Brick homes will be subject to both minor and serious issues, ranging from horizontal cracking to damp course proof failure. Rapidly deteriorating cement mortar caused by sulphate attack is an example of a serious issue, which may require the outright demolition of a wall if discovered and may require immediate attention. The consequences of amateur repairs can either worsen the problem or create entirely new defects in a brick wall. Seeking professional advice can reduce the risks in this area.
