Would appreciate any advice.
Had an extension completed over a year ago. As part of that, i had wooden flooring put in.
Soild Oak 18mm. It was fitted xmas 2019.
I have noticed that its come off the floor in this one area. Almost like its expanded and lifted up on the joint. Seems to be a few pieces affected by this lifting. Its quite high now and becoming a bit of a hazard.
Can anyone shed any light on why this is happening now over 12 months later and what i can do about it. I do have some spare pieces of flooring, but they are tongue and groove fit so not sure how to go about replacing or fixing the problem.
