“M.P. Kelly Inc. has been taking care of all the plumbing needs at my house, in my office and at all of my rentals for years. They do such a good job and I trust them so much - they have a spare key to all of my places.”
“I have used M.P. Kelly for years, but it wasn’t until I opened my own business that I really appreciated how fantastic they are. Mike is always there for me - he is wonderful to work with. I recommend them to everyone!”
“I have worked with M.P. Kelly Plumbing not only for my place of employment, but also in my home. They are highly qualified and have always gone beyond my expectations - from installing new sinks, water heaters and sump pumps. They are always clean and respectful of your property. Every employee interaction has been more than pleasant - they are a great group of people.”
“They are prompt, friendly, and do great work. When I needed a pump replaced I called them at 9:30 and the work was done by 12:30, I can’t ask for better service than that.”
“My husband and I have used M.P. Kelly Inc for all of our plumbing needs for over 15 years. They are fast, efficient and always friendly. They even did two complete bathroom remodels - we just love these guys.”
“Mike did a professional and awesome job. We had an emergency with my moms’ basement flooding and Mike was able to come over within half an hour of calling. The installation work he did for the sump pump was clean and done with care. Fantastic work. Will definitely be doing business with him again. I’d recommend him to anyone needing a plumber.”
