My walls look like a disaster waiting to happen. The cracks in the walls expand and contract depending on what time of year it is. I have come to the conclusion that I will have to install some type of drain system. The walls are of a block construction, and there is no sump pump. I have not seen any significant movement in the walls that I think would require any structual support.
Now to the problem. I have had a number of different contractors over with many different stories. Prices have been from $4,000 to $13,000. One wants to excavate and another says that it is not necessary. I even have two different contractors who sell the same systems through the same franchise giving two different stories.
I have seen a lot of different systems and I am not sure which system is the best to use. I want a good warranty that means what it says.
Please help. I need some advice.
