I hired Denver Drains Service of Etobicoke to put in weeping tile system, my house was built 1910 and no weeping system existed. The owner Lloyd N. came out to do the estimate and I agree to the work to be done. Denver Drains, dig up between my house and my neighbor's house (theirs was dry before this). In the summer of 2009 after the work had been done, the weather wasn't so great, there were many rain storms in Toronto - results neighbor’s house had a steady stream of rainwater down the side Denver Drains did, their basement is now wet. My house, mid corner, house extension was wet. Called Denver Drain, interior mid corner they did a bandage job as well as put 6 inch piece over my neighbor’s ground line (which was installed backwards -the revise side on the outside). For the work I had paid them to do on the extension of the house and corner - they have not done anything, I discovered after the corner mid section had only a 22 inch piece of membrane - no water proofing liquid rubber. The extension of my house buckled, from Denver Drains adding additional gravel in the extension,this was to cover up the work - they had never done, as well as changing the grade to run into my neighbor's house, this resulted in a mud slide in basement. Denver drains did not return my calls. Hired a contractor to repair my house and my neighbors. When they excavated the extension and mid corner I took pictures of the cover up that Denver Drains did but they sure charge me for the work that was never done.
