Our Story

A Michigan Family with Over a Century of Trust.

Alex Joseph Danboise opened a plumbing and hardware shop at Grand River and Spokane in Detroit in 1925. He wasn’t thinking about a hundred-year legacy — he was thinking about showing up and doing the job right. That part hasn’t changed.

His son Hall took over in 1966. Hall’s daughter Carol came to work alongside her father after college, and eventually brought in a young plumber named Jack Gatewood — who she later married. When Hall passed away in 1978, Carol and Jack stepped in and kept going. Jack earned his Master Plumber’s license and Mechanical Contractor’s license. Together they grew the business and moved it from Detroit to Redford to Farmington Hills, turning a neighborhood shop into the full-service company it is today.

In 2017, Carol’s daughter Amy became the fourth-generation owner. The fifth generation of the family is already learning the trades. A hundred years in, and it’s still the same family — still showing up for Metro Detroit homeowners one job at a time.
