We had three quotes on a spring flooding issue last year. and backwater valve installation. Two companies were pushing extensive (and as it turned out, unnecessary) work at considerable cost. Santos came in and immediately suggested a very practical, affordable, and permanent solution. We also had them install a backwater valve at the same time. All work was was done with minimal mess, despite tough digging in North York soil, and thorough cleanup. In addition, Santos was the only company that mentioned the City of Toronto rebate program for backwater valve - and they did the paperwork necessary for us to apply. Highly recommend Santos Water and Drain.
