Spray foam insulation
Spray foam seals air and insulates in one pass, and it earns its higher cost when your ductwork runs through the attic. Otherwise I'll usually point you toward sealing and loose fill.
Insulation contractor in Fullerton, CA - upstairs rooms that stay comfortable
South Whittier Insulation and Spray Foam is an insulation contractor working in Fullerton, CA. We seal attic gaps, remove old insulation and add blown-in or spray foam for houses with hot upstairs rooms, drafty floors or a high power bill.
What insulation work looks like in Fullerton
We're an insulation contractor based in South Whittier, and we take jobs in Fullerton the same way we do in Anaheim and East Los Angeles. The calls here usually start with a bedroom upstairs that won't cool off, a room over the garage nobody wants to sit in, or an attic where the old insulation has packed down thin and gone gray with dust. In the older houses we often find just a few inches up there, and in the newer ones the ductwork tends to run through the attic, which changes what I'd put down.
What moves the price is the size of the attic, whether the old insulation has to come out first, how many gaps need sealing, and foam versus loose fill. The schedule turns on the same things, plus a permit if your job needs one, and the estimate I write after seeing your attic gives you your own number. In the older houses, removal is usually the big swing.
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 hides the leak instead of stopping it.
Old material checked first
If what's up there now is soaked or full of droppings, it comes out before anything new goes in. If the roof leaks, I'll tell you to get that fixed first.
Eave vents kept open
We hold insulation back from the vents along the eaves when we add it, because a buried vent stops the attic from breathing and moisture starts showing up in the framing.
Insulation services we offer in Fullerton
Attic insulation
We measure how many inches are up there now, pull out anything wet or dirty, seal the gaps, then bring the whole attic up to an even depth.
Blown-in insulation
Blown-in is loose fill sent through a hose, and we run it full depth out to the edges of the attic, not piled deep in the middle and thin over the walls.
Home insulation
For the whole house, we start in the attic, then look at the walls, the floors and the room over the garage to find where your comfort is actually going.
Insulation removal
When old insulation is matted, soaked or full of droppings, we vacuum it out and bag it before anything new goes in, so the problem doesn't stay hidden under fresh material.
Crawl space insulation
Cold floors over a crawl space usually mean thin or fallen insulation under the floor, and we replace it and hold it tight against the subfloor where it belongs.
Wall insulation
Walls in older houses are often empty, and we fill them through small holes that get patched afterward, so the drywall and stucco stay where they are.
Air sealing services
We find and close the spots where outside air gets in, around pipes, wires, can lights and the hatch, so the insulation you pay for isn't fighting a draft.
Basement insulation
Basements are uncommon around here, but when a house has one, we insulate the walls with material that handles damp concrete so the room stays usable.
Closed-cell foam insulation
Closed-cell foam is dense foam that blocks moisture as well as heat, so we use it where damp air is the bigger problem, like a crawl space or the rim of the floor framing.
Open-cell foam insulation
Open-cell foam is lighter and softer, a good fit for rooflines and walls where you want the air sealed and some noise cut without paying for dense foam.
Commercial insulation
For shops, offices and rental buildings, we work with the owner or property manager on access and timing, so tenants and customers keep going while we're up top.
Crawl space vapor barrier
A plastic liner over the crawl space dirt keeps ground moisture away from the framing, and we lap and tape the seams so it stays put when someone crawls through.
Vapor barrier installation
A vapor barrier only helps on the correct side of a wall or floor, so we check how the space is built before we hang one, since the wrong side traps moisture.
Attic air sealing
Before any insulation goes down, we seal the tops of the walls, the can lights, the plumbing pipes and the hatch from above, because that's usually where attic drafts start.
Retrofit insulation
For a finished house, we add insulation where it's missing without tearing things apart, working from the attic, the crawl space or small holes in the walls.

Questions about insulation work in Fullerton
Here are a few questions Fullerton homeowners ask about permits, picking a contractor and what install day looks like.
Does attic insulation in Fullerton need a permit?
Fullerton's permit list doesn't name insulation by itself, so we check with the city about your address before anything starts. The Building Division says additions, remodels and new or replaced electrical, mechanical and plumbing items generally need a permit, and no construction is allowed until one is issued. If your job needs one, we handle the paperwork and line up the inspections.
Does an insulation contractor working in Fullerton need a city business registration?
Yes. The City of Fullerton requires anyone doing business or a trade in Fullerton to get a business registration certificate before the work begins, and the city may ask for proof of a State contractor license before it issues one. Ask any contractor you're considering, us included, to show you both before work starts.
Do I have to leave my Fullerton house while you insulate the attic?
For blown-in insulation and air sealing, usually not, because the work stays in the attic. Spray foam is different. You, the kids and the pets stay out until the re-entry time passes, which is the wait the foam maker sets, and I'll give you that before we book. Crew time in the attic depends on its size and whether old insulation comes out first.
