Our Story

A Michigan Family with Over a Century of Trust.

""
sheild

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.

Michigan doesn’t go easy on home systems. When your furnace or AC goes out, we can usually get there the same day — upfront price before we touch anything, Trane equipment on every install, and GoodLeap financing available for qualifying replacements.

We got water leaking issues from shower room and asked the investigations to A.J. Danboise. Their technician John looked out the issue and explained to me the reason very kindly! We need to work with my insurance company but I really appreciate his service!!

Brandon was quick and thorough. Thankfully, our furnace is in good working condition for the upcoming winter, but having that additional confirmation as reassurance is a plus. Brandon was happy to answer other questions I had regarding our water filter attached to the furnance.

Everyone I spoke with was very friendly over the phone.  The appointment was easy to make and we were even able to move the appointment up, which worked great for us.  Tim the technician was very nice and knowledgeable.  He didn't mind me asking questions and hanging out watching what he was doing.  This is our second time calling AJ Danboise and  I would definitely call them again with any issues we have in the future. Update: I called AJ Danboise last night at 9pm because we had a furnace issue. Someone was at my house the next morning by 9:30am to look into the issue. Chris was quick to identify the issue, and explain it to me. He was able to fix the problem within a few minutes after getting the part and we we had heat again.  I've always had great experiences with the technicians and schedulers. Update: Sept 2026 - called AJ about having our plumbing inspection and making sure we had backflow preventers on our sprinklers and outside spigots. Jake listened to my requests and was quick, kind and helped me understand my options before installing anything.
