No, the manufactures have addressed this issue – it is no longer a concern. At Apex we do an inspection step to discuss any and all issues before we begin. One common issue is the tacking strips are not secure and needing anchoring. Sometimes this can create the illusion of shrinking because when your carpeting was first installed it was stretched into place and held there by the tacking strips. When this “connection” to the tacking strip fails the carpet relaxes back to its pre-stretched form.
