sewage was backing up and "water" was coming up the drains in the basement. Somebody came (with a camera) and suggested the problem was at the base of the stack and we should dig there and replace part of the stack, etc. $3,000. Strange thing was that the water was backing up downstream from the stack!! Somebody else snaked it and we got partial results, but needed a permanent solution. Friends recommended Drainworks. Mike Dunn and his team came and took the time to really investigate what was going on. They guide me through their investigation, showed me what the problem was on the camera (tree roots) and where (outside the house!). He gave me an estimate, and after I tried to get other estimates, I called him and contracted the work. Mike and his team were very carefull when they got in the house, protecting floors, & doors when they put equipment inside the house. They also helped me with the application for the city grant, told me when to call the city inspector ... unbelievable. The work was done as agreed, when it was agreed, and it costed me what they told me it was going to cost me. Excellent service
