Insulation Company in Mentone, CA
Blown in insulation is the most common fix we install in Mentone homes, and for good reason. Most houses here were built between the 1950s and 1980s, when attic insulation was an afterthought: a thin layer of batts that has since settled, compressed, or blown around in the wind. Add Mentone’s brutal summer attic heat, where temperatures above 140°F bake the space under sun-exposed roofs, and you get cooling bills that climb every July. Our job is simple: get the right R-value into the attic so the heat stays out and the air conditioning stays in. Call (844) 241-0737 and we’ll tell you exactly what your attic needs.
Why Mentone Homes Are Different
Mentone sits in a strange thermal pocket. The San Gorgonio Pass funnels hot, dry wind down through the foothills, so summer afternoons hit harder here than in Redlands a few miles west. But at 2,300 feet of elevation, winter nights drop below freezing more often than people expect. The insulation has to work both directions: reflecting and resisting summer attic heat, while holding warmth inside during cold snaps. Older ranch-style homes and single-story mid-century builds across ZIP 92359 were never designed for this. We regularly find R-11 or worse in attics that should carry R-38 to R-49 for this climate zone. And because many Mentone lots are larger with detached garages and standalone workshops, there’s often a secondary unconditioned space leaking heat into the property’s total energy picture. Mobile and manufactured homes add another layer: their ceiling cavities are shallower, so material choice matters more. You can’t just blow in more fiberglass and call it done. You need the right product density and sometimes a radiant barrier approach to cut the solar gain that cooks these structures from above.
Our Main Mentone Services
Most Mentone homeowners call us about one of two things: an attic that’s bleeding cooled air in summer, or a room addition, garage conversion, or new build that needs a proper thermal seal from the start. Both start with the same question: which material actually fits this house?
Attic Insulation in Mentone
Attic work in Mentone usually means removing old, settled material, air sealing the top plates and penetrations, and then installing the right insulation for the roof’s exposure. South-facing and west-facing roof sections over the same floor plan can differ by 30°F in summer. We see that every week. If your attic insulation is original to a home built before 1990, you’re overpaying every summer. Read the full breakdown on our Attic Insulation in Mentone page.

Spray Foam Insulation in Mentone
Spray foam makes sense in specific Mentone situations: unvented attics, cathedral ceilings, tight cavities in manufactured homes, and outbuildings or detached garages you’re converting into living or workspace. Closed-cell foam’s air-sealing properties matter in a place where dust-laden wind moves through the pass. When the roof deck gets direct sun all afternoon, an unvented foam assembly can keep the attic inside the thermal envelope. See where foam fits on the Spray Foam Insulation in Mentone page.

