I have a crack on the side coming from window about 1.5 inches can I repair it myself. I'm only interested in stopping water from getting inside wall. Super glue etc.
If this is a side window. I would use Dicor Non-Sag Lap Sealant. You may want to drill a small hole at end of crack to help stop crack from continuing beyond where it has already gone. While doing the repair you may want to look at why crack started at window.
