The external walls of a house are the frontline defences of our homes. Not only do they hold the building up but they also prevent the elements from penetrating through into your home. When properly constructed and well-maintained they also keep the interiors warm and comfortable.

Their ability to perform well, resisting the continual onslaught of the elements relies on you, as the homeowner, being able to quickly identify early signs of failure and putting them right. Carrying out render repair work where necessary and maintaining your brickwork is vital.
