INSULATION COMPANY ARVADA, CO
Insulation Contractors in Commerce City, CO | Grizzly Insulation
Commerce City is really two towns. The original south side holds modest 1940s–1960s working-class homes, many with minimal original insulation, near the refinery and rail yards. To the north, master-planned Reunion, Buffalo Run, and Belle Creek have exploded with new construction since the 2000s — big two-stories built to the code of their year (often R-38).
Out on the open plains beside the Rocky Mountain Arsenal refuge, Commerce City takes relentless wind and dust, and both halves of town lose real money through under-insulated attics. As a company headquartered here, we know these homes street by street.
Colorado sits in IECC Climate Zone 5B, which calls for R-49 to R-60 in the attic. Many Commerce City attics we inspect measure R-38 or far less. Grizzly handles every service on this page across 80022, 80640, and 80603.

WHY LOCAL EXPERTISE MATTERS
Commerce City's Insulation Challenges
Three local realities shape how we quote, prep, and install every Commerce City job — a split of old and new homes, open-plains wind, and Arsenal-edge wildlife.
Two Commerce Citys: Old South Homes & New North Builds
Commerce City’s homes split into two eras: 1940s–60s south-side houses that started with little insulation, and 2000s–2020s Reunion and Buffalo Run builds insulated to code-of-year (often R-38). Each needs its own fix — dense-pack, top-off, or a full reset.
Front Range Climate Extremes
On the open plains beside the Arsenal refuge, Commerce City takes strong, constant wind and blowing dust. That wind drives cold air through every framing gap around can lights, flues, and top plates. Insulation without air sealing can’t keep up here.
Open Space = Rodent Pressure
The Rocky Mountain Arsenal refuge, Second Creek, and the open prairie ring Commerce City with wildlife, and mice head for 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.

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 1958 south-side house was freezing and the bills were brutal. Grizzly — a company right here in town — dense-packed the walls, air-sealed the attic, and brought it to R-49. Warm for the first time in years, and the bills dropped fast.”

Frequently Asked Questions
Common questions about insulation in Commerce City, answered straight.
Commerce City sits in IECC Climate Zone 5B, where attics should carry R-49 to R-60. Many pre-1980 Commerce City 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 Commerce City 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 Second Creek, Barr Lake, and Commerce City’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 Commerce City projects combine both.
Often, yes. Commerce City 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 Commerce City 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.
All of them, original Commerce City to Reunion, ZIP codes 80002, 80003, 80004, 80005, and 80007. Our crew is based in Commerce City, about 20 minutes away via I-76, and we offer free estimates across the entire city and Jefferson County.
