"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!"

"I appreciated how thorough L2 was during the estimate visit, explaining options and how they could work for my house. I had L2 remove old blown-in in the attic and old batt in the crawl space, and then add baffles and blow in new insulation in the attic, and vapor barrier and spray foam in the crawl space. This took three days. The teams worked hard, protected my house carefully, and cleaned up every day before they left. They did a really excellent job. My only caveat is that L2 could be a bit more proactive about communicating scheduling. But they got right back to me when I asked."

"They were very professional and the quality of work was excellent. They stapled depth indicator strips on the attic rafters to ensure proper fill. When they found gaps around canned lights and brackets, they suggested filling them in with foam. I would definitely hire them again and recommend them to family and friends."

"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"

"My service request was to replace my kitchen faucet that was leaking. It was a Moen that probably cost close to $200. when it was installed years ago. My Moen was replaced with a faucet and spray nozzle that was pretty cheap that felt like a cheap plastic. My Ex husband made the comment, “WOW! Looks like they went all out and bought that faucet from dollar general! Let’s see how long that thing lasts!” I hate to admit it, but this time he was right. When I would turn on the faucet, the water stream had no pressure. It was like a string of water that came out of the faucet. I would have to use the spray nozzle in order to get a forceful stream. Well yesterday, I reached for the nozzle and it broke. (That faucet had been installed less than 5 month ago.) So now, I have a little stream of water coming from the faucet with a broken spray nozzle. I decided I’m just going to have my son replace the whole thing with a Moen. I’ve always had a great experience with AHS. I probably won’t use AHS again to replace faucet fixtures etc. (I notified AHS about the problem soon after the faucet/sprayer was installed, but they said I would need to put in another work order. I figured, it would just be replaced with another cheap faucet.)"

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.
