Insulation Company in Murrieta Hot Springs, CA
Blown in insulation is the most common retrofit we install in Murrieta Hot Springs, and for good reason. Most homes in the 92563 ZIP were built in the 1990s and 2000s with thin fiberglass batts that have settled, compressed, or pulled away from the ceiling plane after two decades of 100°F-plus attic heat. Comfort Zone Insulation Co has served Murrieta Hot Springs since 2012, and we carry eight brands so the right material gets matched to your specific attic, wall cavity, or crawl space.

Why Murrieta Hot Springs Homes Are Different
Murrieta Hot Springs sits deep in the Temecula Valley’s inland heat zone, where summer highs routinely push past 100°F and the marine layer never reaches this far east. That changes what insulation needs to do here. Coastal homes worry about holding heat in; Murrieta Hot Springs homes worry about blocking brutal radiant attic heat and keeping air conditioning from fighting the sun. We regularly see attics in this area running 40 to 50 degrees hotter than the living space below on a July afternoon.
The daily temperature swing matters too. Cool desert nights follow scorching afternoons, so insulation has to handle both directions of heat transfer. Homes built in the 1990s and 2000s here are almost always wood-frame stucco on standard tract lots, and the original batt insulation in those attics has often compressed to half its labeled R-value. In this inland valley heat, we also see a failure pattern you won’t find in San Diego or Orange County: sun-baked, disintegrated radiant barrier foil that crumbles when touched, paired with sagging batt that has pulled back from the ceiling plane. Attic ventilation and radiant barriers matter as much as batt depth in Murrieta Hot Springs.
Our Main Murrieta Hot Springs Services
Most Murrieta Hot Springs homeowners who call us are dealing with one of two problems: an attic that’s acting like an oven and cooking the rooms below it, or air leaks that let conditioned air escape and dust blow in. Here’s how we address both.
Attic Insulation in Murrieta Hot Springs
Attic insulation is the single highest-impact zone in a Murrieta Hot Springs home. In houses built in the 1990s and 2000s, we typically find original batt that’s settled to R-19 or less, plus gaps around recessed lights, plumbing vents, and partition walls where hot attic air pours into the living space. We remove or top the old material, air-seal the ceiling plane, and bring the attic up to R-38 or R-49 depending on your home and budget. In this inland heat, we also check for failed radiant barrier and recommend ventilation upgrades where the soffit or ridge vents are undersized.

Spray Foam Insulation in Murrieta Hot Springs
Spray foam is the best answer for Murrieta Hot Springs homes where air leakage, not just thin insulation, is the real problem. Closed-cell foam air-seals and insulates in one step, which is especially valuable in the valley’s hot, dusty climate where outside air carries heat and fine dust into the house through every crack. We install Icynene and Demilec open- and closed-cell systems, and we choose the product based on your roof assembly, attic design, and whether you want a conditioned attic. Open-cell foam also works well for interior sound control in master-planned communities with close lot lines. See the full breakdown here: Spray Foam Insulation in Murrieta Hot Springs.

Blown In Insulation in Murrieta Hot Springs
Blown in insulation is the workhorse retrofit for Murrieta Hot Springs attics. Two decades of inland Riverside County heat compresses standard batt until it’s barely doing its job, and blowing new insulation over or in place of that old material is the fastest, most cost-effective way to restore thermal performance. We install Blown In Insulation using dense-pack and loose-fill methods, and in this climate we almost always pair attic blow-ins with air sealing so you’re not just adding fluff on top of leaks.

Cellulose attic blow-in in Murrieta Hot Springs typically runs $1.20 – $2.00 per square foot depending on depth and whether we remove the old material first.

Is blown in insulation worth it in Murrieta Hot Springs heat?
Yes. In this inland valley climate, restoring attic R-value and adding air sealing typically cuts cooling costs noticeably because your AC stops fighting 130°F attic air. Most homeowners see comfort and bill improvements the same season.
Can you blow insulation over old batts?
In most Murrieta Hot Springs homes we recommend removing or at least topping the old, heat-compressed batt before blowing new material. That gives you a clean, even layer and lets us seal the air leaks underneath. Call (855) 341-7856 for a site-specific answer.

What Murrieta Hot Springs Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Vivian Kim"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Dustin Sullivan"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
