Brenden Smith and his helper (Shawn) came at the scheduled time on the installation day. They immediately began the preparation work (cutting holes, installing water lines, and PVC drain pipes) and setting up the toilet and sink in the previously selected locations. (Before the install work began, my wife and I concluded that the location for the toilet would be more advantageous, if it was turned 90 degrees and located against a different wall.) The plumbers agreed and work went along very well. The discussion during the entire install was cordial - between the two plumbers, and ourselves. I have waited five months before writing this review, because I wanted to be sure that there were no problems - and there have been no problems!!! We are very satisfied with the plumbers and the work they performed for us.
