Since it was already snowing when I got my house parked and moved in, I decided to wait to do any kind of skirting till spring. And for a while my snow skirting worked. It piled up quickly and the snow the roof shed just added to it. For a while the base of my house was totally sealed.
But now we've been having a totally crazy winter and it's been really warm for here. I know the whole east coast has been getting hammered, but we've had almost no snow in 6ish weeks and it's been above freezing much of the time. And my skirting is melting out. I guess it's not too big a deal since it's warm anyway, and if it does ever snow again this winter, I can patch it up with the new snow. I guess if you are going to use snow as your skirting, I'd recommend living in an area that gets snow that particular year. We normally average 450 inches, but this winter it's not happening. Oh well, as long as it doesn't snow for all of May and June I'll be happy.
At the beginning of this month, this is what my skirting looked like.
Now it's looking like this and getting worse.
