INSULATION COMPANY SHERIDAN, CO
Insulation Built for Sheridan, From Old Sheridan to River Point
Sheridan grew as a small working-class town along the South Platte. Old Sheridan holds compact postwar bungalows and ranches — often with almost no insulation to begin with — while newer neighborhoods like River Point, Bear Creek, and around the South Platte were built to 1990s–2000s code minimums. Each era needs a different fix.
Sitting in Arapahoe County along the South Platte just south of Denver, Sheridan also sees strong Front Range wind, hard freeze-thaw swings, and the wind and hail the metro sees each year. A tight, well-insulated envelope is about comfort, efficiency, and resilience all at once.
Colorado sits in IECC Climate Zone 5B, which calls for R-49 to R-60 in the attic. Many older Sheridan homes we inspect measure R-19 or less — and the oldest measure close to zero. Grizzly handles every service on this page for homeowners across 80110.

Blown-in and batt upgrades to R-49–R-60 — from near-zero Old Sheridan cottages to code-minimum River Point homes. Most attics done in a day.
Closed-cell air-barrier foam for rim joists, additions, and the wind-exposed assemblies of Sheridan’s older and newer homes alike.
Sealing the ceiling plane against Front Range wind before insulation — because in a leaky postwar cottage, 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-smart crawl space insulation and encapsulation for Sheridan’s older cottages and Bear Creek-corridor foundations.
EPA-registered TAP® borate insulation adds thermal performance and rodent deterrence in one install — built for open-space-adjacent Sheridan homes.
Spray foam and fiberglass systems for Old Sheridan’s River Point storefronts, offices, and light-industrial space — off-hours, on schedule.

WHY LOCAL EXPERTISE MATTERS
Sheridan's Insulation Challenges
Three local realities shape how we quote, prep, and install every Sheridan job — from bungalows and ranches to open-space wildlife.
From Older Homes to New Subdivisions
Sheridan’s homes span the postwar to today. Old Sheridan’s bungalows and ranches often have empty wall cavities and next to no attic insulation; the 1990s–2000s builds in River Point and Bear Creek carry code-minimum R-19. Each needs its own fix — dense-pack, top-off, or a full removal and reset.
Front Range Climate Extremes
Sheridan sits along the South Platte just south of Denver, where temperatures swing sharply and Front Range wind pushes cold air through every gap. Freeze-thaw cycling works openings loose around can lights, flues, and framing. Insulation without air sealing simply can’t keep up here.
Open Space = Rodent Pressure
Bear Creek, the South Platte, and the open space around Sheridan funnel 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 Old Sheridan cottage had almost no insulation and a furnace that never caught up. Grizzly 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 Sheridan, answered straight.
Sheridan is in Climate Zone 5B, where attics should carry R-49 to R-60 — roughly 16–20 inches of blown-in insulation. Old Sheridan cottages often measure near zero; even 1990s River Point homes measure R-19 or less. A free assessment shows exactly where you stand.
Almost always — the bungalows and ranches have the most to gain because they started with so little. We often dense-pack the empty walls and air-seal first, then top the attic to R-49+. Degraded or rodent-soiled material comes out before new goes in.
Yes, in-house. Bear Creek, the South Platte, and Sheridan’s open space put homes near steady rodent pressure. We remove soiled insulation with HEPA vacuums, seal the entry points, and install borate insulation that resists nesting.
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 Sheridan projects combine both.
Often, yes. Sheridan 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 Sheridan 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, Old Sheridan to River Point, 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.
