Request an estimate
We seal and insulate attics, walls and crawl spaces for homeowners and property managers in Alhambra, starting with whatever the house needs fixed first.
Alhambra sits in the San Gabriel Valley, and we work across the cities around it as well, such as Monterey Park and Rosemead. Most of our calls here come from homeowners with hot upstairs rooms or older houses, and some come from property managers planning a reroof or remodel who want the insulation done at the right point. The houses vary a great deal, so the first thing I do on any job is look at what's already up there before suggesting anything.
Building permits in Alhambra come from the city's Building Division, which covers most work on private property, and its list names jobs like roofing, remodeling and window replacement rather than insulation. That's why we check with the division before work begins, and you're welcome to call them yourself to ask whether your project needs a permit. The city also requires every contractor working here to hold a city business license along with a state license, which is worth asking about when you compare bids.

Insulation contractor services in Alhambra, CA
A&S Alhambra Spray Foam Insulation is an insulation contractor in Alhambra offering 16 services, from sealing a leaky attic to spraying foam under a floor. The price usually turns on how much is already up there, how many gaps need sealing, how easy the space is to reach, and whether foam or loose fill suits your house. The schedule depends mostly on whether old insulation has to come out first and whether a roof leak or a permit needs handling before we begin. I'll give you the figure for your own house in a free estimate at your property, after I've looked the space over.
Spray foam insulation
Spray foam expands into gaps as it goes on, so it seals air and insulates in one step. We spray both closed-cell and open-cell foam and choose the one that suits the space.
Attic insulation
Attic insulation is where most of our calls start, usually with a hot upstairs room or the room over the garage. We check how many inches are already up there, keep the eave vents clear and lay the new material evenly out to the edges.
Blown-in insulation
What is blown-in insulation? It's loose fill blown through a hose, which lets us reach low corners and top up an older attic without tearing anything out.
Home insulation
Not sure where your house is losing comfort? We look at the attic, walls and crawl space together and recommend an order of work that makes sense for the whole house.
Insulation removal
When old insulation was soaked or is full of droppings, laying new material over it only hides the problem. We bag it, take it out and clean the attic so the new layer starts on a sound base.
Crawl space insulation
Cold floors usually mean the crawl space under them has little or no insulation. We insulate between the floor framing under the house so the rooms above stay more even.
Wall insulation
We insulate closed walls in older houses through small openings, and open walls during a remodel, so rooms stop losing comfort through their sides.
Air sealing services
Air sealing is the work of closing gaps around pipes, wires, vents and fixtures before any insulation goes in. It's what makes a drafty house stop feeling drafty, and we do it before we insulate.
Basement insulation
Have a basement that stays cold? We insulate its walls and the band of framing where the house sits on the foundation, with materials suited to a space below ground.
Closed-cell foam insulation
Closed-cell foam is a dense foam that blocks moisture as well as air, so it suits crawl spaces and spots that may get damp. It's the firmer of the two foams, and the pricier one.
Open-cell foam insulation
Open-cell foam is softer and lighter, and it fills odd-shaped roof and wall cavities well. We use it where moisture isn't the concern but air leaks are.
Commercial insulation
We insulate offices, shops and rental buildings, and we work with property managers planning a reroof or remodel so the insulation goes in at the right point.
Crawl space vapor barrier
A crawl space vapor barrier is a heavy plastic sheet laid over the dirt under your house to keep ground moisture from rising into the framing. We overlap and seal the seams so it stays in place.
Vapor barrier installation
We install vapor barriers on walls, ceilings or floors where moisture would otherwise reach the insulation. We'll also tell you plainly where one isn't needed.
Attic air sealing
Before new insulation goes into the attic, we seal the gaps around can lights, pipes, wires and the hatch. Otherwise the insulation ends up fighting a draft and the upstairs stays hot.
Retrofit insulation
Retrofit insulation adds to a house that's already built and lived in, without a full remodel. It suits an older house that has little or nothing in its walls or attic.
What you can expect from us
We look before we quote
I check the depth of what's already in your attic, walls or crawl space, and I look for leaks, droppings and buried vents before I put anything on paper. That way the work you pay for fits your house rather than a guess.
Someone who learned the trade by hand
I started as a helper on a small insulation crew, hauling bags up ladders and learning attics from the person who ran it. I still visit most jobs myself, and I'll explain each choice in plain terms before our crew begins.
We'll tell you if the job should wait
If your roof leaks or something needs a test first, I'll say so and help you plan the order of the work. Sometimes that means a smaller job for us, and that's fine, because insulation laid over a problem only hides it.
If you'd like someone to look over your attic, send us a request or call (626) 525-0036.

(626) 525-0036Know what's up there before you plan
It helps to know how many inches of insulation are already in your attic and roughly how old the house is, because a newer, clean layer may only need sealing and topping up while an older one may need to come out first. A look through the attic hatch tells you a lot, and I'll measure it properly when I visit.

Insulation questions from Alhambra homeowners
How much does attic insulation cost in Alhambra?
It depends on the size of the attic, what's already up there and how much sealing it needs, so I give a figure only after seeing it. Removing old soaked or dirty insulation, or choosing foam over loose fill, raises the price. The estimate is free and done at your house.
How long will the insulation crew be in my attic?
That turns on the attic's size, how easy it is to reach and whether old material has to come out first. I'll tell you what to expect for your house at the estimate, before anything is scheduled.
Do I have to leave the house during spray foam insulation?
Usually yes, and you, the kids and the pets stay out until the re-entry time has passed, which is the wait before it's fine to come back inside. With air sealing and blown-in work, most families can stay home. We go over the timing for your job before we start.
How do I get my house ready for attic insulation?
Clear a path to the attic hatch and move anything stored up there or in the closet below it, so the crew can work without stepping around your things. If we're working under the house, keep the crawl space door easy to reach.
Can new insulation cause moisture problems in my attic?
It can if the eave vents get buried, because the attic stops breathing and moisture can show up in the framing. We keep those vents clear with baffles, short channels that hold the insulation back from the vents.
Is spray foam or blown-in insulation better for my attic?
Sealing the gaps and topping up with blown-in usually wins, because it costs less and does the job well in most attics. Foam earns its higher price when your ductwork runs through the attic, since it seals air while it insulates around the ducts.
Can an unlicensed handyman insulate my attic in Alhambra?
Only for minor work under $1,000, and only when the job needs no permit and the person hires no workers, according to the state's contractor licensing board. If either condition fails, a state license is required even on a job under $1,000. The city also requires every contractor working in Alhambra to hold a city business license.
Who pulls the permit for insulation work in Alhambra?
When a permit is needed, we pull it, since the city lets only properly licensed people, or owners who qualify to build for themselves, pull permits for regulated work. An owner who pulls it becomes the responsible party on the permit, and the city's own form says a licensed contractor holding it may protect you from financial risk.
