Insulation contractor services in Compton, CA
B&K Compton Spray Foam Insulation is an insulation contractor in Compton, CA, and we've been sealing and insulating homes since 2013. Most calls start with a hot upstairs, a drafty room or a power bill that keeps climbing, and the fix usually starts in the attic. The price turns on the size of the space, how much insulation is already up there, whether old material has to come out, and whether foam or loose fill fits the house. The schedule turns on removal, any repairs I find first and whether a permit is needed. At the estimate I look at the space and give you your own number.
Spray foam expands as it goes on, so it fills cracks and insulates in the same pass. We use it on rooflines, rim joists and odd-shaped spots where batts and loose fill leave gaps.
View serviceUpstairs bedrooms hot by afternoon? Most of that heat comes through the attic, so we seal the gaps, keep the eave vents clear and bring the insulation to an even depth from edge to edge.
View serviceBlown-in insulation is loose fill blown through a hose, and it settles into corners and around joists that batts can't reach. It's usually a lower-cost way to top up an attic that already has some insulation.
View serviceFor the whole house, I look at the attic, walls and floors together at the estimate. Then we put the work in the order that does the most good first.
View serviceInsulation that got soaked by a roof leak or filled with rodent droppings has to come out, because new material on top just buries the problem. We vacuum it out, bag it and leave the attic clean for what goes in next.
View serviceCold floors in a raised house usually mean the crawl space underneath is open to outside air. We insulate between the floor joists so the rooms above stay more comfortable.
View serviceCan you insulate walls without tearing them open? Usually yes, by blowing insulation in through small holes we patch afterward, which suits older houses built with empty wall cavities.
View serviceAir sealing means closing gaps before insulating, and we do it across the house, at doors, outlets, plumbing runs and the wall between the house and the garage. It's the step that stops drafts, and the one most often skipped.
View serviceWe insulate basement walls and the rim joist, the band of framing that sits on the foundation, so a below-grade room stops pulling heat out of the rest of the house.
View serviceClosed-cell foam is dense foam that blocks moisture as well as heat. We use it on rim joists, crawl space walls and other spots that can get damp.
View serviceOpen-cell foam is a lighter, softer spray foam that seals rooflines and walls and quiets outside noise. It costs less than closed-cell and works well where moisture isn't a concern.
View serviceFor business owners and landlords with commercial space, we insulate ceilings, walls and roof decks in offices, shops and small buildings. We plan the work around your hours so you can keep the doors open.
View serviceWe lay a heavy plastic sheet over the dirt in a crawl space so ground moisture stays down there instead of rising into the floor framing.
View serviceNeed to keep moisture out of a wall, ceiling or floor? We install a vapor barrier on the side the job calls for, so damp air doesn't condense inside the insulation.
View serviceBefore any insulation goes into an attic, we seal the gaps around can lights, pipes, wiring and the hatch. Insulation can't stop air that blows right through it.
View serviceRetrofit work adds insulation to a house that's already finished and lived in, often an older one built with little or none. We pick the route that disturbs the least, through the attic, the crawl space or small openings in the wall.

We're a Compton crew working the cities around it
Compton runs its own city services, from the permit counter at City Hall to a recreation department that keeps up sixteen city parks, including Tucker Park, Kelly Park and Jackie Robinson Baseball Stadium. The Compton Art & History Museum on W Compton Blvd puts on exhibitions, and the Compton Chamber keeps a list of historic sites like the Eagle Tree, a 60-foot sycamore at Poppy Street and Short Avenue.
Nearby Long Beach averages about 12 inches of rain spread over roughly 35 days a year, so the calls we get lean toward heat building up in the attic and the power bill climbing, more than wet ceilings. In attics around here we see thin old insulation, open gaps around lights and pipes, and now and then signs of rodents. We're based in Compton and work in the cities around it, plus the nearby unincorporated areas the county looks after, and you can read how I got into this trade.
Why homeowners call us
The owner writes your estimate
I come out, look at the job and write the estimate myself, so the person telling you what's needed is the one who answers for the work. I check the crew's install before we call it finished.
Problems found before the quote
Before I price anything, I look for roof leaks, old wiring, pests and odd materials in the space. That way repairs get sorted first, and you hear about them at the estimate, not halfway through.
A cheaper material when it works
If topping up loose fill does what you need, I'll say so, even when foam would mean a bigger ticket for us. You'll also hear what has to happen now and what can wait.

What finished insulation work looks like
Insulation questions we hear in Compton
Do I need a permit for insulation work in Compton?
It depends on the job, and I check that at the estimate. The city's Building and Safety department issues permits for alterations, repairs and improvements to existing buildings, and its permit process is handled in person, with no online submittals or payments. If your job needs one, we'll tell you and handle the paperwork with the city or county office.
Does an insulation contractor need a license to work in Compton?
In most cases, yes, from both the city and the state. Compton requires anyone doing business inside city limits to hold a city business license, renewed every year, and every permit application needs one. California's Contractors State License Board requires a contractor's license when a job needs a building permit, uses employees, or costs $1,000 or more in labor and materials together. We're licensed and fully insured.
Should old attic insulation be removed before adding new insulation?
Only if it's damaged. Insulation soaked by a roof leak or full of rodent droppings should come out, because new material on top just buries the problem. If the old layer is dry and clean, we usually leave it and add to it, and I'll tell you how many inches are already up there.
Is spray foam or blown-in insulation better for my attic?
For most attics, sealing the gaps and topping up with blown-in insulation is the better buy. Spray foam costs more because it seals air while it insulates, and it earns that cost when your ductwork runs through the attic. If the ducts are somewhere else, the extra money usually doesn't buy much more comfort.
Do I have to leave my house during spray foam insulation?
With spray foam, usually yes, for a set wait called re-entry time, which is how long before you, the kids and the pets can come back inside. That wait comes from the foam maker, and I give it to you at the estimate so you can plan. With blown-in work you can usually stay home, as long as everyone keeps out of the work area.
How long will an insulation crew be in my attic?
It depends on the size of the attic and what has to happen before new insulation goes in. Removing old material, fixing leaks or wiring, and sealing gaps all come first, and each one adds time. I'll walk you through the schedule at the estimate once I've seen the space.
How do I get my house ready for attic insulation?
Clear a path to the attic hatch and move anything stored under it or up in the attic. Keep pets in a closed room or out of the house on install day, and cover things in the garage if the hatch is there. We lay down drop cloths and clean up inside before we leave.
Can adding attic insulation cause moisture problems?
It can if the eave vents get buried, because the attic stops breathing and moisture ends up in the framing. We keep the vents open with baffles, short chutes that hold an air path clear at the edges. We also keep the coverage even right out to the walls instead of piling it up in the middle.
