Floors in Leicester’s Victorian and Edwardian housing are usually better than the owner expects, and that changes what the sensible answer is.
These houses were built with decent quality softwood boards over generous joists, and a great many of them are still there under whatever has been laid on top since. Before specifying a new covering we look at what is underneath, because lifting, cleaning and relaying original boards often produces a better floor than anything that could be bought to replace them, and costs less than a good engineered board.
Sub-floor ventilation is the routine check. The air bricks are doing a job, and on these plots they are regularly blocked by a raised patio, a later extension or fifty years of border planting. Block them and the joist ends begin to go, and a beautiful floor over a rotting one is money wasted.
In a converted flat a floor is also somebody else’s ceiling, and the sound transmission a hard covering creates is a common source of trouble between neighbours. Acoustic underlay is not an upgrade there, it is the thing that keeps the peace, and the lease may well require it.
On the later estate housing the floors are solid and the questions are flatness and moisture instead. Our flooring page covers the coverings we fit and the preparation that goes under them.
