Insulation Company in Murrieta, CA
Blown in insulation solves the most common comfort problem we see across Murrieta: attic floors holding original fiberglass batts from the 1990s that have settled, compressed, and stopped doing their job. We’re Shelter Insulation, and we’ve served Murrieta since 2016 with a full range of insulation materials and methods, including blown-in cellulose and fiberglass, spray foam, and batt insulation. When a Murrieta homeowner calls us about rooms that won’t hold temperature, the fix is usually in the attic. Call us at (855) 341-3373 for a straight answer and a free estimate.
Why Murrieta Homes Are Different
Murrieta sits in the inland sunbelt of Southwest Riverside County, where summer afternoons push past 100°F and winter nights drop near freezing. That’s a nearly 50-degree annual swing, and it punishes under-insulated homes. Most of Murrieta’s housing stock went up during the 1990s and 2000s boom, when the city grew from roughly 17,000 residents to over 100,000. Those master-planned tract homes were built quickly, and many still carry original R-11 to R-19 attic batts that are now compressed, settled, or degrading. Tile roofs, the standard across Murrieta, trap heat in the attic and accelerate the breakdown of insulation and radiant barrier foil. The dry climate means we rarely deal with moisture-driven insulation failure, but fierce UV exposure and heat degradation are constant. In the older 1980s and 1990s tracts around ZIP 92562, near the historic downtown core, we routinely find original builder-grade attic batts settled to half their rated depth, with failing radiant barrier stretched over the top. Newer 92563 subdivisions to the east often just need added blow-in to hit current Title 24-era efficiency targets. The result is a neighborhood-by-neighborhood upgrade wave, not scattered one-off jobs.
Our Main Murrieta Services
These are the two services Murrieta homeowners call us about most. Each has its own dedicated page with full local detail.
Attic Insulation in Murrieta
Most Murrieta attics we inspect have insulation that’s under-performing for one of two reasons: age-related settling or builder-grade installation from the start. Tile roofs amplify the heat load, so an attic that’s insulated to current code makes a dramatic difference in both summer cooling bills and winter warmth. We remove old, compressed material when needed, air-seal the attic floor, and install fresh insulation matched to the home’s construction and the homeowner’s goals. In Murrieta’s 1980s-2000s tract homes, this often means bringing R-11 or R-19 attics up to R-38 or better. Read the full breakdown here: Attic Insulation in Murrieta.
Spray Foam Insulation in Murrieta
Spray foam solves a different problem than blown-in or batt insulation: it seals the building envelope as well as insulates it. In a hot inland climate like Murrieta’s, that sealing matters because it stops the stack effect that pulls hot attic air down into living spaces. We install open-cell and closed-cell foam from Icynene and Demilec, two of the most widely specified brands in high-performance residential building. For Murrieta homes with vaulted ceilings, knee walls, or attics that double as storage or HVAC platform space, spray foam is often the right call.

Blown In Insulation in Murrieta
Blown in insulation is the fastest, most effective retrofit for a Murrieta attic that’s under-insulated. Because most of the city’s housing was built in the 1990s and 2000s with minimal attic insulation, we’re now seeing a wave of attics where original batts have settled and compressed, leaving rooms that bake in August and chill in January. Blown-in insulation reaches where batts can’t: it fills gaps around framing, plumbing vents, and electrical runs, creating a continuous thermal blanket across the attic floor. We install both cellulose and fiberglass loose fill, and the service is available as a standalone job or combined with attic air sealing for maximum effect. The full service is detailed on our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Rooms that run 8 to 10 degrees warmer than the rest of the house in summer are a strong signal your attic insulation has settled and needs a dense, continuous fill like cellulose.
What it costs in Murrieta
Blown-in cellulose for a typical Murrieta attic runs $1,200 to $2,800, depending on the square footage and how much old material we need to remove or work around.
How we do it
We prep the attic, air-seal bypasses around penetrations, and blow GreenFiber cellulose to the target depth and R-value using calibrated equipment.
