Amongst the great deals that I have been finding,I sometimes find properties that have water seeping into the basement, and the cement walls seems to cave in a little bit. The past owners, or agents nail either sheetrock or wooden boards to cover up the wall. Sometimes I see this to an extreme where the whole lower length of the wall is caving in, and in some properties its not as bad.

I believe this is due to the water seeping in from the soil, and ineffective gutters and something to do with the sump pump?

My main question is what jobs are required to fix the wall and prevent water from seeping in. And what is the min and max amount that something like this could cost.

Thanks in advance!
