I had a solid oak floor laid 6 weeks ago. In the last two weeks it has buckled to a height of 3 inches! Had the installer back and he reckons there is damp underneath the house. His damp meter read 18 in some places but only 9 in others. He left a 5mm expansion gap when he did the job (with glue).
Went to my neighbours house where they have oak flooring with no problems (a bit of cupping but still looks lovely). Damp reading 20 in some places, 7 in others, so roughly the same. Their installer left 12mm gap and used nails.
My installer says that even if they'd left 10mm or 12mm the boards still would not have had enough space to expand as the buckling is so high. Is this true?
