Get answers to common questions about insulation services in Bloomington, Illinois.
For Bloomington's climate, which features hot, humid summers and cold winters with an average low of 16°F in January, a combination of air sealing and high R-value insulation is critical. We typically recommend blown-in cellulose or fiberglass for attics to achieve the recommended R-49 to R-60 level for our zone, as it effectively fills gaps and resists air movement that drives both heat loss and summer humidity infiltration.
Costs vary based on home size, existing insulation, and material, but for a standard 1,500 sq ft attic in Bloomington, homeowners can expect to invest between $1,500 and $3,500 for professional blown-in insulation to reach R-49. Regional material costs and the need for preparatory air sealing, which is highly recommended for Illinois homes to combat energy loss, are key factors in the final price. Always get itemized estimates from local contractors.
While insulation can be installed year-round, the ideal times in Central Illinois are late spring (April-May) and early fall (September-October). These periods typically offer mild, dry weather, which is safer for contractors working in attics and allows for proper ventilation during installation. Scheduling during these shoulder seasons also ensures your home is prepared before the extreme temperatures of our summer and winter hit.
Yes, Bloomington residents should first check for rebates from their utility provider, such as Ameren Illinois or ComEd, which often offer incentives for adding insulation to meet specific R-value targets. Additionally, the federal tax credits for energy efficiency (like the 25C credit) apply, which can cover 30% of qualified insulation material costs up to a $1,200 annual limit. A reputable local installer will be familiar with these programs.
Prioritize licensed, insured, and locally established contractors with strong references. Specifically, ensure they perform a thorough energy audit or inspection to identify air leaks—a major issue in our windy Illinois climate—before simply adding insulation. They should be knowledgeable about the 2021 Illinois Energy Conservation Code requirements and provide detailed quotes that separate material, labor, and air sealing costs.
