"Robert was very responsive to my request for a water heater replacement. His pricing was competitive, and his crew was prompt and professional. The work was complete less than 24 hours after first contact. I recommend Robert Johnson Plumbing and plan to be a repeat customer, myself"

"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!"

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

"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."

"He was very knowledgeable and very friendly and his prices are very reasonable compared to other contractors and he did a great job installing wyn well tank I would definitely recommend him for any repairs"

"Excellent communication from Keith; outstanding service from Roger. Professional, timely, and reasonably priced. They came in under estimate on my boiler repair and advised that a second bit of work that had previously been discussed was not going to be necessary. I will definitely use them again and highly recommend them!"

"Angel was exceptional, professional, efficient, clean and responsive to every request, fixed numerous issues related to my toilets, noticed a flooring issue that we are now addressing and diagnosed a water heater issue that had been attributed falsely to a foundation issue saving us thousands. They are expensive compared to many but worth every penny we spent."

"Christian was very knowledgeable about our water heater and explained everything as he went along testing different issues that might be causing the problem. He was professional and gave me several helpful tips on upkeep of my Rinnai that 2 other companies that had serviced the unit over the years had not bothered to mention. i absolutely would recommend Walley to anyone needing HVAC work."

"We canâ t say enough good things about Walleyâ s from the moment we contacted them for a quote to the final review of the project! Every step of the way for our fairly complex mini-split heating/cooling installation was smooth. Their exceptional expertise, professionalism and customer service far exceeded our expectations and experience with numerous contractors over the years (building two houses and three additions). We want to give a shout-out to Spencer who was the mastermind behind our project. He went above and beyond. We highly recommend Walleyâ s for a good value and customer experience."

"Professional, friendly. Did the job and showed photos of the resulting flushed out debris from our on-demand water heater."
