Carpet pattern elongation or pattern “mismatch.” With integrated pattern carpets this mismatch is referred to as pattern elongation. Pattern elongation is caused by the patterns on one side of the carpets seam being slightly longer than on the other side.
Pattern Elongation Along Seam of Carpet
With pattern elongation, one panel of the carpet may have 30 patterns in 15′ – 0″ section, while along the other edge you have 30 patterns in 14′ 10″ section. This pattern mismatch or elongation, results in a pattern that appears to grow or elongate. A pattern mismatch to this degree is usually workable but can take additional installation time to make a match.
Often with pattern matching problems we find that the carpet was installed by a carpet installer that specializes in residential work. A carpet installer that may be a genius when it comes to cut pile carpet, may not be that familiar with commercial carpet installation and working with patterned carpets.
Carpet manufacturers do not guarantee that a pattern will match. In most situations a pattern match claim will be declined unless it is not only severe, but the manufacturer had instructed the installer or dealer to go ahead with the installation, and they would stand behind it. While some seams are correctable by a knowledgeable installer not all seams are. When a patterned carpet is involved, a wise end user will make sure that the installer has the experience to work with these styles.
