Heat radiates through a bare attic straight into your living space. Proper attic insulation blocks that transfer and keeps rooms livable all summer.

Blown-in loose fill reaches into corners, gaps, and odd angles that rigid batts miss. It is the most common attic upgrade for older Chico homes.

A whole-home insulation assessment finds where your house is losing energy most. One coordinated project addresses the attic, walls, and crawl space together.

Old, damaged, or rodent-contaminated insulation actively harms your air quality. Removal clears the way for a fresh, properly installed layer.

Cold floors in winter trace back to an uninsulated crawl space. Insulating underneath stops the cold from radiating up and helps protect pipes from frost.
Learn More
Walls built before 1980 often have no insulation at all. Blown-in wall insulation goes in through small drilled holes with minimal disruption to your home.

Air leaks are responsible for up to 40% of heating and cooling loss. Sealing gaps around lights, pipes, and framing cuts that waste before new insulation goes in.

An uninsulated basement or lower floor pulls cold up through your foundation. Insulating the rim joist and walls keeps the cold where it belongs.

Closed-cell foam is rigid and moisture-resistant, making it the right call for crawl spaces, exterior walls, and anywhere water exposure is a concern.
Learn More
Open-cell foam is softer and fills interior wall cavities and attic spaces well. It also provides a sound-dampening benefit in addition to thermal performance.
Learn More
Sealing the attic floor before adding insulation is the step most homeowners skip. It plugs the gaps around lights and wiring that let heat and smoke move freely.
Learn More
A damp crawl space breeds mold and rots floor joists over time. A vapor barrier keeps ground moisture out and protects the structure above it.
Learn More
Vapor barriers under the home and in crawl spaces control moisture before it becomes a structural problem. Proper overlap and sealing make the difference.
Learn More
Retrofit insulation upgrades an existing home without full renovation. It is the most cost-effective way to bring older construction up to modern performance levels.
Learn More
Commercial buildings have higher occupant loads and larger HVAC systems. Proper commercial insulation reduces operating costs and keeps conditions consistent throughout.
Learn MoreReach out by phone or online. We ask a few quick questions about your home and what you are noticing — high bills, cold floors, or smoke smell getting in. Most requests get a response within 1 business day, and we schedule a free on-site estimate from there.
A contractor visits your home and inspects the attic, crawl space, or walls. We measure what is already there, look for moisture or air leak issues, and explain what we find in plain language. You receive a written, itemized estimate before we leave — no vague ranges.
On install day, the crew sets up, completes the work, and walks you through the results before leaving. We handle permit coordination when required. If a city inspection is needed, we are present for it. Questions after the job? Call us — we are local.

We are a local company with local knowledge. We know the housing stock in Chico's older neighborhoods, we understand the PG&E rebate programs, and we are here after the job if you have questions.

"The crew showed up on time, finished the attic job in one day, and took photos of the finished depth before they left. My upstairs rooms stopped feeling like a sauna within the first week of hot weather."
"We had spray foam put in the crawl space after a cold winter left us with freezing floors and a burst pipe scare. The difference was immediate. The floors are warm now and the crawl space smells dry and clean."
"After the smoke season two years ago I could smell it inside even with the windows shut. They sealed up the attic floor and gaps around the recessed lights. This past fire season the air inside stayed clean."
We respond to every request within 1 business day. There is no obligation and no pressure - a free estimate is just that. After you submit, someone from our office will call to schedule a free on-site visit so we can see your home and give you an accurate written quote.

An under-insulated attic lets radiant heat pour through the ceiling into your living space. In a climate that regularly hits 105°F, that transfer is relentless. Proper attic insulation - targeting R-38 to R-60 for Northern California - is the most direct fix.
Air sealing plugs the gaps around light fixtures, pipe penetrations, and framing before insulation goes in. The U.S. Department of Energy attributes 25 to 40% of heating and cooling loss to air leaks. Sealing first makes every dollar of insulation work harder.
Blown-in insulation fills irregular attic spaces without demolition, making it ideal for homes built before 1980. Spray foam is better for crawl spaces and rim joists where moisture resistance matters. A contractor should assess your specific home before recommending either.
Yes. Smoke enters through the same gaps that let conditioned air escape. Spray foam and air sealing address those pathways directly. This is a real consideration in Butte County, where fire season smoke events affect indoor air quality. Learn more from the{' '} Butte County Air Quality Management District at bcaqmd.org.
For most straightforward blown-in attic jobs, a permit is not required. If the project is part of a larger renovation or involves HVAC changes, California's energy code may apply. Your contractor should know the answer for your specific scope and pull the permit if one is needed.
PG&E offers rebates for qualifying attic insulation upgrades that meet current efficiency thresholds. Amounts and requirements change periodically. Visit{' '} pge.com for current program details, and ask your contractor if your planned upgrade qualifies before signing anything.

Learn more about Chico InsulationIf your attic insulation is visibly thin, compressed, discolored, or smells musty, it has lost effectiveness. Insulation that has absorbed moisture or smoke damage does not recover. Replacement - not topping off - is the right call in those cases.
Peek into your attic. If you can see the floor joists clearly through the material, you do not have enough. Northern California homes should target R-38 to R-60 in the attic. A contractor can measure your current depth and calculate exactly how much more is needed.
In crawl spaces, rim joists, and areas with active moisture exposure, yes. Spray foam seals and insulates in one step, and it lasts as long as the structure. For open attic floors, blown-in is usually the better value. The right product depends on the space.

Chico is a city of about 103,000 residents in Butte County, situated in the northern Sacramento Valley. The city is home to California State University, Chico, and is bordered to the north and east by foothills leading to the Sierra Nevada. Summers here are long, dry, and intensely hot, with temperatures regularly climbing past 100°F from June through September.
A significant share of Chico's residential neighborhoods - including areas near Bidwell Park, the Avenues, and older streets near Downtown Chico — were built in the 1950s through 1970s, well before modern insulation standards. Many of these homes have original insulation that has compressed or degraded over decades, or no wall insulation at all. The combination of extreme summer heat and older housing stock makes this one of the highest-value markets in California for insulation upgrades.
The Chico area has also experienced serious wildfire smoke events in recent years, most notably following the 2018 Camp Fire that destroyed nearby Paradise and displaced tens of thousands of residents across Butte County. Homeowners who lived through those smoke events understand firsthand that a leaky home is not just uncomfortable — it is a health concern. Insulation and air sealing work together to reduce outdoor air infiltration, including smoke particles that enter through the attic, crawl space, and gaps around penetrations.
Chico Insulation serves homeowners throughout the city — from neighborhoods along Bidwell Park to ranch-style homes on the east side and properties close to the university. We know the housing stock here, we understand local permit requirements, and we are familiar with the PG&E rebate programs that can offset a portion of your project cost. If your home is in Chico and you have questions about insulation, call us for a free assessment.
