Most ground floors in Burton Latimer are solid, which makes flooring here a preparation exercise, with one local complication worth knowing about.
The two ordinary questions on a solid floor are flatness and moisture. Most slabs need levelling before a hard covering goes down, because a floor out by a few millimetres over a couple of metres looks fine to the eye and shows badly in large format tile or engineered board. And we test for moisture rather than trusting the look of a slab, because one can appear perfectly dry and still be wet enough to lift an adhesive within a year.
The local complication is the shape of any unevenness. On ground that was placed rather than naturally formed, settlement can be localised rather than general, so a floor may have a distinct dip in one area rather than a consistent slope across the room. That distinction is worth noticing before it is screeded over, because a general slope is a levelling job and a localised dip is worth understanding first.
On the older terraces the ground floors are suspended timber over ventilated voids, and there the air bricks are the thing to check. Block them and the void stops breathing and the joist ends begin to go.
Timber acclimatises in the house before it is fixed. Our flooring page covers the coverings we fit and the preparation that goes under them.
