Get answers to common questions about insulation services in North Chicago, Illinois.
For our climate with cold winters and humid summers, attic insulation is the top priority to prevent heat loss. Air sealing and basement or crawl space insulation are also critical to combat moisture and drafts from Lake Michigan. We typically recommend high R-value materials like spray foam for air sealing or blown-in cellulose for attics to meet or exceed Illinois's recommended R-49 for attic spaces.
Costs vary by home size and material, but a typical attic insulation project in North Chicago ranges from $1,500 to $3,500. Spray foam is more expensive but offers superior air sealing. It's important to get itemized quotes, as local factors like older home construction (common in North Chicago) or accessibility can affect price. Many Illinois utilities offer rebates that can significantly offset the cost.
While insulation can be installed year-round, the ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild weather, making it easier for contractors to perform air sealing and for materials to cure properly. Avoid the peak of winter when attic work can be hazardous or mid-summer when extreme heat can affect installation.
Always verify the contractor is licensed, insured, and has strong local references. Look for companies experienced with North Chicago's mix of historic and modern homes. They should perform a thorough energy audit and discuss compliance with the 2021 Illinois Energy Conservation Code. Be wary of door-to-door sales and always get multiple written, detailed estimates.
Insulation is crucial, but in older North Chicago homes, air sealing is often the more critical first step. Gaps around windows, doors, and where the house meets the foundation let in cold Lake Michigan winds, making even good insulation less effective. A professional assessment will identify if you need insulation, air sealing, or both to achieve comfort and savings.
