The most common cause of chimney deterioration in Edinburgh is moisture infiltration. Here’s why:

  1. Weather Exposure: Edinburgh’s wet and windy climate exposes chimneys to prolonged moisture and freezing temperatures, which can cause the masonry to crack and deteriorate over time.

  1. Poor Flashing: Damaged or poorly installed flashing allows water to seep between the chimney base and the roof, leading to mortar erosion and structural issues.
  2. Lack of Waterproofing: Without a waterproof seal, rain can penetrate the bricks and mortar, resulting in efflorescence (white staining) or spalling (flaking masonry).
  3. Chimney Caps and Cowls: Missing or damaged chimney caps and cowls let rain and snow into the chimney, causing internal moisture problems and accelerating the breakdown of mortar and brickwork.
  4. Condensation: Modern heating appliances can produce cooler flue gases, leading to condensation that accumulates and damages the internal walls of the chimney.
