Rugs get little traffic in 2 of 3 bedrooms. Very thick plush Carpet One type carpeting. Any suggestions?
Your carpeting is stretching which causes the wrinkles you described. Most often this is due to improper installation. Many installers just rough cut a piece of carpet, bring it in to the room, unroll it, trim it and use a tool to kick in the carpet under the baseboard and onto the tack strips. The proper way to do it is to use something called a power stretcher which stretches the carpet from one wall to the opposing wall. Go back to the people you bought it from and see if they can get the original installer to make it right. Most carpet stores send installers a lot of business and have a fair amount of influence over them. If they refuse or the installers refuse make sure you let them know your dissatisfaction and report them to the Better Business Bureau. Hopefully you won't have to pay for this yourself or take things that far.
