Floors in Leamington raise questions that do not come up in most towns, because a lot of the town’s ground floors are not at ground level.
In a lower ground floor room the slab or the timber sits partly below external ground, and moisture arrives from the sides as well as from underneath. Laying an impermeable covering over that without addressing it traps the moisture and moves the problem into the walls. We establish what is happening before choosing a build up, because the wrong floor in a Regency basement will fail and take the skirtings with it.
Above that level the older housing has suspended timber floors over ventilated voids, with the usual Leamington complication that the air bricks are often behind a lightwell or a later render patch and no longer doing anything. Block the ventilation and the joist ends go. We check before laying.
Regency joist spans are long by modern standards and have usually been cut about by two centuries of plumbers. A floor that bounces is telling you something, and levelling compound will not fix it.
The later housing has solid floors where the questions are flatness and moisture, and most need levelling before a hard covering goes down. Timber acclimatises in the house before it is fixed. Our flooring page covers the preparation underneath the finish.
