Insulation Company in Mentone, CA
Blown in insulation is the most common call we take in Mentone, and the reason is straightforward: most homes here were built between 1955 and 1980 with R-11 attic batts that have baked, flattened, and lost their loft under decades of high-desert sun. When attic temperatures push past 140°F, that thin layer stops doing its job and the heat soaks straight into the living space. We fix it with air sealing first, then blown-in loose-fill matched to your attic’s depth and your cooling load. Call (855) 382-3451 and we’ll tell you exactly what’s up there and what it needs.
Why Mentone Homes Are Different
Mentone sits at the foot of the San Bernardino Mountains in a hot, dry inland valley. Summer attic temperatures routinely pass 140°F by midday, which means the insulation conversation here is almost entirely about heat gain, not winter heat loss. Most of the housing stock is mid-century and 1960s-70s single-story ranch and tract homes on generous lots. The original attic insulation in these homes was R-11 fiberglass, which was the minimum code at the time, and it has typically compacted to half its rated depth. Exposed or thinly covered ductwork runs through those same attics, absorbing heat and raising supply-air temperatures before conditioned air ever reaches a register.
The day-night temperature swing at the base of the mountains adds another layer: the house bakes all afternoon, releases heat into the evening, then cools sharply overnight. Without adequate attic ventilation and insulation depth, your air conditioner fights a thermal load that never really ends. Dry air, at least, works in our favor. Fiberglass and blown-in cellulose both perform well here once air sealing is done, because mold and moisture issues are less aggressive than in coastal climates. The defining local problem is radiant heat and ventilation, which is why we fix those before adding a single new inch of insulation.
Our Main Mentone Services
Two services account for most of the calls we run in Mentone: attic insulation upgrades for the older ranch homes, and spray foam where sealing and R-value have to happen at the same time.
Attic Insulation in Mentone
Most Mentone attics need a complete do-over, not a top-off. The original batts are usually compacted, dusty, and shifted, and the attic floor often has more gaps than the homeowner realizes. We remove the old material, air seal penetrations, verify or add ventilation, then install new insulation to a depth that makes sense for a 92359 cooling load. For the full breakdown on how we approach attics in Mentone, see Attic Insulation in Mentone.
Spray Foam Insulation in Mentone
Spray foam earns its price in Mentone when an attic doubles as a storage space, when ductwork runs through an unconditioned zone, or when homeowners want air sealing and insulation in one pass. Closed-cell foam also adds significant structural rigidity, which matters on older ranch homes with original framing. We run open-cell and closed-cell systems depending on the application. Details on material selection and costs are here: Spray Foam Insulation in Mentone.

Blown In Insulation in Mentone
Blown in insulation is the right call for most Mentone attics because it fills every irregular cavity, covers the attic floor continuously, and can be installed at whatever depth your cooling load demands. In a 1960s ranch with original R-11 batts and baked-out ductwork, we typically remove the old material, air seal the attic floor, and blow in loose-fill to R-38 or R-44, which drops ceiling temperatures noticeably during the hottest months. You can see the full method details on our Blown In Insulation page, but here is how it applies to Mentone.
Cellulose Insulation
Signs you need it
Your attic insulation has settled to less than 6 inches in depth, or you can see the tops of the ceiling joists across the attic floor.
What it costs in Mentone
Cellulose blown-in for a typical Mentone attic runs $1,200 to $2,400 depending on square footage, existing material removal, and target R-value.
How we do it
We remove the old material, air seal penetrations and top plates, then blow in GreenFiber cellulose to a consistent, measured depth across the entire attic floor.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic feel 8 to 10 degrees warmer than the rest of the house on summer afternoons, and the air conditioner cycles almost continuously from 3 p.m. onward.
What it costs in Mentone
Complete blown-in attic insulation with removal and air sealing for a 1,200 to 1,800 square foot Mentone ranch home typically lands between $1,800 and $3,200.
How we do it
We pull the old batts, seal every penetration from below, check or add soffit and roof ventilation, and blow loose-fill to the R-value your home’s cooling load requires.

How long does blown in insulation take in Mentone?

Is blown in insulation enough for a Mentone summer?
Yes, if it is installed at the correct depth and the attic is air sealed and ventilated first. Adding material without sealing is the most common mistake we see in Mentone homes. We inspect ventilation before adding insulation.

In Mentone, price moves most with attic access: low-pitch roofs, tight scuttle holes, and cramped truss spacing all add labor time. Older ranch homes with vermiculite or rodent contamination in the attic also cost more because removal and sanitizing come first. You get an upfront, line-item price before any work starts, and that number does not change.

What Mentone Customers Say
"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."
— Maya Singh"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."
— Christine Park"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
