Algae on Vinyl Siding and Crawlspace Moisture
I’ve read a whole bunch of old posts and articles, but, like so many other times, I still need some expert analysis and help.
I have a small cottage in the Catskill Mountains of NY, with some fiberglass batting between the 2×4 studs and some mineral wool between the studs and above the ceiling (on the floor of very low attic).
When I got the place, one external wall had some green mold/mildew/algae growing on the vinyl siding. I removed some pieces and the wood underneath (which was a T-111 type siding) was dry and without any evidence of mold.
Lately I think I smell a mildew smell and have a light covering of dusty stuff that I’m worried is mold. No other visible signs of mold or dampness.
The 2×6 flooring framing sits only several inches above dirt. No vapor (or any other type of) barrier.
The perimeter of the house, which the framing sits on, appears to a several inch wide concrete footing (that is, several inches wide and running the entire perimeter). The footing comes up several inches above the dirt line and has the framing members sitting directly on top of it.
There’s no room for even a skinny guy to crawl underneath.
I’m attaching some pictures.
What would you all do?
