Insulation Company in Murrieta, CA
Murrieta homes lose far more energy through under-insulated attics than most homeowners realize. We specialize in blown in insulation for Murrieta’s 1990s and 2000s tract homes, where original builder-grade R-19 attic insulation has settled, compressed, and stopped doing its job against Temecula Valley summers that regularly push past 100°F. If your upstairs rooms run 8 to 12 degrees warmer than downstairs in July, the fix usually starts in the attic. Call Maple Insulation Co at (855) 341-6045 and we’ll assess what’s actually up there before recommending anything.
Why Murrieta Homes Are Different
Murrieta sits inland in the Temecula Valley, where summer heat builds and lingers. Air conditioners work double shifts from June through October, and the sun beats directly onto stucco exteriors and composition shingle roofs. Yet most of Murrieta’s housing stock was framed during the 1990s and early 2000s construction boom, when builders met minimum code requirements rather than performance goals. That means R-19 fiberglass batts or a thin layer of loose fill in the attic, minimal wall insulation, and dozens of unsealed penetrations at recessed lights, top plates, and plumbing stacks. Twenty-plus years of thermal cycling in 100-degree summers followed by near-freezing winter nights has settled that original material well below its rated R-value. The real job in Murrieta is not repairing damaged insulation. It’s retrofitting an entire thermal envelope that was never designed for today’s energy costs or comfort expectations.
Our Main Murrieta Services
Two jobs account for most of the calls we run in Murrieta: full attic insulation upgrades and spray foam applications for specific problem areas. Both address heat gain first, but they work differently and fit different attics.
Attic Insulation in Murrieta
For most Murrieta tract homes, the attic is where the money leaks. Original blown fiberglass has settled to half its intended depth in many 92562, 92563, and 92564 attics, leaving ceilings that radiate heat into living spaces by mid-afternoon. We remove or top off the old material, air seal the attic floor, and bring the assembly to current code levels. For a closer look at how we handle full attic retrofits in this climate, see our Attic Insulation in Murrieta page.
Spray Foam Insulation in Murrieta
Spray foam earns its cost in Murrieta when air leakage is the primary culprit. Recessed light housings, HVAC chases, and top plates create convection currents that pull conditioned air out of living spaces and draw 140-degree attic air in. Closed-cell foam seals those paths while adding R-value in a single pass. We carry both Icynene and Demilec product lines so the recommendation fits the attic geometry and budget rather than our inventory. Details on applications and performance are on our Spray Foam Insulation in Murrieta page.

Blown In Insulation in Murrieta
Blown in insulation is the most practical retrofit for Murrieta’s aging tract homes because it installs quickly over existing attic floors and reaches the edges, corners, and odd framing cavities that batts miss. In 92562 and 92563 especially, we see attics where the original blown fiberglass has settled to R-10 or worse while the homeowner pays to air condition the attic. Our crews install Blown In Insulation using coverage charts that account for Murrieta’s Climate Zone 3B rating, so the installed depth matches the labeled R-value after settling, not before. GreenFiber cellulose is a strong fit here: it fills dense, reduces airflow through the insulation layer itself, and carries recycled content that appeals to Murrieta homeowners who think about material choices.
Cellulose Insulation
Signs you need it
Your attic insulation sits below the top of the ceiling joists and your upstairs runs warmer than your downstairs by more than a few degrees on hot afternoons.
What it costs in Murrieta
Cellulose blown in insulation in Murrieta typically runs $1.00 – $1.50 per square foot installed, depending on depth and access.
How we do it
We air seal the attic floor, set depth markers at the target R-value, and blow GreenFiber cellulose to a consistent density across the entire attic.
Blown In Attic Insulation
Signs you need it
Your attic has bare spots, compressed fiberglass, or original 1990s material that has settled two to four inches below the joist tops.
What it costs in Murrieta
Blown in attic insulation in Murrieta ranges from $1,000 to $2,700 for an average 1,500 to 2,500 square foot home, with attic access and ceiling height affecting the final number.
How we do it
We run a hose from a truck-mounted blower, lay material to the depth your R-value target requires, and verify coverage with marked depth gauges before we leave.
Blown In Fiberglass Insulation
Signs you need it
You want a non-flammable, lightweight retrofit material and your existing fiberglass has flattened or shifted away from the eaves.
What it costs in Murrieta
Blown in fiberglass typically costs $0.80 – $1.10 per square foot installed in Murrieta attics, with final pricing set by depth and square footage.
How we do it
We install Owens Corning or Johns Manville loose fiberglass to the manufacturer’s density chart, using baffles at the eaves to preserve soffit ventilation.
Loose Fill Insulation
Signs you need it
Your attic has irregular joist spacing, low clearance, or obstacles like trusses and cross-bracing that make batt installation inefficient.
What it costs in Murrieta
Loose fill insulation in Murrieta runs $0.70 – $1.50 per square foot installed, depending on the material selected and the target depth.
How we do it
We select the loose fill material that matches your attic’s air sealing needs, blow it to uniform depth, and level around obstacles for consistent coverage.
