Attic acting like a radiator in summer? Proper insulation cuts that heat load and keeps your cooling bills manageable.

Under-insulated attic full of odd angles? Blown-in fills every corner without the gaps batt rolls leave behind.

Rooms too hot in summer and drafty in winter? A full home insulation upgrade fixes both at once.

Old insulation that smells, sags, or harbors pests has to go before new material can do its job.

Wet winters push moisture under your house. Crawl space insulation keeps the cold out and the structure dry.

Walls with no insulation let heat pour in from every direction. We fill existing cavities without tearing out drywall.

Insulation slows heat - air sealing stops it. We close the gaps that let conditioned air escape year-round.

Cold floors and a damp basement cost you money every month. Basement insulation cuts that loss at the source.

Need a moisture barrier and thermal seal in one material? Closed-cell foam handles both in crawl spaces and attics.

Open-cell foam fills interior walls and irregular cavities while adding meaningful soundproofing between rooms.

Commercial buildings lose thousands in energy every year through poor insulation. We fix that for warehouses, offices, and more.

Moisture under your home leads to mold and rot. A vapor barrier stops groundwater from reaching your framing.

Properly installed vapor barriers protect your walls and floors from the moisture that destroys them over time.

Air sealing your attic before adding insulation is the step most contractors skip - and the one that matters most.

Older home that was never properly insulated? Retrofit insulation improves performance without major demolition.
Learn MoreReach out by phone or the contact form. We ask a few quick questions about your home - its age, the area you want insulated, and anything you have noticed, like high bills or uneven temperatures. You do not need all the answers. We come prepared to figure out the rest. Most homeowners hear back from us within 1 business day.
We come to your home and inspect the areas in question - the attic, crawl space, walls, or all three. We measure what is there, check for moisture or damage, and look for air gaps that undermine even good insulation. You get a written estimate before any work is scheduled. Ask as many questions as you want during this visit.
Our crew arrives on the scheduled day, works in the designated areas, and cleans up before leaving. When the job is done, we walk you through the finished work so you can see the coverage yourself. If a rebate or permit applies to your project, we handle the documentation. Your home is ready to use the same day.
Oroville Insulation carries a current contractor license issued by the California Contractors State License Board and maintains full general liability and workers compensation coverage on every project we take on.
We have been serving Oroville and Butte County since 2018. We live and work in the same communities as our customers, which means faster response times and a genuine stake in doing good work.
Every estimate is free, written, and detailed enough that you can compare it line for line with other quotes. We never add surprise charges after the job is underway. What we quote is what you pay.
If the coverage is uneven, a gap was missed, or anything about the finished work is not right, we come back and fix it at no charge. We put that commitment in writing before any job begins.

“They came out the same week I called and the attic job was done in one day. My upstairs bedrooms were noticeably cooler by that weekend, which was a big deal during a July heat wave. Really glad I finally got it done.”
James R., Oroville - Attic insulation
“I had spray foam put in the crawl space after a wet winter left some moisture under the house. The crew explained what they were doing and why, walked me through the finished work, and left the place clean. No surprises on the bill either.”
Maria T., Chico - Spray foam insulation
“We had old blown-in that had settled down to almost nothing and the house was leaking air everywhere. They removed the old stuff, sealed the gaps, and blew in new insulation all in one visit. The difference on our PG&E bill the next month was real.”
David K., Paradise - Blown-in insulation

A poorly insulated attic acts like a solar collector, radiating heat into your living space all afternoon and evening. Adding insulation to the attic floor is the single most effective fix for this problem. The U.S. Department of Energy recommends R-38 to R-60 for attics in California's inland regions - most older homes fall well short of that.
Learn more about insulation R-values at Energy.govInsulation alone does not filter air, but the air-sealing work that accompanies a quality insulation job closes the gaps around pipes, fixtures, and framing where outdoor air enters. Homes with properly sealed building envelopes see meaningfully less smoke infiltration during fire events - a real concern in Butte County.
Yes - and you should check it. Homes built before 1980 were typically insulated to standards far below what is recommended today. Many have just a few inches of compressed material that has lost most of its effectiveness. A quick look at your attic floor tells the story: if you can see the ceiling joists, the insulation is too thin.
Closed-cell foam is the right choice for crawl spaces. It is denser, moisture-resistant, and creates a true vapor barrier. Open-cell foam is softer and absorbs moisture rather than blocking it - the wrong tool for a wet or damp space. Your contractor should recommend based on where the foam is going, not just what costs less.
For most straightforward attic or crawl space jobs, a permit is not required in Oroville. If your project is part of a larger renovation - adding a room, replacing HVAC, or finishing a basement - California's energy code applies and the insulation must meet current standards. Your contractor should know which situations require a permit and handle the paperwork.
Visit the City of Oroville website for permit informationYes. PG&E serves Oroville and offers rebates for qualifying insulation upgrades through its Home Upgrade program. The amount depends on your home's starting point and the scope of work. Some contractors are enrolled in the program and handle the rebate paperwork for you. Ask upfront whether the contractor participates before you sign anything.

Spring and fall are ideal - attic temps are manageable for crews and the work is done before peak summer heat or winter rain arrives. That said, insulation can be installed any time of year. The best time is when your home needs it.
Old, wet, compressed, or pest-damaged insulation needs to be removed before new material goes in. Installing new insulation on top of damaged material traps the problem and undermines the new layer. We inspect first and recommend removal only when it is actually necessary.
A reputable contractor walks you through the finished attic or crawl space before leaving. For blown-in work, they leave depth markers so you can verify coverage yourself with a flashlight. Ask to see photos if direct access is not practical.

Oroville is the county seat of Butte County, sitting along the Feather River at the edge of the northern Sacramento Valley - about 70 miles north of Sacramento. The city is home to around 20,000 residents and is best known for the Oroville Dam, the tallest dam in the United States, which sits just east of town and creates Lake Oroville, a landmark every local knows well.
A large share of Oroville's housing stock was built before 1980 - many in the 1940s through 1960s - in established neighborhoods near downtown and along the Feather River corridor. These older wood-frame homes were built to insulation standards far below what is recommended today. According to Census Reporter, a significant portion of the city's housing units predate 1980. That age gap shows up on energy bills every summer, when temperatures regularly climb past 100 degrees and thin or compressed attic insulation can no longer keep up.
Oroville and the surrounding Butte County area have also lived through serious wildfire seasons. The 2018 Camp Fire devastated nearby Paradise and sent smoke and ash across Oroville for weeks. For families in this area, a well-sealed home is not just about comfort or energy savings - it is a meaningful line of defense during smoky fire seasons. Oroville Insulation knows these conditions because we live and work here too.
