Crack-X
I think it is $595.00 per crack (floor to ceiling) and they guarantee it for 10 years. I had it done to my last house in 2005 and then we got all that heavy rain and not one drop of water came through. To watch them you could probably do it yourself but it would cost you a couple of hundred in materials I would think.....
The waranty is transferrable.....
