My guess is it was not stretched (kicked) in very well.

Over the last few years the carpet has developed substantial wrinkles.


My last new house did the same after a few years. The cure was to
stretch it again and trim it. You can rent a "knee kicker" or ones
with poles that will span the room (caution with that one - you can
tear the carpet)

Can anything be done to get it to contract? I've already priced having a
reputable company come and trim it, and it's more than I feel like
spending to cure the problem.

Nothing I've ever seen. How old is this carpet?
