Where does your attic stand?
R-value measures how well insulation resists heat flow, the higher, the warmer your house stays. Here’s how typical Evergreen attics compare to the standard we install to:

TRUSTED PRODUCTS & PARTNERS
The Brands Behind Every Grizzly Install
We don’t install mystery material. Every Evergreen project uses products from the industry’s most trusted manufacturers.
01THE PROBLEM
Heat Rises. In Evergreen, It Leaves Through the Attic.
On a subzero mountain night an under-insulated attic bleeds furnace heat straight through the roof — and in Evergreen that heat often comes from expensive propane or a wood stove you have to keep feeding. A well-insulated attic is the single biggest thing keeping a mountain home warm.
AInsulation that settled decades ago
Evergreen’s older cabins in Bear Creek and Kittredge were built before insulation was standard; even newer Hiwan homes lose heat through vaulted ceilings and beam pockets. Insulation settles and thins over time, so what looks like a covered attic floor is often performing at half spec.
BAir leaks feeding the stack effect
Can lights, attic hatches, flues, and the gaps around log walls and beams leak warm air upward. Cold, dense mountain air makes that stack effect fierce — which is why we air-seal the ceiling plane before a single inch of insulation goes down.
CRodent-damaged material near open space
Each fall, mice, squirrels, and pack rats move from the surrounding forest into warm attics. Soiled insulation loses R-value and degrades indoor air quality, so it comes out — cleanly — before new material goes in.
DOld code minimums in newer neighborhoods
Even Hiwan, Evergreen Meadows, and Soda Creek homes from the 1990s–2010s were built to the code of their day, not to R-49–R-60. A one-day top-off closes the gap at the lowest cost per R-value.
02THE FIX
Two Proven Paths. One Honest Recommendation.
We inspect first, then recommend only what your attic needs, most Evergreen homes are best served by blown-in cellulose; some genuinely need foam.
03WHAT TO EXPECT
One Day on Your Street. Here's How It Goes.
A typical Evergreen attic insulation project, from first knock to final walkthrough:
We confirm the plan from your inspection, then protect flooring, HVAC equipment, and anything stored near the attic access.
Rodent-soiled or water-damaged material comes out through HEPA-filtered vacuums. Clean existing insulation stays and gets topped off.
Every can light, hatch, flue, and top-plate gap sealed with foam or caulk. Insulation over air leaks is money over a hole.
Rulers installed across the attic floor, then cellulose blown to the depth that delivers R-49+ after natural settling, 14 to 17 inches.
Depth checked and photographed at multiple points, work area cleaned, debris hauled away. You feel the difference that night.

"They measured our Evergreen Lake ranch at R-13, explained every line of the quote in plain English, and had air sealing plus new blown-in cellulose finished by the next afternoon. The floor-to-ceiling temperature difference is gone, the house finally feels even."

05QUESTIONS
Attic Insulation in Evergreen, Answered Straight
Evergreen sits in IECC Climate Zone 5B, where attics should carry R-49 to R-60, roughly 14–17 inches of blown-in cellulose. Most pre-1980 Evergreen homes we inspect measure R-11 to R-19. Your free assessment includes depth measurements at multiple points, so you see the exact gap in inches before any quote.
Four factors set the price: attic square footage, current R-value, air-sealing scope, and whether old material needs removal. You get a fully itemized written quote after a free inspection, and Xcel Energy rebates plus the federal 25C tax credit (30% of qualifying costs, up to $1,200/year) reduce the net cost for most Evergreen projects. Financing is available.
Blown-in cellulose is the cost-effective answer for open attic floors and top-offs, that’s most Evergreen homes. Spray foam earns its premium when HVAC equipment lives in the attic, ceilings are vaulted, or ice dams keep returning. We inspect first and recommend only what your attic needs.
Only when necessary. Clean, dry material gets topped off, the budget-friendly path. Rodent-soiled, moldy, or water-damaged insulation comes out first via HEPA-filtered removal. Homes near Bear Creek, Evergreen Lake, and Evergreen Lake need this most often.
Most Evergreen attics are air sealed and insulated in a single day, removal projects typically run one to two days. Your quote includes a firm timeline, and we stick to it.
In most cases, yes. Ice dams form when attic heat melts roof snow that refreezes at the cold eaves. Air sealing plus R-49+ insulation removes the heat source, the permanent fix, versus roof rakes and heat cables that only treat the symptom. We correct attic ventilation where needed too.
