Spray foam insulation
Foam sprayed under the roof or into open walls, sealing air and insulating in one pass. It costs more, and it earns that when your ducts run through a hot attic.
Insulation contractor in West Covina, CA - attics sealed before they're filled
South Whittier Insulation and Spray Foam insulates attics, walls and crawl spaces in West Covina, CA. We seal the gaps first, pull worn insulation when it has to go, then add blown-in or spray foam so rooms stay comfortable.
How we handle insulation jobs in West Covina
West Covina sits in the San Gabriel Valley, and our jobs there run from flat-street neighborhoods near the I-10 to homes up in the hills, plus some shops and offices along the freeway. We're an insulation contractor based in South Whittier, CA, and we do the same work in El Monte and Whittier. What moves the price and the schedule is what I find in your attic: how many inches are already down, whether old insulation has to come out, how many gaps need sealing first, and how easy the space is to get into. The estimate tells you what you'd pay before anything starts.
Inland summer heat builds up under these roofs, so the first call is usually about a hot upstairs or the room over the garage, and on a lot of houses here the ductwork runs right through that heat, which changes what we'd put up there.
I write the estimate myself
I come out, measure what's in the attic and write the estimate myself. Our crew lead runs the install and I check in, so the job matches what I priced.
Gaps sealed before anything new
We close the gaps around can lights, pipes and the attic hatch before new insulation goes down, because insulation laid over a draft just sits in moving air and does far less.
Permit question checked first
Before work starts, we check which building office covers your address and what it asks for. When your job needs a permit, we handle the paperwork and line up the inspections.
Insulation work we do in West Covina homes
Attic insulation
Most calls here start with a hot upstairs. We measure the inches already down, seal the gaps, then build the depth back up evenly, out to the edges where it usually runs thin.
Blown-in insulation
Loose fill blown through a hose across the attic floor. It tops up thin coverage quickly, and we keep it off the eave vents so the attic can still breathe.
Home insulation
A look at the whole house, attic, walls and floors, when one room runs hot and another feels drafty. We start where the most heat gets in and work from there.
Insulation removal
Old insulation that's soaked, flattened or full of droppings comes out before anything new goes in. Laying fresh material over it only hides the problem, so we vacuum it out first.
Crawl space insulation
For houses with a crawl space, insulation between the floor joists takes the chill off cold floors. We check for moisture down there first so the new material stays dry.
Wall insulation
Exterior walls with little or nothing in them can be filled from outside or inside, depending on the siding and the finish. We'll tell you which way makes sense for your house.
Air sealing services
Closing the leaks around the rest of the house, like pipe and wire holes, crawl space openings and the spot where the framing meets the foundation, so outside air stops getting in.
Basement insulation
When a house has a basement, we insulate its walls and the framing along the top of the foundation so the space below stops pulling heat out of the floors above.
Closed-cell foam insulation
Closed-cell foam is dense foam that blocks moisture as well as heat, so we use it where water is a risk, like crawl spaces, foundation edges and tight roof spaces.
Open-cell foam insulation
A lighter, softer foam that fills odd-shaped cavities and quiets outside noise. It fits well under the roof deck of an attic that holds ductwork and stays dry.
Commercial insulation
Insulation and air sealing for shops, offices and small commercial buildings, planned around your business hours where we can so the work stays out of your customers' way.
Crawl space vapor barrier
Heavy plastic laid over the dirt in a crawl space to keep ground moisture from rising into the floor framing and the insulation above it.
Vapor barrier installation
A moisture layer in walls, floors or ceilings, put on the right side so it keeps water vapor out of the framing instead of trapping it there. The side matters more than the material.
Attic air sealing
We go through the attic before new insulation goes down and seal around can lights, flues, wiring holes and the hatch, because insulation doesn't stop air that's moving through it.
Retrofit insulation
Adding insulation to a finished house without tearing it apart, through small openings in the walls or from the attic. It suits older homes built when nobody insulated much.

If your roof leaks or the old insulation should be tested first, I'll tell you to get that done rather than take a job that won't hold up.

Insulation questions from West Covina homeowners
These are the questions West Covina homeowners ask me most before an insulation job, answered the way I'd answer them on site.
Do I need a permit to insulate my attic in West Covina?
Check with the city's Building Division, because its list of work that skips a building permit covers sheds, fences, decks and finish work, not insulation. The division issues permits for private work across West Covina and takes questions at (626) 939-8425. We check this before we start and handle the paperwork when your job needs a permit.
How much does attic insulation cost in West Covina?
I can't give you a fair number until I've seen your attic, and the estimate gives you one before anything starts. The biggest choice is the material. Foam costs more and seals air while it insulates, but sealing the gaps and topping up blown-in usually gets you there for less, unless your ductwork lives in the attic.
Do we have to leave the house during spray foam or blown-in insulation?
For blown-in, usually not, because the work stays up in the attic and you can go about your day. Spray foam is different, and everyone, kids and pets included, stays out until the re-entry time has passed, which is the wait before it's safe to come back inside. I'll tell you the hours for your job at the estimate.
Does an insulation contractor need a business license to work in West Covina?
Yes. The city requires any business operating in West Covina, from a sole proprietor to a corporation, to get a city business license, due within fifteen days of starting business there. The city's Finance Department handles business licensing.
