HVAC, Plumbing & electrical. Done right since 1925.

Whatever your home needs, AJ Danboise has been the team that Metro Detroit homeowners call for 100 years.

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 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.

 Trustindex verifies that the original source of the review is Google. I honestly can't say enough good things about A.J. Danboise. They are an exceptional company, and I have trusted them with my home's heating, plumbing, and electrical needs for years.

I especially want to recognize Jeremy and Steve. Jeremy, in particular, has been servicing my boiler ever since it was installed, and his knowledge and expertise are truly outstanding. I live in a home that's over 100 years old, and anyone who owns an older home knows that it can come with some unique challenges, especially when it comes to heating systems.

Over the years, Jeremy has spent countless hours and made numerous service calls helping keep my boiler running properly. He knows my system inside and out. When an emergency comes up, he knows exactly what to look for, how to troubleshoot the problem, and how to get things back up and running. His ability to understand an older system, think outside the box, and find practical solutions is impressive.

More importantly, Jeremy gives me something you can't put a price on: peace of mind. Knowing that someone with his experience and knowledge is taking care of my heating system is incredibly reassuring. I have complete confidence in his work, and he is the one technician I trust with my boiler.

I also want to recognize the entire A.J. Danboise team. From heating and plumbing to electrical work, they have helped me maintain, repair, and improve my aging home. Everyone has been accommodating, professional, dependable, and trustworthy.

It's not easy finding a company you can rely on year after year, especially when maintaining a home that's more than a century old. A.J. Danboise has consistently earned my trust, and I wouldn't hesitate to recommend them to anyone.

Five stars without hesitation. Thank you, Jeremy, Steve, and the entire A.J. Danboise team for taking such good care of our home!

 Trustindex verifies that the original source of the review is Google. 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.

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!
