Common Chimney Problems We Deal With:

We regularly attend properties across London to resolve issues such as:

  • Leaking chimney flashings
    Split, perished or poorly fitted lead flashings and soakers allowing water to track under roof coverings and into the loft or ceiling below.
  • Deteriorated mortar joints
    Weathered, cracked or hollow pointing to chimney stacks, copings and flaunching, leading to water ingress and loose masonry.
  • Loose or spalling brickwork
    Frost-damaged bricks, unstable stacks or leaning chimneys that require making safe and rebuilding.
  • Defective chimney pots and cowls
    Cracked or loose pots, missing cowls, birds’ nests and debris reducing ventilation and allowing rain into the flue.
  • Redundant or unused chimneys
    Historic flues no longer in use that still admit water, draughts and debris if not properly capped or ventilated.

If you’re not sure exactly what’s wrong, we can carry out a roof-level inspection and provide photos and a written summary of our findings, so you can see precisely what needs attention.
