Why Chimney Repairs Cannot Wait Once Damage Appears
Cracked mortar joints represent the most common cause of chimney damage on properties over 50 to 60 years old. What starts as small cracks quickly becomes serious problems when rainwater penetrates the masonry and causes internal deterioration.
Constant exposure to rain, frost, wind and temperature changes makes bricks and mortar expand and contract. This gradual weakening process damages the structure over time. Unresolved chimney damage spreads into roof timbers and loft spaces, creating hidden water ingress that costs thousands to repair.
Chimney stacks are one of the most common sources of damp penetration on older UK properties. Many chimneys remain unused but still require weather protection because they stay open at the top of the structure. A large proportion of damp and staining around chimney breasts comes from external damage rather than internal moisture.
