About Fullerton, CA

The houses we get called to in Fullerton cover a wide range. Near the older middle of town there are bungalows and Spanish-style homes from before the war, many sitting on raised floors. Around them are blocks of single-story postwar tracts with low roofs, and farther north toward the hills are newer two-story homes. Small offices, shops and apartment buildings are in the mix too, which is where our calls from property managers and business owners come from.

Our crew comes over from Downey, so Fullerton is regular ground for us. Most jobs here come down to what the house sits on and how the roof is framed, because a raised floor means a crawl space to work in and a low roof means a tight attic where the edges are the hardest part to reach.

Services in Fullerton, CA

  • Attic insulation

    In a lot of the single-story tract homes here, the old attic insulation sits deep in the middle and thin out by the eaves, which is backward. We even out the depth edge to edge and keep the eave vents clear so the attic can still breathe.

  • Attic air sealing

    Older Fullerton homes usually have can lights, pipe runs and a loose attic hatch that let hot attic air straight down into the rooms. We do the air sealing, closing those gaps before any insulation goes on, so the new layer isn't fighting a draft.

  • Wall insulation

    Many of the prewar houses here have little or nothing in the walls, so the sunny side of the house heats up and the plaster feels cold in winter. We do wall insulation by filling each cavity through small holes we patch afterward, so you keep the walls you have.

  • Crawl space insulation

    Houses on raised floors often have bare joists underneath, or batts that have sagged and fallen, which is why the floors feel cold on winter mornings. We clear out what's down there, insulate between the joists and hold it in place so it stays up.

  • Spray foam insulation

    In the two-story homes up north, the ductwork often runs through the attic, so cool air warms up before it ever reaches the bedrooms. We spray foam along the underside of the roof, which puts those ducts inside the insulated space instead of out in the heat.

  • Commercial insulation

    Managers of small offices, shops and apartment buildings around Fullerton call us about units that won't hold a temperature. I walk the space with the manager, and we plan the work around tenants and business hours.

Working in Fullerton: permits, paperwork and what sets the price

Building permits here come from the city's Building Division, and the city doesn't allow construction until a permit is issued, so when a job needs one, the start date waits on that review. Before anyone goes up into your attic, you can ask to see their state contractor license and their Fullerton business registration certificate. We're licensed and insured. When your job needs a permit, we take care of it with the city, and if it isn't clear whether yours does, we'll find out with you. The price mostly moves with the size of the attic or crawl space, how tight it is to work in and whether old insulation has to come out first. The schedule turns on the permit and any cleanout. Your written estimate lays out each step, so you can see where your own number comes from.

Fullerton runs right up against Anaheim, and we work on both sides of that line, but each city handles its own permits, so I confirm which office covers your address before anything gets filed. We drive in from Downey, and in summer we start early so the crew is in your attic before the afternoon heat makes it hard to work safely. Near the university plenty of houses are rentals, and when that's the case we set times with the owner and the tenants together.

Fullerton, CA properties and local conditions

On summer afternoons here, heat builds up in the attic and keeps soaking down through the upstairs ceilings well into the evening, which is why the bedrooms are the last rooms to cool off. When I go up, I often find the original insulation, stained from an old roof leak or full of rodent droppings, and laying fresh material on top of that just buries the problem. So we bag and remove what's spoiled, point out any leak a roofer needs to fix first, and only then insulate.

Plenty of houses here have been added onto, with a converted garage or a back bedroom built onto the original. Where the old roof meets the new one, the insulation often just stops, and that seam is where a room runs hot or drafty, so we find it and close it before we cover anything.

What happens when you call us about a Fullerton house

  1. Call or send a message

    Tell us what's going on, whether it's a hot room upstairs, cold floors or old insulation you're unsure about, and we set a time for me to come by. You don't need answers yet, just the address and what you've noticed.

  2. I come out and look

    I go up into the attic or crawl space, show you what I found and what I'd do first, and you get a written estimate before you're asked to decide anything. It helps if you're home, so I can answer your questions on the spot.

  3. Permit, prep and the install

    When the job needs a permit, we handle it, and the city can typically review smaller projects over the counter if the plan review takes no more than 30 minutes, though it may want a closer look depending on the scope or what's already there. Once the permit is issued, our trained crew removes what has to go, seals the gaps and installs the insulation.

  4. Walk the finished work together

    When the crew is done, I check the work with you before we call the job finished, and I'd rather answer one more question than leave you unsure. Satisfaction guaranteed on every job.

Frequently asked questions

Do I need a permit to insulate my attic in Fullerton?

The city's list doesn't settle it by name, because insulation isn't on it. The city's permit list names work that generally needs a permit, like additions, remodels and new, expanded or replaced electrical, mechanical and plumbing items. So we check with the Building Division about your exact job before anything is booked, including whether it touches the ducts or wiring up there.

Which building codes apply to an insulation job in Fullerton?

Projects submitted now are reviewed under the current California building codes, along with changes Fullerton made for its own terrain, weather and ground. An application filed before those codes took effect may stay under the older ones it was filed under, as long as the permit is issued before that application expires. We keep track of which set your job falls under, so the work matches what the city reviews.

Does an insulation contractor need a business registration to work in Fullerton?

Yes. The city requires anyone doing business in Fullerton to get a business registration certificate before any work begins. The city also says construction contractors need a state license, and it may ask for proof of that license before it issues the certificate.

How much does attic insulation cost in Fullerton?

You get your own number in the free written estimate, and the biggest swing is usually between spray foam and sealed loose fill. Foam costs more and seals air while it insulates. Sealing the gaps and topping up with blown-in, which is loose fill blown through a hose, usually does the job for less unless your ductwork runs through the attic. How many inches are already up there matters too, since a good layer only needs topping up.

How long do we have to stay out of the house after spray foam insulation?

You stay out until the foam maker's re-entry time has passed, which is the wait before people and pets can come back inside, and we give you that time for the product we're using before the job is booked. With blown-in, most families stay home, and we only ask you to keep kids and pets away from the hatch and the work area.

What causes the room over my garage to stay so hot in Fullerton?

Usually it's because that room has unheated space on several sides, with the garage below it and attic around it, and often little insulation in the floor or the short walls next to the attic. Topping up the attic alone rarely fixes it, so I look at the floor over the garage and those side walls too, and we seal and insulate wherever the heat is getting in.
