Attics where the ductwork lives
Foam costs more, and sealing the gaps and topping up loose fill usually wins. When your ducts run through the attic, though, foam on the roof deck brings them inside the sealed space.

What open-cell foam does in your house
Open-cell foam insulation in South Whittier is a soft foam we spray into attics, walls and the room over the garage, where it expands into every gap, so one job both insulates and stops outside air from leaking in.
Most calls start with an upstairs that's hot by afternoon, a drafty back room or a power bill that won't come down. The price moves with the square footage, how deep the foam goes, whether old insulation has to come out and how hard the space is to reach, and I'll set it beside closed-cell foam so you can compare the two. The schedule turns on clearing the house while the foam cures and on whether your job needs a permit, so before work starts we check which building office covers your address and what it asks for. Your own figure comes from the estimate.
I write the estimate myself
I come out, get into the attic or look at the walls and write the estimate on site, so you know exactly what you're paying for before we start.
Attic work done in order
I started as a helper hauling bags up ladders and opened this business in 2013. We fix what's wrong underneath first, because new insulation over a leak just hides it.
Straight answers, licensed and insured
We're licensed and fully insured. If your roof needs fixing or old insulation should be tested first, I'll tell you that rather than take a job that won't hold up.
How we install open-cell spray foam
I start by looking at the space you want sealed, checking the old insulation for water stains or droppings and looking for roof leaks, because foam sprayed over a problem only hides it. Open-cell stops air well but lets moisture through, so I'm careful about where it goes, and we weigh it against closed-cell for that spot before you decide. If the old material is bad, it comes out first. On install day you're out of the house and we cover anything that isn't getting foam, and before spraying the crew checks the air temperature, the humidity and how dry the surfaces are to make sure conditions are right for the foam. We spray to an even depth, as full at the edges as in the middle, then trim and clean up. Our crew lead runs the install, and I check in on the work.
Some spots call for something else. Under the house, a damp crawl space usually needs a crawl space vapor barrier before anything else, since open-cell would let that moisture pass. Property managers and small business owners call us for offices, shops and rental units, and our commercial insulation work follows the same steps in the same order.
Where open-cell foam is the right call
The room over the garage
Cold floors in winter and heat in summer usually come from air slipping through the framing. Foam fills those odd gaps and insulates in the same pass, so the room stops lagging behind.
Walls opened for a remodel
Open studs are the easiest time to spray. Foam in finished walls means cutting out drywall sections or drilling holes to reach the cavities, which adds labor and shows up in the price.
Interior walls for sound
Open-cell is soft and spongy, so it dulls noise between rooms, like a bedroom next to the laundry or a home office by the TV. We'd usually spray it while the walls are open.

Send the form and we'll get back to you within one business day to set a time. I come out, look at the job and write a free estimate on site, with no obligation.
Which areas you want insulated
Tell us if it's the attic, the room over the garage, certain walls or the crawl space, so I know what to look at and can check each spot when I come out.
Whether the walls are finished
Finished walls change the work and the price, so let us know if the drywall is up or the studs are still open from a remodel.
Anyone with asthma or allergies
If someone at home has asthma, allergies or a skin condition, mention it up front so we can talk through foam and other options before you decide.

Open-cell foam questions from South Whittier homeowners
Here's what people ask before booking open-cell foam, from what it costs to how long you'll be out of the house.
How much does open-cell spray foam insulation cost in South Whittier?
Open-cell spray foam usually costs about $1.50 to $3.50 per square foot installed across the US, so treat that as the market's range, not our price. Your number comes from measuring your attic or walls and seeing what has to happen first, so I work it out on site and put it in writing before we start.
How long do we have to stay out of the house after spray foam insulation?
Federal guidance says everyone should leave while the foam is sprayed and stay out for at least 24 hours. Coming back waits until the foam has cured, or set, and the house has been aired out and cleaned, so plan for the kids and pets too. Ask us about the timing for the specific product we'd use.
Should I choose open-cell or closed-cell spray foam for my house?
Pick open-cell where stopping air is the main job and closed-cell where a spot also has to slow moisture. Open-cell runs about R-3.6 per inch, the measure of how well it slows heat, and lets water vapor pass. Closed-cell is rigid, about R-6 per inch, and slows vapor, so it packs more into less depth.
Is spray foam insulation safe if someone in my house has asthma?
It's something to settle before you choose foam. Federal guidance asks people with asthma, respiratory allergies, skin conditions or a past reaction to isocyanates to review the product information carefully, and points them to other insulation if needed. It also asks homeowners to go over safety steps with their contractor, and we're licensed and fully insured and glad to do that at the estimate.
Who handles building permits for insulation work in South Whittier?
The county's Public Works South Whittier District Office processes building permits here, though its list names putting up, remodeling, tearing down or moving buildings, not foam insulation, so that's the office to ask. When a job needs a permit, we handle the paperwork and line up the inspections. On the contractor side, California's licensing board has a C-2 class for installing insulation for heat or sound control.
Do California energy rules apply when I add foam to an existing attic?
Yes, the state's energy standards have a section for adding insulation to existing attics. The rules for a house's outer shell also depend on which climate zone the house sits in, so what's required can differ by address. We're based in South Whittier and work in the cities around it, and if yours isn't on the site, call and ask.
