Get answers to common questions about insulation services in Spokane, Washington.
For Spokane's cold winters and dry summers, a combination of air sealing and high-R-value insulation is key. In attics, the recommended R-value is R-49 to R-60, typically achieved with blown-in cellulose or fiberglass. For walls, dense-pack cellulose is excellent for our older homes as it effectively fills cavities and reduces air infiltration, which is a major source of heat loss in our region.
Costs vary significantly based on home size, existing insulation, and the areas being insulated. For a typical attic upgrade to R-49, Spokane homeowners can expect to pay between $1,500 and $3,500. It's important to get multiple quotes, as regional material and labor costs apply. Remember, Washington State sales tax does not apply to labor for qualifying insulation services, which can affect the final price.
The ideal times are late spring (May-June) and early fall (September-October). These periods offer mild weather, making it easier for contractors to work effectively in your attic or crawl space. Scheduling during these shoulder seasons also ensures your home is prepared before Spokane's harsh winter sets in, and you'll avoid the high-demand backlog that often occurs in late summer and early winter.
Yes. Spokane follows the Washington State Energy Code, which sets minimum insulation requirements for new construction and major renovations. More importantly, check for current utility rebates. Avista Utilities, which serves Spokane, frequently offers rebates for insulation upgrades through their energy efficiency programs. Additionally, the federal tax credits for insulation (up to 30% of cost, with limits) are a significant financial incentive for qualifying improvements.
Prioritize your attic and basement or crawl space, as these are the primary areas for heat loss in our climate. Air sealing the attic floor and adding insulation there often provides the biggest return on investment and comfort improvement. In Spokane, many homes have vented crawl spaces that should be insulated at the perimeter walls, not the floor, to protect pipes from freezing and improve overall home envelope performance.
