Insulation Company in Mentone, CA
Blown in insulation is the most common fix we recommend for Mentone homes built before 1980, because the original attic batts in this valley have usually settled, crumbled, or blown clear out of the soffit vents after decades of 140°F attic heat. We match the right material – cellulose, fiberglass, or spray foam – to your home’s build, not to what’s easiest for us to install. Cozy Insulation Co has served Mentone since 2011 with an eight-brand material portfolio, so you get options, not a one-size pitch. Call (855) 382-3925 for a free attic assessment.
Why Mentone Homes Are Different
Mentone sits at the base of the San Bernardino Mountains in a hot, dry inland valley where summer attic temperatures routinely exceed 140°F. That changes everything about how we approach insulation here. In coastal cities or mountain communities up Highway 38, the conversation starts with R-value for cold weather. In Mentone, the first thing we look at is radiant heat: is your attic holding heat against your ceiling, and can it shed that heat fast enough at night?
Most Mentone homes are single-story ranch or custom builds on larger rural lots, many from the 1950s and 1960s. Those original attics typically got R-11 batts or a thin layer of blown-in material that has since settled to a fraction of its original depth. We routinely find original batts that have crumbled and blown out of the vents from decades of baking. Newer infill construction has its own issues: code-minimum insulation that meets the letter of the law but leaves rooms hot in July and cold on frosty January nights at 1,700 feet. Many properties also have detached garages, shops, or covered patios that factor into whole-property insulation decisions.
The takeaway for Mentone: insulation here isn’t just about adding R-value. It’s about radiant barriers, ventilation, and choosing materials that hold their shape through 60-degree day-night temperature swings.
Our Main Mentone Services
Two services account for most of the calls we get from Mentone homeowners: attic insulation and spray foam insulation. Here’s what each one involves in this specific climate.
Attic Insulation in Mentone
Attic insulation in Mentone usually means removing or topping off what’s already up there. In older ranch homes, we’re often pulling out crumbled fiberglass that’s been cooking since the Eisenhower administration and replacing it with fresh batts or blown-in material at the correct depth. In newer homes, we’re adding to code-minimum coverage and checking that soffit and ridge vents are actually moving air. The goal is an attic that stops radiating heat into your living space by mid-afternoon. For the full breakdown of this service, see our Attic Insulation in Mentone page.

Spray Foam Insulation in Mentone
Spray foam insulation in Mentone solves the air-sealing problem that batts alone can’t fix. Closed-cell foam from Icynene or Demilec seals gaps around can lights, plumbing penetrations, and the attic hatch while adding significant R-value per inch. In a hot valley climate, that air seal matters as much as the insulation: it stops superheated attic air from siphoning into the house through gaps you can’t see from below. Open-cell foam works well for sound control in interior walls near Highway 38 or the railroad corridor. Details and pricing are on our Spray Foam Insulation in Mentone page.

Blown In Insulation in Mentone

Blown in insulation is our most-requested service in Mentone, and for good reason: it’s the fastest way to restore attic R-value in older ranch homes where original batts have baked, settled, or blown out of the soffit vents. In this climate, blown-in material also fills the irregular gaps and odd cavities common in custom mid-century builds, something rigid batts can’t do. We install both fiberglass and cellulose blown-in systems, and for the full range of what this service covers, see our Blown In Insulation hub page.
Cellulose Insulation
Signs you need it
Your attic has settled blown-in material that’s compacted to less than six inches deep, or you see dust and fibers escaping from ceiling fixtures and gaps around trim.
What it costs in Mentone
Blown-in cellulose in Mentone attics typically runs $1.00 to $2.50 per square foot installed, depending on depth and whether old material must be removed first.
How we do it
We seal bypass gaps, mark target depth, and blow GreenFiber cellulose to an even layer at the R-value your attic needs, then fluff and level it for consistent coverage.
Blown In Attic Insulation
Signs you need it
Rooms below the attic run hot by late afternoon in summer, your AC runs constantly from May through October, and your attic floor has bare or thin spots visible between old batts.
What it costs in Mentone
Blown-in attic insulation in Mentone typically costs $1,500 to $4,500 for a standard ranch home, with larger custom builds and detached shops falling at or above that range.
How we do it
We remove or top off the existing layer, install baffles to protect soffit ventilation, blow material to code depth, and set up ventilation so the attic can shed summer heat.
Blown In Fiberglass Insulation
Signs you need it
Your attic has old fiberglass batts that have crumbled or shifted, leaving bare ceiling joists and hot spots in rooms below.
What it costs in Mentone
Blown-in fiberglass in Mentone attics typically runs $0.80 to $2.00 per square foot installed, with removal of old material adding to the total.
How we do it
We prep the attic, seal air leaks, and blow an even layer of fiberglass to the target R-value, then level high spots so depth is consistent across the whole floor.
Loose Fill Insulation
Signs you need it
You have shallow or uneven coverage in your attic, or you’re insulating an irregular space like a converted garage, shop, or addition where batts won’t fit cleanly.
What it costs in Mentone
Loose fill insulation in Mentone, whether cellulose or fiberglass, falls in the $0.80 to $2.50 per square foot range depending on material and final depth.
How we do it
We assess the space, set containment, and blow loose fill to an even, measured depth, then verify coverage at the corners and edges where heat leaks most.

What Mentone Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Jason Hoffman"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Colleen Vaughn"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Amanda Sullivan
