Older Rohnert Park homes lose conditioned air through gaps batts can not touch. Open-cell foam fills every crack and seals air leaks so your home holds its temperature all year.
Open-cell foam insulation in Rohnert Park is a soft, spray-applied material that expands to fill walls, attics, and crawl spaces - sealing air leaks and insulating at the same time, and most residential jobs are completed in one to two days.
Rohnert Park homes built in the 1960s and 1970s were rarely insulated well to begin with, and decades of settling have made things worse. If your home feels drafty in January or stuffy in July, open-cell foam applied to the attic or wall cavities is often the most direct fix. Unlike fiberglass batts, foam gets into the irregular gaps and corners that batts simply leave open.
Many homeowners pair this work with spray foam insulation when they want the broadest coverage across their home, or start with the attic and add walls in a later phase.
If the second floor or rooms directly under the roof feel significantly warmer on a hot Rohnert Park afternoon, heat is moving through your attic ceiling faster than it should. This is one of the most common complaints in the older ranch-style and two-story homes built here in the 1960s and 1970s, where attic insulation has often settled or degraded over decades.
If your energy bill keeps rising but your habits have not changed, your home is losing conditioned air through gaps and under-insulated areas. Rohnert Park's warm summers and cool winters mean your HVAC system runs hard in both seasons, and every gap in your insulation makes it work harder and longer. A noticeable jump in summer cooling costs is often the first sign homeowners notice.
If you notice a smoky smell inside your home when air quality alerts are active in Sonoma County, outside air is finding its way in through gaps in your attic, walls, or around fixtures. This is both an air quality concern and a clear sign your home's envelope has meaningful leaks. Open-cell foam applied to the attic and around penetrations can dramatically reduce how much outside air gets in.
Hold your hand near an electrical outlet or light switch on an exterior wall on a cold winter morning. If you feel cool air, outside air is moving through the wall cavity into your living space. This is common in Rohnert Park homes built before modern air-sealing practices became standard, and it is a clear sign that the wall insulation - if any exists - is not doing the full job.
We apply open-cell foam to attics, wall cavities, and crawl spaces across Rohnert Park. The foam sprays in as a liquid and expands to fill every corner, gap, and penetration that batts and blown-in materials leave behind. If your project is focused on the attic, we can often complete the work in a single day. If walls or crawl spaces are involved, we scope the full job during your free estimate visit and give you a clear timeline before any work begins. For buildings where you also need to address moisture at the foundation level, we frequently pair this work with our commercial insulation services for larger scopes.
Open-cell foam is also one of the most effective ways to improve indoor air quality during Sonoma County fire season - it closes the same pathways that wildfire smoke uses to infiltrate a home. If air sealing is your primary goal, ask us about combining foam work with our spray foam insulation service, which covers both open- and closed-cell applications depending on what each area of your home needs.

Best for homeowners ready to address every area at once and maximize comfort and energy savings in a single project.
Rohnert Park sits in Sonoma County's inland corridor, where summers can push into the 90s and winter nights drop into the 30s. That swing creates year-round pressure on your home's insulation - it is working in both directions, and any gap shows up as a hot room in July or a drafty hallway in January. Most of the city's housing stock dates from the 1960s through the 1980s, when insulation standards were far lower than they are today. A large share of those homes have attic insulation that has settled, compressed, or simply was not adequate when new. Open-cell foam is particularly well-suited here because it seals air leaks and insulates at the same time - two problems these older homes typically have together.
We serve homeowners across the city, including those near Cotati and south toward Petaluma. California's energy efficiency rules mean that any permitted renovation touching your walls or attic must meet current insulation minimums - and PG&E offers rebates for qualifying upgrades that can meaningfully reduce your upfront cost. A contractor who knows these programs and requirements will make the process straightforward.
We will ask a few basic questions - the space you want insulated, your home's age, and any comfort problems you have noticed. Expect a reply within one business day to confirm your estimate appointment.
We walk the attic, walls, or crawl space, take measurements, and check what is already there. You receive a written estimate before any work is scheduled - no obligation, no pressure.
You will need to clear access to the work areas and plan to be out of the home for about 24 hours after spraying. We tell you exactly what to do before the crew arrives so there are no surprises.
The crew arrives, protects surrounding surfaces, and sprays the foam in sections. Most residential jobs are done in one day. We walk through the completed work with you before leaving and answer any questions.

(707) 210-9475The bulk of our work is in homes built between the 1960s and the 1980s - the same era as most of this city's housing stock. We know what these homes typically have and what they typically need, so there are no surprises during the assessment.
We follow installation practices aligned with the Spray Polyurethane Foam Alliance, the national trade organization for spray foam contractors. That means even, consistent coverage with no thin spots or voids - and we walk you through the work before we leave.
We check rebate eligibility as part of every estimate and flag any programs that apply to your project. PG&E's Home Upgrade program has historically offered meaningful savings for qualifying Rohnert Park insulation upgrades - we help you access that money.
California requires insulation contractors to hold a valid C-2 license from the Contractors State License Board. You can verify any contractor's license before you hire. We carry full liability and workers' compensation insurance on every job.
