Hemet summers push past 105°F. If your home takes hours to cool down or your energy bills keep climbing, your insulation is not doing its job. We assess, recommend, and install, with no-obligation estimates and same-week scheduling across the San Jacinto Valley.
Hemet Insulation is a full-service insulation contractor based in Hemet, CA, serving homeowners and commercial property owners across the Inland Empire. We offer 16 insulation and air-sealing services, from basic attic upgrades to whole-home retrofits, in 12 cities throughout Riverside County. Many Hemet homes were built before today's energy standards existed. We help homeowners close that gap, room by room or all at once, with a free on-site estimate and a written quote before any work begins.
Air leaks driving up your cooling bills? Spray foam insulates and seals gaps in one pass, making it one of the most effective upgrades for Hemet's triple-digit summers.

Is your upstairs still hot at 9 PM? Proper attic insulation stops heat from radiating through your ceiling all evening, and most jobs are done in a single day.

Older home with irregular framing? Blown-in insulation fills every gap without tearing out drywall, and it's the fastest way to add R-value to an existing attic.

Your whole home, properly wrapped. We assess every area, from attic to walls to crawl space, and recommend only what will actually make a difference for your comfort and bills.

Old insulation that's been disturbed by pests or decades of heat can do more harm than good. We remove it cleanly before any new material goes in.

A cold or damp crawl space pulls heat out of your floors and can raise humidity throughout the house. Insulating it is one of the most overlooked upgrades in this area.

Exterior walls without insulation let heat pour in from every direction. We add insulation to existing walls using low-impact methods that don't require a full renovation.

Gaps around outlets, pipes, and attic hatches are often bigger energy drains than the insulation itself. Air sealing closes those leaks before new material goes in.

A technician visits your home, inspects the attic, walls, or crawl space, and measures what is there. They explain what they find in plain language, identify any air-leak problems worth addressing alongside the insulation, and hand you a written quote before leaving. No obligation to move forward.
Most jobs are completed in one day. The crew works in the attic or targeted areas, cleans up on the way out, and walks you through the finished work before leaving. You see what was done and can ask questions on the spot. If you are applying for a Southern California Edison rebate, we provide the documentation you need.
Our California Contractors State License Board (CSLB) license is current and verifiable online. We carry general liability insurance on every job, and we will show proof before work begins.
Every estimate starts with a technician in your attic or crawl space, not a price over the phone. You receive a written quote that breaks down cost by area before we schedule anything.
We are a local business, not a national chain dispatching crews from three counties away. Our team works in Hemet, Riverside, and the surrounding valley every week and knows these homes.
We install depth markers before every blown-in job, document coverage with before-and-after notes, and walk you through the finished work. You never have to take our word for it.

"Our upstairs used to be ten degrees hotter than the rest of the house all summer. After the attic insulation job, it actually cools down at night now. The crew finished in one day and left the place clean."
David R., Hemet — Attic Insulation
"I got three quotes and Hemet Insulation was the only one who actually went into the crawl space before giving me a number. They found a vapor barrier issue I did not know about. The price was fair and the work was done on the day they promised."
Maria T., San Jacinto — Crawl Space Insulation
"I had spray foam done on the garage wall that backs up to the living room. That room used to be unusable in summer. It made a noticeable difference within the first week, and they explained exactly what they were doing before they started."

Attic temperatures in the San Jacinto Valley can exceed 150°F on a summer afternoon. That heat radiates through your ceiling continuously, and no air conditioner can overcome it without help from adequate insulation.
The U.S. Department of Energy recommends R-38 to R-60 for attics in Hemet's climate zone. Most pre-2000 homes fall well short of that range. If your ceiling joists are visible from the attic, your insulation is too thin.
Spray foam and air sealing close the gaps that let outdoor air, including smoke, enter your home. A properly sealed home is significantly more resistant to smoke infiltration than one with gaps around pipes and outlets.
Closed-cell foam has a higher R-value per inch and resists moisture, making it ideal for high-heat and any area near the ground. Open-cell is softer and less expensive, suited to interior walls and upper attic spaces where moisture is not a concern.
Southern California Edison, which serves Hemet, has offered rebates for qualifying attic insulation upgrades. Ask your contractor before scheduling so the job is documented correctly. Rebate rules change, so check current availability at the SCE website.
Look into your attic with a flashlight. If you can see the ceiling joists clearly, the insulation is too thin. Compressed, gray, or pest-disturbed material is also a sign it needs attention. A free inspection confirms what you have and what you need.
For in-depth guidance on insulation types and R-values, see the U.S. Department of Energy insulation guide.
Hemet Insulation is a licensed and insured insulation contractor based in Hemet, CA, serving homeowners and commercial property owners across 12 cities in Riverside County since 2022. We hold an active contractor's license issued by the California Contractors State License Board (CSLB), which can be verified at any time on the CSLB website.
Since 2022, our crew has completed hundreds of insulation and air-sealing projects across the San Jacinto Valley, including attic retrofits, spray foam applications, crawl space moisture barriers, and commercial building envelope work. Every project includes a written scope of work and a final walkthrough before we close out the job.
If existing material has been disturbed by pests, contaminated, or compressed to less than a few inches, adding new insulation on top often wastes money. Removal and a clean start produce better results.
Spray foam seals air leaks at the same time it insulates. In a climate like Hemet's, where air conditioning runs for months, that combined effect reduces cooling costs more than insulation alone.
Most homeowners notice a change within the first few days, especially if the work was done before or during the hot season. Energy bill changes typically show up on the first or second billing cycle after the job.
The material type, the target R-value or thickness, the total square footage covered, whether air sealing is included, and the total installed cost. If a quote does not include these details, ask for them in writing.

Hemet is a city of roughly 90,000 residents in the San Jacinto Valley in Riverside County, situated at about 1,600 feet elevation inland from the coast. The city has long been a destination for retirees and first-time buyers looking for affordability in Southern California, and a large share of its housing stock dates from the 1970s and 1980s, when insulation standards were far lower than they are today.
The valley sits between the San Jacinto Mountains to the east and the Santa Ana Mountains to the west. Residents near Diamond Valley Lake to the south and those in the older neighborhoods around Hemet Valley Mall and Florida Avenue face the same challenge: summers that regularly push past 105°F, and homes that were not built to handle that kind of heat efficiently.
Hemet is also home to the Ramona Pageant, one of the longest-running outdoor plays in the United States, held each spring in a natural amphitheater in the hills above the city. Whether you live near the pageant grounds or in one of the valley-floor neighborhoods, the climate conditions are the same, and proper insulation is one of the most practical investments a Hemet homeowner can make.
Hemet Insulation serves the full city and the surrounding valley, including San Jacinto, Banning, and Beaumont to the east, and Perris and Menifee to the west. If your home was built before 1990 and you have not had your insulation checked, we will come out and tell you exactly what is there, at no charge, with no obligation to hire us.
By appointment only, no walk-ins.
