"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!"

"Fantastic experience. Jeremy was awesome. Very honest and trustworthy! We received several quotes for attic insulation prior to selecting Energy Allies. Cannot say enough about customer relations. Jeremy and his brother were prompt, on time, and very competent in what they do. While trying not to bash the other companies that gave us quotes, all I will say is that their quotes and knowledge based compared to Energy Allies were, at best, suspect. As far as I am concerned Energy Allies (Jeremy & his brother) deserve 10 Stars!!"

Insulation questions, answered by experts

Insulation in Boise should be checked seasonally for signs of settling, moisture buildup, or pest activity, especially after heavy snow or rain. Attic insulation may need fluffing or topping off if it compresses over time. Crawl space insulation should be inspected for dampness or mold. Scheduling an energy audit every few years helps catch issues early and keeps your home efficient.

Helpful?

In Boise, be cautious of quotes that lack details about attic insulation type, R-value, or moisture control steps. Avoid professionals who rush you to sign or don’t explain their process. Reliable contractors will discuss ventilation, provide written estimates, and answer questions about materials. Always ask about warranties and ensure the company is familiar with Boise’s climate and local building requirements.

Helpful?

Your Boise home is likely a good candidate for insulation service projects if you notice uneven room temperatures, persistent drafts, or rising energy bills. Homes built before 1980 or with original attic insulation often benefit most. If you see ice dams in winter or feel temperature swings between floors, a professional energy audit or thermal imaging can pinpoint where upgrades are needed.

Helpful?

In Boise, insulation service projects can uncover hidden costs like the need for additional attic insulation, unexpected repairs to address moisture intrusion, or pest removal if rodents have damaged existing materials. Homes with older wiring may require electrical upgrades for safety. Also, city permits and inspection fees are often necessary, and sometimes ventilation improvements are needed to meet local building codes.

Helpful?

Boise’s climate—with hot, dry summers and cold, snowy winters—means insulation must handle both temperature extremes and moisture risks. Attic insulation should have a high R-value to prevent heat loss and resist shrinkage. Spring and fall are ideal for installation, as milder weather helps materials settle properly. Proper air sealing is crucial to prevent drafts and protect against Boise’s seasonal winds.
