Most chimney leaks come from failed flashing, cracked flaunching or eroded pointing in Box. Box is a Bath-stone village strung along the valley between Bath and Corsham — stone cottages, stone-slate and clay roofs, and steep valley-side plots. On this kind of stock, the common problems are heavy moss on shaded valley roofs, stone-slate slippage, and blocked valleys from the dense canopy — and knowing which you are dealing with is the difference between a lasting fix and money wasted.
Chimney repairs on Box's Bath stone and Cotswold stone properties require lime mortar throughout — NHL 2.5 or 3.5 hydraulic lime, never cement. Lead flashing work uses code 4 or 5 as appropriate to the stack width and exposure. We carry both mortar types and lead codes for Box visits as standard.
The By Brook valley's moisture creates conditions for faster lead corrosion than on higher, drier ground. We recommend chimney inspection every 5 years on Box properties with original lead flashings — the valley moisture can halve the effective service life of under-specified leadwork.
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.
Box's stone cottages sit on steep valley plots with tight lane access, often requiring stone-slate matching and careful scaffold on the slopes. Pavement scaffold and skip permits in Box go through Wiltshire Council; on tight streets like the A4 through the village, Market Place, High Street we allow extra time for setup and access.
Chimney repairs run £150–£800+ depending on scope. Box pricing tracks Chippenham, adjusted for access on Box's stock.

| Flashing renewal | £350–£700 | Code 4 lead |
| New flaunching | £200–£400 | Secures the pots |

Covering SN13 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. Box sits deep in the By Brook valley, so properties are shaded, damp-prone and slow to dry, with heavy tree cover.
"Chimney repointing and lead reflash — done correctly with appropriate mortar, no shortcuts. Dry since. Would recommend without hesitation."

"Ridge tiles displaced at the chimney junction after a storm. Emergency call answered fast, on-site within 2 hours. Tiles replaced and repointed same day."

Depends on the masonry. Victorian and historic brick requires NHL hydraulic lime. Modern post-war brick uses flexible polymer-modified mortar. We assess and specify correctly — wrong mortar causes more damage than no repointing.
Yes — all chimney repointing, reflashing and flaunching work requires scaffold for safe access and quality of work. Scaffold cost is always included in our chimney quotes.
Visible open mortar joints, white salt staining, internal damp at the chimney breast, or tiles slipping at the chimney junction are all indicators. We offer free chimney surveys — many issues aren't visible from ground level.
Yes — ventilated caps prevent water ingress while maintaining airflow. Full removal to roof level is also available. We advise on the most appropriate option based on stack condition and position.
A full repoint and reflash on a standard stack typically takes one day from scaffold. Flaunching only takes half a day. We give a clear timeline in every quote.
