What is one reason moisture levels should be checked prior to flooring installation?

Moisture levels should be checked prior to flooring installation primarily to prevent mold growth. High moisture content in the subfloor or the surrounding environment can create an ideal condition for mold and mildew to develop. If flooring is installed over a damp or moist surface, it can lead to serious problems, including the deterioration of the flooring material itself, unpleasant odors, and health concerns for occupants due to mold spores in the air. Ensuring that moisture levels are within acceptable ranges helps to create a stable foundation for the flooring and ensures a longer lifespan and better performance of the installed materials.

While assessing labor costs, evaluating aesthetic choices, and determining subfloor conditions are important aspects of flooring installation as well, they do not directly address the urgency and implications of controlling moisture levels for preventing mold growth, which can have detrimental effects on both the new flooring and the health of individuals in the space.
