Tom - Mount Prospect, IL
Marlon was great. Had a leak in the ceiling of my kitchen from the upstairs bathroom. Opened up the drywall and an old copper pipe had corroded. Marlon came, took a look at the issue, and noticed the water lines were right on top of the drain pipes, and it had an old fitting they don't make anymore (and not in PVC). Marlon figured out a way to re-pipe the area and get everything working again. He did an awesome job.
