I was up early this morning and decided I should stay up and actually be productive, which meant working on the shelves I’m putting up in the garage. Now, I get up early when I have to go to work, but on my days off, I like to sleep in, which means I usually don’t start working on stuff in the garage until the evening on days I work, and almost never before noon on my days off (what can I say, I like my sleep!). So I was surprised to see sunlight coming in through the wall I uncovered earlier this week:
I think I found the problem! There appears to be no flashing whatsoever on this part of the house. I mean, the J-channels are there to direct water away, but there’s nothing there to stop the creepy-crawlies from getting to the wall once they get under the siding. Also, there appears to be a redundant J…
Think it would be possible to take off the bottom layer or so of siding, slip some metal sheathing in along the concrete of the porch (leaving it tall enough so it extends, oh, say 6″ above the level of the porch, hidden behind the siding, and a few inches below the concrete footing of the garage) so nothing else tries to destroy the new wall I plan on framing up? Here’s a sketch again showing the level of the porch in relation to the garage wall:
Right now the plan is: remove the bottom few layers of siding to expose the rotten portion of wall from the outside, brace the ceiling and chop out the offending portion of wall, spray foam into any spaces I find under the porch, slide some metal sheathing down into the gap between the porch and garage, reframe the wall using green plywood (I hate OSB). Oh, and spray foam into the entrance holes under the porch as well- don’t want any more critters trying to call it home!
