Perished brickwork is probably one of the most common defects found by our surveyors. The phenomenon can be associated with other issues that either cause the problem or exasperate it. Something as simple as using materials that are unsympathetic to the building can cause masonry to deteriorate, such as cement based mortars and renders. Cement pointing can help to trap moisture around the edge of the brick and then when freezing temperatures expand the liquid, the fair face of the brick can break away. This can lead to further accelerated deterioration. Cement render can also trap moisture behind the surface causing dampness and accelerated deterioration. Our building surveyors normally recommend that lime mortars, renders and plasters are used as they are air permeable and allow trapped moisture to escape more easily.
