Overwood (Hardwood Flooring)

Floor Detective® Claims and Conditions Guide

Summary

Overwood is a condition in which adjacent hardwood boards are not vertically flush at the finished surface, creating a measurable step or lip between board edges. The condition may originate from manufacturing thickness variation, profile engagement irregularity, substrate influence, incomplete seating during installation, environmental movement, or later in-service deformation. While the visible appearance may seem straightforward, overwood can develop through multiple mechanisms that produce similar edge-elevation patterns. Some products also include intentional bevels, hand-scraping, wire-brushing, or surface texture that may visually exaggerate normal edge variation. Solid and engineered hardwood flooring systems may respond differently because construction type influences profile engagement, compression behavior, and dimensional movement. In some cases, repeated traffic or rolling loads may create localized edge compression that resembles installation-related overwood. Proper evaluation requires distinguishing manufacturing, installation, substrate, environmental, and traffic-related mechanisms through measurement, distribution pattern, and flooring-system context. Minor elevation differences alone do not independently establish manufacturing defect or installation nonconformance without correlation to product tolerances and overall system behavior.
