Pipe Doctor is such a pleasure to work with the customer service department is so efficient. The plumbers were on time and a pleasure to work with. Mike G is a real professional not only is he meticulous in his work, he cleans up and makes the place look cleaner than when he would started. Would highly recommend their service.

I have been following Mikey Pipes/ Pipe Doctor on his YouTube channel and having watched all of his videos I must say that he is one of the most honest contractors I have ever seen and his professionalism is incredible. It is so impressive that he always gets to the root of the problem quickly and always comes up with the very best solution on the spot. Anyone that hires his services must consider themselves lucky!

Mike and his crew are fantastic. Aside from exceptional work which is evident if you watch any of the YouTube clips, Mike’s knowledge is out of this world. Not only does he know his stuff, he also spent the time to make sure I had a solid background of the inner workings of the system. That’s very helpful to a homeowner!

While we live several states away, we watch the videos that Pipe Doctor releases on Youtube. Mikey is extremely responsive on their social media platforms, even to people that are not their direct customers. If Pipe Doctor ever branches out to my area, we will absolutely use them for all our HVAC and plumbing needs.

Pipe Doctor is definitely an A++ local business that is amazingly professional, more than reasonable in pricing, and super super fast. They do not skimp in on using the best product and the services that they provide is second to none. They finished my water heater install same day in the snow within 2 hrs from call, negotiating, delivery and removal. Will use in the future without a doubt. Pipe Doctor second to none!
