My in-laws installed carpet in their home 30 years ago. It was high
quality and vacuumed regularly; it still looks good. However, they
have never had the carpet professionally cleaned in any way (either
steamed or shampooed). We may inherit this home one day. By then the
carpet will be 40 or more years old. Are their any health or
cleanliness problems we should be concerned about?


Yuck! Get rid of it no matter how good it looks. Open up all of the shades
and blinds in the house and turn on all of the lights to get a good look.
There are a tremendous amount of floor covering options today. Start
looking at them and decide what you might really want. Ask realtors what
they think in terms of resale value.
