Wilmot Hydro Mechanical works on the pumps that keep water moving in a house: well pumps, sump pumps and sewer grinder pumps. Google shows 5 stars from 10 ratings. A 2026 customer said the crew replaced a sewer grinder pump with a loaner pump on the very first day and was quick to install the new pump when the parts arrived. A 2026 reviewer recommended the company for anything that comes up with a water well and called Bob extremely honest. On Reddit in 2023, a North Stamford commenter wrote that Bob had just replaced their well pump and that they were very happy with the company. In 2024, a customer said Bob came within one hour on a Saturday when water seeped up through the floorboards, checked the sump pump and explained it was working fine. That 2024 customer said he traced the seepage to no perimeter wall or adequate draining and pointed out waterproofing fixes around the house. A 2024 customer whose sump pump failed after a storm said Bob recommended an improved sump pump system, the work was done promptly and on budget, and the new system was significantly quieter.

“I use Wilmot Hydromechanical and have been very happy with them. I’m in North Stamford and Bob just replaced my well pump.”
Wilmont was so helpful and got me the information that I needed right away. They always come through on time and do a wonderful job. I highly recommend them to anyone who needs their services.
these are the guys u want to talk to when anything comes up with ur water well. bob is super knowledgable and is extremely honest. doesnt try and sell you something you dont need and gives you the answer you need.
The crew worked really hard to get my sewer grinder pump replaced with a loaner pump on the very first day. They answered all my questions and were polite and professional at all times. A shout out to Rodney, Byron and Bob for being there every step of the way. When the parts and new pump arrived, they were quick to install it. Would highly recommend.
Bob is very knowledgable and patient. He was a tremendous resource for my mom and me recently as we navigated issues with a well and water issues. Highly recommend him.
Bob came and gave his recommendations since our new purchase had sump pumps that were not sealed and redesigned a new plan which included a back up battery even though we have a generator. The work was perfect, professional and exceeded our expectations. Thank you Bob and crew!
