Insulation Contractor in West Covina - Attics Sealed First, Then Insulated
A&S Alhambra Spray Foam Insulation is an insulation contractor based in Alhambra, CA, and we work in West Covina too, sealing attic gaps, clearing out old or dirty insulation, and adding blown-in, foam and wall insulation.
How West Covina's houses shape an insulation job
West Covina sits in the San Gabriel Valley, east of us in Alhambra, and most of what we see on jobs here is homes. Single-story ranch houses line the flatter streets, and newer two-story houses climb the San Jose Hills on the north side of the city. Interstate 10 runs through with the big shopping centers along it, but a block or two off the freeway it's neighborhoods again, much like the ones we work in over in El Monte.
On a single-story house the attic is low and runs over every room, so one tired attic shows up in the whole house. On the hillside two-story homes, the room over the garage is usually the first to heat up.
What to know before insulation work starts in West Covina
When an insulation job here needs a permit, it comes from the Building Section of the city's Building Division, which issues permits for all private work in West Covina. So before we start, I check with the division, and if a permit is needed we pull it and keep you informed through the inspections, which is the one part of the schedule we don't set. The city also requires every business operating in West Covina to hold a city business license, so that's a fair thing to ask any contractor about. We're licensed and insured.
The price turns mostly on what's already up there, because insulation that has to come out costs more to deal with than a top-up. How many gaps need sealing, whether the ductwork runs through the attic, and how easy the hatch is to reach move it too. The schedule depends on removal and on whether an inspection is involved, and I explain what I'd recommend for your house and why in the estimate. It's the same careful attic work we do across the valley and over in Glendale.
Why West Covina homes call us about the heat
Summer afternoons out here run hot, and an attic with a few thin inches of old insulation passes that heat straight into the bedrooms, which is why most calls start with "it's hot upstairs" or the room over the garage. We seal the gaps around can lights, pipes and the hatch first, then bring the coverage up evenly out to the edges, where it's usually thinnest, while keeping the eave vents clear so the attic can still breathe.
Older houses often have walls with little or nothing in them, so a room can stay drafty after the attic is done. For those we look at wall insulation blown into the cavities, but usually after the attic, since that's where the heat gets in first.

(626) 525-0036How it goes when you call us from West Covina
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, a drafty room or a high power bill. If you know roughly how old the house is, that helps me plan the visit.
I look over your attic
I come out myself and check how many inches are up there, whether it's wet or full of droppings, and whether the eave vents are clear. It helps if the hatch is easy to reach, so clearing a closet shelf beforehand saves time.
Go over what I recommend
I explain what I'd do and why, including anything that should be fixed first, like a roof leak. If foam doesn't suit your house, I'll tell you so rather than sell it.
Check permits with the city
Before work begins I check with the Building Division, and if a permit is needed we pull it. Its counter takes applications in person Monday through Thursday, 7:30 am to 5:30 pm, which shapes when the paperwork moves.
Install, then walk through together
Our crew does the work with me, sealing the gaps before any new insulation goes down. Before we leave, I walk through the finished job with you.

West Covina insulation questions
Do I need a permit for insulation work in West Covina?
The Building Division decides, because the city's list of work that needs no building permit covers sheds, fences, decks and finish work like painting and carpeting but doesn't mention insulation. We check with the division before we start, and you can call it yourself at (626) 939-8425.
How do I apply for a building permit in West Covina?
You apply through the city's One Stop Building Permit Center or in person at the Building Counter, Monday through Thursday, 7:30 am to 5:30 pm, since the Building Division no longer takes applications by email. When your insulation job needs a permit, we pull it ourselves and keep you informed through the inspections.
Does an insulation contractor need a business license to work in West Covina?
Yes, the city requires every business operating in West Covina to get a city business license, due within fifteen days of starting business there. The Finance Department handles business licensing, so it's reasonable to ask a contractor about it before you hire.
How much does attic insulation cost in West Covina?
Your price comes from what's in your attic now, because pulling out soaked or dirty insulation, sealing a lot of gaps or choosing foam all cost more than topping up clean loose fill. Foam costs more and seals air while it insulates, but sealing the gaps and adding blown-in, which is loose fill blown through a hose, usually wins unless your ductwork runs through the attic. The estimate after my visit puts a price on your own house.
How long do we have to stay out of the house after spray foam insulation?
Everyone, kids and pets included, stays out until the foam's re-entry time has passed, which is when it's safe to come back inside, while with blown-in insulation you can usually stay home. The foam's maker sets that time, so I tell you what it is for the product we're using before the work day.
What is the best way to insulate an attic that already has old insulation?
If the old insulation is dry and clean, we usually seal the gaps and add to it, but if it's soaked or full of droppings it has to come out first, because new material laid over it keeps the problem. I check which it is during my visit, and I'll ask you to have any roof leak fixed before we put anything new down.
