Insulation Company in Running Springs, CA
Blown in insulation is the workhorse fix for most Running Springs cabins and mountain homes, filling the wall cavities and attic floors that were skipped when these places were built as summer getaways in the 1960s through 1980s. We’re Willow Insulation, and we’ve been working at 6,000 feet long enough to know that a Running Springs house needs a different insulation plan than a flatland rancher in Highland. Thin walls, vaulted ceilings, and snow that sits on the roof for weeks all change what material goes where. Call (855) 473-6541 and we’ll walk you through what your place actually needs.
Why Running Springs Homes Are Different
Running Springs sits at roughly 6,000 feet in the San Bernardino Mountains, where the same house can face 100°F summer afternoons and freezing, snow-loaded winters within months. Insulation here can’t be a one-season product. It has to slow heat coming in during July and stop heat leaking out during January, all while handling the moisture that comes with snowmelt and ice. Most of the housing stock is 1960s to 1980s wood-framed cabins, chalets, and A-frames, many originally built as vacation homes with thin or no insulation, single-pane windows, and vaulted exposed-beam ceilings. Those vaulted ceilings are the Running Springs signature problem: there’s no attic to blow into, so heat escapes straight through the roof deck, melting snow into ice dams and icicles at the eaves. A flatland crew that only does standard attic blow-in won’t know what to do with a rafter bay that’s only six inches deep. We work with dense-pack and rigid foam techniques in those assemblies, and we think about fire-resistant detailing because this is a steep, wildfire-prone mountain zone where embers land on roofs and vents.
Our Main Running Springs Services
Most Running Springs homeowners call us about two things: getting the attic or roof assembly properly insulated for winter, and sealing the house with spray foam where air leaks are driving energy bills and ice problems. Here’s what each one involves up here.
Attic Insulation in Running Springs
Attic insulation in Running Springs means working around vaulted ceilings, shallow rafter bays, and snow-load concerns. Many cabins have a small attic over part of the floor plan and exposed beams over the rest, so we often combine blown-in coverage on the flat attic floor with dense-pack or rigid foam at the sloped sections. We check venting carefully because trapped moisture under a snow-covered roof causes rot and mold. For homes with accessible attics, we blow cellulose or fiberglass to a depth that makes sense for this elevation. For the vaulted sections, we work from below or remove decking as needed. Read the full breakdown on our Attic Insulation in Running Springs page.
Spray Foam Insulation in Running Springs
Spray foam handles the air leaks that fiberglass and cellulose can’t, and in a mountain house, air sealing is often half the comfort battle. Running Springs cabins leak through rim joists, cantilevered floors, and the gaps around old single-pane windows. We install both open-cell and closed-cell foam, with Icynene and Demilec systems on the roster, depending on whether the assembly needs moisture protection or just an air barrier. Closed-cell foam is especially useful in shallow rafter bays where every inch of R-value counts and where snow-driven moisture is a concern. See the full Spray Foam Insulation in Running Springs breakdown for details.

Blown In Insulation in Running Springs
Blown in insulation in Running Springs is the most cost-effective way to add R-value to an attic floor or a wall cavity that was never insulated, and it’s our most-requested service for these mountain cabins. Because so many Running Springs homes were built as summer cabins with little or no insulation, blown-in cellulose or fiberglass lets us fill the irregular spaces those old wood frames leave behind. We carry GreenFiber cellulose as a recycled-content option, and it’s our go-to for Running Springs attic floors because it settles into odd rafter bays and stops the air movement that drives ice dam formation. For a deeper look at the method itself, see our Blown In Insulation hub.
Cellulose Insulation
Signs you need it
Rooms over the top floor run hot in summer and cold in winter, and your heating bills climb every snow season because the attic floor has thin or no insulation.
What it costs in Running Springs
Cellulose insulation in Running Springs typically runs $1,500 – $3,200 for a full attic floor or wall cavity project, depending on depth and square footage.
How we do it
We dense-pack or loose-fill GreenFiber cellulose using a hose and blower, filling every bay to the target R-value and air-sealing the major leak points first.
Blown In Attic Insulation
Signs you need it
You see bare spots on the attic floor where old fiberglass has settled or been pulled back, and the snow on your roof melts in patchy bands while neighbors’ roofs stay white.
What it costs in Running Springs
Blown in attic insulation in Running Springs typically falls between $1,900 and $3,900, with the final number set by attic size, access, and target depth.
How we do it
We seal top plates, chases, and can lights, then blow to a consistent depth across the whole attic floor, including the edges where heat loss is worst.
Blown In Fiberglass Insulation
Signs you need it
You want an insulation that won’t settle as much as cellulose and prefer a material that’s naturally non-combustible in a wildfire-prone zone.
What it costs in Running Springs
Blown in fiberglass insulation in Running Springs typically runs $1,800 – $3,800, based on the R-value target and how much old material needs to come out first.
How we do it
Using Owens Corning fiberglass, we blow a consistent layer across the attic floor or into wall cavities, keeping the material dry and fluffed for full thermal performance.
