Insulation Company in Mentone, CA
Blown in insulation is the most common retrofit we perform in Mentone, and for good reason: many homes here were built as mountain-adjacent retreats with thin or settled attic insulation that no longer controls the intense summer heat radiating through the roof. At Hollywood Insulation Co, we’re a dedicated insulation specialist serving Mentone since 2018, and we carry eight manufacturer brands so the material we recommend actually matches your home, not whatever happens to be on the truck. Call (866) 605-6949 for a free estimate on attic, spray foam, or blown-in work anywhere in the 92359 ZIP.
Why Mentone Homes Are Different
Mentone sits at the foot of the San Bernardino Mountains, and the climate here is the defining factor in almost every insulation job we take on. Summers routinely push past 100°F with punishing solar load on roofs, while winters stay mild with only the occasional cold snap. That means the real insulation challenge in Mentone is not keeping heat in, but keeping attic heat and radiant gain out.
The housing stock compounds the problem. Many Mentone homes are mid-century ranch-style builds, older cabins, or cottage-type residences. A significant number started as inexpensive retreats and were upgraded piecemeal over the decades. What we consistently find in Mentone attics is original insulation that has settled, compressed, or gone missing entirely in spots, often with low-pitch or flat roofs that leave very little room to work. Venting is frequently blocked by added storage or later remodeling, which traps heat and drives attic temperatures even higher. These are exactly the conditions that make method-matching critical: the right insulation for a 1960s ranch with a low-pitch roof is often completely different from what a newer build on the same street needs.
Our Main Mentone Services
Mentone homeowners call us most about two things: upgrading under-insulated attics and air-sealing with spray foam, both tied directly to how hot these homes get. Here’s what each one looks like in this part of the Inland Empire.
Attic Insulation in Mentone
Most Mentone attics we enter have fiberglass batts that were marginal when they were installed and have since settled or been disturbed by wiring, plumbing, and storage. We inspect the full ceiling plane, identify compressed or missing sections, and recommend either new batt installation or a blown-in retrofit depending on the roof pitch and access. Low-pitch roofs in particular make batt placement difficult, which is where our three installation methods under one roof really matter. See our full Attic Insulation in Mentone page for specifics on this service.
Spray Foam Insulation in Mentone
Spray foam addresses the air leakage that makes Mentone’s heat problem worse than the R-value alone suggests. Open-cell Icynene and Demilec systems air-seal the attic floor and roofline, cutting the stack effect that pulls superheated attic air into living spaces. Closed-cell options add structural rigidity, which matters on some of the older cottage-type buildings. For homes with blocked or inadequate venting, spray foam often solves the problem where batt or blown-in alone cannot. Details are on our Spray Foam Insulation in Mentone page.

Blown In Insulation in Mentone
Blown in insulation is the most practical retrofit for the majority of Mentone homes, because the existing insulation has usually settled, compressed, or thinned out over decades of hot summers. Loose fill can be installed over existing batts, into tight low-pitch attics where batts are nearly impossible to place properly, and into odd-shaped cavities common in older cabins and cottage-style houses. We install both GreenFiber cellulose and blown fiberglass, and the choice between them depends on your attic’s venting, access, and existing material. If you want to understand the full method, see Blown In Insulation on our main services page.
Cellulose Insulation
Signs you need it
Your attic insulation has settled to below the top of the ceiling joists, or you can see bare drywall from the attic hatch.
What it costs in Mentone
Blown-in cellulose in Mentone attics typically runs $1.50 to $3.50 per square foot installed, depending on the depth required and existing conditions.
How we do it
We run a hose from the truck to the attic, dense-pack or loose-fill GreenFiber cellulose to the specified depth, and verify coverage with depth markers across the entire ceiling plane.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic are 8 to 12 degrees hotter than the rest of the house during summer afternoons.
What it costs in Mentone
A full blown-in attic insulation job in Mentone generally lands between $1.50 and $3.50 per square foot, with smaller attics on the higher end of that range due to setup costs.
How we do it
We inspect the attic for venting and air leaks, then blow loose fill evenly across the attic floor to the R-value your home needs for this climate.
Blown In Cellulose Insulation
Signs you need it
Your energy bills spike every summer and the upstairs or back rooms never seem to cool down no matter how long the AC runs.
What it costs in Mentone
For a typical Mentone ranch or cabin attic, blown-in cellulose runs $1.50 to $3.50 per square foot installed, including prep and cleanup.
How we do it
We clear or work around existing obstructions, seal any major bypasses we can access, and blow GreenFiber recycled cellulose to an even depth matched to the target R-value.
Loose Fill Insulation
Signs you need it
Your attic has inconsistent insulation depth, bare patches, or areas where old batts have been pulled up for wiring or plumbing work and never put back.
What it costs in Mentone
Loose fill insulation in Mentone homes costs $1.50 to $3.50 per square foot, with the final number depending on whether we are topping up existing insulation or starting fresh.
How we do it
We determine the required depth for this climate zone, set depth markers, and blow loose fill in a uniform layer, including into the tight corners and low-clearance areas other methods cannot reach.
What Blown In Insulation Costs in Mentone
| Item | Typical range in Mentone |
|---|---|
| Blown-in cellulose (attic, full job) | $1.50 – $3.50 per sq ft |
| Blown-in fiberglass (attic, full job) | $1.50 – $3.50 per sq ft |
| Top-up over existing insulation | $1.50 – $2.50 per sq ft |
How long does blown in insulation last in Mentone heat?
Cellulose and fiberglass loose fill both last decades, but Mentone’s extreme attic heat can accelerate settling, especially if the material was installed at a marginal depth. Most Mentone attics benefit from a depth check every 10 to 15 years. Call (866) 605-6949 for a free attic assessment.
Can you blow insulation into a low-pitch Mentone attic?
Yes, and this is exactly where blown-in outshines batts, since the hose reaches areas a person cannot crawl into. We regularly retrofit low-pitch and flat-roof Mentone attics this way. Call (866) 605-6949 to schedule a look at your attic.

Most residential insulation retrofits in Mentone do not require a permit, since the work is contained within the existing building envelope. If your project involves structural changes or is part of a larger remodel, the permitting falls under that project’s scope. We will tell you during the estimate if we see anything that might trigger a permit requirement.
Yes, and those are some of the homes we know best. Older Mentone cabins often have minimal or no attic access, tight clearances, and insulation that has been pieced together over many years. We match the method to what the structure can actually accommodate, and we will tell you honestly if a particular approach will not work well in your space.

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."
— Miguel Garcia"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Heather Walsh"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."
— Cole Sullivan
