Heat pouring through your attic? Spray foam seals air leaks completely, not just slows them down, so your AC runs less on triple-digit summer days.

Can you see the ceiling joists in your attic? If so, you need more insulation, and the right upgrade can measurably cut your summer cooling bills.

Older insulation settled and thin? Blown-in material fills every corner evenly, including irregular spaces batts can't reach, in a single day.

High energy bills with no obvious cause? Upgrading your home's insulation is one of the most direct ways to reduce what you pay to heat and cool every month.

Damaged, moldy, or pest-infested insulation makes your home less healthy. We remove it safely and leave the space ready for a clean, effective new installation.

Your crawl space pulls hot, dusty outside air right under your floors. Insulating that space stops the heat transfer and eliminates a major source of energy loss.

Exterior walls with no insulation let heat and cold press straight through into your rooms. We add coverage to existing walls without major disruption to your home.

Insulation without air sealing is like a blanket full of holes. We seal gaps around pipes, wires, and fixtures so conditioned air stops escaping.
Learn MoreReach out by phone or through the contact form. We ask a few basic questions about your home, the areas you want addressed, and whether you have noticed specific problems like high bills or uneven temperatures. We respond within 1 business day and schedule a free on-site visit at a time that works for you.
We come to your home and inspect the attic, crawl space, walls, or wherever the concern is. We measure what is already there, check for moisture, air leaks, or ventilation issues, and note anything that needs to be addressed before new insulation goes in. You get a written quote within one business day of the visit, with no obligation to proceed.
On the day of the job, the crew seals air gaps before any insulation goes in, then completes the installation. Most attic jobs finish in a single day. Before we leave, we walk you through the completed work, answer any questions, and provide documentation of what was installed, so you have a clear record for rebate applications or future home sales.
We hold a current contractor's license issued by the California Contractors State License Board. Every job is covered by general liability insurance and workers' compensation, so you are protected if anything unexpected happens on your property.
We have been serving Merced and the surrounding San Joaquin Valley since 2022. When you call, you reach someone local, not a call center. We know the housing stock, the climate, and the PG&E rebate programs that can reduce your cost.
Every estimate starts with a real visit to your home. We inspect the actual space, not just square footage you give us over the phone, before writing a number. You get a written quote you can take your time reviewing, with no pressure to sign on the spot.
We respond to every inquiry within 1 business day. Before any work starts, we give you a realistic schedule and stick to it. If something comes up during the job that changes the scope, we tell you immediately, before doing any additional work.

"They came out on a Tuesday, gave me a written quote the same day, and had the attic done by Thursday. My upstairs bedroom actually cooled down for the first time in three summers."
Maria T., Turlock, CA — Attic Insulation
"The crawl space under my house was open to outside air and it showed on my PG&E bill every summer. After the spray foam and vapor barrier work, the floors feel completely different and the musty smell is gone."
James R., Modesto, CA — Spray Foam Insulation
"I had three other companies quote the blown-in job. Merced Insulation was the only one who went up into the attic first and found air gaps around the recessed lights that needed sealing. The others just asked for square footage over the phone."
Linda S., Fresno, CA — Blown-In Insulation
We respond within 1 business day. There is no obligation to proceed after the estimate visit. After you submit, someone from our office will call you to schedule a free on-site assessment at a time that works for your schedule.

A poorly insulated attic acts like an oven above your living space. When outside temperatures exceed 100 degrees Fahrenheit, heat radiates through the ceiling faster than most AC systems can offset it. The fix is almost always more insulation combined with air sealing, not a bigger unit.
Open-cell foam is softer and better for attics and interior walls where sound reduction and air sealing are the main goals. Closed-cell foam is denser, provides a higher R-value per inch, and acts as a moisture barrier, making it the right choice for crawl spaces and exterior applications.
In most Merced homes, the attic is where the most heat enters, so it typically delivers the fastest return. However, if your crawl space is open to outside air and you have cold floors or moisture problems, addressing it first may make more sense. The right order depends on your specific home.
Air sealing closes gaps around pipes, wires, and light fixtures in your attic floor before insulation goes in. Skipping it is the most common shortcut in the industry. Without it, conditioned air escapes through gaps the insulation sits on top of, and a significant share of the potential savings disappears.
Pacific Gas and Electric offers rebates for qualifying insulation upgrades. The amounts change periodically, but they can meaningfully offset your project cost. To qualify, the work typically needs to meet California's energy efficiency standards. PG&E rebate portal has current program details.
Insulation damaged by moisture, rodents, or mold does more than waste energy. It can introduce particulates and allergens into your home's air. If your attic has signs of pest activity, visible mold, or a persistent musty smell, removal and replacement is a health priority, not just an efficiency upgrade.
Merced Insulation is a licensed and insured insulation contractor based in Merced, California, serving 12 cities across the San Joaquin Valley since 2022. We hold a current California contractor's license issued by the Contractors State License Board, and every project we take on is covered by general liability insurance and workers' compensation.
We offer 16 insulation services for residential and commercial properties, from spray foam and attic blown-in to crawl space vapor barriers and whole-home retrofit work. Every job starts with a free on-site assessment and a written quote.
Check your attic on a hot afternoon. If it feels like an oven and the ceiling joists are visible through the insulation, your coverage is too thin. A simple depth check reveals most problems before they show up on your energy bill.
Schedule an assessment before the next summer arrives. An inspector can measure current R-values and identify the highest-priority areas, so you are not guessing where your money will do the most good.
Properly installed spray foam lasts decades without degrading. Unlike blown-in material, it does not settle over time. Closed-cell foam also acts as a vapor retarder, which protects the surrounding structure from moisture damage.
Spring, from March through May, is ideal. Contractors have more availability before the summer rush, the weather is mild for working in attics, and you have the upgrade in place before the hottest months hit. That said, insulation can be installed year-round.
For technical guidance on insulation R-values recommended for California's climate zones, the U.S. Department of Energy's insulation guide is the most authoritative public reference available.

Merced is the county seat of Merced County, situated in the heart of the San Joaquin Valley at about 167 feet above sea level. The city has roughly 90,000 residents and serves as a regional hub for the surrounding agricultural communities. Most of the housing stock was built between the 1940s and the 1980s, with single-story stucco homes on slab foundations making up the majority of the older neighborhoods closer to downtown.
The northeast side of the city looks considerably different. Since UC Merced opened in 2005, newer subdivisions have spread toward Lake Yosemite Regional Park, bringing newer homes with different insulation needs than the older downtown stock. Merced is also known as the Gateway to Yosemite, with Highway 140 running directly from the city to the national park roughly 80 miles away, but the climate here is San Joaquin Valley, not mountain, with summers that regularly push past 100 degrees Fahrenheit.
The weather is what drives most of our work in this city. Summers are long and brutal, winters bring dense tule fog from December through February, and the clay soils under most homes swell and contract with the seasons. Homes near Lake Yosemite and in the older neighborhoods near the historic downtown see very different insulation challenges. Older homes lose conditioned air through thin or absent wall insulation and crawl spaces that pull in outside air. We work on both, across every neighborhood in the city.
