When your carpet was initially installed, it was stretched and attached to tacking strips. Over time, especially in areas that receive high traffic, the carpet may need to be stretched again. This simply means that the carpet needs to be pulled as tightly as possible back over the tacking strips.
Signs that your carpet needs to be stretched include ripples or lumpy spots in the carpet and the edges of the carpet appearing to be pulled up instead of tucked down. If you are experiencing any of these signs, you should get your carpet stretched as soon as possible.
The ripples or lumps in the carpet can pose as a safety hazard. A floor should be smooth and the ripples can cause a person to trip and fall.
Floors that are neglected to be stretched can wear unevenly. This can diminish the potential life span of your carpeting.
