After having to carry out many extensive and expensive renovations on our 130 yr old home, we were cautious about the extensive basement reno we had decided to undertake (underpinning, waterproofing etc). As soon as we met with Zibby we felt we could trust him and though he was not the cheapest quote, he was fair. Over the next months it became very clear we made the right decision. Zibby and his company are incredibly professional, respectful (punctual, clean), and will do whatever possible to deal appropriately with any "surprises" which might pop up (and in our old, often "renovated" downtown basement, many did). I unreservedly recommend Zibby and will only use AAA Waterproofing in the future. Thanks Zibby!
