Serving Murrieta, CA and surrounding areas. (951) 574-0182

Murrieta Insulation is a licensed insulation contractor serving Hemet, CA with blown-in insulation, attic upgrades, air sealing, and spray foam for ranch homes, senior communities, and newer Hemet neighborhoods. We reply within one business day and provide a free on-site estimate on every job.

Hemet's 1950s through 1980s ranch homes were built to insulation standards far below what California recommends today, and blown-in is the most efficient way to upgrade them. Our blown-in insulation service fills every corner of your attic evenly — including the irregular spaces around HVAC equipment and structural bracing — without requiring the attic to be emptied first when the existing material is still in good condition.
Hemet sits at about 1,600 feet elevation, which makes summer temperatures hotter and winter nights colder than most of coastal Southern California. Your attic works hard in both directions — losing heat in January and gaining it in July — so getting to the R-38 to R-60 range recommended for this climate zone pays off year-round, not just in summer.
Many Hemet homes built in the 1950s and 1960s still have original insulation that has been contaminated by rodents, saturated by a roof leak, or simply aged past its useful life. Installing new material on top of compromised insulation does not fix the problem — the old material needs to come out first, and we handle that safely and completely before the replacement goes in.
The same gaps around recessed lights, plumbing stacks, and HVAC runs that let conditioned air escape in summer pull cold air in during Hemet's winter nights — and both problems raise your energy bills. Sealing those penetrations before blown-in material goes in is what separates an insulation job that performs from one that barely moves the needle on your utility bills.
For Hemet homeowners who want to address the whole envelope — attic, walls, and any crawl space — in a single project, a full home insulation assessment identifies where heat gain and loss are greatest and prioritizes the work accordingly. This approach makes sense for homes on fixed budgets where getting the most return from each dollar spent matters most.
Hemet's older ranch homes have stucco-clad wood-framed walls where the cavities were either under-insulated at construction or have never been touched. Retrofit wall insulation fills those cavities through small drilled holes — patched afterward — without gutting the interior, which is the practical choice for a home you plan to remain in.
Hemet is a city of about 90,000 people in the San Jacinto Valley, and its housing stock tells the story of several distinct growth eras. The oldest neighborhoods near downtown have homes from the 1950s and 1960s — many on slab foundations, finished in stucco, with original attic insulation that has had six or seven decades to degrade. The 1970s and 1980s added another wave of ranch-style homes that were better insulated at the time but are still well below what California's current energy code recommends. A significant share of Hemet's housing is also manufactured homes and age-restricted communities, which have their own insulation needs and materials.
The climate here does not forgive poor insulation in either season. Hemet sits at about 1,600 feet elevation — high enough that summer temperatures regularly exceed 100°F while winter nights can drop below freezing between December and February. That freeze-thaw cycle, mild by northern standards but real enough to crack concrete and stress pipe connections, is something coastal California homeowners rarely face. In summer, the combination of high heat, low humidity, and over 280 sunny days per year breaks down roofing materials and exterior coatings faster than in cooler climates, and it puts relentless pressure on under-insulated attics every afternoon from June through September.
Budget consciousness matters in Hemet more than in many surrounding cities. A large share of homeowners here are retirees or first-time buyers who made the move inland specifically because housing was affordable. That means the payback timeline on an insulation upgrade matters, and so does an honest assessment of what is and is not worth spending on. We do not recommend work that a home does not need, and we apply for available rebates through SoCalGas and SCE on every qualifying job.
Our crew works regularly in Hemet, coordinating permitted jobs through the City of Hemet and serving the full range of property types the city has — from slab-foundation ranch homes in the older neighborhoods to manufactured housing communities where insulation specifications and access points differ from site-built construction. The city's large senior population means we often work with homeowners on fixed incomes, and we approach every estimate with that in mind: clear pricing, no upsells, and honest recommendations about what will and will not make a measurable difference.
Hemet Valley Mall and the Florida Avenue corridor are commercial landmarks most Hemet residents orient by, and the residential neighborhoods that surround those corridors give us a clear picture of the city's housing layers. The older streets west of downtown tend to have the most original insulation still in place; the neighborhoods near Diamond Valley Lake to the south are newer and often better starting points. We assess each home on its own — the quote reflects what we actually found, not a standard estimate for the neighborhood.
We serve the wider San Jacinto Valley from Hemet. Homeowners in San Jacinto just to the east face the same climate and housing-age dynamics, and we cover that city regularly. We also work in Moreno Valley to the north, where the Inland Empire's growth brought a different vintage of housing stock but comparable climate pressure on attic insulation.
Reach us by phone or through the contact form and we will respond within one business day. We ask a few basic questions — your home's age, approximate size, and what's driving the call — so we arrive prepared with the right materials and no wasted time.
We access your attic and check the current depth and condition of existing insulation — including any signs of rodent activity, moisture damage, or air gaps around penetrations. You receive a written estimate with a clear breakdown of what is included and what it will cost before we ask you to commit to anything.
The crew stages equipment in your driveway or garage and works through the attic hatch. Air sealing happens first, then blown-in material goes in to the depth confirmed in your estimate. Most single-story Hemet homes are done in one day, and you can remain at home throughout the work.
Once the work is complete, we walk you through what was installed, show the depth markers confirming the material reached its target thickness, and remove all equipment and debris before leaving. Photos from inside the attic are available on request.
We serve homeowners throughout Hemet — from the older neighborhoods near downtown to the streets near Diamond Valley Lake. No pressure, no obligation, just an honest assessment and a written price.
(951) 574-0182Hemet is a city of about 90,000 people in the San Jacinto Valley in Riverside County, about 90 miles east of Los Angeles and 30 miles from Palm Springs. Long known as a retirement destination, Hemet has a higher share of senior residents than most California cities of its size. The city is home to Hemet Valley Mall — the main retail hub for the valley — and is perhaps most distinctively known for the Ramona Outdoor Play, an annual outdoor drama that has run in the hills above the city since 1923 and is one of the longest-running outdoor theatrical productions in the United States. The surrounding area includes Diamond Valley Lake to the south, the largest reservoir in Southern California.
The housing stock reflects Hemet's growth across multiple eras: postwar bungalows and ranch homes from the 1950s and 1960s fill the older neighborhoods near downtown, while the 1970s and 1980s added larger subdivisions of stucco-clad single-story homes throughout the city. Manufactured housing communities and age-restricted developments make up a meaningful share of the total — a characteristic that distinguishes Hemet from most neighboring cities. Newer construction from the 2000s and 2010s sits on the city's outer edges, built on slightly different lot sizes but with the same slab-foundation construction that is standard throughout the valley.
Our service area extends across the valley from Hemet. We serve San Jacinto to the east, where the climate and housing age are nearly identical, and Menifee to the southwest — a faster-growing city with a distinct mix of Sun City-era homes and newer master-planned communities.
