Get answers to common questions about insulation services in Boise, Idaho.
For Boise's climate, which features cold winters and hot, dry summers, a combination of air sealing and high R-value insulation is most effective. We typically recommend blown-in cellulose or fiberglass for attics (targeting R-49 to R-60) and spray foam or dense-pack cellulose for walls to manage temperature extremes and improve energy efficiency. Properly addressing air leaks is crucial due to our frequent windy conditions, which can significantly increase drafts and heating costs.
Costs in the Treasure Valley vary based on home size, material, and scope, but a typical attic insulation project ranges from $1,500 to $3,500. Wall insulation is more complex and generally costs more. It's important to get multiple itemized quotes, as Idaho does not have a statewide insulation tax credit, but some local utilities like Idaho Power offer rebates for energy-efficient upgrades, which can offset the initial investment.
The ideal times are late spring (May-June) and early fall (September-October). These periods offer mild temperatures, making it easier for contractors to perform thorough work and for materials like spray foam to cure properly. Scheduling outside of the peak summer heat and winter cold also ensures better availability and can prevent urgent, costly heating losses during our coldest months, which often see temperatures in the 20s.
Always verify that the contractor is licensed, insured, and has strong local references. Look for companies experienced with Boise's specific building styles, from older craftsman homes to modern builds, and ask if they perform a pre-installation energy audit. A reputable provider will also be knowledgeable about the 2021 Idaho State Energy Code requirements and can help you navigate any potential rebate programs from local utilities.
Not always; the primary issue in many Boise homes is air infiltration, not just insufficient insulation. Our windy weather exacerbates drafts through gaps in attics, windows, and foundations. A professional assessment should first identify and seal these leaks—a process called air sealing. After sealing, adding insulation becomes far more effective at maintaining comfort and reducing high heating bills from our long heating season.
