I have had Mark and the Rightmark team do work for me on multiple occasions. (Plumbing for basement finish, dishwasher, sink, disposal installations, burst pipe repairs & more). Finding a trustworthy repair service (plumbing, appliance, car) is always a concern and when I find someone that fits the bill, I stick with them. Rightmark has never disappointed.
The work has been good, never had to have any re-dos. The cost has been reasonable and I'm confident that, if anything did come up, they'd stand behind their work. Haven't had to test that yet.
Highly recommend them
