Re-insulate to current Denver code standards (R-49 to R-60)
Complete removal + replacement in one project
A proven, methodical approach refined over 20+ years of professional installation.
We inspect your attic insulation to assess its condition, identify contamination or damage, and recommend removal + replacement vs. other approaches.
Containment barriers are set up, and old insulation is extracted using HEPA-filtered industrial vacuums. Material is collected in sealed bags for disposal.
With the attic cleared, we inspect for roof leaks, pest entry points, mold, and other issues. The attic floor is sanitized and prepped for new insulation.
New blown-in insulation (or spray foam) is installed to the specified R-value, with depth verification to ensure you're getting full-performance insulation.
Old attic insulation in Denver homes can become a serious liability. Fiberglass batts compress and lose R-value over time, cellulose settles and thins out, and any insulation type can be contaminated by roof leaks, ice dams, rodents, or mold. When your attic insulation is no longer performing — or is actively causing indoor air quality problems — removal and replacement is the best path forward. Sky Insulation provides complete attic insulation removal using industrial-grade HEPA vacuum systems that safely extract old blown-in cellulose, fiberglass batts, and other materials without spreading dust and debris into your living space. After removal, we sanitize the attic floor, inspect for hidden issues (roof leaks, pest entry points, electrical hazards), and install new insulation to current Denver energy code standards of R-49 to R-60. This full-service approach delivers dramatically better results than simply adding new insulation over old, damaged material. You get a clean starting point, the opportunity to address any underlying issues, and new insulation performing at its full rated R-value from day one.

Removing old insulation completely eliminates accumulated dust, allergens, pest contamination, and degraded material — giving you a clean foundation for new insulation.
Old attic insulation harbors allergens, dust mites, rodent droppings, and mold spores that can affect your indoor air quality. Removal eliminates these sources.
Removal reveals hidden problems like roof leaks, pest entry points, and electrical hazards that can be fixed before new insulation is installed.
New insulation installed on a clean, properly prepared surface performs at its full rated R-value — unlike new insulation added over old, degraded material.






We use industrial-grade HEPA-filtered vacuum systems to safely extract old insulation from your attic. The material is collected in sealed bags and disposed of properly. Containment barriers prevent dust from entering your living space.
If your existing insulation is in good condition (no moisture damage, pests, or mold), adding blown-in insulation on top is a cost-effective option. If it's damaged, contaminated, or severely compressed, removal and replacement delivers much better results.
Most residential attic removal projects take 1–2 days depending on the attic size and insulation type. Replacement is typically done on the same day as removal or the following day.
Yes. All removed insulation is bagged, transported, and disposed of in compliance with local regulations. You don't need to arrange any disposal yourself.
