Has anyone ever had basement wall supports built for bowed basement walls? Doing due diligence on a house and it came up that the walls are bowed and leaked...it is fixable but I have no idea how much...has anyone either had it done or is a contractor that can give me a rough estimate? trying to decide if we should do it after purchasing the house, or tell the sellers it must be fixed and added into price of the house (in order to finance it.) thanks!
