After a recent rainfall we noticed that the drywall on the East side of our basement had water stains forming about half way up the wall. We did a quick search for some finished basement waterproofing and found First Waterproofing at the top of the list. We contacted them and explained the urgency of the situation (we have many high end electronics in our basement). They sent technicians over right away who inspected the problem and found a severe leak in our foundation. They came back the next day and by the time they had left, there were no more problems and my basement was saved. They also did a free inspection of the rest of the foundation which came up clean. Thanks for all the help Sergei, you and your team were life savers or basement savers I should say.
