help! gaps widening in newly installed wood floors
We could really use some suggestions!We recently splurged on four inch wide, long plank red oak floors for the first floor of our house from a mill in New Hampshire. For the second and third floor of our house, we went with narrow plank select red oak supplied by our general contractor. Both woods acclimated to our house for ten days with the heat on. A week after installation, the wood from our contractor is looking great, but the wood on the first floor is showing widening gaps. We are really stressed out because we can't imagine a fix for this. Our contractor won't remedy the issue because he did not buy the wood, and the supplier of the wood is a mill that didn't do the install. Any suggestions about what we can do to would be very helpful!
Thanks so much!
