I am currently looking into buying a house built in the early 60’s and our private inspector noticed this crack in our foundation. The crack is underneath one of the basement windows and appears to run from one side of the window to the other. He was not very concerned about it and believes that a professional repair/waterproofing will be enough to fix the problem. We noticed that the downspouts in the back yard do not have extensions, so they are releasing water quite close to the foundation. This was planned to be fixed (regrading, downspout extensions) as soon as possible after closing.
No other issues were noticed with the inspection (such as bowing, doors not closing properly, etc). We were quoted about $450 for a waterproofing/repair from a reputable local crack repair company, which seems reasonable to me.
Does my inspectors opinion seem reasonable in this case? Or does this appear to need additional oversight or corrective action?
