Should you fix a bad foundation crack yourself or call a pro? Here is what happened to me
I found a hairline crack in my basement wall last spring in my 1980s house near Portland. I watched some YouTube videos and bought a $40 epoxy injection kit from the hardware store. After I injected it and let it dry for 48 hours, the crack spread another 3 inches down the wall during a rainstorm. Then I called a foundation guy who said my patch job actually made it worse by trapping water inside. Now I am out the $40 and looking at a $1,200 repair bill. Did I mess up by trying to do this myself, or has anyone else had luck with DIY foundation fixes?
