I am very satisfied with the work done. KBI arrived early each morning and worked non-stop until the job was done. Keith took the time to explain the various job activities (sewer line replacement, internal and external drain tile system clean out, 130 foot pipe system to redirect gutter/sump pump water to back of yard) and how all worked together to fix water seepage through my basement cement floor. I am confident work was done with high quality. Only negative was price -- higher than expected.
