Customer Recommendations


Wet Basement Repair Wayne & Gloria Burns in Markham

The City Wide Group is a great company you can definitely rely on for this type of work. They came to our property and gave us a reasonable estimate for the work. Everything was done within the agreed upon time and they left the place very clean upon completion. Very professional. The only negative comment is that they still have to return to repair the interlocking stone that sunk after the job was completed. We recommend not to pay for the job completely until all final work has been completed. On the whole the job was professionally done.
