Dupont Sealcoating

Dupont Sealcoating is a family-run, owner-operated business in Merrimack that says it has served the Merrimack and Nashua area since 2007. The company focuses on driveway and parking-lot sealcoating, hot rubber crack sealing, patch repair, striping, and sweeping or cleaning, and says it uses commercial-grade materials and state-of-the-art equipment. Homeowners consistently describe completed driveway sealcoating and crack repair as professional and thorough. Recent reviews praise quick communication, punctuality, easy coordination, quality products, and responsive follow-up when patching was needed; older reviews also describe repeat maintenance and detailed work. Before booking, ask for a written estimate that spells out preparation, patching, crack treatment, drying expectations, and any striping or sweeping included. The company advertises free estimates and local references, but the available material does not establish insurance, a license, or an emergency service offering. Dupont looks suited to Merrimack and Nashua homeowners or property managers seeking routine asphalt maintenance and driveway or lot sealing.
