Insulation Company in Running Springs, CA
Blown in insulation is the workhorse retrofit for Running Springs cabins, A-frames, and chalets built between the 1920s and 1970s. Most of these homes started as summer retreats with empty wall cavities or a thin layer of something that settled decades ago. At 6,000 feet, that means frozen pipes, rooms that never warm up, and heating bills that climb all winter. We’re Comfort Zone Insulation Co, an insulation-only specialist serving Running Springs since 2012, and we install blown in cellulose and fiberglass plus spray foam and attic systems from eight major brands. Call (855) 341-7856 for a free estimate.
Why Running Springs Homes Are Different
Running Springs sits at roughly 6,000 feet in the San Bernardino Mountains, where winter nights drop below freezing and summer afternoons swing 30 to 40 degrees from the morning low. Insulation here isn’t a comfort upgrade. It’s freeze protection, wildfire defense, and the difference between a cabin that holds heat and one that leaks it through every wall and roof plane.
The housing stock drives most of what we do. Small to mid-size mountain cabins, A-frames, and chalets from the 1920s through the 1970s dominate, and many were framed for weekend summer use with no insulation at all, single-pane windows, and shallow vented roof cavities. Knee walls and floors over exposed crawlspaces were never designed for year-round occupancy. We routinely open walls and find nothing but studs and siding. The seasonal cabin-to-year-round-home conversion is the defining Running Springs project.
Snow load and ice dams punish under-insulated roofs. Freeze-thaw cycles work on every exterior surface. Wildfire risk means Class A fire-rated materials and ember-resistant attic detailing aren’t optional extras. We think about all of it before we recommend a single product.
Our Main Running Springs Services
Running Springs homeowners call us most about two things: attics that leak heat all winter and walls that were never insulated to begin with. Here’s how each job works locally.
Attic Insulation in Running Springs
Most heat loss in a mountain cabin goes straight up through the roof, and Running Springs attics are trickier than most. Many older cabins have shallow, vented roof cavities that can’t take standard blown-in depths without baffles and air-sealing first. We inspect the existing venting, check for ice dam conditions, and choose a material that performs in sub-freezing temperatures while keeping embers out. The full breakdown of what this costs and how we handle attics specifically is on our Attic Insulation in Running Springs page.
Spray Foam Insulation in Running Springs
For A-frames with vaulted ceilings and cabins with exposed crawlspaces, spray foam often makes the most sense because it air-seals while it insulates. Running Springs homes have joints and gaps that fiber alone can’t close, especially where frozen pipes are a real risk. We install open- and closed-cell systems from Icynene and Demilec, choosing the right product for the cavity and the exposure. See Spray Foam Insulation in Running Springs for the full story on foam in mountain construction.

Blown In Insulation in Running Springs
Blown in insulation in Running Springs is usually the most practical way to upgrade walls and attics without tearing open finished surfaces. Most cabins here were built before anyone thought about R-value, and the dominant retrofit is dense-packing cellulose or fiberglass into empty cavities, then topping up the attic to a depth that actually handles a February night at 6,000 feet. We install blown in products from Owens Corning, Johns Manville, Knauf, and others, and we carry Blown In Insulation as a core service because it fits the housing stock better than anything else.
Cellulose Insulation
Signs you need it
Rooms that never hold temperature, walls that feel cold to the touch in winter, and attic floors with less than eight inches of settled material are the usual giveaways.
What it costs in Running Springs
Dense-packing exterior walls with cellulose typically runs $1,500 to $3,500 for an average Running Springs cabin, including prep and cleanup.
How we do it
We drill access holes, dense-pack the cavities to the correct pounds-per-cubic-foot density, and patch every hole before we leave.
Blown In Attic Insulation
Signs you need it
Ice dams forming at the roof edge, a furnace that runs constantly, or snow melting unevenly off your roof are the clearest indicators.
What it costs in Running Springs
Blown in attic insulation in Running Springs averages $1,400 to $3,200 depending on attic access, existing depth, and whether baffles and air-sealing are needed first.
How we do it
We air-seal bypasses, install baffles where venting is short, and blow to a consistent depth that meets the climate zone’s R-value target.
Blown In Cellulose Insulation
Signs you need it
Drafty rooms above unheated crawlspaces and old walls with no visible insulation are common in 1920s to 1970s Running Springs cabins.
What it costs in Running Springs
Blown in cellulose for a typical wall retrofit runs $1,800 to $4,000 when floors and knee walls are included.
How we do it
We access each bay from inside or out, fill to a dense-pack standard, and verify coverage with thermal imaging before closing up.
Blown In Fiberglass Insulation
Signs you need it
Attic insulation that has compacted, shifted, or been disturbed by rodents or roof work is a sign that a fresh blown-in fiberglass layer is due.
What it costs in Running Springs
Blown in fiberglass attic work averages $1,200 to $2,800 in Running Springs, with dense-pack wall work typically $1,600 to $3,800.
How we do it
We remove or top up existing material as conditions require, then blow at a consistent density and depth using calibrated equipment.
What Blown In Insulation Costs in Running Springs
| Item | Typical range in Running Springs |
|---|---|
| Blown in attic insulation (full attic) | $1,400 – $3,200 |
| Dense-pack exterior walls | $1,500 – $3,500 |
| Blown in cellulose wall retrofit with floors/knee walls | $1,800 – $4,000 |
Is blown in insulation worth it in a Running Springs cabin?
Yes, and the payback is faster here than in the flats because heating loads are higher and winter is long. Most homeowners notice the difference the first cold night after the job.
Can you blow insulation into walls without removing the siding?
Usually yes. We drill access holes from inside or outside, dense-pack the cavity, and patch cleanly. Interior access works well if you’re already repainting, and exterior access works better when interiors are finished.
