Carpet is only installed right by a power stretcher the first time. If someone comes to your door to install carpet ask if they use a power stretcher not just a knee kicker. If they do not have one send them packing. What most installers will not tell you is that if it is installed with just a knee kicker the mill will not guarantee the warranty on the carpet which can cause you problems later down the road. Feel free to pick up the phone and call myself Alan no job is to big or to small. My normal estimate fee is $75.00 depending on location and lowered if you like my estimate. Work performance and lowest estimate is guaranteed.
