Why should hardwood flooring material be delivered to the job-site several days before installation?

Delivering hardwood flooring material to the job site several days before installation is essential for allowing the wood to adjust its moisture content. Wood is a natural material that is highly susceptible to changes in moisture levels. When hardwood is manufactured, it may have a different moisture content compared to the environment it will be installed in. If the hardwood is immediately installed without this acclimation period, it may expand or contract due to moisture changes after installation, leading to issues such as gaps, buckling, or warping in the flooring.

By leaving the hardwood flooring in the installation environment for a few days, the material can reach equilibrium with the room's temperature and humidity levels. This process helps ensure that the wood maintains its intended appearance and structural integrity once installed, resulting in a more durable and aesthetically pleasing floor.
