Homeowners often notice that their carpet has developed wrinkles and has stretched since installation. Stretching in carpet occurs for many reasons, from carpet materials to improper installation.MaterialsSome carpet materials are more resilient than others. Wool has the most resilience and can be stretched over and over and still bounce back to retain its original shape. Olefin, a lightweight carpet material, is one of the least resilient materials, according to “The Carpet Buyer’s Handbook.”ConstructionCarpets are manufactured in different ways for aesthetic purposes as well as durability.
