Most chimney leaks come from failed flashing, cracked flaunching or eroded pointing in Calne. Calne mixes a stone-built market-town core with Victorian terraces off the London Road and substantial post-war and modern estates on the edges. On this kind of stock, the common problems are nail sickness on the post-war estates, slipped tiles after wind, and failing Victorian leadwork in the older core — and knowing which you are dealing with is the difference between a lasting fix and money wasted.
Chimney repairs in Calne follow the same pattern as across our Wiltshire coverage: lead flashing failures are the primary call, followed by ridge mortar deterioration at the chimney junction and stack repointing. Calne's elevated position accelerates lead fatigue through greater thermal cycling — the temperature differential between summer and winter on this chalk ridge fringe is more pronounced than in the Avon Valley towns.
Victorian and Edwardian properties around Oxford Road require lime mortar on all masonry pointing. The 1980s and 1990s estate housing uses modern brick specification — flexible polymer-modified mortar for chimney pointing, not OPC cement. We assess and specify correctly for each property type as standard practice.
We assess the stack, pots, flaunching and flashing from scaffold or tower — not from the ground.
We identify which of the three common failure points is letting water in — often more than one.
A fixed price with repointing, flaunching, flashing and cowls itemised separately.
Failed elements renewed — lime mortar on period stacks, flexible mortar on post-war.
The stack is left weathertight, with patination oil on any new lead, and guaranteed.
| Job | Typical duration |
|---|---|
| Flashing renewal | half to full day |
| New flaunching | half day |
| Full stack repoint | 1–2 days |
| Cowl supply & fit | 1–2 hours |
| Chimney rebuild (above roofline) | 2–4 days |
Lime mortar on period stacks needs frost-free conditions to cure, so deep-winter repointing is weather-scheduled.
Calne's town-centre streets around The Strand are tight with no side access; the outer estates have generous access for scaffold and skips. Pavement scaffold and skip permits in Calne go through Wiltshire Council; on tight streets like The Strand, Church Street, Curzon Street we allow extra time for setup and access.
Chimney repairs run £150–£800+ depending on scope. Calne pricing tracks Chippenham, adjusted for access on Calne's stock.

Covering SN11 and surrounding postcodes.
Workmanship carries our 10-year guarantee; new lead and pots carry manufacturer warranties, and lime repointing on period stacks is done to conservation standard.
Scaffold for a day or two and some noise during raking-out; we sheet the roof below and clear all debris and old mortar. You do not need to stay home for external work.
Chimney repairs run year-round except hard frost for lime mortar; we make safe and reschedule if the weather won't let mortar cure. Calne sits in the Marden valley, so low-lying properties hold damp longer and the exposed edges catch the south-westerly weather.
"Chimney flashing had been leaking into the back bedroom ceiling for two winters. Reflashed in code 4 lead, ridge tiles repointed at the same visit. Dry since."
"Stack repoint on 1985 semi — mortar completely failed on the exposed north and west faces. Repointed in flexible mortar, flaunching renewed. Done in half a day from scaffold."
"Two ridge tiles displaced at the chimney junction. Relaid and repointed, stack inspected, all clear. Fast, honest, fair."

Yes — more thermal cycling on the chalk ridge means lead fatigue is faster than in valley towns. We recommend chimney inspections every 5 years on Calne properties with original lead flashings.
NHL hydraulic lime mortar — 2.5 or 3.5 depending on the brick hardness. Never OPC cement on Victorian masonry. On modern 1980s brick, flexible polymer-modified mortar is appropriate.
Yes — ventilated caps prevent water ingress while maintaining airflow. Full removal to roof level is also available if preferred.
Active water ingress at the chimney breast ceiling, brown staining around the chimney stack on the plasterwork, or tiles slipping at the chimney junction are all indicators. We survey and diagnose correctly.
