Insulation Company in Mentone, CA
Blown in insulation is the most common fix we install in Mentone attics, where mid-century homes and manufactured houses on larger lots routinely bake under the Inland Empire sun. Older construction here often has settled fiberglass or nothing more than a few inches of loose fill, and the result is the same: bedrooms that never cool down, AC units that run all afternoon, and utility bills that climb every July. Placentia Insulation has served Mentone since 2018, matching the right material – cellulose, fiberglass, or spray foam – to each home’s construction. Call (855) 773-6429 for a free estimate.
Why Mentone Homes Are Different
Mentone sits at the base of the Crafton Hills, east of Redlands, in a hot, semi-arid pocket of the Inland Empire where summer attic temperatures routinely push well past 130°F. That changes what insulation has to do here. This is not a cold-climate heating problem; it’s a heat-defense and attic-ventilation problem. Homes on large, unshaded lots with dark shingle or composition roofs absorb direct sun for ten or twelve hours a day in July and August, and that heat radiates down through the ceiling long after sunset.
The housing stock adds another layer. Mentone mixes mid-century single-family homes with manufactured and mobile homes, many of which were built before modern insulation codes and still carry whatever the original builder put in – often a thin layer of R-11 or R-19 fiberglass that has settled to half its rated value. Newer custom builds on the larger lots fare better, but even those benefit from air sealing and dense-pack cellulose in the walls. On sunny south- and west-facing roof lines, we routinely find degraded batts, gaps at the eaves, and venting that cannot keep up with the heat load. That combination – intense sun, older construction, and under-vented attics – means a standard insulation quote from another area of the Inland Empire will not fit a Mentone attic. The work here is about cutting solar heat gain and pairing insulation with the right ventilation strategy.
Our Main Mentone Services
Most Mentone homeowners call us about one of two things: an attic that turns the second floor into an oven, or a home that needs air sealing and thermal control from the roof deck down. Here’s how each one works in this area.
Attic Insulation in Mentone
Mentone’s hot roof decks demand more than a fresh layer of fiberglass. We assess the existing material, measure settled depth, and address ventilation alongside insulation – because an R-38 batt under a 140°F roof deck without soffit-to-ridge airflow still transfers heat downward. Older mid-century homes and manufactured houses often have undersized gable vents or none at all, and that is where the real fix begins. For homes with existing insulation that has compacted, we remove or top it and install the right R-value for the roof profile. See the full breakdown on our Attic Insulation in Mentone page.
Spray Foam Insulation in Mentone
For Mentone homes with unvented attics, knee walls, or metal-roofed manufactured units, spray foam changes the equation. Closed-cell foam from Demilec or Icynene creates an air and thermal barrier in one pass, which matters when attic temperatures swing from 45°F at night to 135°F by afternoon. We use open-cell where air sealing matters and budget is a factor, and closed-cell where the roof deck itself needs a vapor and thermal break. Cathedraized ceilings in newer custom builds respond especially well. Learn what each option does on our Spray Foam Insulation in Mentone page.

Blown In Insulation in Mentone
Blown in insulation is the workhorse fix for Mentone’s older homes and mobile units, where attic hatches are small, joist spacing is irregular, and the existing material has settled into a thin, ineffective layer. Loose fill reaches the corners and odd cavities that batts miss, and in a climate where the attic is the enemy for five months of the year, that coverage is what keeps ceiling temperatures from turning bedrooms into heat sinks. We install both cellulose and fiberglass loose fill depending on the attic’s condition and the homeowner’s priorities, and every job starts with an airflow and moisture check. For a full picture of what this service involves, see our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your Mentone attic has old, settled fiberglass or bare spots between joists, and rooms below the ceiling stay warm well after sundown.
What it costs in Mentone
For Mentone attics, blown-in cellulose typically runs $1.50 to $3.00 per square foot installed.
How we do it
We air-seal bypasses around wiring and plumbing, blow GreenFiber cellulose to the target depth with a high-output hose, and confirm even coverage with depth markers.
Blown In Attic Insulation
Signs you need it
Your ceiling feels warm to the touch on summer afternoons, or you can see joist tops poking through the existing attic insulation.
What it costs in Mentone
Blown-in attic insulation in Mentone typically lands between $1,500 and $2,500 for a full attic… depending on the target R-value and whether we remove the old material first.
How we do it
We rake or vacuum the settled material, seal the attic floor penetrations, then blow loose fill to a consistent R-38 or higher across the entire attic floor.
What Blown In Insulation Costs in Mentone
| Item | Typical range in Mentone |
|---|---|
| Blown-in attic insulation (full attic) | $1,500 – $2,500 |
| Blown-in cellulose per square foot | $1.50 – $3.00 |
| Attic air sealing + loose fill package | $1.50 – $3.00 per square foot |
How long does blown in insulation last in a Mentone attic?
Cellulose in a dry, vented Mentone attic holds its R-value for 20 to 30 years. The bigger issue here is settlement – if the attic gets too hot or the fill was never dense-packed, it can compact and lose up to 20% of its depth within a decade. Call (855) 773-6429 and we’ll measure your current depth.
Can you blow insulation over what’s already in my Mentone attic?
Usually yes, as long as the existing material is dry and free of rodent damage or mold. We remove anything that’s compressed or contaminated first, then top the rest with fresh loose fill to the full target depth. Estimates are free.
Brands We Service in Mentone
We stock loose fill and batting from CertainTeed, spray foam from Icynene and Demilec, and cellulose from GreenFiber. That means the material for a Mentone attic usually comes off our truck same-day rather than waiting on a distributor. See what’s in active inventory on our brands page.

Most insulation-only jobs in Mentone do not require a permit, since adding loose fill, batts, or spray foam to an existing home is considered a routine upgrade under San Bernardino County’s residential rules. We handle any documentation or HOA checks that apply to your property before we start.
Yes. Mobile and manufactured homes make up a meaningful share of Mentone’s housing, and their attics and floor systems need a different approach than site-built homes. We inspect the roof profile, duct placement, and existing insulation before recommending blown-in cellulose or an open-cell foam strategy that does not overburden the roof structure.

What Mentone Customers Say
"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."
— Veronica Guzman"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."
— Rachel Sullivan"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
