A hot attic bakes through your ceiling in summer. Proper attic insulation blocks that heat and cuts your cooling costs.

Old insulation settled or thinned out? Blown-in loose-fill tops it up fast and fills corners that batts miss.

Cold floors, drafty rooms, high energy bills - a whole-home insulation assessment finds the source and fixes it.

Rodent damage or mold in your attic? Old contaminated insulation has to come out before new material goes in.

Cold, damp air pools under your floors. Crawl space insulation cuts that chill and protects the wood above it.

Learn MoreCall us or fill out our online form. We will ask a few quick questions about your home and what you are experiencing - drafts, high bills, a problem area. We respond within 1 business day. You do not need to know exactly what you need; just describe what you have noticed.
We come to your home at a time that works for you. We inspect the attic, crawl space, or walls, measure what is there, check for moisture or pest issues, and identify every gap worth sealing. You get a written quote that explains what we found and exactly what we will do.
Our crew arrives on the scheduled day, seals air leaks first, then installs the insulation. Most jobs are done in a single day. Before we leave, we walk you through the finished work, provide documentation of what was installed, and answer any questions you have.
We carry a valid California contractor license and full liability insurance on every project. You can ask for our license number before we start. Permitted work gets inspected, which protects your home value and keeps you covered.
Every quote starts with a real visit to your home, not a guess over the phone. We measure, inspect, and give you a written breakdown of what we found and what it will cost. No pressure, no follow-up sales calls if you decide not to move forward.
We are a locally owned business based right here in Petaluma. We know the housing stock, the climate, and the neighborhoods. When you call, you are talking to someone who lives and works in the same community.
Every completed project gets a written record of what was installed, the R-value achieved, and the square footage covered. You will need this for PG&E rebates, permit sign-offs, and home sale disclosures - and we provide it without being asked.
Questions before you commit? Call us at (707) 778-6192 or send us a message.
The crew finished our attic in one day, and the difference in how the upstairs felt that same night was immediate. Our PG&E bill has been noticeably lower every month since.
We had a rodent problem in our crawl space and the old insulation had to go. They removed everything, sealed it up, and installed new material in two days. They found a spot we had not even noticed and fixed it.
Got spray foam done in the crawl space and under the floor. The cold floors we had lived with for years are gone. They showed up when they said they would and cleaned up completely when they left.
We respond within 1 business day - usually the same afternoon. There is no obligation to move forward after we talk. Once you submit, someone from our office will call to schedule your free on-site assessment.

If your insulation is more than 20 years old, has been disturbed by rodents, or shows signs of moisture damage, it likely needs to come out before new material goes in. Installing over compromised insulation traps the problem underneath.
Insulation slows heat movement, but gaps let air pass through regardless of how much insulation is on top. Air sealing closes those gaps first. Skipping it is the single most common shortcut that leaves energy bills unchanged after a job.
Yes. Spray foam seals the same gaps that let smoke in during poor air quality days. After the fire events Sonoma County has seen, this is a meaningful benefit beyond energy savings for Petaluma homeowners.
Homes built before 1980 often have irregular cavities and gaps around old plumbing that batts cannot seal. Blown-in and spray foam both work well in these situations, though the right choice depends on the location and access. A contractor visit is the only way to know for sure.
The U.S. Department of Energy recommends R-38 to R-60 for attics in Northern California's climate zone - which typically means 10 to 16 inches of blown-in material. Most older Petaluma homes fall short of this, especially if the insulation has settled over the years.
In most cases, yes - if the existing insulation is dry, pest-free, and in decent shape, new material can go on top. But if it has been damaged or contaminated, removal is necessary first. The only way to know is to have someone physically inspect it.
For more detail on insulation types and R-values, see the U.S. Department of Energy insulation guide.

Raised-foundation homes in Petaluma lose a lot of heat through an uninsulated crawl space. Insulating beneath the floor stops cold air from pooling underneath and working its way up.
Always before - once drywall goes up, adding insulation to walls becomes a retrofit job that costs more. Any time walls or ceilings are open is the right time to upgrade insulation.
Both work. Cellulose is made from recycled material and performs well in Petaluma's occasionally damp conditions. Fiberglass does not settle as much over time. A contractor visit is the best way to decide.

Petaluma is a city of about 62,000 people in Sonoma County, shaped by the Petaluma River that runs through its center and a housing stock that spans more than 150 years of construction. The west side carries the city's oldest homes - Victorian and Craftsman-era houses along B Street and Liberty Street built between the 1880s and 1930s. The east side holds the newer subdivisions from the 1980s and 1990s. Whatever side of the river you are on, the buildings here have specific needs that come with age, climate, and local conditions.
Petaluma sits in the Petaluma Gap, and the cool marine air that funnels through from the Pacific most afternoons means homes here cycle between needing to block heat and hold warmth - sometimes in the same day. Homes near Lucchesi Park and the Petaluma River waterfront tend to be older and sit on raised foundations, which makes crawl space insulation and vapor barriers a common call. According to Census data, a large share of Petaluma homes were built before 1980 - and homes from that era were constructed before modern insulation standards existed.
Petaluma also has a strong owner-occupied base, with roughly half of all housing units owner-occupied. Homeowners here invest in their properties because they plan to stay - and because home values in the $600,000 to $700,000 range make it worth protecting what you own. From the Historic Downtown to the newer streets near East Washington, Petaluma Insulation has worked on Petaluma homes of every age and style. If your home is losing heat or comfort, we know where to look.
