At this house in Mesa, they had bumpy, wrinkled carpet that was in need of repair. They had a carpet ripple that went all the way down the middle of the room. If left untreated, the carpet will wear unevenly and become damaged near the wrinkle. When carpet in a room is stretched with a power stretcher, it should be free of furniture. Carpet wrinkles not only do not look good, they also pose a tripping hazard.