Blown In Attic Insulation
Signs you need it
If your upstairs ceilings feel warm to the touch in summer or your attic floor insulation is visibly below the top of the floor joists, you need more attic coverage now.
What it costs in Murrieta
Blown-in attic insulation in Murrieta typically costs between $900 and $2,500, with insulated attics seeing the biggest energy savings in the peak summer months.
How we do it
We measure the existing depth, calculate the R-value gap, then blow fiberglass or cellulose to reach R-38 or higher across the entire attic floor.
Blown In Cellulose Insulation
Signs you need it
Drafty hallways, high cooling bills, and uneven temperatures between rooms are clear signs your attic needs a dense, continuous blown-in cellulose layer.
What it costs in Murrieta
Expect to pay $1,200 to $2,800 for blown-in cellulose in a standard Murrieta tract home attic, with thicker depths and removed old material at the upper end.
How we do it
We run a hose into the attic, calibrate the machine to the right density, and build the cellulose up to the R-value your home needs.
Blown In Fiberglass Insulation
Signs you need it
If you can see bare drywall or plywood between scattered batts in your attic, blown-in fiberglass will fill those gaps and create a uniform thermal layer.
What it costs in Murrieta
Blown-in fiberglass for a Murrieta attic usually runs $900 to $2,500, with larger attics and deeper fills pushing the total toward the upper range.
How we do it
We blow unbonded fiberglass to the specified depth, using baffles to keep soffit vents clear and insulation dams to protect can lights and other fixtures.
Loose Fill Insulation
Signs you need it
Attics with original builder-grade batts that have compressed to half their rated depth are prime candidates for a loose fill top-up or full replacement.
What it costs in Murrieta
Loose fill insulation in Murrieta costs $900 to $2,800 depending on material choice, attic size, and whether we remove old settled insulation first.
How we do it
We either top up over existing insulation or remove degraded material first, then blow loose fill to a smooth, consistent depth for full coverage.
What Blown In Insulation Costs in Murrieta
| Item | Typical range in Murrieta |
|---|---|
| Blown-in fiberglass attic insulation | $900 – $2,500 |
| Blown-in cellulose attic insulation | $1,200 – $2,800 |
| Loose fill insulation (attic) | $900 – $2,800 |
Is blown-in insulation worth the cost in Murrieta’s climate?
Yes, especially with 100°F summer days. A properly insulated attic keeps your air conditioning from running constantly, and most Murrieta homeowners notice lower cooling bills the first summer after installation. Call (855) 341-3373 for a specific quote.
Can you blow insulation into an attic without removing the old batts?
Often, yes. If the existing batts are dry and not compressed, we can blow loose fill directly over them to raise the R-value. If they’re degraded or settled, removal is the better path. We’ll inspect and tell you straight.
Brands We Service in Murrieta
We carry eight manufacturer brands spanning fiberglass, mineral wool, spray foam, and cellulose. In Murrieta, the biggest demand is for Owens Corning fiberglass and GreenFiber cellulose in attics, plus Icynene and Demilec spray foam for sealing and high-performance retrofits. Our parts and material relationships mean most Murrieta jobs can be scheduled within days, not weeks. See our brands for the full lineup.

FAQs About Insulation Company in Murrieta
We typically schedule Murrieta estimates within two to three business days. For an attic that’s actively making a room unbearable in summer, call (855) 341-3373 and we’ll do our best to see you sooner. The estimate is free and comes with a written price.
Attic insulation and spray foam work happens entirely inside your home, so HOA approval is rarely required. Murrieta HOAs govern exterior changes, not interior attic projects. If you have a specific restriction in your CC&Rs, we can work around it once you confirm.
Tile roofs trap heat and make attic access tighter, which is exactly why we see so much heat-degraded insulation under Murrieta’s tile-roof tract homes. Our crews are used to working in low-clearance attics and around tile roof framing, and we’ll tell you what’s possible before we start.
