Learn MoreReach out by phone or through our contact form. We will ask a few basic questions about your home - its age, which areas you are concerned about, and what is prompting the call. You do not need to know anything about insulation. We will figure out the rest when we visit.
We schedule a free in-home visit, usually within a few days. A crew member walks through your attic, crawl space, or walls, checks current insulation levels, and looks for air leaks. You get a written estimate before we do anything. No obligation, no pressure.
Once you approve the estimate, we schedule the job and handle everything - permits, materials, and installation. We clean up when we are done and walk you through the finished work before we leave. Most homeowners notice a difference in comfort within the first few days.
We carry active California contractor licensing and general liability insurance on every project. You can request proof of insurance before we start - we provide it without hesitation.
Every estimate is free, written, and itemized. You will know exactly what is included before you decide. We never quote over the phone when the job depends on what we actually find in your attic.
We are a locally owned business and have been serving Santa Rosa and Sonoma County since 2016. We know the local housing stock, the climate, and the permitting process at City Hall.
Before our crew packs up, we walk you through the completed job, show you photos, and answer any questions. You should be able to see for yourself that the work was done right.

The crew finished our attic in one day and cleaned up completely before leaving. Our upstairs bedrooms are noticeably cooler this summer and our PG&E bill dropped the very next month. They walked us through everything they did before they left.
Karen M., Santa Rosa - Attic insulation
We had spray foam done in the crawl space and around the rim joists. The musty smell we had every winter is completely gone. The estimator was upfront about what we needed and what we did not - I appreciated not being upsold on things that were not necessary.
David R., Petaluma - Spray foam insulation
Our home is from the 1960s and had almost no wall insulation. They did the retrofit installation without opening up any drywall. The house holds heat so much better now and we finally stopped hearing every car that drives by. Scheduling was easy and they showed up on time.
Michelle T., Rohnert Park - Retrofit insulation
We respond within 1 business day. There is no obligation - the estimate is free and there is no pressure to book. After you submit, someone from our office will call you to schedule a free on-site visit where we assess your home and give you a written price.

If you can see the wooden joists poking above the insulation when you look into your attic, you almost certainly do not have enough. The U.S. Department of Energy recommends R-38 to R-60 for attics in Northern California - most pre-1980 homes fall far short of that.
Yes - significantly. Smoke enters homes through gaps in the attic, around recessed lights, and through unsealed penetrations, not just open windows. Sealing those gaps before adding insulation reduces smoke infiltration. The California Air Resources Board notes that tighter building envelopes improve indoor air quality during smoke events.
Open-cell foam is softer and better for interior walls and attics where you want air sealing and some soundproofing. Closed-cell foam is denser and also resists moisture, making it the right choice for crawl spaces, exterior walls, and anywhere water is a concern. Most contractors will recommend one or both depending on where you need it.
PG&E offers rebates for qualifying insulation improvements in its service territory, which includes Santa Rosa. The federal government also offers a tax credit covering up to 30 percent of the cost of insulation improvements to your primary home. Ask your contractor before signing anything - some rebates require participating contractors or specific materials.
Homes built before 1980 were constructed before modern energy codes required tight air sealing or minimum insulation levels. Many have gaps around pipes, uninsulated rim joists, and attic floors that have never been touched. The result is a home that leaks conditioned air in every season - and pays for it every month on the PG&E bill. The Energy Star program provides guidance on identifying these problem areas.
If you notice a musty smell in your home - especially in the morning or after rain - moisture is likely rising from the crawl space. Santa Rosa's winter rains can drive significant moisture into crawl spaces with no vapor barrier or compromised insulation. Left unaddressed, that moisture encourages mold growth and wood rot, which are far more expensive to fix than the insulation upgrade itself.

If your current insulation has been damaged by rodents, soaked by a roof leak, or contaminated by smoke, adding new material on top of it will not fix the problem. Removal is the right call when the existing material is compromised. A contractor should show you what they found before recommending removal.
In a city like Santa Rosa with PG&E rates among the highest in California, homeowners often see payback in three to seven years through lower heating and cooling costs. Rebates from PG&E and federal tax credits can shorten that timeline. The payback is faster the worse your current insulation is.
Most insulation materials require no ongoing maintenance once installed. The exception is if your attic experiences a new roof leak, pest activity, or other disturbance - in that case, it is worth having the affected area inspected. Beyond that, properly installed insulation should perform for decades without attention.
If you are unsure where your home is losing the most energy, the U.S. Department of Energy insulation guide is a reliable starting point - or call us at (707) 867-4942 and we will take a look for free.
Santa Rosa is the largest city in Sonoma County, with a population of roughly 178,000 people. Nearly half of all housing units are owner-occupied, and a large share of those homes were built between 1950 and 1980 - an era when insulation requirements were minimal or nonexistent. According to U.S. Census data, the median home value in Santa Rosa is around $600,000, which means most homeowners have real equity to protect.
The city has several distinct neighborhoods with very different housing characters. McDonald Avenue is lined with Victorian and Craftsman homes from the late 1800s and early 1900s. The Railroad Square Historic District nearby features stone buildings and older residences. After the 2017 Tubbs Fire destroyed thousands of homes in Coffey Park and Fountaingrove, those neighborhoods were rebuilt from the ground up under current California energy codes - meaning their insulation is already modern. The surrounding older homes that survived the fire are a different story.
Santa Rosa homeowners face a specific combination of challenges: hot, dry summers with temperatures reaching the 90s, wet winters with heavy seasonal rainfall, recurring wildfire smoke events, and expansive clay soils that put stress on foundations and crawl spaces. Santa Rosa Insulation has been working in this environment since 2016, and we understand what the local housing stock actually needs - not just what a national contractor checklist says.
