"They came out the same week I called, found that my attic had almost no insulation left, and had the new material installed two days later. My June PG&E bill was noticeably lower than the year before. The crew was clean and professional."
Robert M., Atwater - Attic insulation
"I had that musty winter smell coming up through my floors every tule fog season for years. After they installed the vapor barrier and crawl space insulation, the smell was gone by the next winter. Wish I had done it sooner."
Linda T., Merced - Crawl space vapor barrier
"Our warehouse in Turlock was nearly impossible to cool in summer. They spray foamed the roof deck and the difference was immediate - the building holds temperature now and our tenants stopped complaining. The work was done on time and on budget."

On a 105-degree day, an uninsulated attic can reach 150 degrees or more, radiating heat straight into your living space for hours after the sun goes down. Proper attic insulation acts as a barrier between that heat and your ceiling, which is why it has the biggest impact on cooling costs in this region.
Insulation slows heat movement through solid surfaces, but air sneaks through gaps around pipes, lights, and framing - and air carries heat with it. Air sealing plugs those gaps before insulation goes in. The U.S. Department of Energy recommends combining both for the best results.
The Central Valley tule fog season brings persistent ground-level moisture from November through February. Homes with vented crawl spaces absorb that dampness, which can cause wood rot, mold, and musty odors. A sealed crawl space with a vapor barrier stops that cycle at the source.
Homes built before 1980 were constructed to standards far below what California requires today. Original insulation has also had 40 to 60 years to settle, compress, and degrade. Most older Atwater homes are operating with insulation performing well below its original rating - and well below what current recommendations call for.
Yes. PG&E serves Atwater and has historically offered rebates for qualifying insulation and air sealing upgrades. The federal government also provides a tax credit of up to 30% of the project cost for qualifying improvements. A contractor familiar with these programs can help you apply and ensure the work qualifies.
Open-cell foam is softer and better for interior walls and attics where air sealing is the main goal. Closed-cell foam is denser, delivers a higher R-value per inch, and also acts as a moisture barrier - making it the right choice for crawl spaces and anywhere moisture is a concern. The ENERGY STAR sealing guide explains the distinction in detail.
Atwater Insulation is a licensed and insured insulation contractor based in Atwater, California, serving homeowners and businesses across 12 Central Valley communities since 2016.

California law requires all contractors performing insulation work to maintain a current CSLB license, which you can verify directly on the CSLB website.

Common questions from Atwater and Central Valley homeowners.
In Atwater, the attic is almost always the higher priority. That is where the most heat enters your home during summer. Start there, then address the crawl space if you have comfort or moisture problems in ground-floor rooms.
Your bills will improve, but not as much as they could. Gaps around lights, pipes, and framing let conditioned air escape continuously. The ENERGY STAR program estimates that proper air sealing can cut heating and cooling costs by 15% or more on its own.
Ask the crew to measure the insulation depth at multiple points in your attic before they leave, and ask for photos. Properly installed blown-in insulation should cover the floor joists completely. If you can still see the wood beams, it is not deep enough.

Atwater is a city of about 32,000 people in Merced County, sitting in the heart of California's San Joaquin Valley. Most residents own their homes, and the bulk of the housing stock was built between the 1950s and 1980s - many during and after the years when Castle Air Force Base was active just outside of town. Those homes are now 40 to 70 years old, and most were built to insulation standards that fall far short of what California recommends today.
The climate here is one of the most demanding for home insulation. Summers regularly push past 100 degrees from June through September, with stretches above 105 degrees not unusual. The National Weather Service Hanford/Fresno office tracks conditions across the Central Valley, and the data reflects what Atwater homeowners already know from their energy bills: this is a climate where poor insulation is expensive. Winters bring the Central Valley tule fog - persistent ground-level moisture from December through February that works its way into crawl spaces and under poorly sealed homes. Whether you live near the Castle Air Museum or in one of the newer subdivisions near the edges of town, the insulation challenges are the same.
Atwater Insulation has been working on homes in Atwater and the surrounding area since 2016. We know the older ranch-style homes off Atwater Boulevard, the slab-on-grade construction common across Merced County, and the specific ways that this valley climate punishes homes without proper insulation and air sealing. If you are ready to stop overpaying to heat and cool your home, we are a phone call away.
