Floors in older Banbury properties raise a problem that modern flooring practice is not designed for: many of them have no damp proof membrane and were never meant to have one.
A traditional solid floor in a stone building, flagstone or brick laid straight onto the ground, works the same way the walls do. Ground moisture rises through it and evaporates from the surface, and the building copes because the moisture has an escape route. Laying an impermeable modern floor over the top does not stop the water, it redirects it, and it usually comes out at the base of the walls instead. A great many damp problems in these buildings date precisely from the year somebody laid a new floor.
Where an original stone or brick floor survives it is usually worth keeping and worth uncovering. It needs cleaning and repointing in lime rather than sealing, and it will always feel cooler underfoot than a modern floor, which is a fair trade for a floor that has already lasted two centuries.
Where a modern floor is genuinely needed, it has to be designed with the walls in mind rather than in isolation, and we will explain the options honestly rather than laying the easy build up and leaving you the consequences.
On the estate housing the floors are ordinary solid slabs where flatness and moisture are the questions. Our flooring page covers the coverings and the preparation under them.