Blown In Insulation in Mentone
Blown in insulation is the workhorse solution for Mentone attics, and most of the homes we visit need exactly that: loose-fill material blown into the attic floor to rebuild lost R-value and seal the gaps that old batts never covered. The typical house in this foothill town has a shallow attic cavity, a sun-baked roof, and decades of settled insulation that’s barely doing its job. We blow in fresh material to a consistent depth, covering joists, top plates, and the odd corners that batts always miss. It’s the fastest way to fix a Mentone cooling bill, and it’s usually done in a single morning. For a deeper look at how this method works across different homes, see our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation looks thin, dusty, or uneven across the floor, and you can see the ceiling joists in most areas.
What it costs in Mentone
Cellulose blown-in for a typical Mentone attic runs $1.50 to $2.80 per square foot, depending on depth and existing material removal.
How we do it
We remove any compromised material if needed, air-seal the major penetrations, then blow cellulose to a consistent, code-plus depth with a machine calibrated for the target R-value.
Blown In Attic Insulation
Signs you need it
Upstairs rooms run 5 to 10 degrees warmer than the rest of the house all summer, and the air conditioner cycles constantly from mid-morning on.
What it costs in Mentone
Full blown-in attic insulation for a 1,200 to 1,800 square foot Mentone home usually lands between $1,800 and $4,500 including removal of failed material.
How we do it
We map the attic, remove or treat old material that’s compromised, seal the bypasses, and blow the insulation to a uniform depth that meets climate-zone spec for ZIP 92359.
Blown In Fiberglass Insulation
Signs you need it
Your attic has older fiberglass that’s compressed, mouse-tunneled, or blown into sparse piles, leaving bare patches along the eaves.
What it costs in Mentone
Blown-in fiberglass typically runs $1.20 to $2.30 per square foot installed, with most Mentone attics landing in the $1,700 to $3,900 total range.
How we do it
We install loose-fill fiberglass with pneumatic equipment, making multiple passes for even coverage and checking depth markers throughout the attic before we finish.
What Blown In Insulation Costs in Mentone
| Item | Typical range in Mentone |
|---|---|
| Blown-in fiberglass (installed, per sq ft) | $1.20 – $2.30 |
| Cellulose blown-in (installed, per sq ft) | $1.50 – $2.80 |
| Full attic blow-in, 1,200 – 1,800 sq ft home | $1,800 – $4,500 |
Does blown in insulation really bring down cooling bills in Mentone?
Yes. An under-insulated attic in Mentone can reach 150°F in July, radiating heat into the living space for hours after sunset. Rebuilding attic R-value typically cuts cooling load noticeably within the first month, especially in older ranch homes with original thin batts.
Is blown in insulation worth it in a manufactured home in Mentone?
Usually, yes. Manufactured homes have shallow ceiling cavities, so every inch of insulation counts more. The roof surface absorbs direct sun all day, and thin or settled material turns the interior into an oven. We size the job to the cavity depth and pick the material that performs within that constraint rather than forcing more than the space allows.
Brands We Service in Mentone
We stock and install across a broad manufacturer base, which means you get the material that actually suits your Mentone home rather than whatever one brand happens to make. That includes Rockwool mineral wool for fire resistance and sound control, CertainTeed fiberglass for standard attic rebuilds, and Icynene and Demilec spray foam for air-sealing and closed-cell performance. See the full list on our brands page.

In Mentone, two things push price up more than anything: access difficulty in shallow, low-slope attics, and the need to remove old material that’s become a rodent or dust problem before new insulation goes in. We quote one number before we start, and that’s the number on the invoice, no surprise line items for “unexpected conditions.”
Neighborhoods We Serve in Mentone
We work throughout ZIP 92359 and the immediate foothill streets around it. Mentone’s housing is spread out, so the issues shift street by street: an older ranch near the highway sees different heat load than a manufactured home tucked against a hillside. We know both by name.
- Mentone Beach area and streets off Crafton Avenue
- Lots along Highway 38 toward the mountain grade
- Older ranch tracts near Mentone Boulevard and Garnet Street
- Manufactured home communities and large lots east of the pass
- Homes along the Crafton Hills edge and Sunset Drive corridor
Most Mentone jobs are scheduled within the same week, and we can often be on-site within a day or two when a project is urgent or a home sale inspection flagged the attic.

FAQs About Insulation Company in Mentone
Most estimates in Mentone happen within two to four business days, and we can often tighten that when a buyer’s inspection or an unexpected cold snap makes the timeline urgent. Call (844) 241-0737 and we’ll give you the earliest real date rather than a range we can’t hold.
Not entirely different, but the foothill elevation and San Gorgonio Pass wind exposure do change the calculation. Mentone’s colder winter nights and hotter summer attic peaks mean we lean toward higher effective R-values and, in many cases, air sealing plus radiant barrier over the roof deck to handle solar gain.
We handle everything that’s needed on the installation side, including the paperwork required by San Bernardino County for insulation retrofits and any applicable utility rebate documentation our materials qualify for. You’ll get a clean record of what was installed, to what depth and R-value, and what the material covers.
If your Mentone home is fighting the summer with thin attic insulation, or you’ve got a room that never holds temperature, let’s fix the actual problem. Call (844) 241-0737 for a free estimate, and we’ll tell you exactly what’s wrong in the attic, what it’ll take to make it right, and what it costs before anyone picks up a hose.

What Mentone Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Gilbert Hernandez"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Paige Ziegler"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."
