Seam Overheating (Carpet)

Floor Detective® Claims and Conditions Guide

Summary

Seam overheating is an installation-origin condition that occurs when excessive heat is applied during hot-melt seam construction, resulting in localized distortion directly above the seam line. When heat exceeds the tolerance of the carpet backing, seam tape, or pile yarns, the seam area may become recessed, compressed, hardened, or permanently altered in texture and appearance. The affected zone is typically confined to a width consistent with the seam tape beneath the backing and commonly remains visible under multiple lighting angles. Seam overheating develops during installation and does not result from normal traffic, maintenance, or environmental exposure. See also Seam Peaking, Dark or Light Line at the Seam, and Carpet Problems for broader context.
