📞 Call Now: 0124 235 2251Cheltenham's Regency and Victorian properties carry some of the most complex chimney stacks in the South West — tall, multi-flued, often in exposed positions on high terraces facing the Cotswold escarpment. We work on all of them.
Eroded mortar joints allow water ingress and progressive freeze-thaw damage. We rake out and repoint using the correct mortar mix — NHL lime for period properties, cement-lime blend for modern stacks. From £150.

Chimneys take the full force of Cheltenham's weather and are the single commonest source of a leak that shows up nowhere near the stack. Spotting the early signs stops a small repointing job becoming a full rebuild.
When it is not the answer: A sound stack that just needs repointing or a new flaunching doesn't need rebuilding — and a redundant chimney you never use can often be removed below the roofline and capped instead, which is cheaper than a rebuild. Read the full guide.
Cheltenham's roofscape is defined by its Regency and Victorian chimney stacks. The terraces of Montpellier, Lansdown and the Pittville estate carry tall, multi-flued stacks that sit above exposed ridge lines — catching the full force of south-westerly storms that funnel up the Severn Vale. These stacks were originally built in soft lime mortar that has been progressively eroded by 150+ years of Gloucestershire weather. Many have never been properly repointed.
The most common call-out pattern we see in Cheltenham is lead step flashing failure on north and west-facing chimneys, combined with mortar loss from the stack haunching — the angled mortar fillet at the base where the chimney meets the roof slope. Once this junction fails, water tracks down behind the lead and into the roof space, often appearing inside on a ceiling that is several metres from the actual leak source.
Cheltenham Borough Council's conservation area guidelines and listed building requirements specify lime mortar for repointing on historic masonry. Using modern cement mortar on Victorian or Regency brickwork creates a joint harder than the surrounding brick, trapping moisture and accelerating brick spalling. We use correctly specified NHL (Natural Hydraulic Lime) mortars for all period chimney work in the borough.
Rake out and repoint. Lime mortar on period/conservation area properties, cement-lime blend on standard stacks.
Step flashings, back gutter and soaker replacement. Code 4 lead minimum, correctly dressed and fixed.
Per pot, including removal of existing, rebed in mortar and installation of new or matched replacement.
Partial or full rebuild. Price depends on stack height, number of flues and access requirements.
We inspect the stack close up — brickwork, mortar, flaunching, pots and the all-important flashing — because most 'chimney leaks' are actually failed lead, not failed brick.
A fixed price for the specific work: repointing, a new flaunching, re-dressing or renewing the lead flashing, pot replacement, or a partial or full rebuild if needed.
Chimney work almost always needs scaffold or a working platform at the stack; we arrange it and any permit, and book a firm date.
We repoint in matched (lime where conservation requires) mortar, renew flaunching, re-dress or replace lead flashing to code, and match brick and pots on rebuilds to keep period stacks in character.
Scaffold struck, debris cleared, and the finished stack and flashing checked for weathertightness before we hand over the guarantee.
| Job | Typical duration |
|---|---|
| Flashing re-dress or repair | Half to 1 day |
| Repointing a stack | 1–2 days |
| New flaunching + pot repair | 1 day |
| Partial or full stack rebuild | 2–4 days |
Mortar and flaunching need dry, above-freezing conditions to cure, so we avoid pointing a stack in hard frost or persistent rain.
Chimney work sits at the highest, most exposed point of the roof, so it nearly always needs scaffold or a proper working platform — a ladder won't do it safely. Scaffold is specified for: almost all chimney work, given the height and exposure of the stack - always itemised in your written quote, never a hidden extra, and we arrange it.
Cheltenham's Regency terraces in Montpellier and Lansdown have railings, lightwells and shared party walls that limit rear access, so pavement scaffold and skip space usually need a permit. Pavement scaffold and skip permits go through Cheltenham Borough Council; allow a few working days on streets like Montpellier Street, the Suffolks, the terraces off St Paul's Road where space is tight.
| Job | Typical range | Notes |
|---|---|---|
| Lead flashing re-dress/repair | £250–£600 | Excl. scaffold where needed |
| Repointing a stack | £350–£800 | Lime mortar on period stacks |
| New flaunching + pot refit | £300–£700 | Per stack |
| Chimney rebuild (above roof) | £1,200–£3,000 | Matched brick and pots |
| Removal & cap (redundant stack) | £600–£1,500 | Take down below roofline, make good |
Worked example: Repointing and re-flaunching a single Victorian stack in the Suffolks with new lead apron flashing, including tower access: around £780.
Chimney jobs under £500 take no deposit. Larger stack works are invoiced on completion or in two stages, never before materials and scaffold are on site.
Chimney repairs carry a written 10-year workmanship guarantee; on conservation-area stacks we use lime mortar for breathability and long-term compatibility with period brick.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Chimney work means scaffold at roof level for a few days and some brick and mortar debris; internal fireplaces are unaffected and you don't need to be home. You do not need to stay home for external work - we just need power and access agreed in advance.
We point and re-flaunch in dry, mild conditions; lead flashing work can be done in most weather but we won't lay fresh mortar into frost. Cheltenham's sheltered vale position brings damp Cotswold-edge autumns and heavy leaf fall from the town's many mature trees, which keeps north-facing slopes slow to dry.
"Had a serious leak appearing on the bedroom ceiling that turned out to be coming from the chimney flashing on the north-facing side. They found it immediately, replaced the step flashings in code 4 lead and used lime mortar to repoint the haunching. Leak gone completely."
"Three chimney pots came down in the January storm. They made them safe the same day, came back later in the week to rebuild the top of the stack with matched lime mortar and new pots. Conservation officer was happy. First-rate work."
"Full chimney stack rebuild on our Grade II listed terraced house. They sourced matched imperial brickwork and used the right NHL lime mix — the conservation officer signed it off without any issues. Wouldn't use anyone else for period work in Cheltenham."
Chimney repointing in Cheltenham typically costs £150–£500 depending on the extent of work and access. Lead flashing replacement costs £200–£600. Full chimney stack rebuilds range from £800–£2,500+. We provide free, no-obligation quotes on all chimney work.
Yes. Lime mortar is required for repointing on period properties in Cheltenham's conservation areas and on listed buildings. Using cement mortar on soft Victorian or Regency brickwork causes accelerated damage to the surrounding masonry. We use the correct mix for each property.
Common signs include: mortar crumbling or missing from joints visible through binoculars, white efflorescence on the chimney breast inside the loft, damp patches on ceilings near the chimney, loose or wobbling chimney pots, and lead flashing that has lifted or cracked at the junction with the roof.
Yes. We carry out chimney repairs on listed buildings across Cheltenham's conservation areas. This includes matched lime mortar repointing, historically appropriate flashing materials, and advising on whether listed building consent is required before work begins.
Every 5–7 years. Lead flashings on north-facing chimney stacks age faster. Properties adjacent to trees should be inspected more frequently as debris accumulates in flashing joints and accelerates lead fatigue.
Haunching is the mortar fillet sealing the joint between lead flashing and chimney brickwork. When it fails, water enters behind the flashing. It is one of the most commonly missed items in roof inspections. We check haunching as standard on all Cheltenham chimney visits.
Yes. We carry out structural chimney removals including making good the roof covering at the point of removal. Conservation area properties may require planning consent before removal — we advise during the survey.
