DAP & Son

DAP & Son is an Insulation contractor serving Chicago, helping homeowners and businesses reduce drafts, control moisture, and lower energy bills through targeted upgrades. Request an on-site assessment and ask them to check current R-values, perform air-sealing recommendations, and outline improvements for attics, walls, and crawl spaces. Compare material options (spray foam, blown-in cellulose, fiberglass) with clear pricing, available rebates/incentives, warranties, and an estimated payback period. Before scheduling, confirm licensing and insurance, timeline and cleanup plan, and ask about add-ons like soundproofing or ice-dam prevention to boost comfort year-round.
