"We recently had insulation work done by commandos Insulation and the entire experience was excellent from start to finish. The team was professional, punctual, and very knowledgeable. They explained the process clearly, completed the job efficiently, and left everything clean afterward. Their attention to detail and customer service really stood out. I would highly recommend them to anyone looking for quality insulation work at a fair price!"

"This company and team really went a few extra miles for us, including multiple trips and lots of extra hours down here to Pullman where we live. Very courteous, and determined to get everything right before saying the job was done. Highly recommend! They blew insulation into our attic, installing baffles; and injected expanding insulation into our walls. Daryl and his team are fantastic."

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

FAQs for spray foam insulation projects in Idaho City, 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.
