Insulation Company in Murrieta, CA
Thistledown Attic Insulation helps Murrieta homeowners fix attics that were under-insulated the day the drywall went up. Most homes here were tract-built between 1990 and 2015, when Title 24 energy standards were far looser than today, and that original fiberglass has been settling, compressing, and failing quietly for 15 to 30 years. We inspect what’s actually up there, write you a firm number before any work begins, and treat your hallway like our own. Call (909) 768-6501 to schedule a look.
Why Murrieta Homes Are Different
Murrieta sits in an inland valley at roughly 1,000 feet elevation, which means the attic is working against a wider temperature swing than almost anywhere else in Southern California. Summer afternoons push attic temperatures past 150°F while winter nights regularly drop into the mid-30s. A coastal home in Carlsbad never asks its insulation to handle both extremes. Yours does, every single year.
The housing stock compounds that stress. Murrieta was one of the fastest-growing cities in the entire country through the 1990s and 2000s, and builders put up thousands of two-story tract homes to R-19 or R-30 attic minimums, the bar at the time. When you add years of HVAC service techs moving through tight attic spaces, those batts get shoved aside, compressed, or left with bare spots above bedrooms. Along the Clinton Keith and Murrieta Hot Springs Road corridors especially, we find the insulation around air handlers crushed or missing altogether. It’s a pattern so consistent in that construction vintage that we expect to see it before we open the hatch. The good news is that a retrofit here does more than it would in a milder climate, because Murrieta’s dual-season loads make every inch of added R-value pay you back in both August and January.
Our Main Murrieta Services
Most Murrieta homeowners reach out to us about one of two things: getting the attic back up to where it should be, or sealing and insulating with spray foam where standard batts keep underperforming.
Attic Insulation in Murrieta
Attic insulation work in Murrieta usually starts with finding the gaps: the crushed batts behind the air handler, the bare spots over the garage, the settled areas that have dropped from R-30 to something closer to R-12. We remove what’s failing, air-seal the penetrations, and install fresh material sized to your attic and your home’s orientation. In these inland-valley summers, getting the attic right is the single highest-impact change most Murrieta homeowners can make. Attic Insulation in Murrieta has the full breakdown, including what we typically find in specific neighborhoods.
Spray Foam Insulation in Murrieta
Spray foam earns its keep in Murrieta’s low-pitch attics, where cramped spaces and ductwork make traditional batts hard to fit well. Closed-cell foam air-seals and insulates in one pass, and it holds its R-value even when summer heat pushes an attic past 140°F. It’s the right call for homes where the HVAC equipment lives in the attic and the ductwork is leaking conditioned air into a space you never use. Spray Foam Insulation in Murrieta explains what to expect from the job.
