Insulation Company in Murrieta, CA
Blown in insulation is the retrofit Murrieta homeowners call about most, and for good reason: attics here routinely hit 150°F in summer, and the tract homes built across 92562, 92563, and 92564 between the late 1980s and early 2000s often still carry original R-11 to R-19 attic insulation that has settled, compacted, or been torn up by rodents from the nearby foothills. Homestead Insulation Co has served Murrieta since 2012, and we install blown in cellulose, blown in fiberglass, spray foam, and batt insulation from eight trusted manufacturers.

Why Murrieta Homes Are Different
Murrieta sits in a hot inland valley where summer days regularly cross 100°F, and the unvented tile roofs common across the city trap that heat and push attic temperatures well past what most insulation was ever designed to handle. Homes here are overwhelmingly two-story stucco tract builds from the late 1980s through the 2000s, and nearly all of them left the builder with attic insulation that met code at the time but falls far short of what today’s energy costs demand. The original R-11 to R-19 in these attics has settled over two or three decades, and in neighborhoods near the foothills, rats and mice have tunneled through it, leaving bare patches that let conditioned air pour out through the ceiling.
There is also a compliance angle specific to California. Murrieta homeowners who renovate, add square footage, or pull permits for other work now face Title 24 energy requirements that make attic insulation and radiant barriers a code item, not an optional upgrade. When a home inspector or appraiser flags insufficient attic insulation before a sale, the fix usually lands on the seller’s desk fast. We see that call every week. The good news is that the uniform construction of Murrieta’s subdivisions makes blown in attic insulation a straightforward, high-impact retrofit: the attic access is predictable, the framing is consistent, and the payoff in lower cooling bills shows up almost immediately.
Our Main Murrieta Services
Most Murrieta homeowners reach out to us about two services: bringing attic insulation up to current standards, and using spray foam to seal the hard-to-reach spaces where air leaks drive energy waste. Both are covered here at a high level, with dedicated Murrieta pages that go deeper.
Attic Insulation in Murrieta
When we open an attic in Murrieta, the most common scene is settled fiberglass batts compressed to a fraction of their original depth, with gaps around light fixtures, attic hatches, and the top plates of interior walls. Add in the heat that tile roofs hold, and the fix usually involves air-sealing those gaps first, then installing high-R insulation matched to the home’s ceiling framing and the attic’s ventilation setup. For homes with unvented tile roofs, a radiant barrier is often part of the conversation, because reflecting heat away before it gets absorbed into the insulation is what actually moves the needle on cooling bills here. That is the kind of detail covered on our Attic Insulation in Murrieta page.
Spray Foam Insulation in Murrieta
Spray foam earns its place in Murrieta when a home has irregular framing, a bonus room over the garage, or a knee-wall attic that batts and blown in material just cannot seal. Closed-cell foam from Demilec or Icynene acts as both insulation and an air barrier, which matters in a climate where a small air leak carries 100°F air into the house all summer. The uninsulated garage ceilings in many older Murrieta homes are a prime candidate, especially when the garage sits under a bedroom that never seems to cool off. Full details and local pricing are on our Spray Foam Insulation in Murrieta page.

Blown In Insulation in Murrieta
Blown in insulation is the most common retrofit we install in Murrieta because it matches the housing stock perfectly: fast coverage over settled batts, full fill around trusses and ceiling joists, and the ability to reach an R-38 or R-49 depth that makes a real dent in summer cooling loads. In homes built across the 92562, 92563, and 92564 ZIP codes, the original attic insulation is almost always underperforming, and blowing in fresh Blown In Insulation over the top, after air-sealing and any needed radiant barrier work, is the fastest path to a cooler second floor and lower summer electric bills.
Cellulose Insulation
Signs you need it
Your attic insulation has settled, shows signs of rodent traffic, or you can see ceiling joists poking through in a home built in the 1990s or 2000s.
What it costs in Murrieta
Blown in cellulose in Murrieta typically runs $1.20 to $2.00 per square foot installed, with attic-only upgrades ranging from $1,800 to $4,300 depending on depth and access.

We air-seal the attic floor, run the GreenFiber cellulose through a calibrated blower to the specified depth for your ceiling assembly, and verify R-value with depth markers before we pack up.
Blown In Attic Insulation
Signs you need it
The second floor of your Murrieta home runs 8 to 12 degrees hotter than the first floor in summer, or your attic hatch feels warm to the touch on a mild evening.
What it costs in Murrieta
Blown in attic insulation in Murrieta averages $1,500 to $3,800 for a typical 1,200 to 2,500 square foot attic when bringing depth up to current R-38 or R-49 levels.
How we do it
We locate and seal every penetration through the attic floor, install baffles where the eaves meet the roofline so ventilation stays clear, then blow insulation to an even, measured depth across the entire attic.

Can blown in insulation really lower my summer cooling bill in Murrieta?
Yes. Bringing a Murrieta attic from R-11 or R-19 up to R-38 or R-49 reduces the heat radiating through your ceiling, which is the single biggest driver of summer cooling load in this climate. Call (844) 820-1136 for a free estimate.

Most blown in attic insulation jobs in Murrieta finish in one day, usually 3 to 6 hours depending on attic size, access, and how much air-sealing is needed first. Call (844) 820-1136 to schedule.

What pushes price up in Murrieta is usually attic access: a tight scuttle in a hallway closet takes more setup than a pull-down stair, and a low-pitch tile roof means more work near the eaves. What does not change is the price you are quoted; Homestead Insulation Co gives upfront, line-item pricing before any work starts.

— Brandon Park"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
