Insulation Company in Running Springs, CA
Blown in insulation is the most common request we get from Running Springs homeowners, and the reason is simple: most of the cabins and older houses up here were built before insulation was taken seriously at altitude. At 6,000 feet, a home with thin 2×4 walls and original 1960s batts leaks heat all winter long, and the furnace runs nonstop just to keep a room at 58 degrees. We install blown in insulation, attic insulation, and spray foam across the 92382 zip code, matching the material to the house rather than pushing one product on every job.

Why Running Springs Homes Are Different
Running Springs sits at roughly 6,000 feet in the San Bernardino Mountains, right off Highway 18 between Crestline and Big Bear. Winter nights drop into the 20s and below on a regular basis, snow sits on roofs for weeks, and freeze-thaw cycles work at siding, framing, and anything exposed to the air. Most of the housing stock dates from the 1950s through the 1970s: wood-sided cabins and vacation homes with 2×4 walls, raised floors, and crawlspaces that were never sealed against mountain cold. Many were built as weekend getaways and later converted to full-time homes, without anyone upgrading the thermal envelope.
The biggest heat loss point in a Running Springs house is almost always the floor system. Crawlspaces open to cold air, rim joists with gaps, and original batts that have slumped away from the framing or been torn apart by rodents mean warm air escapes downward all winter. We routinely find 1960s-era fiberglass that looks fine from the access hatch but has collapsed to half its original thickness. The insulation challenge here is not a mild coastal cooling problem; it is a heating-dominated climate with snow load, ice, and real freeze protection requirements. A home insulated to lowland Southern California standards will be cold, drafty, and expensive to heat in Running Springs.
Our Main Running Springs Services
Most Running Springs homeowners call us about two things: getting the attic insulated properly, or upgrading to spray foam for air sealing and moisture control in a mountain house. Here is what each involves up here.
Attic Insulation in Running Springs
Attics in Running Springs are typically shallow, vented, and crammed with decades of debris: old wiring, rodent trails, and batts that have been pushed around by decades of snow load on the roof deck. Heat rises, and in a mountain house it rises straight through the ceiling into a cold attic, then through the roof. Upgrading attic insulation here means air sealing first, then adding material to a depth that actually holds heat in winter. Snow on the roof is a factor too: a poorly insulated attic melts snow unevenly, which leads to ice dams along the eaves. Attic Insulation in Running Springs covers the full scope of what we do up here, from air sealing to blown in cellulose or fiberglass.
Spray Foam Insulation in Running Springs
Spray foam solves two problems at once in a mountain cabin: it insulates and it air seals. That matters in Running Springs because cold air finds its way through every crack in a 50-year-old wood-framed structure, and fiberglass alone will not stop it. We install closed-cell and open-cell foam through Icynene and Demilec, two brands most general insulation contractors do not carry. Closed-cell foam works especially well in crawlspaces and rim joist areas that are open to cold air, while open-cell foam is a strong fit for attic rooflines and walls. Spray Foam Insulation in Running Springs has the full details on material choices, thickness, and what jobs look like in mountain homes.

Blown In Insulation in Running Springs
Blown in insulation in Running Springs is the fastest way to bring an older mountain home up to something close to modern thermal standards. Most of these houses were built with 2×4 walls and little or no insulation, or with batts that have slumped, settled, and been shredded by rodents over 50 or 60 winters. Blown in cellulose or fiberglass fills wall cavities, floor cavities, and attic spaces completely, getting into the gaps and odd framing that batts can never reach. It is a practical fix for houses that were never insulated to mountain standards and now run the furnace around the clock from November through March. Our full Blown In Insulation service page covers the methods and materials in detail.
Cellulose Insulation
Signs you need it
Rooms over the crawlspace or garage feel cold in winter even with the heat on, and your furnace runs constantly without warming the house above 60 degrees.
What it costs in Running Springs
Dense-packed cellulose in a crawlspace or wall cavity in Running Springs typically runs $1.90 to $3.10 per square foot installed, depending on access and depth.
How we do it
We drill access points in the wall or floor framing, blow cellulose to a target density under pressure, then patch and clean every access point before we leave.
Blown In Attic Insulation
Signs you need it
Snow melts unevenly off your roof, you can see the attic floor boards through thin or settling insulation, or upstairs rooms are always colder than the rest of the house.
What it costs in Running Springs
Blown in attic insulation in Running Springs generally costs $1.10 to $1.90 per square foot for full coverage, with the final price depending on existing material, attic depth, and air sealing needs.
How we do it
We air seal penetrations first, then blow cellulose or fiberglass to the specified R-value across the attic floor, keeping baffles clear so the roof deck still vents properly.
What Blown In Insulation Costs in Running Springs
| Item | Typical range in Running Springs |
|---|---|
| Blown in attic insulation (full coverage) | $1.10 – $1.90 per sq ft |
| Dense-packed wall or floor cellulose | $1.90 – $3.10 per sq ft |
| Blown in fiberglass attic insulation | $1.35 – $1.85 per sq ft |
Is blown in insulation worth it in a Running Springs cabin?
Yes, because most cabins up here were built with thin walls and minimal insulation, and blown in material fills the actual cavities instead of leaving gaps like failing batts do. Heat loss in winter drops immediately, and the furnace stops cycling every few minutes. Call us for a specific assessment of your house.
Can you blow insulation into existing walls without tearing them apart?
Yes, we drill small access holes through siding or drywall, blow the material in under pressure, then patch the holes so they disappear. The job usually takes one day. Call (833) 390-3099 to schedule an inspection.

FAQs About Insulation Company in Running Springs
Most Running Springs jobs are scheduled within one to two weeks, and we do our best to work around mountain weather so material does not sit in snow. Call (833) 390-3099 and we will give you a real date on the first call, not a vague window.
For most insulation retrofits, no, but every job is different and we know the local permitting path when one is needed. We handle the paperwork side so you do not have to. We will tell you upfront if your project triggers anything beyond standard work.
We handle both. If old batts have been destroyed by rodents or water, we remove and bag them before installing new material. If the existing insulation is just thin, we often add on top of it to hit the target R-value without the extra removal cost.

What Running Springs Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— David Tran"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."
— Justin Chen"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."
