Ghada Sharkawy in Toronto

Cornerstone is truly exceptional in both the quality of their workmanship & professionalism. After an enormous amount of research & meetings with almost a dozen waterproofing companies, it became clear that Cornerstone had more exacting standards of workmanship than ANY of the other contractors we had met with, including those which are considered to be the best in the city. Saverio's quote was either slightly lower or significantly lower than that of the other contractors, while his waterproofing solution was BY FAR the most comprehensive of any that had been proposed to us, including those from the few waterproofing companies that are considered the best in the city. No other contractor was prepared to do the work as comprehensively as Saverio did because, we were told, it would have been too labour intensive & costly. Saverio is very picky about the quality of his work, which is exactly what you want from a waterproofing contractor. His work was absolutely excellent, which has bought us complete peace of mind that our waterproofing issues have been fully addressed. The friendliness & professionalism of both Saverio & his crew also made them so easy to work with & a complete pleasure to deal with. I am beyond grateful that we discovered Cornerstone & have already recommended them to all my friends, relatives & colleagues at work for any waterproofing issue they may have. Huge thanks to you, Saverio.
