fiberglass

    Light, fluffy glass fiber that doesn't soak up water, and our usual pick for topping up an attic that already has some insulation in it.

  • Blown cellulose

    Shredded paper treated to resist fire, blown in thick so it works into corners and around wiring, which suits attics with a lot of framing in the way.

Is blown-in insulation the right fix for my attic in Bell?

Blown-in insulation is loose fill blown through a hose across your attic floor once the gaps in the ceiling are sealed, and in Bell it's usually the simplest way to keep summer heat from coming down through the ceiling.

If the rooms upstairs run hot, the room over the garage never cools off or the power bill keeps climbing, the attic is usually where that heat gets in. Older federal energy guidance found that blowing loose fiberglass, rock wool or cellulose usually costs less than laying batts and covers better, though every job gets priced on its own. Your price moves with the size of the attic, how many inches are already up there, how hard it is to get into and whether it needs attic air sealing, repairs or old material pulled out first. Those same things set the schedule, because a wet spot or gray, flaky fill gets sorted before any new fill goes in, and I'll put your own price in writing after I've seen the attic.

Sealing, baffles and blown-in fill, in order

I go up and look before I quote, because the attic decides the job, and sometimes the right answer is a wider home insulation plan, not fill alone.

  • Check the old layer

    Blown fill can usually go over old batts, so I check how they're holding up, and if they're ruined, insulation removal comes first.

  • Seal the gaps

    We close the gaps around pipes, wires and the attic hatch first, so the new insulation isn't fighting a draft from below.

  • Keep the eave vents open

    Baffles at the eaves hold an air gap under the roof deck, so the attic keeps breathing and wind can't blow the fill around.

  • Blow it even, then clean up

    We blow the edges as deep as the middle, since the edges are where attics usually come up thin, then clean up after ourselves.

Why Bell homeowners trust us with attic insulation

We do the prep and sealing before any fill goes in, because insulation over open gaps is money thrown away. I'll tell you straight what your attic needs and what can wait, and if it isn't ready, I'd rather say so than take your money.

Questions Bell homeowners ask us

How much does blown-in insulation cost in Bell, CA?

Around Los Angeles, insulation work usually runs about $1,500 to $5,500 a job, and that range covers every kind of insulation job, not blown-in alone. Your attic's price depends on what I find up there, and you get it in writing after I come out and look.

What should be fixed in the attic before blowing in insulation?

Wet insulation from a leaky roof, moldy or rotted framing and vents that blow moist air into the attic all need fixing before new insulation goes in. National energy guidance recommends a pro handle those, and its list adds an attic with little or no ventilation and old knob and tube wiring, which is a fire hazard next to insulation. I'll tell you which of these I find, and the new fill waits until they're fixed.

How do I know if the gray, flaky insulation in my attic is vermiculite?

If it's light, gray, flaky and about the size of a pea, it's likely vermiculite, and it may contain asbestos. The only way to know is a test by an approved lab, and it should be left alone until that test comes back with no asbestos. When I see it, we stop and get it tested before anybody touches it.

Can blown-in insulation go over recessed can lights?

Not unless the fixture is rated IC, short for insulated ceiling, which tells you it's made to have insulation against it. Every other can light needs the insulation kept clear of it, so I check each fixture during the estimate and tell you which ones need attention.

What is the best way to insulate an attic in Bell, blown-in or spray foam?

For most attics here, sealing the gaps and topping up with blown fill is the better buy. Spray foam costs more but seals air while it insulates, so it earns its price when your ductwork runs through the attic, and if that's your house, I'll lay out both options.

Is it safe to air seal an attic if I have a gas furnace or water heater?

It can be, but sealing can sometimes cause a gas appliance that vents on its own draft to send exhaust back into the house, which is unsafe. That's why it's worth asking how those appliances get checked after sealing, so tell me what you've got when I come out and I'll go over it with you before we seal anything.

Permits and licensing for blown-in insulation in Bell

Permit rules in Bell aren't the same as in the cities next door or the county areas, so we check with the office for your address before we start, and if your job needs a permit, we pull it. In Bell that's the city's building permits office, and you can call (323) 588-6211, extension 2611, to ask whether a job like yours needs one. Once the city has the application, its Building Technician gets back to us with the fees and next steps. The state licenses insulation work under its own classification, which you can look up with the Contractors State License Board, and someone without a license can only take a job under $1,000 that needs no permit and only if they have no one working for them.

Around Bell we mostly see older houses with tight attics, a thin, settled layer of old insulation and a hatch tucked in a closet or hallway, so getting the hose in and keeping things clean takes some planning. We see the same kind of attics on jobs in East Los Angeles and Walnut Park, and since those are county areas, we check permits there with the county instead of Bell.
