What is the appropriate time period for allowing the wood to acclimate to the house?
Hardwood flooring is typically kiln dried between 6% & 9% moisture content. In a dry home environment it is desirable to allow flooring materials to acclimate for several days before installation. Where floors are being added to existing homes one can allow as long a time as is practical for acclimation. Ideal conditions in a new construction or remodel situation would provide that all wet work has been completed for three or four days. Subfloors should be scraped and cleaned and the environment should have permanent heat. Production schedules may not allow for this scenario but an increased probability of cracks due to absorption of site moisture is likely. We also check the moisture content of existing wood or subfloor and the new wood to make sure they are within 2-3% of each other.
