Our Process

How Our Attic Insulation Process Works

We keep it straightforward: inspect, seal, install, and verify. No surprises, just a tighter, more efficient home.

  1. Inspect Your Attic — We check current insulation levels, air leaks, and ventilation to identify where you're losing energy.
  2. Seal Air Leaks — We close gaps around pipes, vents, and attic hatches with caulk and foam to stop drafts.
  3. Install Premium Insulation — We blow in fiberglass or cellulose to the recommended R-value for Denver's climate, using materials from trusted brands like Owens Corning or CertainTeed.
  4. Verify and Clean Up — We measure final depth, check for even coverage, and leave your attic clean. Then we walk through what we did and answer any questions.

Real Results from Denver

How We Saved a Family $180/Year on Energy Bills

Last winter, a home in the Berkeley neighborhood had ice dams and sky-high heating costs. We fixed it with blown-in attic insulation and air sealing.

In December 2024, we worked on a 1950s bungalow near 38th & Tennyson. The owners were paying $320/month for gas heat and had visible frost on the attic decking. We removed the old, settled fiberglass batts, air-sealed all top-plate penetrations and recessed lights, then blew in R-49 of CertainTeed Optima fiberglass. Total job: 1 day, $2,400. The next month their heating bill dropped to $210 — a 34% savings. Plus, no more ice dams. They called us back in spring to replace their hail-damaged shingles.

Common Questions

Attic Insulation FAQs from Denver Homeowners

We get a lot of questions about attic insulation here in Denver. Here are the answers, straight from our crew.

How much does attic insulation cost in Denver?

Cost varies by attic size and insulation type. For a typical Denver home (1,500–2,000 sq ft), blown-in fiberglass runs $1.50–$2.50 per sq ft, while spray foam is $3–$5 per sq ft. We provide free estimates for your specific attic.

Is attic insulation worth it in Denver?

Absolutely. Denver's climate means hot summers and cold winters. Proper attic insulation can lower energy bills by 15–20% and prevent ice dams. Most homeowners recoup the cost in 2–4 years.

Can I DIY attic insulation?

You can, but we don't recommend it. Attic work is dangerous—hot, cramped, with electrical hazards and potential asbestos. Plus, improper installation reduces R-value. We handle everything safely and correctly.

What R-value is recommended for Denver attics?

Denver is in Zone 5B. The DOE recommends R-49 to R-60 for attics. We typically install R-49 blown-in fiberglass or R-38 spray foam, depending on your roof structure and budget.

Do you remove old insulation before installing new?

We inspect first. If old insulation is wet, moldy, or rodent-damaged, we remove it. Otherwise, we can blow new insulation over existing material. We'll advise you during your free roof inspection.

Does attic insulation help with roof repairs?

Indirectly, yes. Poor insulation causes ice dams that damage shingles and gutters. It also leads to condensation that rots decking. Adding insulation extends your roof's life and prevents costly repairs.
