Insulation Company in Running Springs, CA
Blown in insulation is the most common retrofit we install in Running Springs, because most of the cabins and second homes up here were built between the 1950s and 1980s with attics that were either never insulated or only got a thin layer of fiberglass decades ago. At roughly 5,800 to 6,000 feet, Running Springs winters don’t just get cold – they cycle through hard freezes, heavy snow, and wind that finds every gap in a building envelope. Brea Insulation has served Running Springs since 2014, and the difference between a lowland insulation job and one up here comes down to R-value targets, air sealing, and knowing what snow load and ice damming do to a vaulted ceiling. Call us at (866) 858-4033 when you’re ready to stop heating the forest.
Why Running Springs Homes Are Different
Running Springs sits in the San Bernardino Mountains at an elevation where winter overnight lows routinely drop into the teens and snowpack lingers for weeks, not days. That changes the insulation math entirely. A house in Highland or Mentone can skate by with R-30 in the attic because the goal is keeping heat out. A Running Springs home needs R-49 or better in many cases, and the goal is keeping heat in while managing the freeze-thaw cycle that turns roof snow into ice dams. When warm air leaks through an under-insulated ceiling, it melts the snow on the roof, the meltwater runs down to the cold eaves, and it refreezes. That’s how you get ice dams prying shingles loose and water backing up under the roof deck.
The housing stock makes it more complicated. Much of Running Springs is mid-century and 1960s-80s mountain cabins and second homes, many with vaulted open-beam ceilings, single-pane windows, and wall cavities that were never insulated to any modern standard. A vaulted open-beam ceiling doesn’t leave an attic cavity to fill, so blown in insulation alone won’t solve the problem – it often needs to be paired with rigid board or spray foam to stop heat loss without tearing the ceiling apart. And because snow season limits attic access and roof work windows, the practical window for attic retrofits in Running Springs is often June through October. We plan around that.
Our Main Running Springs Services
Most Running Springs homeowners call us about two things: getting their attics up to mountain-grade R-values and sealing the air leaks that cause ice dams and frozen plumbing. Here’s what each involves up here.
Attic Insulation in Running Springs
Attic insulation in Running Springs usually means removing whatever thin, compressed fiberglass is up there and bringing the assembly up to a level that actually handles a 6,000-foot winter. We work in attics with limited access, snow-load concerns, and occasionally evidence of past ice damming along the eaves. The job often includes air sealing around ceiling penetrations before insulation goes in, because no amount of R-value fixes a hole. Attic Insulation in Running Springs covers exactly what we do up there, including how we handle vaulted ceilings and can lights.
Spray Foam Insulation in Running Springs
Spray foam earns its keep in Running Springs on vaulted open-beam ceilings and crawl spaces where batt or blown in material can’t form a proper air barrier. Closed-cell foam adds structural strength and stops air movement in one pass, which matters when wind exposure at elevation is pushing cold air through every seam. We install both open-cell and closed-cell lines, including Icynene and Demilec. Spray Foam Insulation in Running Springs explains where foam makes sense up here and where it doesn’t.

Blown In Insulation in Running Springs
Blown in insulation is the workhorse retrofit for Running Springs attics because it fills irregular cavities, gets around framing, and reaches spots no batt ever will. In a 1960s mountain cabin with odd joist spacing and a low-slope roof, blowing in cellulose or fiberglass is often the only practical way to get from R-11 to R-49 without a full remodel. We carry eight brands so we can match the material to the job – not the other way around – and our blown in work includes GreenFiber recycled cellulose for homeowners who want an eco-conscious option. Blown In Insulation is one of our three core services for a reason: it’s fast, it’s effective, and it’s the right solution for most older Running Springs attics.
Cellulose Insulation
Signs you need it
Your attic has thin or patchy fiberglass, your heating bills spike every winter, or you can see the tops of ceiling joists exposed because the old insulation has settled below them.
What it costs in Running Springs
Cellulose blown in insulation in Running Springs typically runs $1.10 to $1.80 per square foot installed, depending on the target R-value and how much prep the attic needs.
How we do it
We air seal the ceiling plane, install baffles at the eaves to protect ventilation, then blow GreenFiber or another cellulose product to the specified depth using high-volume equipment that reaches every corner of the attic.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic run 10 to 15 degrees colder than the rest of the house in winter, or you’re seeing ice dams form along the roof edges after snowstorms.
What it costs in Running Springs
Blown in attic insulation in Running Springs generally falls between $1,800 and $3,800 for a typical cabin attic, including air sealing and bringing the R-value up to mountain-appropriate levels.
How we do it
We inspect the attic, seal penetrations and top plates, install vent baffles where needed, then blow insulation to a uniform depth that meets the R-value target we agree on before work starts.
What Blown In Insulation Costs in Running Springs
| Item | Typical range in Running Springs |
|---|---|
| Cellulose blown in (per sq ft installed) | $1.10 – $1.80 |

| Blown in fiberglass attic top-up | $0.90 – $1.50 per sq ft |
Is blown in insulation worth it in Running Springs?
Yes, and it usually pays for itself faster up here than anywhere else in Southern California because heating loads dominate the energy bill. A properly insulated Running Springs attic cuts heat loss dramatically and reduces ice dam formation. Call (866) 858-4033 for a free estimate specific to your attic.
Can you blow in insulation over old insulation in Running Springs?
In most Running Springs attics yes, as long as the old material is dry, not compressed, and free of mold or rodent damage. We inspect first and remove anything that would trap moisture against the ceiling. Call (866) 858-4033 and we’ll tell you if a top-up or full removal makes more sense.

Insulation retrofits typically don’t require a permit in San Bernardino County, but if the work is part of a larger remodel or involves structural changes to accommodate vaulted ceiling insulation, the county may want to see plans. We’ll flag it during the estimate if your project crosses that line.
Yes, and it’s common up here. We coordinate access with a property manager or neighbor, document the job with photos, and can send updates as work progresses. Many Running Springs second-home owners only come up on weekends, so we’re used to working around that schedule.
