INSULATION COMPANY ARVADA, CO
Insulation Contractors in Highlands Ranch, CO | Grizzly Insulation
Highlands Ranch is one of Colorado’s largest master-planned communities — roughly 100,000 residents in homes built mostly by Shea Homes and the Mission Viejo Company from the 1980s through the 2010s. That matters for insulation: an 80s or 90s home was built to the code of its day — often an R-30 attic — and has settled well below today’s standard.
The community climbs a high-plains ridge near 6,000 feet, where Front Range wind drives cold air through tract-home framing bypasses, and Douglas County carries some of the highest radon levels in the state. The 8,200-acre Backcountry Wilderness Area on the south edge keeps wildlife — and mice — close.
Colorado sits in IECC Climate Zone 5B, which calls for R-49 to R-60 in the attic. Many Highlands Ranch attics we inspect measure R-30 or less. Grizzly handles every service on this page across 80126, 80129, and 80130.

Click any service below for the dedicated Highlands Ranch-specific page with full details, process, and neighborhood context:
Blown-in and batt upgrades to R-49–R-60 — bringing 1980s–90s Village attics up from their original R-30. Most attics done in a day.
Closed-cell air-barrier foam for rim joists, bonus rooms over garages, and the vaulted great rooms that define Highlands Ranch floor plans.
Sealing the ceiling plane against ridge-top wind before insulation — because in a leaky tract home, air sealing is where the savings start.
HEPA-filtered removal of old, settled, or rodent-soiled material — clean deck, healthier air, disposal handled, ready for a proper reset.
Moisture- and radon-smart crawl space insulation and encapsulation for Highlands Ranch’s slab-and-crawl foundations.
EPA-registered TAP® borate insulation adds thermal performance and rodent deterrence in one install — built for Backcountry-adjacent Highlands Ranch homes.
Spray foam and fiberglass systems for the retail, offices, and light-industrial space around Highlands Ranch Town Center — off-hours, on schedule.

WHY LOCAL EXPERTISE MATTERS
Highlands Ranch's Insulation Challenges
Three local realities shape how we quote, prep, and install every Highlands Ranch job — code-era homes, ridge-top wind, and Backcountry wildlife.
A Master-Planned Suburb, Built to the Code of Its Day
Highlands Ranch homes span the mid-1980s Villages to the 2010s BackCountry. The catch is that 1980s–90s two-stories were built to an R-30 attic standard that has since settled and thinned — and their big footprints, bonus rooms, and vaulted great rooms multiply every weak spot. Each era needs its own fix: top-off, dense-pack, or a full reset.
Front Range Climate Extremes
Perched on a high-plains ridge near 6,000 feet, Highlands Ranch takes the full force of Front Range wind and wide day-to-night temperature swings. That wind finds every framing bypass in a tract home, and freeze-thaw cycling works gaps loose around can lights and flues. Insulation without air sealing can’t keep up here.
Open Space = Rodent Pressure
The 8,200-acre Backcountry Wilderness Area and the gulches threading through Highlands Ranch push mice toward warm attics every fall. Rodent-soiled insulation loses R-value and hurts air quality. We handle removal, exclusion, and borate-treated pest-control insulation in-house.

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 1994 two-story in Westridge had an ice-cold bonus room and sky-high winter bills. Grizzly air-sealed the attic and brought it from R-30 to R-49. The room is finally usable and the furnace runs half as much.”

Frequently Asked Questions
Common questions about insulation in Highlands Ranch, answered straight.
Highlands Ranch sits in IECC Climate Zone 5B, where attics should carry R-49 to R-60. Many pre-1980 Highlands Ranch 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 Highlands Ranch 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 Marcy Gulch, Chatfield Reservoir, and Highlands Ranch’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 Highlands Ranch projects combine both.
Often, yes. Highlands Ranch 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 Highlands Ranch 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.
