Carpet should be considered for restretching when it develops wrinkles or loose areas and the backing, seams, tack strip, and cushion remain serviceable.
The cause of the looseness should be identified first.
Moisture, delamination, damaged tack strip, or weak seams may require additional repair.
Furniture must be removed or repositioned so the carpet can be stretched across the room.
Restretching may involve trimming excess material and rebuilding transitions or seams.
