Chicago insulation upgrades pay back fast given ComEd/Peoples Gas rates and IL's brutal winters. Most pre-1990 Chicago homes have R-19 to R-30 attics — well below the modern R-49+ target. Air sealing before insulation matters in older brick row homes. ComEd rebates available. NeedInstall connects you with Chicago insulation contractors who handle ComEd paperwork, blower-door testing, and proper detailing.
Chicago attic top-up to R-49+: $2,200-$5,500. Wall dense-pack: $4,500-$11,000 retrofit. Basement spray-foam: $4-$7 per board foot. IL requires a state contractor's registration. ComEd rebates ($300-$2,000+). Blower-door test ($300-$500) often required.
