Find a Plumber in Wyoming

Plumbers across Wyoming, license-checked before they reach you. Tell us the problem and your ZIP.

Wyoming handles plumber credentials differently than most states: there is no statewide plumber license, so cities and counties (Casper's Building Inspection Division, Cheyenne's Compliance Department) set their own requirements. Combine that with hard-freeze winters, and vetting a plumber takes local knowledge.

Plumber licensing in Wyoming

Wyoming has no statewide plumber license (the state licenses only electricians), so plumber credentials are handled by city and county building departments. Requirements differ by jurisdiction: Casper, for example, asks for a completed federally recognized plumbing apprenticeship or four years of experience in a plumbing shop holding a Casper license, plus proof of testing.

  • Authority. City and county building departments (e.g. City of Casper Building Inspection Division, City of Cheyenne Compliance Department); Wyoming has no statewide plumber license (the state licenses only electricians)
  • License structure. Varies by locality; for example, the City of Casper issues Plumbing Contractor, Master Plumber, Journeyman Plumber and Apprentice Plumber licenses, with the journeyman license requiring a federally recognized apprenticeship or four years of experience plus testing
  • Worth knowing. Where a city or county licenses plumbers, a plumber must hold that local license, and requirements differ between Wyoming jurisdictions. Casper, for example, requires a completed federally recognized plumbing apprenticeship or four years of experience in a plumbing shop holding a Casper license plus proof of testing.

What Wyoming conditions mean for plumbing

Hard freeze class means exactly what it sounds like in Wyoming: winters bite deep, frost drives far below the surface, and burst protection, insulated supply lines, and thorough winterization are yearly work in Cheyenne, Casper, and Laramie alike. Supplies vary utility by utility. Cheyenne's mountain-and-well blend averages a soft 60 mg/L (3.5 gpg) per its utility's own page, while Casper's unsoftened North Platte supply sits at the other end: the city's own 2002 report ranged it at 200-300 mg/L (11.7-17.5 gpg), still the newest figure published. The water quality report from your own supplier remains the number that matters.
