Floors in the older parts of Northampton have often had a harder life than floors elsewhere, because in this town the ground floor of a house was sometimes a place of work.
Outwork was normal in the boot and shoe trade, which means a front room or a rear addition may have carried benches, materials and stock rather than furniture. Some of those floors were strengthened, some were simply used until they sagged, and many were patched repeatedly. Before specifying a covering on this stock we lift a board and look, because a floor that has been repaired in three different decades will telegraph every junction through a hard finish within a year.
Sub-floor ventilation is the routine check on any suspended floor. The air bricks are doing a job and the number rendered over, planted in front of or built up against by a later extension is remarkable. Block them and the joist ends begin to go, and a beautiful floor over a rotting one is money wasted.
On the estate housing the floors are solid and the questions are flatness and moisture instead. Most need levelling before a hard covering, and we test for moisture rather than trusting how a slab looks.
Timber acclimatises in the house before it is fixed. Our flooring page covers the coverings and the preparation under them.
