We were referred to Saverio from Cornerstone Waterproofing by our architect and we are so happy that we were. From our first meeting with Saverio we knew that he was honest, reliable, professional, knowledgeable and competent. The scope of our project included underpinning the entire perimeter of our basement, lowering it from 6ft to 8ft ceilings and all the other things that are involved when you lower your basement (sump pump, waste injector, interior waterproofing, new drains, concrete floor and a few extras that we asked for). Brian and Kyle (Saverio's crew) are so friendly, easy to be around and hard working. These guys are truly wonderful people (even several of our neighbours mentioned how great they were). For 6 weeks these guys came to our house on time, never complained about being in a dark and dirty basement and were so kind to our boys, playing catch with them on their lunch break and chatting about baseball. Brian & Kyle even gave each of our boys baseball caps on their last day of work which they love and wear all the time. The project finished on time and on budget and was completely stress free for us. Since they finished we have called Saverio several times to ask him questions and he is always happy to help us. We highly recommend Cornerstone Waterproofing and would definitely use them again if we needed to. By the way our boys keep talking about a snowball fight that they are going to have with Brian & Kyle??? Thanks again for everything!
