Get answers to common questions about insulation services in Frankfort, Illinois.
For our climate with cold winters and hot, humid summers, blown-in cellulose or fiberglass in attics is often the most cost-effective upgrade. It provides excellent thermal resistance (R-value) and air sealing, directly combating the significant temperature swings we experience. Spray foam, while more expensive upfront, offers superior air sealing and moisture control, which can be a wise long-term investment for older Frankfort homes with draft issues.
The ideal times are late spring (April-May) and early fall (September-October). These periods typically offer mild, dry weather, which is crucial for proper installation of materials like spray foam and for effective attic work. Scheduling during these shoulder seasons also helps you avoid the peak summer heat and the busy winter rush when homeowners are urgently addressing high heating bills.
Yes, there are important local incentives. ComEd and Nicor Gas offer substantial rebates for adding insulation in Illinois, which can significantly reduce your project cost. Furthermore, all work must comply with the 2018 International Energy Conservation Code (IECC) adopted by Illinois, which specifies minimum R-value requirements for our climate zone. A reputable local contractor will handle this permitting and compliance for you.
Look for a licensed, insured contractor with specific experience in our region. They should perform a thorough energy audit or assessment before quoting. Check for strong local references in towns like Frankfort, Mokena, or New Lenox and verify they are a certified installer for the products they use. Be wary of door-to-door sales or extreme low-ball quotes that may indicate subpar materials or workmanship.
Insulation works in tandem with air sealing. In many historic or older Frankfort homes, air leaks around windows, doors, and attic penetrations are a major source of discomfort and energy loss. A comprehensive approach that includes air sealing (like caulking and weatherstripping) *before* adding insulation is critical. This addresses the draft directly and ensures your new insulation performs at its maximum efficiency.
