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 fourth 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.

Had our seasonal furnace inspection and the technician, Silvio, took his time to clean the furnace and check that all was functioning properly. There were no issues and no subsequent charges due to being in the maintenance plan. That is a proof of integrity as a problem was not manufactured. It is a reason AJD gets the job when we need it done. Silvio and AJD techs are professional and friendly and customers get an email in advance of appointments with technician details including an image of the technician for safety as you’ll recognize them when they arrive. An arrival ETA is also provided and show covers are put on at the door. They are a great company and we’ve been customers since 2018.

Jeremy was absolutely amazing! We truly appreciate him taking the time to thoroughly inspect our entire boiler and making sure nothing was overlooked. He was professional, knowledgeable, and incredibly thorough. It’s clear he takes pride in his work and doesn’t cut corners. I would recommend him 1,000% without hesitation!

Electrical work was performed today by Harrisen and Alex from AJ Danboise. Five stars just doesn’t seem enough. Harrisen and Alex arrived on time, were professional, friendly, honest and all work was completed timely and was reasonably priced. I definitely recommend AJ Danboise and will use them again in the future. Thank you!

Brandon completed our annual HVAC inspection, noted some condensate media needed replacement and completed the task for us. He also completed a thorough review of our entire HVAC system and declared it in top condition. We have been very happy with everyone we’ve worked with from AJ Danboise and regularly recommend them to family and friends. They understand what excellent customer service is and they deliver.

Maher was an expert electrician and communicator. He diagnosed the problem with our bathroom fan, explained it to us, and left to find us a new motor, even though it was the end of his working day. He returned with the motor, installed it, and our problem is solved. Thank you, Maher! Wonderful experience!
