Spray foam insulation
Foam costs more than loose fill, but it seals air while it insulates. In most attics we see, sealing the gaps and topping up loose fill is the better buy, unless your ductwork lives up there.
Insulation contractor in Fullerton, CA - attics checked and explained first
B&J Pico Rivera Insulation Company is an insulation contractor working in Fullerton, CA. We insulate attics, walls and crawl spaces, seal the air leaks behind drafty rooms and clear out old insulation that's past saving.
How insulation jobs run in Fullerton
We're an insulation contractor in Pico Rivera, CA, and Fullerton is one of the cities we cover from there, along with Anaheim next door and Whittier on the way back home. A lot of the houses we see here are older, with attic insulation that's settled thin over the years, a room over the garage that bakes all summer and ductwork running through a hot attic.
The price comes down to how big the attic is, how many inches are already up there, whether the old material has to come out first and how many gaps need sealing before anything new goes in. The material you pick moves it too. The schedule turns mostly on removal, on whether a permit is needed and on any roof leak or wiring that should be fixed first, and your written estimate shows your own figure and what's behind it.
Leaks and wiring come first
If I find a roof leak or old wiring up there, I'll tell you to fix it first, because new insulation laid over a wet roof deck or a bad splice only hides it.
We check on permits first
Before work starts, we check with Fullerton's Building Division whether your job needs a permit, and if it does we handle the paperwork and inspections, since the city allows no construction before it's issued.
Clean work in a lived-in house
I spent years working in homes where people were living, so our crew covers the floors under the hatch, keeps the dust up in the attic and cleans up before we leave.
Insulation services for Fullerton homes
Attic insulation
Hot upstairs rooms usually trace back to thin attic coverage. We fill it evenly out to the edges over the outside walls, where a lot of attics end up thin while the middle gets piled deep.
Blown-in insulation
Blown-in insulation is loose fill blown through a hose, so it settles around wires and between framing better than rolls do. We set guards at the eaves first so the vents stay open and the attic keeps breathing.
Home insulation
For a whole house, I start by finding where you're losing your cooled air, from the attic hatch to the floor over the garage, and we fix the worst spots first so the power bill money goes where it counts.
Insulation removal
When old insulation got soaked by a roof leak or is full of droppings, we vacuum it out before anything new goes in, because fresh material laid on top keeps the smell and the problem.
Crawl space insulation
Cold floors over a crawl space usually mean the insulation under them has sagged or dropped onto the dirt. We put it back up between the floor framing and hold it so it stays there.
Wall insulation
Plenty of older houses have empty walls. We fill them through small holes drilled from outside or inside, then patch them, so you get insulation without tearing out plaster or drywall.
Air sealing services
Air sealing means closing the gaps before insulating. Around the house, that's the wall between the garage and the room above it, the holes under sinks and the openings around ducts and vents.
Basement insulation
Basements are rare around here, but where a house has one, or a room that sits partly below ground, we insulate the walls in a way that won't trap dampness against them.
Closed-cell foam insulation
Closed-cell foam is dense foam that blocks moisture as well as heat. It earns its higher cost in tight spots, like the framing along the foundation or under a floor that sees damp air.
Open-cell foam insulation
Open-cell foam is lighter and softer, and it fills odd cavities and the underside of a roof well. It fits a house whose ducts run through the attic, because it brings them inside the cooler space.
Commercial insulation
We also insulate small commercial buildings, like offices, shops and rental properties, and we plan the work around your tenants or business hours so the building can keep running.
Crawl space vapor barrier
A crawl space vapor barrier is plastic sheeting laid over the dirt so ground moisture doesn't rise into the floor framing. We overlap and tape the seams, because a loose seam lets the damp right back up.
Vapor barrier installation
Where a wall, floor or ceiling needs a vapor barrier, we put it on the side the job calls for, because a barrier on the wrong side can trap moisture inside the framing.
Attic air sealing
Before new insulation goes in, we seal the attic floor from above, around can lights, plumbing pipes, wires and the hatch, so the insulation isn't fighting a draft coming up from the rooms below.
Retrofit insulation
Retrofit work means adding insulation to a house that's already finished and lived in. We work through the attic, the crawl space and small wall openings, so the mess stays out of your rooms.

Questions about insulation work in Fullerton
These are the questions Fullerton homeowners ask us about permits, codes, the city's review process and what happens on the day of the job.
Does an insulation job in Fullerton need a permit?
It can, depending on what else the job touches, so we ask the Building Division before we start. The city says permits are generally needed for work like additions, kitchen remodels, garage conversions and window and door changeouts, and for new, expanded or replaced electrical, mechanical and plumbing items. Moving ducts or wiring during an insulation job is where that usually comes up.
Which building codes apply to my insulation project in Fullerton?
Projects submitted on or after January 1, 2026 follow the 2025 California codes and Fullerton's own amendments, which the city wrote for local ground and weather conditions. An application filed before that can stay under the 2022 codes, as long as the permit is issued before the application expires, so an older application shouldn't be left sitting.
Can a small insulation job get a quick plan review in Fullerton?
If it needs review at all, a small job may get it over the counter. The city says projects that need no more than 30 minutes of plan review can typically be handled that way, like small kitchen and bathroom remodels and patio covers. Building & Safety can still ask for a more detailed review depending on the scope or what's already in the house.
Does an insulation company working in Fullerton need a city business registration?
Yes, the city requires anyone doing business or a trade in Fullerton to get a business registration certificate before the work begins. The city also says occupations like construction contractor need a state license, and it may ask for proof of that license before it issues the certificate. It's fair to ask about both when you're comparing contractors.
Do I have to leave the house while my attic is insulated?
Usually not for blown-in insulation or air sealing, since the crew works up in the attic and you can stay home with the hatch closed. Spray foam is different. The foam maker sets a re-entry time, how long before people and pets can come back in, and we tell you that time before the job is booked so you can plan for the kids and pets.
