HVAC, PLUMBING & ELECTRICAL.
DONE RIGHT SINCE 1925.

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. Was informed when Harrisen was going to arrive, wore booties in my home, and kept  me informed of his progress on our furnace maintenance. He  was extremely polite. Very professional. Always a good experience with this company!

 Trustindex verifies that the original source of the review is Google. I am happy to share our extreme pleasure with the outcome of our electrical project and the AJ Danboise contractor, MAHER KASSHAMOON, who got us there.

We had a multitude of electrical upgrades and repairs done to our home: electrical wiring added to ceilings that had none; electrical outlets, switches and dimmers added; recessed lighting installed throughout the home; new light fixtures and ceiling fans installed in most rooms, and repair of our outdoor electrical outlets.

This project affected the majority of the rooms in our home. Yet, despite its size, it was flawlessly executed by Maher. From the beginning (quoting process) to the end (project execution and completion), he was simply amazing!  He was professional, kind, customer-focused, knowledgeable and a problem-solver.  He helped us tremendously and has unquestionably earned our five star rating.  Thanks to him, the vision for our home has been brought to life.

Also, a special shout-out to Alex who worked with Maher in the earlier stages of the project. Alex was yet another amazing asset on the AJ Danboise team.  (Talent and skills apparently run deep in this organization and my husband and I were grateful beneficiaries of it.)
