I'm seriously thinking about covering the T1-11 siding of our rancher with a
synthetic stacked-stone. I haven't gotten an estimate yet, having just
looked more closely at the builders show. My question is, "is there a down
side to this kind of siding"? Oh ya, "Is there any other enhancement that I
should consider"?

I plan to have the siding and fascia covered with aluminum at the same time.
I had the old window replace several years ago with low-E therma-pane.

TIA,
Chuck
