Davies Contracting completed new drainage around my Victoria home. Had the following problems. 1) Backflow valve was installed backwards - major flood. 2) PVC pipe does not align to downspouts. 3) Driveway grate is not plumb nor square. 4) Cement lines were done freehand and not with a board. $40,000 damage to basement. One star is too many. Avoid this contractor at all costs.
