"The work was excellent, however what was described and what was done differed. The maximum was described as the most extensive repairs. The repair entailed minimal digging and just the sealing of the main drain. It just 3.5 feet below the ground. One shrub was removed. They did not dig to the foyndation since they felt they found the issue. They did not reduce the price and that disturbed me since it was discussed."

"Worked with them to install french drain and sump in basement of home we recently purchased. There was an existing sump, but no french drain, and the location of the existing sump was inconvenient. Relocated sump to a corner where it was not in the way. Work was fast and efficient."
