Subsidence is defined as movement of the foundations of a home, but some degree of movement will always occur. Recently built homes, for example, will need to settle under the weight of the building. Where the home is of very recent construction, the builder will usually return to a new home after six months in order to repair settlement damage. There are a number of factors capable of causing subsidence to Carmarthenshire homes. Collapsed drains can cause subsidence by washing away or loosening subsoil. This may be referred to as groundwater subsidence. On the inside, keep an eye out for new, suddenly visible cracks in brick or render.

Your surveyor may suggest that you talk to an arborist to find out the best cause of action if trees or other plant life is the suspected cause.
