Older Oroville homes have gaps that regular insulation cannot seal. Closed-cell foam insulates and closes those air leaks at the same time - so your home stays cooler in summer, warmer in winter, and better protected during wildfire smoke season.
Closed-cell foam insulation in Oroville is sprayed as a liquid, expands to fill the space it contacts, and hardens into a dense, rigid layer that both insulates and seals air leaks at the same time. Most residential jobs - a crawl space, rim joist, or attic application - are completed in a single day, with homeowners back inside within 24 hours of the crew finishing.
Most insulation materials slow heat from moving through solid surfaces but do nothing about air flowing through gaps. Closed-cell foam does both in one application. In older Oroville homes - many built in the 1950s through 1970s with no thought given to air sealing - that combination can produce a dramatic improvement in comfort and energy costs. The foam is also moisture-resistant and will not be damaged by pests the way fiberglass can, which matters in crawl spaces that see seasonal humidity. Pairing it with broader spray foam insulation work throughout the house gives you a comprehensive solution for all the spaces that need it most.
The Spray Polyurethane Foam Alliance provides industry standards for proper installation and re-entry timing, and reputable contractors follow those guidelines on every job. California homeowners may also qualify for PG&E rebates for qualifying insulation upgrades - ask your contractor about program eligibility before scheduling work.
If your air conditioner runs constantly during Oroville's summer heat but your home still feels stuffy by mid-afternoon, heat is getting in faster than your system can handle. In most cases the culprit is an attic or crawl space with old, compressed insulation that is no longer performing. Closed-cell foam in the attic dramatically reduces how much heat transfers into your living space on a 105-degree day.
If you can smell smoke inside your home during a nearby fire event with windows and doors shut, air is getting in through gaps in your walls, attic, or crawl space. Oroville and Butte County residents know what bad smoke seasons look like, and a home that lets smoke in is also letting conditioned air out year-round. That is a sign your home's envelope has significant leaks that foam could seal permanently.
If floors in your home feel noticeably cold in January or warm in August, the crawl space beneath them is likely uninsulated or poorly sealed. This is especially common in older Oroville homes on raised foundations, where the crawl space is open to outside air. It is one of the most direct signs that heat and cold are moving through your floor rather than being blocked.
If your utility bills have been creeping up year over year with no obvious reason - no new appliances, no change in habits - your home's insulation may be degrading or was never adequate. Older fiberglass insulation compresses and loses effectiveness over time, and homes that were never properly air-sealed lose conditioned air constantly. A noticeable jump in summer cooling costs is one of the clearest signals your home needs attention.
We apply closed-cell foam to the areas of your home where both insulation and air sealing are needed together. Attic rafters, crawl space walls, rim joists, and basement perimeter walls are the most common locations in Oroville homes. The foam expands immediately on contact, fills gaps around pipes and wires, and cures to a hard layer that will not sag, shift, or compress over time. This makes it especially well-suited for tight or hard-to-reach spaces where other materials are difficult to install correctly. We also offer open-cell foam insulation for interior walls and spaces where a softer, vapor-permeable foam is a better fit than the dense closed-cell formulation.
Every job begins with a site walk where we assess the space, check for moisture, and take measurements. We explain what we propose, why we recommend it over alternatives, and what the installation day will look like - including exactly when you can return home. California's building energy standards set minimum performance levels for insulation in permitted renovations, and Oroville falls in a climate zone with specific requirements. We know those requirements and make sure any permitted work meets or exceeds what the city expects.
Best for homes where the attic is used as conditioned space or where unvented attic assemblies are part of the plan.
The most common and cost-effective application in older Oroville raised-foundation homes - seals and insulates in one pass.
For basements where both moisture resistance and air sealing are priorities alongside thermal performance.
For homes that need precision work around pipes, ducts, and structural openings where other materials cannot reach.
Oroville sits in the northern Sacramento Valley where summer temperatures regularly exceed 100 degrees and sometimes push past 110 degrees. That kind of heat puts enormous strain on air conditioners and makes a poorly insulated attic feel like an oven inside the house. Closed-cell foam's ability to block both heat and air movement makes it especially effective here - homeowners often notice the difference in comfort and on their utility bills within the first summer after installation. Wildfire smoke is another real concern in Butte County: foam seals the same gaps that let smoke particles infiltrate during bad fire seasons, giving families with respiratory concerns a meaningfully safer home to shelter in. Homeowners in Paradise and Chico face the same climate conditions and wildfire risk, and we serve both communities regularly.
Older homes in Oroville - particularly those built in the 1950s through 1970s - often have crawl spaces that are completely uninsulated and open to outside air. Cold and heat move freely through the floor in these homes, and there is little homeowners can do to stay comfortable without addressing it at the source. Closed-cell foam applied to crawl space walls and the underside of the floor is one of the most cost-effective upgrades available for this type of home, because it solves the air leak and insulation problem in a single application without requiring major renovation work.
We respond within 1 business day. We will ask what part of the house you want to insulate, whether the home is older or newer, and what comfort or energy problems you have noticed. We do not quote firm prices without seeing the job first.
We look at your attic, crawl space, or walls - wherever the work is planned - take measurements, check for moisture or gaps, and assess accessibility. You receive a written estimate before any work is scheduled. No pressure to sign on the spot.
You and any pets need to be out of the home for at least 24 hours after spraying. Arrange this in advance - book a hotel or stay with family. Your contractor gives you a specific re-entry time in writing before the crew arrives.
The crew arrives with their equipment, protects surfaces that should not get foam on them, and completes the spraying in a single day for most residential jobs. Walk through the work area after re-entry - coverage should be even and complete with no gaps.
Free written estimate with no obligation. We respond within 1 business day and walk you through the full process before any work is scheduled.

We have been installing foam insulation in Oroville and Butte County since 2018. Many of our jobs are in homes built in the 1950s and 1960s - older housing that was constructed before energy sealing was a standard part of the process.
We give you a specific, written re-entry time before any foam work begins - not a vague estimate after the fact. Foam insulation is safe when handled correctly, and clear communication about timing is part of how we do that correctly.
We respond to every inquiry within 1 business day and provide itemized written estimates before scheduling work. Take the time you need to compare options - we do not use high-pressure tactics to get a signature the same day.
Foam insulation requires more preparation and more homeowner communication than most insulation jobs. We take that seriously - written re-entry times, itemized estimates, and honest assessments of whether closed-cell foam is the right choice for your specific home are standard for every project we take on.
A lighter, more flexible foam option suited for interior walls and spaces where vapor permeability is preferred over the density of closed-cell.
