"We contracted with High Five Plumbing to purchase and install a 40 gallon water heater to replace a 21-year-old unit. Our experience with the company was terrific. Members of the office staff were cordial, helpful, and professional, providing options and information, following-up on appointments, etc. Caleb, who installed the water heater, is a real pro and a good guy who answered all our questions and provided a thorough explanation of the various services offered by High Five. He is a credit to his company. We didn't have a plumber on our contacts list. We do now. Cliff Foster, Denver"

"I had a terrific experience with the team at Heart HVAC & Plumbing. I needed my tankless water heater to be flushed and a faucet to be fixed. I must have stumbled across an old coupon that was missing some verbiage as there was some confusion from the techs. They handled the situation with class and agreed to honor the dated offer. The techs were professional and did great work. I would not hesitate to hire Heart again."

"EZ Repair does it all…from plumbing, electrical, HVAC and handyman tasks…It’s really a one stop operation. The difference between this company and others is that when you call EZ Repair they are out to your home or business the same day if that is your request. Best of all they are fairly priced. I think everyone who works at this company must enjoy what they do because it was obvious to me. Their customer service was excellent! I would highly recommend using their services."

"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."

"Christi Gaias was very professional and provided me all the information to make a decision about replacing my current water heaters with a tankless water heater. He was very knowledgeable and understanding of the specific needs I have for my home. Thank You Christi"

"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."
