Insulation Contractor in Norwalk, CA - Attics Sealed First, Then Insulated
B&K Compton Spray Foam Insulation is an insulation contractor working in Norwalk, CA. We seal and insulate attics, walls and crawl spaces, clear out old or dirty insulation, and install spray foam where the house calls for it.
What we find in Norwalk attics and crawl spaces
Norwalk is a short drive from us in Compton. Most of our calls there come from people in single-family houses, plus landlords with rentals and a few business owners. A lot of what we get into is older housing with low attics, where the ductwork runs through the space and the insulation has had years to settle and thin out.
It's the same kind of work we do next door in Downey, so we know where to look. A low attic means tight crawling and ducts and wiring in the way, and the old material may have to come out before anything new goes in. That decides how we plan the job.
Before your Norwalk insulation job starts
If your Norwalk job needs a permit, I'll tell you at the estimate, and we handle the paperwork with the city or county office so you aren't the one chasing it. Before you hire anyone, ask for their state contractor license, because California requires one for most insulation jobs, and the license question further down spells out when. We're licensed and fully insured, and I'm glad to show you.
Price and timing turn on what's up there now. Whether old insulation has to come out, how many gaps need sealing, how tight the attic is to work in and which material fits your house all move the number. Any repair that has to come before the insulation moves the schedule. I put the figure for your house in writing after I've seen it, and I work it out the same way whether you're in Norwalk or West Rancho Dominguez.

Ducts in the attic change what we recommend
A lot of the houses we see in Norwalk have their ductwork running through the attic, and that's the one case where I'll usually point you toward spray foam. Foam costs more, but it seals air while it insulates, so the ducts sit in a space that stays closer to the temperature of the rest of the house. When the ducts aren't up there, air sealing, closing the gaps before any insulation goes in, followed by a top-up of blown-in, loose fill blown through a hose, usually gets you most of the way for less money.
Cold floors usually start underneath the house. On raised floors we insulate the crawl space and lay a vapor barrier where the ground stays damp, and if you've got a room below grade we handle that with basement insulation.

Norwalk insulation questions we hear most
How much does it cost to insulate an attic in Norwalk, CA?
The price comes from what's in your attic now, so you get a written number after I've looked at it. Clean insulation that's just gone thin usually costs the least to fix, because we seal the gaps and top it up. Hauling out dirty material, foaming around ductwork or working in a very low attic adds to it. Call (562) 232-8636 to set up the visit.
Does an insulation contractor in Norwalk need a California license?
Yes, for most insulation jobs. The Contractors State License Board rules require a current state license for anyone contracting on work that needs a building permit, uses employees or workers, or comes to $1,000 or more in labor and materials combined. We're licensed and fully insured, and you can ask me for the license details at the estimate.
Can someone without a license do a small insulation job in Norwalk?
Only if the whole job comes to less than $1,000 in labor, materials and every other cost, needs no permit and uses no employees, and the person doesn't advertise as licensed. That limit used to be $500 before it went up to $1,000. Owners who work on their own house themselves, or with their own employees paid in wages, may be exempt as owner-builders, as the board puts it.
How do I know if my old attic insulation needs to come out?
It usually has to come out if it's been soaked, smells, or is full of droppings, because new material laid on top just traps the problem up there. Insulation that's clean but thin can usually stay and get topped up. I check it on the estimate visit and tell you which one you've got.
How long does attic insulation take, and when can we come back inside?
I give you the timing for your house at the estimate, because it turns on the material and how much prep the attic needs. With blown-in work you can usually stay home. Spray foam has a re-entry time, a wait before people and pets can come back in, and I tell you what it is before we start so you can plan for the kids and pets.
What causes the upstairs or the room over the garage to stay hot in Norwalk?
Usually it's air leaking through gaps around can lights, pipes and the attic hatch, plus insulation that's thin at the edges where it should be deepest. Eave vents buried under insulation make it worse, because the attic can't breathe and moisture builds up in the framing. We seal the gaps, keep the vents clear and build up the edges before we call it done.
