INSULATION COMPANY ENGLEWOOD, CO
Insulation Contractors in Englewood, CO | Grizzly Insulation
The bungalow blocks off Broadway were framed before wall insulation was standard practice, and many still run on whatever heat their radiators can push through empty walls. Englewood’s compact, century-old housing is a specialty of ours: balloon-framed chases that need sealing, kneewall attics that need real insulation, and crawl-space cellars that need drying out. We quote each house on its own history, never from a template.

WHY LOCAL EXPERTISE MATTERS
Englewood’s Insulation Challenges
Three local realities shape every insulation job in Englewood, and shape how we quote, prep, and install.
Homes Older Than Insulation Itself
Much of Englewood was framed between 1900 and 1950, before wall insulation was code or custom. Empty balloon-framed walls, bare kneewalls, and attics with a token inch of fill are the daily reality here, and the upside is huge: no housing type gains more from an upgrade.
Radiator-Era Homes, Modern Energy Bills
Zone 5B swings hit hardest in houses built loose on purpose, when coal heat needed draft. Every gap that once vented a stove now drains a furnace, and Englewood’s small, tall floor plans stack the losses upward.
Old Foundations, Open Invitations
Stone and early-concrete foundations shift and gap with age, and the mature canopy over Englewood’s blocks keeps squirrels at fascia height. The South Platte and Little Dry Creek corridors add field rodents to the guest list every fall.

What Homeowners Say About Grizzly
★ ★ ★ ★ ★
Our 1926 bungalow near Broadway had literally nothing in the walls, you could feel winter through the plaster. Grizzly dense-packed what could be packed, foamed the kneewalls, and rebuilt the attic. The radiators finally get to rest.

Mice had been coming through our old foundation near Cushing Park for years. They covered every gap, cleared the attic mess safely, and blew in the pest-deterrent insulation. Quiet ever since, and the house holds heat better too.

Frequently Asked Questions
Common questions about insulation in Englewood, answered straight.
Climate Zone 5B calls for R-49 to R-60 in the attic, roughly 14 to 17 inches of blown-in cellulose. Many of Englewood’s pre-war bungalows carry an inch or two of century-old fill, functionally nothing. The free inspection gives you your exact number, photographed.
Yes, that is the point of dense-pack. Walls fill through small openings that get patched cleanly, kneewalls and dormers get foam from the attic side, and your plaster and trim stay untouched. Older homes are detail work, and they are most of what we do in Englewood.
It is with us. Old foundations and balloon framing give mice a highway system, and mature trees give squirrels the roofline. We close the entries with wildlife-grade materials, clean up safely, and can install borate-treated TAP insulation, one crew, one project.
They partner. Blown-in cellulose owns the open attic floor and dense-packs the walls; foam owns kneewalls, dormers, rim joists, and cellar walls where fiber underperforms. A century-old house usually gets a bit of both, specified room by room.
Yes. Englewood is Xcel territory, so qualifying insulation and air-sealing work earns utility rebates, plus the federal 25C credit covering 30% of qualifying costs up to $1,200 a year. Your estimate lists every credit that applies.
Most Englewood attics finish in one day. Add dense-packed walls or kneewall foam and two days is typical. Homes with knob-and-tube wiring get an honest conversation first, safety before insulation, always.
