Low(er) Odds of Wet Basement
Older may not be better when it comes to furnaces, roofs, and major appliances.
However, if there’s any question about whether a home’s basement is wet, old is very good.
Because carpeting that repeatedly gets wet and dries out becomes moldy, discolored, and generally starts to deteriorate.
Ditto for any carpet pad underneath (those actually disintegrate when repeatedly soaked).
Ergo, old carpeting that has none of those attributes likely means a dry basement ” or at least basement room . . .
P.S.: Similar logic applies to carpeting over hardwood floors.
Namely, the older the carpeting, the better condition the underlying hardwood floors are in (usually).
