Not sure whether to repair a chimney or remove it altogether? As a rule, repair is best if the stack can be made sound and you still use the flue or value the character it gives your roofline. Removal can make sense if the chimney is redundant, unstable or the source of persistent leaks that are not economical to fix.
Warning signs your chimney needs attention
Chimneys work hard in the South Downs climate. Look out for:
- Leaning or bulging brickwork
- Cracked or missing mortar joints, especially on weathered faces
- Spalled or crumbling bricks, including older Midhurst White bricks
- Loose or damaged pots, cowls or flaunching
- Split or lifted lead flashing and soakers where the stack meets the roof
- Damp stains on ceilings, the chimney breast or in the loft after rain
- Sooty smells, debris or nests blocking a flue
- Tiles slipping around the chimney or water tracking into valleys
If you notice any of these, arrange an inspection. Quick action reduces the risk of water ingress, internal damage and higher repair costs later.
When repair is the right choice
Repair suits most occupied homes where the flue serves a stove, fire or boiler, or where the stack contributes to the look of a period roof. In Midhurst’s cottages and older town properties, a sympathetic repair often preserves character and prevents recurring leaks.
Typical repair options include:
- Repointing with an appropriate mortar to stabilise joints
- Replacing damaged bricks to match existing, then tidying flaunching and pots
- Renewing leadwork with correctly stepped flashing, soakers and back gutters
- Fitting a bird guard or a rain cowl to improve draught and keep water out
- Partial rebuild above the roofline if the top courses are failing
- Ventilated capping of a redundant flue to stop rain while allowing airflow
A good repair addresses the cause, not just the symptom. That might mean fixing nearby tiles, checking valleys, clearing gutters and ensuring rainwater drains correctly away from the stack area. If water is already coming in, temporary emergency repairs can be applied to stop leaks while a full fix is planned.
When careful removal makes sense
Removal can be the best route if the chimney is redundant and beyond reasonable repair, or if its design repeatedly channels water into the roof. This is common on flat roofs or low-pitched extensions where an old stack sits in a splash zone.
Removal options include:
- Taking the stack down to below the roofline, then tiling or slating over to match
- Ensuring the flue remains ventilated at ceiling or wall level to prevent condensation
- Making good rafters, membranes and insulation, then integrating new leadwork
Important checks before removal:
- Confirm the chimney is not shared with a neighbour
- Confirm no appliance relies on the flue
- Consider the impact on the home’s appearance, especially on street-facing roofs
- In Midhurst’s historic core, check with the local authority if consent may be needed
A thorough survey will weigh repair cost against the structural work involved in removal. Where removal is chosen, careful making-good and neat finishing are essential to prevent future leaks.
Midhurst and South Downs considerations
Our area’s climate and setting matter. Chimneys in Midhurst, Easebourne and Fernhurst face strong South Downs winds, driving rain and heavy leaf fall. Overhanging trees shed debris that traps moisture around flashing. The River Rother valley can keep roof timbers damp if ventilation is poor. Period cottages often use clay tiles or slate that need the right fixings and technique around the stack. Older Midhurst White bricks can be soft, so repairs must avoid harsh mortars that can cause damage.
Rural outbuildings and extensions may have flat roofs with upstands around a small stack. These spots collect water and moss, so you may see ponding or staining. Regular checks before winter and after storms help catch issues early. If access is tricky, our team can arrange safe inspection and provide photos from the roof.
What affects the cost
We price transparently. Costs depend on access, height, brick condition, leadwork complexity, tile or slate type and whether a partial rebuild is needed. Removal costs depend on the level taken down to, making-good, any structural supports and finishing materials. We offer a Price Match Guarantee for like-for-like quotes, and we are happy to explain options so you can choose what suits your home and budget.

FAQs
How long does a chimney repair take?
Small repairs such as repointing and new flashing often take a day or two. A partial rebuild can take longer, especially if access scaffolding is needed or weather delays apply.
Can you remove a chimney in winter?
Yes, with weather-safe planning. We use temporary coverings to keep the roof watertight, then make good with matching tiles or slates when conditions allow.
Will I need ventilation if a chimney is removed?
Yes. Redundant flues should be vented to prevent condensation and damp. We will explain the best way to cap and ventilate the flue while keeping the roof secure.
