Insulation contractor in Alhambra - attics sealed before they're insulated
A&S Alhambra Spray Foam Insulation is an insulation contractor based in Alhambra, CA. We seal the gaps in attics, crawl spaces and walls, then add blown-in or spray foam insulation so older houses here hold their temperature.
Alhambra houses, as we see them from the attic
Alhambra is home for us. I opened the business here in 2021, and a good share of our work is right here in the city, in older one-story houses, two-story homes with a room over the garage, and small rental buildings. The city sits in the San Gabriel Valley between South Pasadena and San Gabriel, and the houses on either side of those lines are much like the ones here.
What shapes the work here is age. In many of these houses the insulation has settled thin, and the attic has been opened for a roof or a remodel more than once, so before anything new goes in, I look at what's already up there and how many inches are left.
Permits, licenses and pricing on Alhambra jobs
The city's Building Division issues building permits for work on private property here, and its permit list names jobs like roofing, remodeling, window replacement and heating, not insulation on its own. That office decides whether your job needs a permit, so we check with them before work begins, and when one is needed, we pull it and keep you informed through the inspections, which means the schedule depends on the city's review as well as ours. You're welcome to call the division yourself. Before you hire anyone, ask for two things: a state contractor license and a City of Alhambra business license, which every contractor working in the city needs. We're licensed and insured.
On the job itself, the price turns on the size of the attic and how easy it is to reach, whether old insulation has to come out first, how many gaps need sealing, and whether loose fill or foam suits the house. The schedule turns mostly on whether a permit is involved and what I find at the visit, and the estimate gives you your own figure along with what I'd recommend and why. We do the same work just south of here in Monterey Park, where the houses and the attics are much the same.
What we find in Alhambra attics and how we handle it
Most of our calls in Alhambra are about a hot upstairs or a drafty older house, and when I get into the attic, the cause is usually the same few things. The old insulation is deep in the middle and thin at the edges, where it's hardest to reach, and the gaps around can lights, pipes and the hatch were never sealed, so air slips straight past it. We start with air sealing, which closes those gaps, because insulation laid over a draft is fighting it the whole time. Then we keep the eave vents clear so the attic can still breathe, and we build the coverage up evenly, edges included.
Rooms over the garage and attics with ductwork in them are where I'll bring up foam. Spray foam insulation costs more, but it seals air while it insulates, which matters when the ducts live up there. For most attics here, sealing the gaps and topping up with blown-in insulation, loose fill blown through a hose, is the better use of your money.

Call or send a request
Call (626) 525-0036 or use the form, and tell us what you're noticing, such as a hot upstairs, cold floors or a reroof coming up. We'll set a time for me to come see the house.
I look the house over
I come out myself and check the attic, crawl space or walls for anything that has to be handled first, like a roof leak, droppings or buried vents. It helps if the attic hatch is clear of boxes so I can get up there.
We go over my recommendation
I explain what I'd recommend and why, and the estimate lays it out for you. If a leak should be fixed or a test arranged first, I'll tell you that before suggesting any insulation.
We check permits with the city
If the Building Division says your job needs a permit, we pull it before work begins. For projects that need plan check, a review of the plans, an undated city overview gives 2 to 4 weeks, so we set the work date around it.
Our crew installs, then we walk through
Our crew does the work with me, sealing first and insulating second. I walk through the finished job with you before we leave.
Insulation work, start to finish
Alhambra insulation questions we hear most
How much does it cost to insulate an attic in Alhambra?
The cost comes down to your attic's size, what's already up there and how much has to happen before new insulation goes in. Removing damaged material, sealing a lot of gaps or choosing spray foam over loose fill raises the price, while a clean, sealed attic that only needs a top-up costs the least. I give you the figure after I've been in the attic, because that's the only way to know.
How do I know if the old insulation in my Alhambra attic needs to come out?
It needs to come out if it's been soaked by a roof leak or is full of droppings, because new insulation laid on top keeps the problem in place. Insulation that's dry and clean but thin can usually stay and be topped up. I check this at the visit, and I'll tell you plainly which one you have.
Do I need a permit to add insulation during a reroof in Alhambra?
The roofing part does, because roofing is on the city's permit list. Insulation isn't named on that list, so whether the attic work adds anything is something we confirm with the Building Division before we start. If a reroof is coming, it makes sense to plan the attic work alongside it.
Can I pull the building permit myself as a homeowner in Alhambra?
You can if you qualify as an owner-builder under the state's exemption, but then you're the responsible party on record for the work. If anyone else works on the project, even relatives helping for free, you'd also have to carry workers' compensation for them, unless they're immediate family who live in the house. The city's own owner-builder form notes that a licensed contractor holding the permit may protect you from financial risk.
Can an unlicensed handyman do a small insulation job in Alhambra?
Only if the job is under $1,000, needs no permit and the person hires no workers. The state licensing board raised that small-job limit from $500 to $1,000, and if either of the other two conditions fails, a license is required even on a job under $1,000. Since the permit question isn't always clear for insulation, it's worth asking before you hire.
How long does spray foam insulation take in an Alhambra house, and when can we go back inside?
The time on site depends on the size of the area and the foam, and the re-entry time, when it's safe to come back in, is set by the foam maker's instructions, not by us. I tell you that time at the estimate so you can make plans for the kids and pets. Loose-fill jobs usually don't ask you to leave the house at all.
