B.M.
D. I to have had this problem at my home now. At purchase the inpection company overlooked the leaking water in the corner or it hadn't rained?
Anyhow we called just a handyman, yes he did remove some panel from the wall not much. Then repaired the leak with things from Home Depot it was a foundation crack. I understand money is a factor but something has to be done before other problems get worst.
If you should need a great Handyman Please call for the number and references. ###-###-####
