Quick answer: Daniel’s current chimney-repair prices start from £250 for pointing, £300 for flaunching repairs, £350 for flashing repairs, £700 for stack removal and £800 for a stack rebuild. These are starting prices: access, scaffolding, chimney size and the amount of damaged brickwork can change the final quotation.
A chimney repair can mean anything from renewing a small area of mortar to rebuilding an unstable stack. That is why generic online prices often appear inconsistent. The useful comparison is not simply the total—it is the repair specification, access method and work included. You can also review our chimney repair service for the repair options available locally.
Key takeaways
Daniel’s local starting prices range from £250 for pointing to £800 for a chimney-stack rebuild.
Scaffolding, roof access, stack position and hidden water damage can materially change the quote.
Repointing, flaunching and flashing solve different faults and should not be treated as interchangeable.
A persistent chimney leak needs diagnosis before anyone applies sealant or replaces leadwork.
A written quotation should explain the defect, repair area, materials, access and waste removal.

Chimney pointing | From £250 | Weathered or missing mortar joints |
Flaunching repair | From £300 | Failed mortar around chimney pots |
Chimney flashing repair | From £350 | Waterproof leadwork where the stack meets the roof |
Chimney-stack removal | From £700 | Careful dismantling and making the roof watertight |
Chimney-stack rebuild | From £800 | Rebuilding unstable or extensively damaged masonry |
National price guides show much wider ranges because they include larger stacks, extensive rebuilding and costly access arrangements. Daniel inspects the actual chimney before confirming a price, so the quote can distinguish necessary work from optional improvements.

What do the different chimney repairs involve?
Chimney repointing
Repointing removes loose or deteriorated mortar from the joints and replaces it with new mortar. It is appropriate when the bricks remain usable but the joints are crumbling, open or allowing moisture into the stack.
Flaunching repair
Flaunching is the sloping mortar around the base of the chimney pots. Cracks and gaps can admit water or leave pots insecure. The repair may involve removing failed material, re-bedding the pots where required and forming a new weather-shedding finish.
Chimney flashing and leadwork repair
Lead aprons, step flashings, soakers and back gutters help seal the junction between the stack and the roof. Lifted, split or poorly fitted sections can allow water into the roof space. The correct repair depends on which detail has failed and whether the surrounding tiles and mortar are sound.
Local brick, tile or pot repairs
Small repairs may involve replacing spalled bricks, broken roof tiles beside the stack, damaged pots or isolated sections of mortar. Matching materials and safe access can influence the cost more than the number of items alone.
Stack rebuilding or removal
A leaning or badly deteriorated chimney may need partial or complete rebuilding. An unused stack can sometimes be removed above roof level, but the remaining opening must be properly supported, covered and made watertight. Internal chimney breasts are a separate structural matter.
What affects the final chimney-repair cost?
Whether the chimney sits on an outside wall, near the eaves or across the ridge.
The need for scaffolding, a tower or another safe access arrangement.
Stack height, width, number of pots and the area of defective mortar.
The condition of the bricks, flaunching, tiles and leadwork.
Whether water has damaged roof timbers, ceilings or internal finishes.
Material matching on older, period or visibly prominent properties.
Waste removal, weather protection and making good after the repair.
A cheap patch can become expensive if it does not address the actual water route. Conversely, a visibly weathered chimney does not always need rebuilding. A clear inspection should identify which components are defective and which remain serviceable.
Signs that your chimney needs inspecting
What you notice | Possible cause | Likely next check |
|---|---|---|
Damp near the chimney breast after rain | Failed flashing, pointing or flaunching | Inspect the full stack and roof junction |
Mortar falling into the gutter or garden | Weathered pointing or flaunching | Check joint depth and loose masonry |
Loose or leaning chimney pot | Failed bedding or damaged flaunching | Assess stability and safe rebedding |
Cracked or flaking bricks | Saturation and frost damage | Identify whether local replacement is viable |
Daylight or staining in the loft beside the stack | Open flashing or tile defect | Trace the entry point during suitable weather |
Stack visibly leaning | Structural movement or extensive decay | Arrange an urgent professional assessment |
Water near a chimney is not proof that the lead flashing alone has failed. Wind-driven rain can enter through mortar, flaunching, porous masonry or an adjacent roof defect. Diagnosing the whole junction prevents the wrong component being replaced.
Should the chimney be repaired or removed?
Repair normally makes sense when the stack is still required, contributes to the character of the property or can be made safe without disproportionate rebuilding. Repointing, local brick replacement and renewed leadwork can extend the life of an otherwise sound chimney.
Removal may be considered when the stack is unused, unstable and expensive to retain. The decision can involve structural support, ventilation, planning constraints, party-wall issues and the internal chimney breast, so it should not be based on the external roofing quote alone.

What should a chimney-repair quote include?
The fault or defects identified during inspection.
The exact section of pointing, flaunching, masonry or flashing being repaired.
Whether old material will be removed before the new work is completed.
The proposed materials and any important matching limitations.
Scaffolding or access charges and who is responsible for arranging them.
Protection of the roof and property while the work is underway.
Waste removal, clean-up and the workmanship terms.
Photographs are especially useful where the homeowner cannot safely see the work. Daniel can explain the findings before work begins and provide a clear starting point rather than relying on vague descriptions such as ‘chimney repair’.
Frequently asked questions
How much does it cost to repoint a chimney?
Daniel’s chimney-pointing prices start from £250. The stack size, mortar condition and access requirements determine the final figure.
How much does chimney flashing repair cost?
Daniel’s published starting price is £350. A local repair with simple access costs less than renewing leadwork around several sides of a central stack with scaffolding.
Does chimney repair always require scaffolding?
No. Some low or accessible chimneys can be reached using other suitable equipment. Taller, central or complex stacks may require scaffolding so the work can be completed safely.
Can a leaking chimney be repaired in one day?
Many local repairs can be completed within a day, but extensive pointing, rebuilding, access setup and unsuitable weather can extend the job.
Is chimney repointing the same as flaunching?
No. Pointing renews mortar between the bricks. Flaunching is the sloping mortar around the chimney pots at the top of the stack.
Will new flashing stop every chimney leak?
Only when defective flashing is the actual cause. Cracked flaunching, open mortar joints, damaged bricks and adjacent roof defects can create similar symptoms.
Can an unused chimney stack be removed?
Often, yes, but the structure, remaining chimney breast, ventilation, roof covering and any planning or party-wall implications must be considered before work starts.
