Old fiberglass batts slow heat but leave air leaks wide open. Open-cell foam seals gaps and insulates in one pass, so Merced homes stay cooler with less work from the AC.
Open-cell foam insulation in Merced fills attics, wall cavities, and crawl spaces with a soft, expanding material that handles both insulation and air sealing at once, and most residential attic jobs are finished in a single day.
Most homes in Merced were built before modern energy codes required tight building envelopes. That means gaps around plumbing penetrations, electrical boxes, and framing connections that let your conditioned air escape all day. Traditional fiberglass batts slow heat transfer but do nothing about those gaps. Open-cell foam expands roughly 100 times its original volume, filling every crack it touches, which is why it tends to deliver a more noticeable comfort improvement in older Merced homes than a simple batt replacement would.
Many Merced homeowners combine open-cell foam with attic air sealing to address both the ceiling plane and the attic floor in one project, getting the most out of both services together.
If your electricity bill climbs sharply between June and September and your air conditioner seems to run almost constantly, your attic is likely letting in far more heat than it should. In Merced, where summer temperatures regularly exceed 100 degrees, a poorly insulated attic is one of the most common causes of high cooling costs. Going into your attic on a hot afternoon will confirm the problem: if it feels like an oven, that heat is moving directly into your living space.
If one or two rooms are always hotter in summer or colder in winter than the rest of the house, conditioned air is likely escaping through gaps in the walls or ceiling. The thermostat controls the whole system, but it cannot compensate for air leaking out of a specific room. Open-cell foam seals those leaks and helps the whole house reach a more even temperature.
Stand in your attic on a bright day and look around. If you can see light coming through gaps around pipes, wires, or the eaves, outside air is moving freely in and out of your home. You might also feel a draft near electrical outlets on exterior walls, especially during Merced's winter months. These are direct signs that your home's air barrier has gaps that insulation alone cannot fix.
Merced's agricultural surroundings mean the outdoor air carries fine dust, especially during harvest season in late summer and fall. If dust accumulates quickly near ceiling vents or along ceiling edges, outside air and everything in it is finding its way into your living space. Sealing the attic with foam reduces the pathways that dust uses to enter.
Our most common open-cell foam application is the attic. We spray the material directly onto the attic floor joists or roof deck, where it expands to fill every gap and creates a continuous air and thermal barrier. For homeowners dealing with Merced's summer heat load, this is often the single highest-impact improvement you can make to a house.
For walls that are open during a renovation, open-cell foam can be sprayed into the stud bays before the new drywall goes up, giving you a sealed, insulated wall in one step. We also work with homeowners who want to combine this with attic air sealing to address both the large foam application and the precision gap-sealing work around every penetration.
If you are weighing open-cell against other options, spray foam insulation covers both open- and closed-cell applications, and we will walk you through the trade-offs during the estimate. Open-cell is softer and more budget-friendly; closed-cell provides a higher R-value per inch and adds structural rigidity. The right choice depends on your space, your goals, and your budget.
Best for attics where coverage, air sealing, and budget are all priorities in a single application.
Best for open walls during renovations where a combined air and thermal barrier is needed before drywall goes up.
Best for crawl spaces with moisture-controlled environments where a softer, vapor-permeable material is appropriate.
Merced sits in the San Joaquin Valley, where summer temperatures regularly push past 100 degrees and sometimes past 110 during heat events. An attic that is not sealed and insulated properly can hit 150 degrees or higher on those afternoons, forcing your air conditioner to fight a constant flow of heat through the ceiling into your living space. Open-cell foam addresses that heat load directly, and the payoff in this climate tends to be faster and more noticeable than in milder parts of the state.
A large share of Merced's housing stock was built before the mid-1970s, when energy codes were minimal. Homes near downtown, in the older neighborhoods off G Street and Canal Street, and throughout the pre-1980 subdivisions often have little or no insulation in attic floor areas, and no air sealing at all. Merced County's agricultural activity also means the outdoor air carries more dust and particulates than most regions, and an unsealed attic lets all of that in. Homeowners near Turlock and Modesto face the same conditions, and we work throughout the valley.
California's Title 24 energy code sets minimum standards for insulation work done as part of a permitted project. If your foam application is tied to a re-roof or larger renovation, we handle the compliance documentation. Merced homeowners are also in PG&E territory and can access utility rebates for qualifying upgrades, which we document as part of every job. Details on current programs are available at energystar.gov.
We ask a few basic questions about your home's age, which areas feel uncomfortable, and whether you have noticed specific comfort or energy problems. You do not need to know anything technical before this call.
A contractor visits your home to inspect the attic, check for moisture issues, and measure the area. You receive a written quote breaking down the cost within one business day. No obligation.
The crew masks off surfaces, then sprays foam in even passes across the target area. The foam expands and hardens within seconds. Most attic jobs are complete in a single day, and you can remain home throughout.
After 24 hours of curing, we walk you through the finished work. We provide documentation for any qualifying PG&E rebates and federal energy efficiency tax credits so you can recover a portion of the project cost.

(209) 308-1176Our California C-2 Insulation and Acoustical contractor license is active and verifiable on the CSLB website. Every job is backed by liability insurance and workers' compensation, so you have coverage if anything goes wrong.
We have worked on homes across Merced, Turlock, Modesto, and nine other communities in the valley since 2022. That means we know the housing stock, the climate, and what is typically found in pre-1980 attics throughout this region.
Our installers follow training standards developed by the Spray Polyurethane Foam Alliance, the national trade group for foam contractors. Correct spray technique is what separates a job that delivers on its energy savings promise from one that creates new moisture problems.
PG&E offers rebates for qualifying insulation upgrades, and the federal government currently provides a tax credit of up to 30 percent on eligible work. We provide all the paperwork you need to claim both, so the money does not get left on the table.
A California C-2 license, valley-specific experience, and properly trained installation crews are the combination that makes a foam job perform the way it should. When you hire us, you get a contractor who knows Merced's housing stock, follows California's current standards, and handles the rebate paperwork so you do not have to. Verify our CSLB license online before you call if you like.
