Lay plastic carpet runners in the areas that receive the most foot traffic. Carpet runners are made of a heavy material that will prevent the carpet from experiencing as much abuse. Lay the runners in busy areas, such as steps, in front of doors, hallways and the family room. The runners have spikes on their bottom sides that will help keep them in place.
Place decorative rugs in areas that sustain high amounts of traffic. The rugs will soften the blow of the damage caused by foot traffic and will delay the carpet wrinkling. Place the rugs in areas that see a lot of activity.
Use a carpet stretcher to keep your carpeting taut. Empty the furniture out of the room and use a power stretcher or knee kicker to stretch the carpeting. You will likely need to trim the excess carpeting that is created by stretching with a carpet cutting tool. Carpet installation companies can come to your home and perform this task for you, if you are uncomfortable doing it yourself.
