Insulation Company in Oak Hills, CA
Blown in insulation is the retrofit workhorse for Oak Hills homes, and for good reason: most houses here were built before modern energy codes, with original thin batts or bare plywood in the attic. We’re North Tustin Insulation, and we’ve served Oak Hills since 2011. Our crews know what a high-desert attic actually holds: baked-out fiberglass, gaps around exposed ductwork, and framing that never matches the blueprint. If your cooling bill spikes every July and your heater runs nonstop in January, call (877) 265-5712 for a free estimate. We carry eight insulation brands and match the material to your home, not the other way around.
Why Oak Hills Homes Are Different
Oak Hills sits in the Mojave high desert, where summer afternoons routinely push past 100°F and winter nights drop below freezing. That swing is brutal on any home, and it’s especially hard on the older, rural, and self-built houses that make up much of the local stock. Many of these properties went up with whatever insulation was cheapest at the time, or none at all in some attic bays. Add exposed ductwork, non-standard framing, and large lots with full sun exposure, and you get attics that hit 150°F or higher in July while conditioned air leaks out through every seam.
What this means for insulation work is simple: Oak Hills isn’t a code-minimum market. It’s a performance market. The fix that works in a coastal tract house won’t touch the heat gain here. We routinely find homes where the “insulation” has compressed to the R-value of a bath towel, and where ducts run through unconditioned space with zero thermal barrier. Retrofit work has to account for odd rafter spacing, manufactured home cavities, and roofs that have been baking under desert sun for decades. That’s why our approach starts with what’s actually up there, not a generic square-footage formula.
Our Main Oak Hills Services
Most Oak Hills homeowners call us about two things: attic insulation that’s failed or was never adequate, and spray foam for the air-sealing and thermal performance that this climate demands. Here’s what each one involves locally.
Attic Insulation in Oak Hills
Attic work in Oak Hills usually means either topping off existing loose fill or removing old, compacted material and starting fresh. The heat up there is the real issue. A poorly insulated attic turns into an oven that radiates heat into your living space all afternoon, forcing the AC to fight a losing battle. We inspect the existing R-value, check for gaps around vents and recessed lights, and recommend either blown-in cellulose or fiberglass batts depending on your framing and budget. See the full breakdown on our Attic Insulation in Oak Hills page.
Spray Foam Insulation in Oak Hills
Spray foam earns its keep in Oak Hills because it does two jobs at once: it insulates and it air-seals. In a high-desert climate with big day-night temperature swings, air infiltration is often a bigger comfort problem than the insulation itself. Open-cell foam works well for attic roof decks, while closed-cell adds structural strength and moisture resistance for crawlspaces and rim joists. We carry both Icynene and Demilec systems. Details are on our Spray Foam Insulation in Oak Hills page.

Blown In Insulation in Oak Hills
Blown in insulation is the most common retrofit we install in Oak Hills because it fills irregular cavities fast and delivers real R-value per dollar. Many homes here have attics with inconsistent framing, odd-shaped bays, and existing batts that are either missing sections or compressed flat. Blowing in cellulose or fiberglass solves that by covering everything evenly, including around ducts and wiring.

What Oak Hills 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."
— Nathan Padgett"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Gabriela Herrera"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
