What Kansas City Homeowners Say

Pat Willis May 2026
★★★★★

Could not have asked for better service. Alisha was on top of handling our needs. She is so professional and friendly. Gave great information and answered all our questions. We would not hesitate asking for Jimmy again. We would recommend him for any project you have. Jimmy spent time locating the toilet we wanted. He was respectful of our home and cleaned up after completing the project. We highly recommend R&R Plumbing. Thank you Alisha and Jimmy. Kudos to them!!

Eric Underwood was very polite and friendly. He was extremely informative with every step he took to get the toy out of our drain and unclog our toilet! He was also super fast at diagnosing the issue and getting it fixed! I think he was only at our house 45 minutes to an hour! Very thankful for him!

Outstanding company to deal with. Great customer service. Alisha was very helpful in setting up an appointment. Jimmy was very thorough and helpful on the installation and repairs that needed to be done. Very helpful on suggestions for future work. Will definitely use R&R again
