Need a Plumbing Contract in Wisconsin? AroundWire Can Help

In Wisconsin, plumbing service contracts typically require contractors to hold a valid Wisconsin Master Plumber or Journeyman Plumber license, issued by the Department of Safety and Professional Services (DSPS), and to comply with the Wisconsin Plumbing Code (SPS 381-387). Contracts often specify adherence to local municipal ordinances, as many cities and counties in Wisconsin have additional permitting and inspection requirements. Standard agreements include detailed scopes of work, timelines, and clear payment schedules—often with progress payments tied to inspection milestones. State law requires minimum insurance coverage, including general liability and, where applicable, workers’ compensation, with many clients requesting certificates of insurance as a condition of contract award. Risk allocation clauses commonly address unforeseen site conditions, change orders, and warranty obligations (usually one year per Wisconsin Statute 895.07). Contracts must comply with Wisconsin’s prompt payment statutes, which generally require payment within 30 days of invoice approval for public projects. Dispute resolution typically favors mediation or arbitration before litigation, in line with local industry practices. Wisconsin’s Home Improvement Practices Act (ATCP 110) applies to residential plumbing contracts, mandating written agreements and specific consumer protections. Prevailing wage requirements may apply for certain public projects. It is standard for contracts to include indemnification and hold-harmless provisions, especially when working for public entities or large private clients.
