Spray foam insulation
Foam seals air while it insulates, so it suits attics where the ductwork runs. It costs more than loose fill, and I'll tell you when it isn't worth it.
Insulation contractor in Anaheim - attics sealed before they're filled
South Whittier Insulation and Spray Foam is an insulation contractor working in Anaheim, CA. We seal the gaps in your attic, clear out worn insulation when it has to go, and add blown-in or foam so your rooms stay comfortable.
How we handle insulation jobs in Anaheim
We're based in South Whittier and come into Anaheim the same way we head out to Fullerton and Santa Fe Springs. Most calls here start the same way: a hot upstairs, a room over the garage that won't cool down, or an attic full of flat, dusty insulation from years back. The price moves with how much old material has to come out, how many gaps need sealing, how big the attic is and whether you go with blown-in or foam. The schedule turns on removal, any roof repair that has to come first and whether the city asks for a permit. The on-site estimate puts your own figure on all of it.
Most of Anaheim's rain falls in winter and summers are close to dry, so a slow roof leak can soak insulation for a season before anyone notices. That's why we look for stains and matted spots before anything new goes down, and why I'll send you to a roofer first if we find a leak.
The owner comes out
I come out to look at the job and write the estimate myself. Our crew lead runs the install and I check in on the work, so the person who priced it stays involved.
Gaps sealed before insulation
We close the gaps around can lights, pipes and the attic hatch first, because insulation laid over a draft just fights that draft all year.
Full coverage out to the eaves
We keep the edges as deep as the middle and leave the eave vents open, since a buried vent stops the attic from breathing and moisture shows up in the framing.
Insulation services we offer in Anaheim
Attic insulation
Most Anaheim calls start in the attic with a hot upstairs. We measure the inches already up there, seal the gaps, then build coverage evenly out to the edges.
Blown-in insulation
Blown-in is loose fill sent through a hose, and it's the usual way to top up a thin attic. We keep it full at the eaves without burying the vents.
Home insulation
When several rooms run hot or drafty, we look at the attic, walls and floors together and tell you which spot to fix first and why.
Insulation removal
Old insulation that's soaked, matted or full of droppings comes out before anything new goes in, because covering it only hides the problem.
Crawl space insulation
Cold floors over a crawl space usually mean insulation between the joists has thinned or fallen down. We put it back in place and fasten it so it stays put.
Wall insulation
Walls in older houses are often thin or empty. We fill them through small openings where we can, so a drafty room holds its temperature without opening up the whole wall.
Air sealing services
Air sealing means closing the gaps before insulating. We track down leaks around pipes, wires and the hatch, since insulation alone won't stop air from moving.
Basement insulation
For houses with a basement or lower level, we insulate the walls and the rim where the floor framing sits, which is where a lot of cold air gets in.
Closed-cell foam insulation
Closed-cell foam is dense foam that blocks moisture as well as air. We use it where damp is a worry, like a rim joist or a tight roofline.
Open-cell foam insulation
Open-cell foam is softer and lighter, and it fills odd-shaped gaps well. It suits rooflines and walls that stay dry, at a lower cost than closed-cell.
Commercial insulation
We insulate offices, shops and rental units for property managers and small business owners, and we plan the work around your tenants and your hours.
Crawl space vapor barrier
A vapor barrier is a sheet laid over the dirt to keep ground moisture out of the crawl space. We overlap the sheets and seal the seams so damp can't slip through.
Vapor barrier installation
We add vapor barriers in walls, crawl spaces and other spots where damp air would otherwise soak into the insulation and framing over time.
Attic air sealing
Before new insulation goes down, we seal around can lights, pipes, the hatch and wall tops, so the attic stops pulling air from the rooms below.
Retrofit insulation
Retrofit work adds insulation to a finished house without gutting it. We top up attics, fill walls and seal gaps in an order where each step does its job.

Anaheim insulation questions we hear most
These are the questions Anaheim homeowners ask us most about permits, licenses and what happens to the old insulation up there.
Do I need a permit to insulate my attic in Anaheim?
It may need one, since the city says most improvements need a permit before construction starts and only cosmetic work goes without. The Anaheim Building Division handles plan review and inspections, so it can answer for your own job. Before we start, we check what the city asks for at your address, and when a permit is needed we handle the paperwork and line up the inspections.
Does an insulation contractor need a state license in California?
Yes, for most jobs. The Contractors State License Board requires a license when the work needs a building permit, uses any additional workers or comes to $1,000 or more in labor and materials. Anaheim also requires a city business license from anyone doing business there, including businesses based outside the city. We're licensed and fully insured.
Should old attic insulation be removed before adding new insulation?
Only when it's soaked, moldy or full of droppings, because clean, dry insulation can usually stay and get topped up. Laying fresh material over a bad layer keeps the problem in your attic. If the stains come from a roof leak, I'll tell you to get the roof fixed first, since the next winter rain would find the new insulation too.
