Acclimating your flooring is very important. This allows the wood to “get used to” your home’s environment, i.e. temperature and humidity. Always unload your wood flooring into the house, ideally into the room where it will be laid. If you cannot unload it into the room where it will be laid, get it as close as possible, but it definitely must acclimate inside the house…not in the garage or an outside storage building.
Contrary to popular belief, acclimating is not a matter of time, but a matter of moisture. Ideally, you will want the moisture content of your wood to be within 3% +/- of the moisture content of the subfloor. Since most people don’t have a moisture meter laying around, we typically suggest 2 weeks. Try to plan for this very important step, because skipping the acclimation process can cause a lot of problems after installation.
