Tired of tripping over your wrinkled carpet? Thinking of selling your home? All carpets are subject to wrinkles forming. Anything from heavy traffic, to heavy furniture moving, to poor installation, to just plain old age can cause your carpets to "relax". Carpeting is made of materials with an elastic quality to maintain its tight apperance. Over time, the weight of people, or furiture can wear out this elasticity, causing wrinkles to appear.
Luckily, on most occasions, this "tightness" can be achieved once again.
Sometimes it happens, with older carpets, that the wrinkle problem is more than just re-stretching. The older the carpet or the more use it gets, it can break down, meaning the two layers of carpeting(fiber mat and backing mat) have become separated from one another. This is a severe problem usually resulting in the carpet neededing replaced because a stretch would be a very temporary stretch. Wrinkles will appear soon after any traffic or use of the carpet. .
