He and Levi were very focused on doing the best job. Extremely thorough and personable. I highly recommend Core Mechanical."

"EXCELLENT! It was a somewhat emergency call because my walls were being damaged by the water, and Matt replied right away to my call trying to fit me in. He text back and said one of his guys, Ryan, was available and on his way! Ryan was great! Courteous, professional, punctual (and bonus - he unclogged the bathtub drain!). Thank you for saving the day!"

"He worked hard to try and get the old water heater working properly but age of the unit was to much for it to continue. We had him install a new unit and within an hour or more we had hot water. I would not hesitate to rehire if I were to need more work done. He is a hard worker and seems to be a person who is satisfied only when the job is done and working properly"

"He added a thermostatic mixing valve and expansion tank to my hot water heater. The solution looked good and functioned the way it was supposed to. He worked around my schedule and got the work done quickly."

"Wyatt was extremely knowledgeable, friendly, and easy to work with. His estimates were very reasonable compared to other quotes we received, and he took the time to explain our options clearly. He made honest, practical recommendations on plumbing fixtures that helped us avoid unnecessary costs while still getting quality results. We really appreciated his transparency and expertise. Travis arrived on time to fix our plumbing issues and install a water filtration system. He completed the work efficiently without rushing and was very careful with the fixtures. After installing the water filter, he clearly explained the next steps for proper usage and what to watch for to identify any potential issues. He encouraged us to reach out if anything came up and assured us he would come back promptly if needed. His attention to detail, professionalism, and willingness to help really stood out. Highly recommend this team for reliable, professional, and trustworthy plumbing services."
