    We had had our basement flood twice in a couple of years. Perma Dry found a poorly sealed crack in a foundation wall and repaired it beautifully. Even with huge rainstorms, we haven't had a drop of water. Highly recommended.

    We've had several very wet storm seasons since the installation three years ago, and the basement has remained bone dry, even while water covers large parts of our yard. We've doubled the usable space in our house.

    These folks were EXCELLENT. I mean "first class". Perma Dry delivered on their promises. I've had perfect and wonderful dryness. Nope, they didn't pay me to write this. I'm just a genuinely satisfied customer.
