Basement Floor Warping
A wood floor that is warping or discolored is almost always a sign of excess moisture either below the floor or even in the air of the basement. Wood absorbs moisture and over time as it expands and contracts due to the changing temperature and humidity levels in a basement, the floor will begin to warp. Usually you have no choice at this point but to replace it, however steps must be taken to analyze and solve the humidity issues underlying the cause of the warping.
To support the longevity of a wood floor in your basement, humidity and temperature levels must be stabilized as much as possible typically through use of Dehumidification Systems or thermostat controlled space heating solutions or both.
