"Our water heater burst over the weekend. We were desperate to get it replaced first thing Monday. Joe returned our call immediately, gave us a more than reasonable quote, was here close to noon, installed new equipment..voila HOT WATER again! Really efficient, nice guy, great job!! I highly recommend him!"

"Guy did a great job of diagnosing and repairing our State Hybrid Electric water heater. I would definitely recommend his work."

"Daigle were quick to reach out to quote me for the work we needed - replace a water heater and arrived early! Very personable, professional. However, pricing was an issue. They were way outside of what other plumbers charge for this service and way outside of what Angi's has listed as average project costs. They did have an opening for next day installation which would have been fantastic but I couldn't justify the additional $2400."

"David was very personable and professional. He diagnosed the issue quickly and replaced our water heater"

"We were able to hear running water but could not find the leak. We had multiple plumbers come out and they all said it was the supply line and that the leak could not be located and we would need to put in an entire new line. That would have required digging up a paved drive way and two retaining walls. When Steve came out he also determined that it was the supply line but he gave me the name of a company that could locate the leak for us. That company was great and once they marked where the leak was Steve came out and fixed the problem in a day without destroying our yard. He saved us about 15,000 dollars. He returned calls promptly, ahowed up on time and gave us accurate estimates. I will use Steve any time I need a plumber."

"Keith did a great job. Very professional, right on time, got the job done fast and done right at a very competitive price. Took the time after installation to show me the job and explain the features of the water heater, and also gave me information on how to properly maintain the unit and other services he offers. I would strongly recommend anyone consider Keith's services."

"Walley's sent a plumber out on a Friday to diagnose the problem, that being water collecting at the base of the water heater. The plumber indicated that the expansion tank, that had been installed the previous year by someone else, was not the proper one and would need to be replaced . He did not have the one I needed on the truck. There were also some issues concerning the way the existing one had been installed. Some pictures were taken of the tank, existing valves, and piping and Walley's sent another plumber out on Monday to install the tank. At some point the plumber had to leave the home to purchase some additional parts. I contacted Walley's after the service call was completed because I was concerned that I would be charged excessive labor time for the job, what with two service calls and additional time on the second call. Adrienne in the office discussed the matter with me, assured me that they would review all the paperwork, and work with me so that I was satisfied with the job and the bill.. They did just that--I have the correct expansion tank and adjustments were made to the labor charges so that I ultimately paid a reasonable amount for the replacement of the tank. The job turned out to be more than just routine but Walley's worked with me to make sure everything was fair and reasonable. Staff was always very courteous, friendly and helpful. I will call them again for my plumbing needs."

"Approaching a holiday weekend it was difficult to find a plumber to call back but that was serendipity because I ended up finding the right plumbers! Called in the morning, emailed in photos of my leaking water heater and got a new unit completely installed by two great guys by 3 pm! Couldn’t have asked for better people to work with. Thank you. ??"

"We would totally recommend Walley’s !!! Everyone was professional, friendly, nice and informative. We had no heat and a new born. They got us in ASAP and did a complete central air/heat with all the duct work as well as tankless hot water. They were efficient and continuously checked in on us before during and after the project was completed. Would use them again for another hvac project! Well worth the value !"
