Carpet claims can arise as a result of unexpected performance or installation issues that become evident during, or any time after installation. Some of the most common carpet claims involve appearance change, poor installation, visible seams, unraveling, cornrowing, matting, crushing, spots and stains, delamination, buckling, maintenance issues, side match, footprints, shading, lines, odors, pet issues, pooling, watermarking, roll crush, snags, vacuum cleaner issues, visible defects, miss-specification and many more. Certified Floor Covering inspectors go through specialized training giving them advanced knowledge related to manufacturing, properties of fibers, proper maintenance, installation, subfloor prep, as well as understanding problems, causes, cures, and warranties related to carpet claims.
