"I called for a free estimate & met with Jason. He was very helpful & knowledgeable about what could be done to improve the R rating in my new home. He suggested I apply for brand new offer regarding Avista's smart energy loan. I did & was accepted. USA insulation then sent a crew of 3 to blow insulation onto the attic & pump foam into the exterior walls. Eddie, Runfino & Jake did an excellent job! In the process, an electrical outlet over my counter-top was shorted out. Daryl the owner hired an electrician, Ehren from Electric Smith to fix the problem & he did so very well in a respectful & competent manner. I couldn't be more pleased with the work & effort that went into this job. Laci coordinated everything perfectly from USA insulation headquarters & answered all my questions, as well as ran down any "what a bouts" I asked about. Thank you so much to all involved! Kevin"

FAQs for spray foam insulation projects in Marsing, ID

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.
