Just as prevention is always better than cure, maintenance is preferable to major repairs. However, such repairs may not always be avoidable.
The building may develop structural problems, materials will eventually wear out, older repairs may contribute to decay, there may be fungal or insect infestations, or the building may need redecoration.
Whatever the repair needs of your church, it is important to establish the cause of the damage in order to avoid repeated decay and loss of original fabric.
Therefore, the first step should always be to consult your professional adviser about any suspected or perceived damage as they can best determine the cause and extent of the damage and advise you on suitable repair methods.
Detailed advice on the repair of historic floors can be found in the Historic Floors Guidance Note, published in conjunction with the Society for the Protection of Ancient Buildings.
