Had these guys in to inspect a 'mystery' pipe that was the suspected source of infrequent basement flooding. While the team was extremely professional, and courtious, they were unable to determine the role of this pipe in our house, and were unable to tell us what might be the cause of the minor floods we experienced during heavy rain. A camera was sent down multiple drains in an attempt to determine the issue. This work ended up costing us ~$270, but unfortunately didn't help the team (or us) understand the problem.
The proposal that was written, was to jackhammer a 6ft section of our basement floor to 'inspect' the system and determine what repairs would be needed from that point forward. This would have cost us ~$1700, and would have been mostly exploratory.
In getting a second opinion, the problem was IMMEDIATELY identified as being a broken sump pump (~$500 installed). Had I contacted this other company first, I could have saved the $270 we spent on the camera work.
I can't believe that a company with this many positive reviews and this much experience failed to inspect (or even ask about) a sump pump, which resides right next to where they were standing. Further, in speaking with a Drain Works representative after initially posting this review, I'm now further convinced in my decision to work with another organization.
