The main reason why carpets begin to ripple is because of poor installation. The proper way to install and stretch carpet is with a power stretcher. A knee kicker is used when you are working in small areas. If you use a knee kicker to install carpet, eventually, the carpet will begin to ripple.
Our customer here in the Carefree needed the carpet stretched inside her bedroom. We have a 2 year warranty on our stretching labor, but the room must be vacant so we can stretch the carpet the right way. We also provide tile cleaning, upholstery cleaning and carpet cleaning services!
