Felipe confirmed the appointment this morning by texting he was on his way. On time and ready to do the annual maintenance on our tankless water heater. He completed the task and also educated me on the whole system. Five stars for a truly professional person and meeting a customer's expectation!

I HIGHLY RECOMMEND Plumbing Concepts for any and all plumbing needs. I had a new hot water heater and soft water system installed, and I am extremely pleased with their service and pricing. Fernando and his team were meticulous, skillful, and very professional. Fernando especially is a master at his craft, and he took the time to answer all of my questions in a very positive manner. Also, I am highly appreciative of Courtney for her tremendous help in arranging their professional service. Thank you Plumbing Concepts for your exceptional service, I am very, very grateful for your help.

I had such a great experience with their Plumbing Concept! Both Martin, the technician, and Lori in the office were super friendly and professional. Martin came to fix a leaking faucet and replacing the shower cartridge. Everything works perfectly now. I really appreciate their kindness and quality work — highly recommend!
