The geology of many London areas consists of clay materials and many areas are susceptible to flooding. These two aspects means that many basement flats and cellars can require damp proofing or basement tanking to keep them habitable.

If your home shows signs of damp you already know how unsightly the problem can become. As well as affecting the value of your home, damp frequently gives rise to mould which in turn can affect your respiratory and immune system.

Don’t despair, with prompt diagnosis and treatment including damp proof course (DPC) injections the underlying causes can be addressed and structural damage repaired.
