"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!"

"I was very pleased with the pricing structure (I compared to 2 other quotes). Jason Montgomery also helped me with an issue in another part of the house at no cost. Thanks. My only request would be a picture of completed work (even from his phone) showing the depth of insulation since I don't climb ladders to attic."

FAQs for spray foam insulation projects in Littleton, 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.
