Floors in Stratford’s older buildings are the place where modern flooring practice does the most damage, and the reason is simple: these floors were never designed to be sealed.
A traditional solid floor, brick, flag or lime based, sits directly on the ground with no membrane and works by letting ground moisture evaporate from its surface. Lay an impermeable modern floor over the top and the moisture does not stop arriving, it simply leaves somewhere else, which is usually the base of the walls. In a timber framed building that means it leaves through the bottom of the frame, which is the most expensive possible outcome. A significant number of the damp problems we are called to in old Stratford properties date from the year somebody laid a new floor.
Where an original floor survives it is generally worth keeping and worth uncovering. It wants cleaning and repointing in lime rather than sealing, and it will always feel cooler underfoot, which is a fair trade for a floor that has already lasted centuries.
Original boards over historic joists are worth the same consideration, and in a listed building lifting or replacing them can be a consent matter.
On the modern estate housing the floors are conventional solid slabs where flatness and moisture are the questions. Our flooring page covers the coverings and the preparation under them.
