Poor John's Plumbing was founded by Daryl Welker in 1987. He created the company in hopes of providing a better living situation for his family. He met his wife and business partner in 1995. They ran the business together until 2014. Their son and nephew now operate the business to carry on their legacy.
Missouri does not issue a statewide electrical, plumbing, handyman and general contractor license and delegates licensing and permitting process to the local permitting authority of the city the contractor works in. So a contractor you consider to hire must be in compliance with any local jurisdiction regulations.
