Telegraphing (Carpet)

Floor Detective® Claims and Conditions Guide

Summary

Telegraphing is an appearance condition in which underlying substrate features become visible through the carpet surface. The condition develops when the carpet and cushion conform to substrate irregularities such as joints, cracks, seams, patch transitions, or surface-profile variations beneath the installation. Telegraphing follows the layout of the substrate and typically remains consistent regardless of viewing direction or lighting angle. The condition primarily affects appearance uniformity and does not independently indicate fiber damage, backing failure, or loss of structural integrity. See also Buckling / Wrinkling, Shading / Footprints / Vacuum Marks, and Carpet Problems for broader context.
