I know we have some knowledgeable folks here, and was hoping to take advantage of the collective wisdom. I've just finished building a cottage and am really struggling with the flooring. It's close to Lake Michigan, and the relative humidity is always 50% - 80%. We keep the place open when we are there and closed up when we aren't. We don't have AC, and keep the heat about 40F during the winter. The floors are 3/4" maple, and within two months of installation started cupping and even buckling in some places. They are a mess. My neighbors all have solid wood flooring, no AC or dehumidifiers, and have not had a single problem. I've got a dehumidifier in there now, but am looking for a long-term solution. I was thinking now that they have swollen up, if I go back and cut additional expansion gaps along the edges, the buckling would likely settle down. Thanks in advance for any suggestions.
