We had a prefinished hardwood floor installed in our family room (approx. 20'x20') and along the nailed edge of approx. 1-2 dozen boards there are "bubbles" which we noticed when they were catching on Swiffer duster. Installer was perplexed so we called the distributor who came out and said installer did not have nail gun set properly before nailing and that the nails are at the wrong angle which is causing this "bubbling". Here are the 2 options installer offered to "fix" the issue:
1. Sand and refinish entire floor. Not really a viable option to us since product has 35yr warranty on the finish. Why would I remove it?
2. Rip out each affected board and glue a new board in its place. My concern with this option is how will it affect the expansion and contraction of the floor? We live in New England so there is a great variation in temp and humidity throughout the year. Does this sound like a reliable fix to our problem or will it just create future issues of buckling when the floor tries to expand against the glued boards?
Thank you all for your advice!
