"I only needed part of my attic insulated and brought up to code. I had others try to sell me lots of services I didnâ t need, nor ask for. Denver Insulation came out, measured the area, and gave me a straight forward quote. Work was very fast and professional."

"Jason and the crew were very professional. After talking with multiple contractors the choice was clear. I was given 3 options for insulation. Reg blown, closed cell on deck with blown, or full blown deck and bottom of the roof. We chose to go with foam bottom and blown on top of it. These guys had nice equipment and were fast and accommodating to schedule. So happy we chose Advanced Insulation Solutions to do the work! Thanks again!"

"Since we had squirrel damage on some electrical wiring in the attic, we hired them to first remove the old insulation so the electrician could more easily do the wiring repair. Cost more to remove the old stuff (old and worthless), but it saved $500 on the electrical work bill. After the electrical work was done, they came back and filled in the attic with R49. The guys doing the the removal and installation work were great, and it went quickly and efficiently. Terry was a good guy to work with for estimates and scheduling, and Brian for invoicing. Overall, we are very happy. Wish that work with all home contractors went this well."

FAQs for spray foam insulation projects in Westminster, CO

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
