Weโre very pleased with the recent plumbing work at our home, where three tunnels were dug under the foundation to replace our entire cast iron sewer system with PVC pipe. The plumbers also replaced the wax ring in our hall bathroom, and the photos and videos provided of the work were excellent. However, the third-party tunneling crew left trash behind, which they cleaned up after I pointed it out, and the plumbers left a blanket and a mess of dirt and hard substances on the floor, unnoticed until after payment. We appreciate the quality of the work but wish both teams had been more conscientious about cleanup. Four stars.
