Did a crummy job on my fathers garage. We followed their recommendations and it leaks worse than when we first called them. They keep blaming a clogged drain for the leak(it’s not clogged) to try and get out of honoring their warranty. Shady the way they sold it to me. The guy said it wouldn’t leak regardless of putting a drain in the center or not but he recommended it to remove standing water. Now he uses that as an excuse to ignore the fact that it never stopped leaking from day one. Won’t honor the warranty and won’t refund our money.
