I hired Dr. Rooter to replace the concrete in my basement. This is the worst contracting experience I have ever had in my life.
The contract was to remove existing concrete, pour gravel, and then pour new concrete.
The old concrete removal went smoothly. The disaster happened on new concrete day.
The boss, <name redacted>, dropped off equipment for the crew and then left. The equipment he provided included a concrete slide for getting the concrete through the basement window, into the basement.
The crew consisted of 4 young men who didn't speak English. They ignored the contractual agreement to place gravel down before the concrete. Instead, they poured the concrete directly onto the dirt under my house. The threw the concrete through the basement window using a wheelbarrow without using the slide and destroyed my freshly parged and painted walls and pillars as the concrete splashed everywhere and made a huge mess. Worst of all, they did not level the concrete. The floor is now so uneven, it's practically impossible to cover. In short, an unbelievable disaster. I expected a professional job and instead I now have a liability--concrete directly on dirt, horribly uneven, under my house. The value of my property has gone down as a result.
The root cause was lack of supervision. The supervisor dropped off the slide in the morning and then disappeared for the entire day while a crew of young inexperienced amateurs destroyed my basement.
NEVER hire Dr. Rooter for basement concrete.
