Chimney trouble shows as damp on the chimney breast, crumbling mortar, or a leaning stack. On Canterbury’s period roofs it is usually the flashing or the pointing.
When it is not the answer: A sound stack with only tired pointing needs repointing, not a rebuild — we never oversell a rebuild you do not need. Read the full guide.
We inspect the stack, flashing, pointing and flaunching from close up.
Fixed price for the specific work — flashing, repointing, flaunching or rebuild.
Booked in once scaffold or tower access is arranged.
Lead renewed in the correct code, pointing and flaunching in the right mortar for the stock.
Site cleared and the work guaranteed weathertight.
| Job | Typical duration |
|---|---|
| Flashing renewal | Half to one day |
| Repointing a stack | 1 day |
| Flaunching & pot re-bed | Half a day |
| Full stack rebuild | 2–3 days |
Mortar work needs dry, frost-free conditions; we schedule pointing and flaunching accordingly.
Chimney work almost always needs scaffold or a tower for safe standing at the stack; it is itemised in the quote. Scaffold is specified for: most stack work — flashing, repointing, flaunching and rebuilds - always itemised in your written quote, never a hidden extra, and we arrange it.
Canterbury’s medieval core and the Victorian terraces off Wincheap and St Dunstan’s often mean tight frontages, shared rear access and conservation-street constraints, so scaffold and skip placement take planning. Pavement scaffold and skip permits go through Canterbury City Council; allow a few working days on streets like Palace Street, Burgate, St Dunstan’s Street where space is tight.
Lime mortar specialists · Conservation area experience · Canterbury and East Kent
Canterbury has one of the highest concentrations of Victorian and Edwardian chimney stacks of any city in Kent. The terraces of St Dunstan's, Wincheap, Hales Place and the Old Dover Road corridor all have stacks that are now 100–130 years old. Lime mortar repointing, lead flashing overhaul and flaunching renewal are the primary maintenance tasks that keep these stacks watertight, and they are all work we carry out regularly across the city.
The critical issue on Canterbury's period properties is the misuse of cement mortar by previous contractors. Cement is harder than the surrounding Victorian brick and prevents the stack from flexing in wind. Over time, the stress cracks the bricks rather than the joint, creating water ingress paths that go well below the visible surface damage. We always specify lime mortar on pre-1919 stock, whether or not the property is listed or in a conservation area.
Eroded flaunching (the cement cap around pot bases) on Victorian stacks, lead flashing failure at the chimney/tile junction on both plain clay tile and slated roofs, cracked or displaced pots on stacks exposed to northeasterly winter winds from the coast, and efflorescence staining caused by failed pointing allowing salt migration through the brickwork.
“Chimney stack on our Victorian terrace in Wincheap had been repointed badly in cement. Canterbury Roofing stripped it all out, repointed in lime and replaced the lead flashing. Already making a visible difference to the damp on the chimney breast inside.”
“Loose pot on a chimney stack, noticed it moving in the wind. Called in the morning, scaffolded the same week, rebuilt the stack top and fitted a new pot. Solid job.”
“Flaunching had completely eroded on our 1890s terrace. Two cracked pots as well. All replaced, repointed and weatherproofed in one visit. Fair price, tidy work.”

Worked example: Repointing and re-flaunching a Victorian stack in St Dunstan’s with a tower: about £650.
No deposit under £500. Staged payment on rebuilds, materials on site first. Itemised VAT invoice.
Covering CT1, CT2, CT3, CT4 and surrounding postcodes.
Chimney workmanship is guaranteed 10 years; on listed and conservation stacks we point in lime as required.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Scaffold at the stack for a day or two and some mortar debris — sheeted and cleared before we leave. You do not need to stay home for external work - we just need power and access agreed in advance.
Lime and cement mortar need dry, above-freezing weather to cure, so stack work is weather-led. The Stour valley holds humidity, so drying times lengthen in autumn and moss returns fast on north-facing and tree-shaded roofs.
Minor chimney repointing in Canterbury typically costs £150–£350 depending on stack height and access. Lead flashing replacement around a chimney stack runs £250–£600. Pot replacements are £80–£200 per pot. Full chimney stack rebuilds can reach £800–£2,500 depending on height and materials. Conservation area properties requiring lime mortar and matched brick may carry a premium. Free site surveys are always provided.
Routine repointing, lead flashing replacement and pot swaps are permitted development in most cases. However, properties within Canterbury's conservation areas and listed buildings may require approval before chimney stack rebuilds, flaunching changes or pot style changes. We advise on this as part of the survey — do not assume it is straightforward on older city centre properties.
Lime mortar — not cement. Cement pointing on Victorian or pre-Victorian chimney stacks accelerates brick decay because the cement is harder than the surrounding brick and forces any movement stress into the brickwork rather than the joint. Canterbury conservation area properties require lime mortar on chimneys and we use it as standard on all pre-1919 stock regardless of planning status.
Visible signs include crumbling or missing mortar joints on the stack, damp patches on the chimney breast inside the house after rain, loose or leaning pots, white efflourescence (salt staining) on the chimney brickwork, and deteriorated lead flashings at the base of the stack. Any of these warrant a survey. Left untreated, failed chimney flashing is the single most common source of long-term structural water damage we see in Canterbury properties.
Yes. Disused chimney stacks that have not been capped correctly are a common source of moisture ingress and bird nesting on Canterbury properties. We can repoint and cap the stack, replace pots with half-round ventilating cowls, or full cap where no ventilation is needed. We also fit lead soakers on disused stacks to prevent rainwater tracking into the party wall junction.
