“Hey, check out McMahon's Water Services out of Alfred. I can vouch for Ed's work, he's helped me in a pinch on more than one occasion”
My well pump failed. I was introduced to McMahon's Water Services by my trusted builder. I really can't say enough good things about this company. EJ did the work for me. He was professional and pleasant to speak with and explained things well. He replaced my submersible well pump and I also had him replace the tank as it was on its last legs. Everyone I spoke with at this company was fantastic. Kathy answered when I first called and she was just so friendly and proficient that I felt in good hands immediately. Communication was great all throughout. McMahons will be my "go-to" water/well company from here on out. Thank you to the whole team!
Always Great service from Ed, Cathy and the rest of the crew! We appreciate all you have done over the years for us. 7/19/26- Got in the shower on Sunday morning and shocked to find out that there was no water coming out of the shower head! Called McMahon Water and Caleb was at the house by noon. He diagnosed the problem and had us up and running in a couple of hours. So grateful for them showing up on a Sunday Afternoon and getting the job done so quickly! Thank you!
Excellent customer service! They answer the phone, send out their folks promptly. They are professional, knowledgeable, and extremely courteous. Thanks so much, Chad, for installing our well pump so quickly!
This is a great company to work with. Installed a new water filtration system without a hitch. Nate and Bo truly professional and all went smooth. Great customer service. Thank you!!
McMahon's Water Services is a top notch company in every way! We needed a new well point installed in a tiny closet under a stairway in our basement. McMahon's Water Services was highly recommended by a drilling company with whom we had worked and so we contacted McMahon's. They came right out to our camp, assessed the situation, devised a plan, explained it clearly to us, gave us an estimate and scheduled the installation. They contacted us a couple of days before the installation and again on the day of and showed up exactly when they said they would. Chad and Sean went right to work and installed the new well point and reconfigured the pump room to conveniently accommodate the new placement of the hot water tank. They clearly were the ideal team for the job. They were personable and efficient, communicated clearly and charged a very fair price consistent with their estimate. And now we have plenty of water pressure and plenty of water! What a pleasure to deal with these knowledgeable young men. They are true professionals who obviously know their trade and take pride in their work. Many thank to you, Chad and Sean!
