Sean Ryan and his company, Century Masonry and Waterproofing, injected a few cracks in our basement using the polyurethane injection method in September 2013 to ensure we would not get water in our basement. They also blocked in one of our windows. From the first time I spoke with Sean I liked him - as it turns out, I was right! Before scheduling the work, he came to our house twice. He was very knowledgeable, professional and patient while explaining the method he uses. I told him we planned to sell our house the following year so the 5 year warranty which he provides and is transferable was something we were interested in. His recommendations with what needed to be done were right on.
Sean and his team were very knowledgable, great work, great...
