Insulation Company in Murrieta, CA
Blown in insulation is the most common upgrade we install in Murrieta because so much of the city’s housing stock was built between 1985 and 2005 with original R-11 to R-19 fiberglass batts that have since settled, sagged, or blown aside under concrete tile roofs. The hot, dry inland climate of southwest Riverside County bakes attics to 140°F and higher in summer while winter nights drop into the 30s, and the fix is usually a fresh layer of loose fill blown to full depth across the attic floor. Placentia Insulation has served Murrieta since 2018, and we match the material to the job rather than the job to whatever we have on the truck.

Why Murrieta Homes Are Different
Murrieta sits in the hot, dry inland stretch of southwest Riverside County where summer highs routinely push past 100°F but winter nights drop near freezing. That true two-season swing makes insulation a year-round performance issue here, not just a summer one. The housing stock is overwhelmingly post-1985 master-planned tract construction: stucco on wood frame, concrete tile roofs, and large attached garages, built out heavily through the 1990s and early 2000s. Those original builds typically got R-11 to R-19 fiberglass batts in the attic and thin, poorly sealed flex duct runs through unconditioned spaces. Under the concrete tile roofs, attic batts sag and blow aside within 15 to 20 years, and flex duct gets cooked brittle from the radiant heat load. Our techs routinely find collapsed or separated duct runs in Murrieta attics even on houses that look fine from the living room. The dominant need is high-R blown-in upgrades plus duct insulation that survives the heat, not the retrofit knob-and-tube work you would see in older coastal cities.
Our Main Murrieta Services
Murrieta homeowners call us most about two things: getting their attic insulation up to current R-value standards and deciding whether spray foam makes sense for their specific roofline or wall assembly. Both services get their own dedicated pages, linked below.
Attic Insulation in Murrieta
Attic insulation in Murrieta usually means removing or topping off the original fiberglass batts that came with the house and blowing a fresh layer to R-38 or R-49 across the entire attic floor. On the big tract subdivisions spanning the 92562 and 92563 ZIP codes, we also look at the duct runs in the unconditioned attic, because cooked flex duct leaks the conditioned air you just paid to cool. One job, one contractor, no generalist in the attic guessing at air sealing. Attic Insulation in Murrieta covers the full scope, materials, and local pricing.
Spray Foam Insulation in Murrieta
Spray foam in Murrieta solves problems that fiberglass and cellulose cannot: sealing the roofline against radiant heat, air-sealing the building envelope, and insulating hard-to-reach spaces like the underside of a tile roof deck or the walls of a bonus room over the garage. We offer both open-cell and closed-cell chemistries through Icynene and Demilec, and we pick the foam based on the application, not on whatever is already loaded in the rig. Spray Foam Insulation in Murrieta walks through the options, the costs, and the signs that foam is the right call for your home.

Blown In Insulation in Murrieta
Blown in insulation is the workhorse retrofit for Murrieta’s post-1985 tract homes. The original attic batts in most of these houses were installed at R-11 to R-19, and after two decades under a concrete tile roof, they have sagged, compacted, and left bare patches across the attic floor. Blowing fresh loose fill over the top, or removing the old batts first, brings the attic to R-38 or R-49 and immediately flattens indoor temperatures between rooms. We pull from a full material library that includes GreenFiber cellulose and fiberglass loose fill, so the right product goes into the right house. For more on the method and the materials, see our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Your attic has settled, dusty fiberglass batts with visible gaps, or you can feel heat radiating down through the ceiling on summer afternoons.
What it costs in Murrieta
Cellulose blown-in insulation in Murrieta typically runs $1.50 to $2.80 per square foot installed, and most full attic jobs land between $1,800 and $3,400.
How we do it
We air-seal the attic floor penetrations, set the target R-value for your home, and blow dense-packed or loose-fill cellulose to a uniform depth across the entire attic.
Blown In Attic Insulation
Signs you need it
Second-floor rooms run noticeably hotter than the ground floor, and your AC runs longer than it should on days above 90°F.
What it costs in Murrieta
Blown in attic insulation in Murrieta typically costs $1,200 to $2,900 depending on attic size and whether old material is removed first.
How we do it
We remove or level the existing material, seal the attic bypasses, and blow the specified inches of loose fill to hit your target R-value with zero gaps.
Loose Fill Insulation
Signs you need it
Attic insulation is uneven, compressed under foot traffic, or missing entirely over half the ceiling area.
What it costs in Murrieta
Loose fill insulation in Murrieta runs $1.40 to $2.60 per square foot installed, with smaller attic spaces landing on the lower end of the range.
How we do it
We set the R-value goal, install depth markers around the attic, and blow loose fill evenly across every bay and corner until it reaches full depth.
What Blown In Insulation Costs in Murrieta
| Item | Typical range in Murrieta |
|---|---|
| Blown in attic insulation (full attic) | $1,200 – $2,900 |
| Cellulose blown-in (per sq ft installed) | $1.50 – $2.80 |
| Loose fill insulation (per sq ft installed) | $1.40 – $2.60 |
Which blow-in material performs best in Murrieta’s heat?
GreenFiber cellulose holds its position better than lightweight fiberglass in Murrieta’s hot, dry attics, and it fills odd corners and around trusses more completely. Fiberglass loose fill is lighter and works well over existing batts in houses where we top off rather than remove.
Can you blow insulation over my old attic batts?
In most Murrieta tract homes, yes. We level severely compressed or damaged batts first, then blow fresh material over them. If the old material is wet from a roof leak or full of rodent waste, removal comes first. Call (855) 773-6429 for an exact assessment.

Prices in Murrieta push toward the upper end when we have to remove collapsed or brittle flex duct first, when the attic is especially tight or low-slope, or when the roofline gets spray foam instead of the attic floor. You get a written, itemized price before any material hits the truck, and that number does not change unless we find something genuinely unexpected together.

Most Murrieta HOAs do not regulate interior insulation work, and attic insulation is almost never visible from the street, but some subdivisions with specific solar or tile-roof requirements ask for advance notice before any roof penetration. We are familiar with the common HOA notice processes in the big tracts and can tell you what to expect for your street.

What Murrieta Customers Say
"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
— Gilbert Ramirez"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."
— Veronica Guzman"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Rachel Sullivan
