I can honestly say that the work I had done with Connecticut Basement Systems to keep my basement dry was the best investment I've ever made. They installed a sump pump, drainage around the interior perimeter wall, and dug up a trench to install piping right through the middle of the basement where we had a problem. We have been dry ever since. The work was done quickly and efficiently and they took care to clean up after themselves (when you jackhammer in a basement, it creates quite a mess). I don't have one complaint at all. I also feel their cost was reasonable given the amount of work. Worth every penny. Highly recommended.
