Insulation Company in Mentone, CA
Blown in insulation is the most common retrofit we handle in Mentone, and it’s usually the smartest first move for older foothill homes with under-insulated attics. Mentone’s position against the Crafton Hills means winter nights drop colder than most of the Redlands valley, and Santa Ana wind exposure along ridgeline lots pulls heat out of walls and attics faster than homeowners expect. If your attic has settled fiberglass or barely any coverage at all, call (866) 566-0304 and we’ll walk you through what it costs to fix properly.
Why Mentone Homes Are Different
Mentone doesn’t insulate like Redlands or Yucaipa. The town sits at the higher east end of the East Valley corridor, tucked against the San Bernardino National Forest foothills, and that elevation changes the job. Winter nights here run noticeably colder than the valley floor, so undersized attic insulation shows up as real heating loss from November through March. Summer afternoons still push radiant heat through the roof deck, but it’s the swing between the two extremes that defines the work, not flat-valley bake.
The housing stock leans heavily toward mid-century and earlier single-family detached homes: ranch-style layouts, cabin-influenced builds on larger lots, and a mix of newer foothill subdivisions. In the older homes we commonly find attics with a thin layer of settled fiberglass, irregular wall cavities, and knob-and-tube or early wiring that any insulation crew has to work around carefully. Along the Crafton Hills and forest-edge lots, dry Santa Ana winds and wildfire-season ember exposure add another layer: homeowners ask about ember-resistant attic venting and fire-rated exterior assemblies, so insulation jobs near the ridgeline often double as defensible-space conversations rather than simple R-value upgrades.
Our Main Mentone Services
Blown in is our primary service here, but two specialized jobs come up often enough in Mentone that we built dedicated pages for each: attic insulation diagnostics and full spray foam applications.
Attic Insulation in Mentone
Most Mentone heat loss starts at the top of the house. Older ranch homes and cabin-style builds frequently have attics with R-19 or less, and in a town with cold foothill nights that means the furnace runs longer than it should. We treat attic insulation as a focused diagnostic job: we check existing depth, identify air leaks around penetrations, and recommend the right material for your roofline, whether that’s blown-in fiberglass, cellulose, or batts. For the full breakdown on how we approach attic work in this specific market, see our Attic Insulation in Mentone page.
Spray Foam Insulation in Mentone
Spray foam earns its keep on Mentone’s ridgeline and forest-edge lots, where wind-driven air infiltration is the quiet killer. Closed-cell foam from Icynene or Demilec seals the building envelope, adds structural rigidity, and performs far better than fiberglass when Santa Ana gusts press against exterior walls. It’s also the right conversation for homes where wildfire ember exposure makes unsealed attic penetrations a liability. Read the full local breakdown on our Spray Foam Insulation in Mentone page.
Blown In Insulation in Mentone
Blown in insulation is our most-requested service in Mentone because it’s the fastest way to bring an older foothill home’s attic up to current efficiency standards without opening walls. Many of the ranch-style and cabin-era homes here still have whatever thin fiberglass layer was installed decades ago, and Mentone’s cold winter nights expose that deficiency quickly. Blown-in material levels out uneven coverage, fills irregular cavities, and gives you the R-value the local climate actually demands.

Cellulose Insulation
Signs you need it
Your attic insulation has settled to below the top of the ceiling joists, or your heating bills climb every winter while rooms directly under the attic stay cold.
What it costs in Mentone
Cellulose installation in Mentone typically runs $1.20 to $2.30 per square foot, depending on the depth needed and access conditions in the older ranch homes.
How we do it
We air-seal the attic floor penetrations first, then dense-pack or loose-fill with GreenFiber cellulose to the target depth, checking coverage with a calibrated gauge as we go.
Blown In Attic Insulation
Signs you need it
You can see the tops of the attic joists, or upstairs rooms are noticeably colder than the rest of the house from fall through spring.
What it costs in Mentone
Blown in attic insulation in Mentone typically falls between $1,500 and $4,000 for an average single-story home, with larger split-level or foothill lots running higher.
How we do it
We run a hose into the attic from outside, blow the material to an even, measured depth across the entire attic floor, and finish with a post-installation coverage check.
Blown In Fiberglass Insulation
Signs you need it
Your attic has a thin layer of old, compressed fiberglass that no longer provides meaningful resistance to Mentone’s winter cold or summer radiant heat.
What it costs in Mentone
Blown in fiberglass in Mentone runs $1.10 to $2.10 per square foot, with final cost driven by target R-value and how much old material needs removal first.
How we do it
We remove or level compromised material, prep the attic floor, and blow Owens Corning fiberglass to the specified depth with a temperature and moisture check before we finish.
Loose Fill Insulation
Signs you need it
Your attic has bare spots, uneven coverage, or an older home’s framing that leaves irregular cavities most batts simply can’t fill properly without gaps.
What it costs in Mentone
Loose fill insulation in Mentone typically runs $1,500 to $4,500 depending on square footage, depth, and whether we’re starting from a bare attic floor.
How we do it
We select the right loose fill material for your situation, prep and air-seal the space, then blow an even layer to the recommended depth and verify final R-value.

Can you blow insulation into an existing attic without removing the old material?
Yes, in most cases we can blow over existing insulation after checking for moisture and air-sealing penetrations. If old material is compressed, moldy, or pest-damaged, we’ll recommend removal first. Call (866) 566-0304 for a free assessment.

What Mentone Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
- Diego Castillo"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."
- Gilbert Herrera"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."
