Your Attic Is Costing You Money

Your attic is the single most important area to insulate. Heat rises. Without proper attic insulation, you're losing 25-35% of your heating and cooling through your roof.


In Colorado, proper attic insulation means staying warm when it's -10°F outside and cool when it's 95°F in summer. It also prevents ice dams that damage your roof.



We install all types of attic insulation. We'll recommend what works best for your home and budget.

Why Attic Insulation Matters in Colorado

Extreme Temperature Swings

Northern Colorado goes from below zero in January to over 90°F in July. Your attic can reach 150°F in summer and -20°F in winter.



Without proper insulation, your HVAC runs constantly. Your energy bills stay high no matter what you do.

Ice Dams Damage Roofs

Ice dams happen when warm air escapes into your attic. This melts snow on your roof. The water runs down and refreezes at the edges.



Ice dams cause thousands of dollars in damage. They're extremely common in Denver, Fort Collins, and the Front Range. Proper attic insulation prevents them.

Old Homes Need Upgrades

Many Colorado homes were built in the 1960s-80s with minimal insulation. Building codes now require much higher R-values.



If your attic has less than 10 inches of insulation, you need more. Most Colorado attics should have 14-18 inches.

High Energy Costs

Xcel Energy and other Colorado utilities have raised rates significantly. Every bit of wasted energy costs more now.



Upgrading your attic insulation can cut your heating and cooling costs by 30-50%. Most homeowners see payback within 3-5 years.

Common Questions About Attic Insulation

    For a typical 1,500 square foot attic in Colorado:


    • Blown-in cellulose: $2,000-$3,500
    • Blown-in fiberglass: $2,500-$4,000
    • Spray foam: $4,500-$7,500

    This includes air sealing and proper installation. Call 303-596-3107 for your free estimate.

  • How much will I save on energy bills?

    Most Colorado homeowners save $30-60 per month in winter and $20-40 per month in summer. That's $400-$800 per year.


    Your exact savings depend on your current insulation, home size, and energy rates. We can calculate your estimated savings during inspection.

  • Can I add insulation over what I have?

    Usually yes, if your current insulation is:


    • Dry and in good condition
    • Not compressed or damaged
    • Not contaminated by pests or mold

    We can blow new insulation right on top. This is the most affordable upgrade option.

  • Will more insulation cause moisture problems?

    No, if your attic is properly ventilated. We always check ventilation first.


    Problems only happen when ventilation is blocked or insufficient. We ensure proper airflow during installation.

  • How long does attic insulation last?

    • Blown-in cellulose: 20-30 years
    • Blown-in fiberglass: 30-50 years
    • Spray foam: Lifetime of the home

    All types settle or compress slightly in the first year. After that, they remain stable for decades.

  • What about my attic access door?

    We insulate and weatherstrip your attic access door. This is often a huge air leak.


    We install an insulated cover or ensure your existing hatch is properly sealed.
