Everyone who performs plumbing work in the State of West Virginia is required to have one (1) of the three (3) plumber certifications, regardless of the dollar amount of the job or the individual's affiliation with a licensed company. Plumbing work performed on a residential project $5,000 or more or on a commercial project $25,000 or more (total contract amount, not just the plumbing work) requires the individual/company to obtain a contractor license with the Plumbing classification. This requires taking the master Plumber or Plumbing exam and the WV Business & Law exam.

When do I renew my Plumber Certification?

The renewal date is listed on your certification card. In addition, you should receive a renewal form approximately forty-five (45) days before it is due to be renewed.
