Seam Peaking (Carpet)

Floor Detective® Claims and Conditions Guide

Summary

Seam peaking is an appearance condition seen as a raised or slightly elevated seam in stretch-in carpet installations. The condition develops when carpet is stretched after seam tape has bonded adjoining sections together, creating localized resistance at the seam compared to adjacent backing areas. This difference in movement may elevate the seam profile above the surrounding carpet surface and increase seam visibility under directional lighting. Shadowing across the raised seam may create visual contrast that resembles side match or shading conditions even when no true color variation exists. Seam peaking develops during installation mechanics and does not independently establish manufacturing defect, improper installation, or structural failure. See also Seam Overlap, Seam Overheating, and Carpet Problems for broader context.
