Your home loses cooled air through dozens of hidden gaps every day. Open-cell foam seals those gaps and insulates at the same time, so your AC stops running overtime and your rooms actually reach the temperature you set.

Open-cell foam insulation in Hemet expands to fill every gap and crack, sealing air leaks and insulating at the same time — most attic jobs are completed in a single day.
Unlike the pink fiberglass batts most older homes were built with, open-cell foam is sprayed in as a liquid and expands to cover every edge, outlet penetration, and pipe gap that batts leave exposed. That matters in a climate where summer temperatures regularly top 105°F and your air conditioner is fighting to keep up.
Many Hemet homeowners who have had open-cell foam installed say they notice the difference in their first SCE billing cycle. If your home was built before 1990 and has never had an insulation upgrade, the improvement is often dramatic. Pairing this service with attic air sealing gives you the most complete thermal barrier for Hemet's desert climate.
The California Energy Commission maintains detailed insulation standards for the inland climate zones that include Hemet. You can review the state's guidance at energy.ca.gov. Our installs meet those requirements, and we document everything through the City of Hemet permit process.
If your cooling system runs almost continuously from June through September but certain rooms never reach the temperature you set, air is leaking in from outside. In Hemet's extreme heat, small gaps around recessed lights or attic hatches can let in enough hot air to overwhelm your unit.
Hold your hand near an outlet on an exterior wall on a hot afternoon. If you feel warmth, outside air is moving through the wall cavity. This is a common finding in Hemet homes built before 1990, where wall insulation was minimal and no air barrier was installed behind the drywall.
If your SCE bills have been climbing year over year without a clear reason — no new appliances, no change in household size — degraded or insufficient insulation is one of the most common causes. Fiberglass batts from the 1970s and 1980s are well below California's current energy standards.
Rodents and insects that nest in attic insulation compress and contaminate the material, leaving gaps that allow heat transfer and air infiltration. If you have had pest control treatment in recent years, your existing insulation was likely disturbed. Open-cell foam fills those cavities and is not a food source for pests.
Most of our open-cell foam work in Hemet falls into two categories: attic applications for homes where heat gain through the roof is the primary problem, and wall cavity work for homeowners who are renovating and want to replace original batts with a continuous air-sealed layer. Both approaches use the same material, but the installation details and the benefit you feel first will differ depending on your home.
For homeowners who want to address the whole house at once, we also offer combined packages that cover the attic, walls, and crawl space in a single project. This approach makes the most sense if you are planning to claim Southern California Edison rebates, since qualifying for those programs often requires meeting minimum performance thresholds across the entire home envelope. Pairing open-cell foam with spray foam insulation in specific zones and adding attic air sealing as a first step gives you the most complete result.
If your home has contaminated or water-damaged insulation that needs to come out first, we handle that as part of the same project. See our insulation removal service for details on what that process involves and how it connects to a foam installation.
Best for homes where heat gain through the roof deck is the primary energy problem and where a single-day installation is important.
Well suited to older Hemet homes during a renovation when walls are open and original batt insulation can be replaced with a continuous air-sealing layer.
Recommended for homes where floor cold spots and moisture-driven comfort issues point to an uninsulated or poorly insulated crawl space.
Ideal for homeowners who want to address attic, walls, and crawl space in a single project to maximize energy savings and qualify for SCE rebates.
Hemet sits in the San Jacinto Valley at about 1,600 feet elevation. Summer temperatures regularly exceed 105°F, and the gap between inside and outside temperatures during peak cooling season is extreme. Open-cell foam's dual role as insulator and air sealer makes it especially well suited to this climate. Every small gap that batt insulation leaves exposed becomes a pathway for that hot air to push into your living space, and the AC runs harder trying to compensate.
A significant share of Hemet's housing stock was built in the 1970s and 1980s — decades before California's current energy code took effect. Original fiberglass batts have had time to settle, compress, and be disturbed by pest activity. Homes in older neighborhoods near Florida Avenue and Seven Hills are particularly likely candidates for a full upgrade. Beyond comfort and energy bills, there is also a wildfire smoke benefit: a well-sealed home keeps far more smoke particulates outside during the fire seasons that affect the San Jacinto Valley each year.
We serve the full area surrounding Hemet, including homeowners in San Jacinto, Beaumont, and Perris. The housing stock, the climate, and the energy code requirements are similar across the region, and our crews know the area well.
We reply within one business day. We will ask the age of your home, which areas you want insulated, and whether you have had recent pest or moisture issues — so we arrive prepared.
We measure your attic, crawl space, or wall areas, explain what we find in plain terms, and give you a written estimate before you agree to anything. If a permit is required, we flag it here and include the fee.
We pull the City of Hemet permit before work begins. This typically adds a few days but means the installation gets independently inspected and goes on record — which protects you at resale.
The crew completes most residential attic or wall projects in four to eight hours. Before leaving, we walk you through every treated area so you can see exactly what was done.
We reply within one business day. No pressure, no obligation — just a clear explanation of what your home needs and what it will cost.
(951) 430-8634Every open-cell foam job we do in Hemet is performed by a contractor holding a current California Contractors State License Board license. We pull permits when required and close them properly — your project goes on record and passes inspection.
We are enrolled in Southern California Edison's rebate programs for qualifying insulation upgrades. That means we handle the paperwork, and eligible Hemet homeowners get money back on a project that was already going to pay for itself in lower monthly bills.
We have installed open-cell foam in hundreds of Hemet-area homes, including 1970s ranch homes near Florida Avenue and newer tracts on the east side of town. We know the housing stock and what it typically needs.
We never start a job without a signed written estimate that itemizes materials, labor, thickness targets, and any permit fees. There are no line items added after the fact. What you approved is what you pay.
Every one of those points connects to a single goal: you should know exactly what was done, why it was done, and what it cost before you write a check. The Spray Polyurethane Foam Alliance sets the training and quality benchmarks our crews follow, and the City of Hemet permit process provides the independent verification. Together, those two layers of accountability mean you are not taking anyone's word for it.
Seal every gap in your attic floor before adding insulation for maximum cooling performance.
