Need a legitimate waterproofing co. in westchester county, ny

A large corner of my basement rug gets soaked every time it rains. I have now noticed a bit of mold on the wall as a result, and am getting some little bugs on the floor as well. I am having a really hard time finding a TRUSTWORTHY waterproofing company that are experts in what they do, and that are not trying to pull one over on me. I would be so appreciative if someone could recommend a dependable, honest company. Thank you so much.
