Anybody ever seen, basically icicles streaking down vinyl siding, coming out of the drain holes?
I went out to have a look at the vents today to see how they're holding up and discovered it. I've never seen that before
I'm kinda puzzled by it. It's on the "wet" side of the house, ie: where 90% of the plumbing fixtures are. My best guess is vapour from the bathroom and kitchen sink window escaping through to the cold side and started to drain on those warm couple of days, then froze again as the deep freeze re-visited.
No vapor barrier is perfect, but I'm a bit surprised by the discovery. If my guess, is what's going on.
