Apart from occasionally cleaning the flue, most people ignore their chimney until something major happens, though neglecting chimney maintenance can prove expensive. Generally the initial damage goes unnoticed. Small cracks in the mortar can appear that get worse over time; brickwork gets penetrated by moisture which freezes when the temperature drops causing cracks and fractures; the surface becomes flaky and the brick gradually disintegrates, a process known as spalling.
If left too long, damage can become serious. The chimney structure becomes increasingly weakened and vulnerable to storm damage, leaks occur and the rest of the building structure becomes vulnerable to water damage; and problems become increasingly expensive to fix.
Most of these problems can be avoided by a little maintenance such as repointing the mortar and repairing any bricks that have become weakened. Typical chimney repairs and maintenance that we undertake are:
- Chimney repointing
- Repairing and replacing cracked mortar on chimney crowns
- General repairs to chimney stacks
- Replacing dislodged bricks
- General brickwork
- Replacing damaged chimney pots
- Repair of lead flashings
