I called Mark to renew a bathroom that had been problematic and in dire need of renovation. Mark went through the work and was very clear what needed to be done, explaining the reasons behind each step and the materials involved. The quote was very transparent and structured. He was very flexible when the work started. The team that installed the bathroom did so to a high quality. There was a slight setback towards the end of the fitting, but Mark addressed it immediately. I highly recommend Mark. He clearly has a lot of expertise and understands his profession deeply.
