Insulation Company in Murrieta, CA
Blown in insulation is the most common retrofit we perform in Murrieta, and for good reason: most homes here were built between the late 1980s and mid-2000s, and the original attic insulation has settled to a fraction of its installed depth. Summer attic temperatures in Murrieta routinely exceed 140°F, and when insulation sits below the ceiling joists, your air conditioner runs longer just to hold a set temperature. Hearthside Insulation is a dedicated insulation contractor serving Murrieta since 2016, focused entirely on matching the right material to the home rather than pushing one product line. Call us at (877) 265-4871 and we’ll tell you honestly what your attic actually needs.
Why Murrieta Homes Are Different
Murrieta sits in a wind-swept inland valley where summer heat regularly pushes past 100°F and Santa Ana winds strip attic insulation and dry out weatherstripping. Insulation here is as much about wind and radiant-heat defense as it is about cold-weather R-value. The city’s burst of 1990s to 2000s master-planned development means whole tracts share the same builder-grade attic insulation now 20-plus years old and settling well below modern Title 24 requirements. That is a rare, city-wide retrofit opportunity you do not get in older, patchier cities.
Walk through neighborhoods off the 215 corridor and you will see the same pattern: wood-frame construction, attached garages, vaulted ceilings, and attic insulation that has compressed to roughly half its original depth. Techs working in Murrieta routinely find attics sitting at R-11 to R-13 when Title 24 now calls for far more. The telltale sign is insulation visibly below the top of the ceiling joists, with sun-baked, compacted patches under roof vents. The dry inland air also dries out caulk and weatherstripping faster than in coastal cities, so air sealing is not optional here. It is the first thing we check.
Our Main Murrieta Services
The two services Murrieta homeowners call us about most are attic insulation and spray foam insulation. Each page covers pricing, signs, and what makes the job different in this climate.
Attic Insulation in Murrieta
Attic insulation in Murrieta is a retrofit job on homes where builder-grade fiberglass or cellulose has settled below the joists. We assess current depth, check for Santa Ana wind intrusion, and recommend either blown-in material to bring the attic up to current Title 24 levels or batt replacement where the roof deck shows radiant-heat stress. Vaulted ceilings and attached garages common in local tract homes create thermal-bypass points that a simple top-up will not fix; those need air sealing as part of the job. Read our full page on Attic Insulation in Murrieta for pricing and signs specific to this area.
Spray Foam Insulation in Murrieta
Spray foam in Murrieta is most often specified for rim joists, crawlspaces, and vaulted-ceiling cavities where traditional batts or blown-in material cannot stop the hot, dry air moving through the building envelope. Because Hearthside carries both Icynene and Demilec systems, we can compare open-cell and closed-cell on the same job and recommend based on whether the goal is air sealing, moisture resistance, or maximum R-value per inch. Murrieta’s extreme attic temperatures make closed-cell a common recommendation for roof decks. See our page on Spray Foam Insulation in Murrieta for the full breakdown.

Blown In Insulation in Murrieta
Blown in insulation in Murrieta is the fastest, most cost-effective way to restore attic thermal performance on 1990s and 2000s tract homes where the original material has settled or compacted. Most attics we inspect in Murrieta sit between R-11 and R-13 when the home is 20-plus years old, and many homeowners notice the problem first as upstairs rooms that will not hold temperature during summer afternoons. We install blown in insulation from brands including GreenFiber and Owens Corning, matched to the cavity and the performance goal rather than whatever is on the truck. Read more about the method on our Blown In Insulation service page, or call (877) 265-4871 for a Murrieta-specific quote.
Cellulose Insulation
Signs you need it
You see insulation below the top of the ceiling joists in your attic, and your upstairs rooms gain heat fast in the afternoon while the AC runs almost constantly.
What it costs in Murrieta
Designer cellulose insulation in Murrieta typically costs $60 to $100 per 1,000 sq ft of installed material, depending on the R-value we target and the condition of the existing attic.
How we do it
We air-seal the attic floor penetrations, then machine-blow GreenFiber cellulose to the specified depth and density, verified with a ruler in multiple spots across the attic.
Blown In Attic Insulation
Signs you need it
Your energy bills climb every summer, rooms over the garage never get comfortable, and the attic insulation looks patchy, compacted, or discolored under the roof vents.
What it costs in Murrieta
Blown in attic insulation over an existing settled layer in Murrieta typically runs $600 to $1,300 for a standard 1,500 sq ft attic, depending on the final R-value and access.
How we do it
We remove or level the old material where needed, seal bypasses around can lights, plumbing stacks, and top plates, then blow fresh material to the target depth across the attic floor.
What Blown In Insulation Costs in Murrieta
| Item | Typical range in Murrieta |
|---|---|
| Blown in attic insulation (existing 1,500 sq ft attic) | $600 to $1,300 |
| Designer cellulose insulation (per 1,000 sq ft) | $60 to $100 |
| Full attic air sealing plus blown in insulation | $1,500 to $3,500 |
These are ballpark figures. The final number in Murrieta depends on attic access, how much old material we need to remove, whether the home has vaulted ceilings or attached-garage thermal bypasses, and the R-value you want to reach.
Can you blow insulation over old, settled insulation in Murrieta?
Yes, if the old material is dry and not infested or moldy. We level the settled layer, air-seal the attic floor, then blow new material on top to reach the target R-value. Call (877) 265-4871 for an attic inspection.
How long does blown in insulation take in a Murrieta home?
Most Murrieta attics are done in half a day, including setup and cleanup. Larger homes with vaulted ceilings or air-sealing work may take a full day. We schedule around your availability, not the other way around.

Hearthside quotes a fixed price before work begins, so the number we give you is the number on the invoice.

What Murrieta Customers Say
"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."
— Angela Nguyen"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Sofia Delgado"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
— Nathan Meyer
