So that weekend, I became a man on a mission: How to fix a double pane window without admitting defeat—or paying a $500 service call.
I cleaned the crack with alcohol, prayed, and injected epoxy into the hairline fracture. Then I pressed clear packing tape over it to level it while drying.
My wife walked by with coffee. “Did you fix it?” “Technically,” I said, “the crack is filled.” She pointed at the fog. “And that?” “Winter scenery,” I said.
I typed the search with trembling thumbs. The first video said, “If the seal is broken and there’s fog or a crack between the panes, you can’t just patch it.” My crack wasn’t between the panes—it was on the inside surface. That meant I could access it without removing the whole IGU (insulated glass unit). Hope flickered.
