Insulation Services in Greenville, SC
Greenville SC insulation upgrades pay back fast given Duke Energy rates and SC's heat-humidity. Most pre-1990 Greenville homes have R-19 to R-30 attics — well below the modern R-49+ target. Air sealing before insulation matters in older Botany Woods homes. Duke Energy rebates available. NeedInstall connects you with Greenville insulation contractors who handle Duke paperwork, blower-door testing, and proper detailing.
Greenville attic top-up to R-49+: $1,800-$4,500. Wall dense-pack: $4,500-$11,000 retrofit. Basement spray-foam: $4-$7 per board foot. SC requires a state contractor license. Duke Energy rebates ($300-$1,500). Blower-door test ($300-$500) often required.
