Why chimneys fail

Exposed on every side, and usually forgotten

A chimney stack is the only part of a house that gets rain on all four faces, dries out fastest, freezes first and has a hole running down the middle of it. It is unsurprising that mortar joints erode, flaunching cracks and pots work loose — what is surprising is how rarely anyone looks at one until damp appears on the breast downstairs.

Most chimney damp comes from one of four places: eroded pointing letting water into the brickwork, cracked flaunching around the pots, failed lead where the stack meets the roof, or a redundant flue with no ventilation and no cap. We check all four rather than fixing whichever is easiest to reach.

  • Pointing, flaunching and lead all assessed
  • Redundant flues capped and ventilated
  • Pots re-set or replaced where loose
  • Scaffolded access, never worked off a ladder

What we do

Chimney work from pointing to rebuild

Whether the stack needs an afternoon or a week, the same team handles the brickwork and the leadwork together.

  • Repointing

    Eroded joints raked out and repointed in a mix suited to the original brickwork, not a hard modern mortar that traps damp.

  • Flaunching

    The mortar bed around the pots cut out and re-formed with a proper weathering fall so water runs off rather than in.

  • Rebuilds

    Stacks taken down to a sound course and rebuilt where the brickwork has spalled, leaned or cracked beyond repointing.

  • Lead flashings

    Front aprons, stepped flashings, soakers and back gutters re-formed as a set so the whole junction works together.

  • Cowls & caps

    Cowls to keep rain and birds out of a working flue, and vented caps for flues that are no longer in use.

  • Removals

    Redundant stacks taken down and the roof made good and weathertight across the opening.

What to look for

Signs your chimney needs attention

Chimney trouble usually shows up as damp inside long before anything looks wrong outside.

  • Damp patches or staining on the chimney breast indoors
  • A tide mark that darkens after wind-driven rain
  • Mortar joints visibly eroded or missing between bricks
  • Cracked flaunching, or pots that look loose or tilted
  • Brick faces flaking and crumbling away
  • A stack that has developed a visible lean
  • Mortar and grit collecting in the gutters below

Loose brickwork or a leaning stack over a public footpath should be looked at quickly — call us rather than emailing.

  • How much does chimney work cost?

    It depends on the stack and on access, which is often the biggest single factor — a chimney in the middle of a roof slope needs more scaffolding than one on a gable end. Repointing is at the lighter end, a full rebuild at the heavier. We look before we quote, and the quotation is itemised so you can see the access cost separately.

  • Do I need scaffolding for chimney work?

    For anything beyond a very quick inspection, yes. Chimney work is not something to do off a ladder, both for safety and because the quality of the work depends on being able to reach all four faces properly. Access is included in your written quote.

  • Should I remove a chimney I no longer use?

    Not necessarily. A capped, ventilated stack costs very little to maintain and keeps the appearance of the building, which matters on a period terrace. Removal makes sense where the stack is structurally poor or where it is causing recurring problems. It is worth taking advice before deciding, particularly on a shared party stack.

  • Why is my chimney breast damp when the fire is not used?

    Usually because the flue is open at the top and unventilated at the bottom, so moisture condenses inside it, or because water is getting in through eroded pointing or cracked flaunching. An unused flue should be capped at the top and vented at the bottom so it can breathe.

  • Can you match the brickwork on a period property?

    We source bricks and mix mortar to suit the original as closely as we can, using a lime-based mix where the building calls for it rather than a hard cement mortar that will trap moisture and damage soft old bricks.

  • Do you also sweep chimneys or line flues?

    No — we cover the structure and weathering of the stack rather than the flue itself. For sweeping or lining a working flue you will want a specialist, and we are happy to say so rather than take on work outside what we do.
