INSULATION COMPANY ARVADA, CO
Insulation Contractors in Evergreen, CO | Grizzly Insulation
Evergreen isn’t a subdivision — it’s a mountain community of cabins and custom homes scattered across the foothills at 7,000 feet and up. Older cabins and A-frames around Kittredge, Bear Creek, and the canyons were often built with little or no insulation, while newer Hiwan and Upper Bear Creek homes feature vaulted ceilings, exposed beams, and walls of glass that are notoriously hard to keep warm.
At this elevation the winters are long and cold, the snow load is heavy, and the sun is intense. Many homes heat with propane or wood, so every BTU is expensive — and the surrounding forest brings real wildfire exposure and steady pressure from mice, squirrels, and pack rats.
Colorado’s high country calls for R-49 to R-60 in the attic — and at 7,000 feet, more is better. Many Evergreen homes we inspect fall well short. Grizzly handles every service on this page across 80439.

Click any service below for the dedicated Evergreen-specific page with full details, process, and neighborhood context:
Blown-in cellulose to R-49–R-60, warmer rooms and lower Xcel bills for Evergreen’s ranches and two-story homes. Most attics finished in one day.
Closed-cell air-barrier foam for rim joists, cathedral ceilings, and the beamed, glassy assemblies of Evergreen’s mountain homes.
Sealing the ceiling plane against cold mountain air before insulation — because at 7,000 feet on propane heat, air sealing is where the savings start.
HEPA-filtered removal of old, settled, or rodent-soiled cabin insulation — clean deck, healthier air, disposal handled, ready for a proper reset.
Moisture-smart crawl space insulation and encapsulation for Evergreen’s cabins and hillside foundations, where frozen pipes are a real winter risk.
EPA-registered TAP® borate insulation adds thermal performance and rodent deterrence in one install — built for forest-surrounded Evergreen homes.
Spray foam and fiberglass systems for shops, warehouses, and offices along Highway 74 and Bear Creek Road, code-compliant, on schedule, minimal downtime.

WHY LOCAL EXPERTISE MATTERS
Evergreen's Insulation Challenges
Three local realities shape every insulation job in Evergreen, and shape how we quote, prep, and install.
From Rustic Cabins to Custom Mountain Homes
downtown Evergreen homes (1900s–1940s) hide empty wall cavities. Post-war ranches near Highway 74 average R-11–R-19, a third of Colorado’s R-49–R-60 standard. Newer builds meet only code minimums. Every era needs its own fix: dense-pack walls, attic top-offs, or targeted air sealing.
Front Range Climate Extremes
A mile above sea level, Evergreen swings 60 degrees in a week, subzero Januarys, high-altitude July sun, chinook winds. Freeze-thaw cycling opens gaps around can lights, flues, and framing. Insulation only performs here when paired with professional air sealing.
Open Space = Rodent Pressure
Greenbelts along Bear Creek, Evergreen Lake, and Evergreen Lake push mice toward warm attics every fall. Contaminated insulation loses R-value and hurts indoor air quality. Grizzly handles removal, exclusion, and pest-control insulation in-house, one crew, one visit.

REVIEWS
What Homeowners Say About Grizzly
★ ★ ★ ★ ★
We kept hearing scratching in the attic every October, and the upstairs bedrooms never held heat. Grizzly’s crew vacuumed out sixty years of filthy insulation, sealed the entry gaps, and blew in the pest-control insulation, all in one day. Two winters later: no mice, warmer bedrooms, and our January Xcel bill dropped noticeably.

“Our 1970s cabin near Bear Creek was impossible to heat — the propane bill was brutal. Grizzly dense-packed the walls, foamed the cathedral roofline, and air-sealed the attic. It finally holds heat, and our fuel use dropped dramatically.”

Frequently Asked Questions
Common questions about insulation in Evergreen, answered straight.
Evergreen sits in IECC Climate Zone 5B, where attics should carry R-49 to R-60. Many pre-1980 Evergreen homes measure R-19 or less, often a third of the standard. During a free assessment we measure your current depth at multiple points and show you the exact gap. See our Evergreen attic insulation page for what’s included.
Usually yes, and these homes see the biggest gains, because they started with so little. The typical fix is air sealing first, then blown-in insulation to R-49+. If your existing insulation is degraded or rodent-soiled, removal comes first. We’ll tell you honestly if your attic is already in good shape.
Yes, in-house. Homes near Bear Creek, Evergreen Lake, and Evergreen’s open space see steady rodent pressure. We remove soiled insulation with HEPA-filtered vacuums, seal entry gaps, and install EPA-registered borate-treated insulation that discourages nesting, one crew, one visit.
They solve different problems. Blown-in cellulose is the cost-effective choice for open attic floors where R-49+ is the target. Spray foam delivers the highest R-value per inch and doubles as an air barrier, ideal for rim joists, crawl spaces, and garages. Many Evergreen projects combine both.
Often, yes. Evergreen is in Xcel Energy territory, and qualifying insulation and air-sealing work can earn utility rebates, plus the federal 25C tax credit covers 30% of qualifying costs up to $1,200/year. Programs change, so we confirm current eligibility during your free estimate and help with documentation.
Most single-family projects finish in 1–2 days. An attic top-off with air sealing on a typical Evergreen ranch is often a single day. Whole-home projects touching the crawl space and rim joists may run two full days. You get a clear timeline with your quote, and we stick to it.
