Why Denver Homeowners Trust Grizzly
Blown-in insulation is the most efficient way to insulate an attic. Machine-blown fiberglass or cellulose settles into every joist bay, corner, and awkward gap that batts can’t reach, giving you consistent, gap-free coverage across the whole attic floor. It’s also the easiest way to top off insulation that has thinned or settled over the years. Installed to the right depth and density, blown-in insulation is one of the highest-return upgrades for a Denver home – warmer in winter, cooler in summer, and lower energy bills year-round.

Signs Your Home Needs Blown-In Insulation
Many insulation and energy-efficiency issues develop gradually, making them easy to overlook. If you’re experiencing any of the signs below, your property may benefit from a professional inspection.
High Energy Bills
If heating and cooling costs continue to rise, insufficient insulation or hidden air leaks may be forcing your HVAC system to work harder than necessary.
Drafts & Air Leaks
Noticeable drafts around doors, windows, attics, or crawl spaces can lead to energy loss and reduced indoor comfort.
Pest Activity or Contaminated Insulation
Rodents and pests can damage insulation, leave contaminants behind, and reduce its effectiveness over time.
Uncomfortable Attic or Crawl Space Conditions
Extreme temperatures, humidity, or poor ventilation in these areas can affect the comfort and efficiency of the entire building.
Uneven Room Temperatures
Hot and cold spots throughout your property often indicate inadequate insulation coverage or areas where conditioned air is escaping.
Old or Damaged Insulation
Settled, compressed, wet, or deteriorated insulation may no longer provide the protection your property needs.
Moisture, Humidity, or Mold Concerns
Excess moisture in attics or crawl spaces can contribute to mold growth, structural issues, and poor indoor air quality.

Questions Homeowners Ask Us Most
Blown-in (loose-fill) insulation is fiberglass or cellulose blown into place with a machine. It’s the most efficient way to cover attic floors and fill hard-to-reach spaces evenly.
Blown-in is ideal for attic floors, topping off existing insulation, and irregular or hard-to-reach spaces. Batts suit open, accessible framing like walls and new construction. We’ll recommend the right fit, or a combination of both.
Both perform well. Cellulose is denser and made from recycled material with fire and pest treatment; fiberglass is lighter and resists settling. We’ll advise based on your attic and budget.
Yes. Topping off settled or thin insulation with blown-in is one of the fastest, most cost-effective ways to restore your attic’s R-value.
Denver attics typically call for a high R-value. We measure your current depth and blow in to current Colorado recommendations.
