Can humidity in subfloor cause overwood? Or is it installation issues?
Q: Can humidity in subfloor cause overwood? Or is it installation issues? I have several examples in my newly installed floor, plus several cracked boards. Some of the tongues at install were observed to be severely fractured, with multiple staples piled on top of each other. Also, the incorrect fasteners may have been used.
The contractor is blaming subfloor/basement humidity (floor is on first level above the basement), but I think it is a bad installation.
