What it is
A new timber floor with a dip, showing a gap under a straight edge.
Why it matters
Out-of-flat floors look wavy, can squeak and affect how furniture sits.
How we check it
We put a straight edge and level on floors and measure any gap.
The fix
Rectify the subfloor and floor so it's within tolerance.
How common it is
We measure floors at handover, not just look at them.
