Chimney repair in Exeter costs from £300 for repointing a standard stack to £1,500+ for full lead replacement and crown rebuild on a complex Victorian chimney. This guide covers the most common chimney repair types, their typical costs in Devon, and what to look for in a quote.
| Job Type | Typical Cost | Notes |
|---|---|---|
| Chimney repointing (standard stack) | £300–£700 | Includes all four faces. Lime mortar on pre-1900 stock. |
| Crown replacement | £150–£350 | Lime or polymer mortar. Full crown removal and relay. |
| Lead step flashing replacement | £400–£750 | Full code 4 lead replacement, correctly dressed. |
| Lead back gutter replacement | £300–£600 | Code 5. Soldered joints. Drainage fall checked. |
| Full chimney lead system (stack & valley) | £700–£1,400 | Apron, steps, back gutter, any cover flashing. |
| Chimney pot replacement (per pot) | £80–£200 | Including bedding mortar and any crown work. |
| Chimney stack rebuild (per 1,000 bricks) | £800–£1,500 | Structural rebuild. Usually required when settled or leaning. |
| Ventilated chimney cap (disused flue) | £150–£350 | Purpose-made cap. Maintains air circulation. |

A chimney at ridge height on a 2-storey property requires full scaffolding. This adds £400–£800 to the job. A chimney on a single-storey extension may be accessible from a ladder. Access is assessed at the survey.
Lime mortar is required on all pre-1900 Exeter properties and should be hydraulic lime matched to the hardness of the original brickwork or stonework. The correct mix costs modestly more than standard cement but protects the masonry from the spalling caused by differential thermal movement. For Exeter’s high proportion of Victorian and Georgian housing, lime mortar is the correct choice, not an optional upgrade.
Lead is quoted by area and code. Code 4 for step and cover flashings; code 5 for back gutters and any application with standing water risk. Lead that has been previously patched extensively may need full replacement even where only one point is visibly leaking — fatigued lead fails at multiple points within 2–3 years of any patch repair.
Exeter’s conservation areas cover the city centre, St Thomas and parts of Heavitree. Chimney work on visible elevations in these areas should use appropriate materials. Listed buildings require consent for structural alterations to chimney stacks.
For Exmouth and Dawlish properties, marine-grade sealant at the lead-to-masonry interface extends the service life of chimney flashings measurably. We apply it as standard on all coastal chimney work.
A reputable Devon chimney repair quote should specify: the access method and whether scaffold is included; the mortar mix (lime type and NHL strength, or cement spec on modern stock); the lead code for any flashing work; whether the back gutter is included in flashing replacement; the condition of the four chimney faces at the time of survey; and the guarantee period for the work. A quote that lists ‘chimney repointing’ without specifying the mortar type is not a complete specification.
If a roofer quotes cement repointing on a Victorian or Georgian Exeter property, this is incorrect specification. Cement mortar causes accelerated masonry damage through differential thermal movement on pre-1900 brick and stone.
If the lead on your chimney is more than 50 years old and has been patched before, patch repair is not a durable solution. A quote that offers patch repair on old lead without recommending assessment for full replacement is not giving you the complete picture.
The back gutter is the part of the chimney lead installation most prone to failure. A quote that covers step flashings but does not mention the back gutter may not be assessing the full installation.
Any chimney at ridge height on a two-storey property requires scaffolding. A quote that doesn’t mention access method for a tall chimney is either using unsafe ladder-only access or has not accounted for scaffold cost.
“Victorian chimney on our St Thomas terrace. Lime mortar specified correctly, lead replaced in full. No more damp in the chimney breast.”
“Survey found the back gutter had failed as well as the step flashings. Full replacement. Good that they checked the whole installation rather than just the obvious leak.”
“Coastal chimney in Exmouth. Marine-grade sealant used at the lead junctions. Correct specification for the location.”
From £300–£700 per stack depending on size, access and mortar specification. Free survey. Call 01392 759 295.
Victorian chimneys in Devon typically require repointing every 15–25 years depending on exposure. Tiverton’s valley position and Exmouth’s coastal environment mean faster deterioration than sheltered Exeter suburbs.
No — a cracked crown allows water entry to the top of the chimney stack. Water in the stack leads to internal damp, mortar deterioration from the inside, and eventual structural deterioration. Crown repair is one of the most cost-effective chimney maintenance items.
Yes — with a ventilated purpose-made cap. Never foam fill. A capped but ventilated chimney prevents rain entry while maintaining the air circulation that prevents condensation in the flue.
Correctly specified and installed lead lasts 40–60 years on sheltered Exeter properties. Coastal properties see 30–40 years. Heavily fatigued lead from the 1960s–80s may be at or past end of life regardless of age.
Not in most cases. A visual inspection from the roof during the repair survey is usually sufficient. Where a stack has moved significantly out of plumb or shows signs of structural settlement, a more detailed structural assessment may be recommended.
Yes — 10-year workmanship guarantee on all chimney repair work. Call 01392 759 295.
Free survey, no call-out fee, no obligation. An honest price from a Devon roofer who turns up when they say they will.
