If a carpet is not stretched tightly enough when fitted, it will not keep its form or stay in place” explains Sarah Jenkinson, Product Manager at Kingsmead Carpets. “It is always recommended that this is done when the carpet is initially laid. You can re-stretch old carpets in less than a day if you know how to do so, however, if the carpet is over 10 years old, the carpet fibres will become worn and damaged, making it necessary to replace them rather the re-stretch.
