Celio Group Incorporated Toronto

I hired Celio Group to remove an existing retaining wall and to build a new one in its place. The old retaining wall had come apart due to water issues. The contract we signed for the work had a clause that specifically stated that they were aware of the water issues with the old retaining wall and that they would design and build a wall that allow for the proper drainage of the water. Instead, the new wall has created a far worse water problem - now the water is draining into my basement, specifically because of the wall they designed and built. And, they are refusing to accept any responsibility for the issue even though they specifically agreed to properly address the issue in writing.
