I just had the guys from B-Dry come out to my house back in early February....they tell me it's gauranteed for life and fully transferable to the next owner should I decide to sell the house. They ain't cheap....I had four different places fixed where it was leaking (vertical cracks in poured walls), total bill was $2400.00 dollars (non-finished basement). They did it all from the inside. So far so good and we have had some pretty decent rains since the repairs were made. The two guys that came out seem to be just regular folk to me...I would use them again.
