"The service team kept in touch regarding arrival time so I knew what to expect. The technician Jonathan worked quickly and efficiently. He had a water heater on the truck and was able to complete the work same day, unlike 2 other companies I got quotes from. While I was shocked at what water heaters cost these days, High 5's price was very competitive with the other bids."

"Brent was amazing. He not only cleaned the tankless water heater but also did a thorough checklist of the plumbing outlets, ordered, picked up & installed a faucet that we have long been waiting to replace. He was very fast, efficient, time & cost sensitive & professional. Thank you so much, Brent for a superior job!"

"We had the unfortunate incident of having a water heater break down in the winter. Unlike other places that were quick to diagnose that I just needed a new water heater just by talking to me over the phone, Jim Needham Plumbing sent in a professional. Tyson, the tech that was sent out, was by far the definition of professional. Iâ ve had techs come out that seemed professional but then just left more of a mess than when they came in. Tyson diagnosed the issues and not only gave me multiple scenarios I could choose from but made me comfortable in my decision. As soon as I made a decision and asked about next steps, he not only told me every step but accurately broke it down to how much time it would take. I was worried because if he missed his projected window I would not make my virtual meeting for work. He not only completed on time, he explained everything to my fiancée and she noted how meticulous and careful he was in our house and with the disposal of the old water heater plus the clean installation of the new one. In our next home project you bet we will be calling back to have them continue their level of experience and professionalism."

"If you’re looking for someone you can actually trust, Isaiah is the person to call. From the moment he arrived, it was obvious he genuinely cared about helping me make the right decision, not just making a sale. He took the time to educate me on my options for a whole home water filtration system and a tankless water heater, explaining the pros and cons of each without ever making me feel pressured. What impressed me most was how kind, honest, and knowledgeable he was throughout the entire process. He was the only contractor who took the time to truly educate me instead of just giving me a quote. I walked away feeling informed, cared for, and confident that I was making the best decision for my home. It’s rare to find someone who combines technical expertise with such genuine care for their customers. Isaiah is truly one of a kind, and I wouldn’t hesitate to recommend him to anyone looking for honest, client first service."

"The overall experience surpassed my expectations from the moment the communication began to the moment the job was completed. Kieth reached out shortly after I submitted my request for a quote. He was professional and polite throughout our entire conversation, and made sure to answer all my questions. The next morning Keith and his assistant arrived on time to temporarily fix the pipes so I can use the 2nd water heater in the meantime. Like Kieth, his assistant was very polite and professional. They both arrived the next morning on time to replace the broken unit. Kieth carefully brought the new heater to the basement and took the old one out for disposal. They worked efficiently to get the job done right and promptly; they left the area clean, and made sure there were no issues with the 2nd water heater. Plumbing Tree's price was very competitive compared to Lowes and Home Depot. For their quality of work, attention to detail, professionalism, politeness and the time they spent teaching me how to better care for my water heaters, I would highly recommend them to anyone without thinking it twice."

"Great team! They did the full furnace/AC/hot water replacement. They provided a range of options, with full disclosure of items I needed to do and those that could wait. The start to finish of this project felt right with this team."
