Insulation Company in Adelanto, CA
Adelanto’s insulation problems don’t look like the ones in Victorville or Apple Valley. At nearly 2,900 feet in the Mojave High Desert, summers push past 108°F and winter nights dip below 28°F. Year after year, that 100-degree swing works on your attic and floor insulation until it stops doing its job. We’re Thistledown Attic Insulation, a Cedarwell-family company, and we install attic and spray foam insulation to the same written-price and clean-up standard on every Adelanto job. Call (909) 768-6501 and a live person answers, day or night.
Why Adelanto Homes Are Different
Adelanto has a housing stock pattern you won’t find in most of San Bernardino County. A large share of homes are manufactured or HUD-code units installed in the 1980s and 1990s. Those homes shipped with belly-pack insulation under the floor that has now been through thirty-plus years of Mojave thermal cycling. The material sags, tears, and pulls away from the chassis, leaving floor cavities open to desert air. We see it in volume in Adelanto’s manufactured-home parks, and it’s usually the single biggest energy leak in the house.
Site-built tract homes from that same era aren’t much better off. Most received R-19 attic insulation, which met code at the time but was never sized for a climate that hits 112°F in July and freezes hard in January. Add the wind that funnels through the Cajon and Summit Valley corridors, and you get air moving through attic bypasses and rim joists all year. In Adelanto, air-sealing isn’t an add-on. It’s the part of the job that makes the insulation work at all.
Our Main Adelanto Services
Adelanto homeowners call us about two jobs most often, and each has its own dedicated page with pricing and specifics.
Attic Insulation in Adelanto
Most Adelanto attics we open are holding compressed, thin, or uneven insulation that hasn’t been touched since the home was built. We remove what’s failing, air-seal the bypasses that let desert wind through, and install fresh material matched to the attic’s actual depth and the home’s duct layout. For manufactured homes, we also check the floor system, because that’s where Adelanto homes lose the most conditioned air. Products like Owens Corning and Johns Manville go in with shoe covers on our boots and drop cloths down your hallway. Full details are on the Attic Insulation in Adelanto page.
Spray Foam Insulation in Adelanto
Spray foam earns its cost in Adelanto because it air-seals while it insulates. That’s the combination this climate demands. In a site-built attic, closed-cell foam stops the stack effect that pulls 110° heat in and lets heated air out. On manufactured homes, foam can also work in floor cavities where belly-board has failed, sealing the chassis from wind-driven grit. We install Demilec and Icynene systems with the written price in your hand before any work starts. The full picture is on the Spray Foam Insulation in Adelanto page.

Adelanto prices run higher than Victorville or Apple Valley when the job involves a manufactured home’s failed belly-board, because removal and chassis re-fitting add labor. Deep attics with old wiring or ducts in the way also push costs up. Whatever the number, you get it in writing before our crew touches a rafter.
