For property owners and managers, J&J’s sealcoating warranties add something especially valuable to a pavement maintenance project: protection after the work is complete. At J&J Enterprises, completing a project is only part of the commitment. Our qualifying sealcoating services are backed by written warranty protection covering qualifying defects in materials and workmanship. Depending on the sealcoating system selected, J&J offers two-year or five-year warranty protection.
