Is blown-in insulation right for my attic?
Blown-in insulation is loose cellulose or fiberglass blown through a hose across your attic floor. For most Glendale houses with a vented attic, it's one of the simplest ways to help the house hold its heat in winter and its cool in summer.
Most calls I get start with a hot upstairs bedroom or a room over the garage that never feels right, and in older houses I usually find only a few inches of packed-down fill up there. The price mostly turns on the size of your attic, how much old material is already there and whether it's still clean, which material you pick, and how many gaps need attic air sealing before anything gets blown in. The schedule depends on those same things, plus whether a permit or a test has to come first. The estimate I write after looking in your attic gives you the figure for your own house.
How we install blown-in insulation
First I look at what's already up there and whether it's still clean and dry. Our crew then does the air sealing, which means closing the gaps around can lights, pipes, wires and the attic hatch so the new insulation isn't fighting a draft. Next we set baffles, short guards near the eaves, so the vents keep the attic breathing and the fill doesn't spill into them. We talk through cellulose and fiberglass with you, since each has its own strengths, and pick what fits your attic. Then we blow it in as level as we can across the whole ceiling, all the way out to the top plate where the outside walls meet the roof, because the edges are where a rushed job ends up thin. We keep it back from chimneys and flues. If I spot anything that looks like vermiculite, we stop and leave it alone until it's been tested.
If the old layer is soaked, moldy or full of droppings, blowing fresh material over it just buries the problem, so we handle the insulation removal first. If the attic is only part of what's bugging you, say cold floors over a crawl space or drafty rooms downstairs, we can look at the whole house as home insulation work and tell you where the money does the most good.
Blown-in insulation in Glendale: permits and the houses we see
The City of Glendale handles all of its permit applications through its online permit portal, and whether your insulation job needs one depends on the work and your address, so we don't assume either way. We check with the city or county building office for your address. If your job needs a permit, we pull it and line up the inspection, and we put in writing who's handling it so nothing falls through the cracks.
We're based in Glendale and work in the cities around it, from the foothills out across the San Gabriel Valley. A lot of the attics we climb into here belong to older houses, with thin old fill, can lights poking through and a hatch nobody ever sealed, and we see the same setup on jobs in Burbank and La Crescenta-Montrose. If cost is what's holding you back, the state's Department of Community Services and Development works with local service providers to install weatherization for low-income homeowners and renters who qualify under the federal Weatherization Assistance Program, so it's worth checking whether your household qualifies.

What happens when you call us about blown-in insulation?
Call and tell me what's going on
Most of the time I pick up myself. I'll ask which rooms feel off and how old the house is, then we pick a time for me to come out.
I look in your attic first
I go up with a flashlight, check what's there and how deep it is, and walk you through what I find. Then I write up the estimate, showing what needs doing, what doesn't and what it costs, so you pay only for the work your house needs.
Our crew seals and blows in
Our crew lead and installers do the work, starting with the sealing and the eave baffles before any insulation goes in. If your job needs a permit, it's already pulled and the inspection is lined up.
I come back to check
Before we pack up, I come back and look over the attic with you. We check the depth, the edges and the vents at the eaves together.

Questions about blown-in insulation in Glendale
Is cellulose or fiberglass better for blown-in attic insulation?
Each one has an edge, and the right pick depends on your attic. One insulation guide gives cellulose a slight performance edge, with better coverage around obstructions and a little air sealing of its own, while fiberglass resists settling better, doesn't burn and carries less moisture risk. At the estimate, I'll show you how that trade-off plays out in your attic.
What is the best way to prepare an attic for blown-in insulation?
Seal the gaps first, then make sure any gas furnace or water heater can still breathe. Federal energy guidance puts safety first, checking that equipment venting by gravity, meaning a natural draft up a flue, still gets enough air to burn safely once the attic is tighter. If it doesn't, the plan includes that fix or a switch to a power vent or direct vent unit before any insulation goes in.
What should I do if my attic has vermiculite insulation?
Leave it alone and don't disturb it. The EPA advises assuming vermiculite may contain asbestos and keeping it undisturbed, and it usually looks like pebbly, pour-in fill that's gray-brown or silver-gold. As I mentioned above, if I see anything like it, we stop and plan the job around testing.
How much does blown-in insulation cost in the Los Angeles area?
Installing attic insulation in the Los Angeles area usually costs about $1 to $4 per square foot. That's what the work generally runs around here, not our price, and your attic lands in that range based on its size, the old material, the sealing it needs and the material you choose. Your estimate gives you the actual figure for your house.
How do I know if my attic needs more insulation?
If upstairs runs hot, the room over the garage stays drafty or you can see the tops of the ceiling joists, it probably needs more. The age of the house tells me a lot too, and I'll measure how many inches are already up there and whether that layer is still clean and dry.
Should I get spray foam instead of blown-in insulation in my attic?
For most attics, sealing the gaps and topping up with loose fill is the better buy. Foam costs more and seals air while it insulates, so it usually earns its price when your ductwork runs through the attic. If that's your setup, we'll talk about spray foam insulation at the estimate.
Work that often goes with it
Home insulation
Home insulation helps when the cold floors and drafty rooms aren't just coming from the attic.
Insulation removal
Insulation removal clears out wet, moldy or pest-fouled material so the new layer starts on a clean attic floor.
