If your carpet is not installed correctly it could shorten the life-span significantly. Professional carpet installers (almost always) use a power-stretcher to stretch the carpet tight from wall to wall. This all-important “stretch” prevents wrinkles from developing during the life-span of your carpet. Another tool, the carpet knee-kicker is to be used in addition to the power stretcher. The knee-kicker is a hand held tool with a rubber pad on one end, the installer uses his knee to move the carpet into place. It looks like it hurts the knee to use this tool, and it does! If the installer just uses a knee kicker, your carpet may not be stretched in tight enough. Sometimes, in a very small room (10 x 10 or less) , a knee-kicker may be sufficient to get enough stretch. Before you hire a carpet installer, ask if a power-stretcher is used. If not, you may want to look for another carpet installer. Do you have carpet installer questions? Post your questions here!
