A chimney stack takes more punishment than almost anything else on your house. It stands above the roofline with no tiles to shelter it, catching every gust off the Wolds and every frost that follows a wet spell. Chimney stack repair in Melton Mowbray deals with that damage while it is still local — cracked or spalling bricks, blown mortar joints, a stack starting to lean — before it turns into a job that needs the whole thing taken down.
Tate & Sons Roofing carries out chimney stack repair across Melton Mowbray and the surrounding villages, working alongside our wider chimney services across Melton Mowbray. This page covers how to spot a stack in trouble, when repair beats a rebuild, what drives the cost, and what a repair day actually looks like. Start with a free drone survey and a written quote before anything is agreed.
Spot the Warning Signs Before Your Stack Gets Worse
A chimney stack rarely fails without warning. The signs are there for months, sometimes years, before a stack becomes a genuine hazard — they are just easy to miss from the ground.
Look out for these:
- Cracks running through the mortar joints or across the bricks themselves
- Bricks with a crumbling, flaking or pitted face (spalling)
- A stack that looks slightly out of true against the roofline or sky
- Mortar debris or brick fragments collecting in the gutter
- Damp patches on a chimney breast or ceiling inside the house
- A pot sitting unevenly, or flaunching around the pot that has cracked away
Any one of these on its own is worth a call. Several together, especially a visible lean, mean the stack needs a proper look sooner rather than later. A free drone survey gives you clear footage of the stack from every angle, without anyone going near a ladder, so you know exactly what you are dealing with.
Repair or Rebuild — Getting the Right Call for Your Stack
Localised brick and mortar repair is right when the damage is confined to part of the stack and the core structure is still sound. Chimney stack repair — repointing failed mortar, cutting out and replacing spalling bricks, resetting flaunching — deals with that kind of damage without touching brickwork that is still doing its job.
A full rebuild is a different job for a different problem. If the lean is pronounced, if cracking runs through most of the stack’s height, or if the brickwork has failed from the chimney breast right up to the pots, our chimney rebuilding service takes the stack down and rebuilds it properly.
We check the whole stack before recommending either route, and we will always tell you honestly which one your chimney actually needs. On many jobs around Thorpe Arnold and Burton Lazars, we find a stack that only needs its top few courses addressed — the rest of the brickwork below is sound and does not need disturbing. Repairing only what has failed keeps the job smaller and the cost down, without leaving anything unresolved.
What Actually Makes a Chimney Stack Crack, Lean or Crumble
Most stack damage comes down to water. Porous brick soaks up rain, and when that moisture freezes it expands inside the brick face, forcing off small flakes over repeated winters. That is spalling, and once it starts it gets worse every frost until the brick is replaced.
A lean develops differently. The side of a stack facing the prevailing wind dries out faster than the sheltered side, so the mortar joints on the wet side expand while the dry side shrinks, and the stack tips slowly away from the weather over years.
Sulphate attack — sulphates in the brick reacting with trapped moisture — can push the same lean along faster, jacking the joints apart from within. Removing a chimney breast lower down the house without properly supporting the stack above it is another common cause, and one a roofer spots quickly on an older Melton property. Stacks on the higher ground toward the Vale of Belvoir scarp and around Scalford take a harder, more constant battering than a sheltered stack in Melton town centre. The BRE’s report on chimney airflow sets out how wind behaves around a stack in technical detail. Failed lead flashing where the stack meets the roof lets water track down inside the structure too, and it often gets checked at the same time as a stack repair.
What Chimney Stack Repair Really Costs in Melton Mowbray
Cost depends on how much of the stack has failed and how it needs fixing. As a general guide, repointing a stack with sound brickwork but failed mortar typically runs £300–£800. Cracked or crumbling flaunching around the pot usually costs £150–£500 to replace. Where spalling or cracked bricks need cutting out and replacing, expect the price to sit closer to the higher end of the repointing range, or into partial rebuild territory if several courses are affected.
A partial rebuild — taking down and resetting the top few courses along with the flaunching and pot — typically costs £600–£1,500.
A full rebuild of the stack above the roofline runs £1,000–£3,500 or more, depending on height, the number of flues, and how much brick needs replacing. Scaffolding is usually needed for anything beyond a quick repointing job and typically adds £500–£1,200 on its own.
What pushes a price up or down:
- Access and height — a taller stack or a boxed-in roof needs more scaffolding
- How much brick has failed — a handful of bricks costs far less than a full course
- Mortar type — lime mortar for a period property costs more than standard cement mortar
- Number of flues and pots — more pots mean more flaunching and more careful work
- Flashing and flaunching — repairing these alongside the stack adds to the job but stops the same damage returning
These are general market ranges, not a quote for your chimney — two stacks the same height can price very differently once brick condition and access are factored in. A fixed price needs a survey.
Repointing, Partial Rebuild or Full Rebuild — Comparing Your Options
Once you know roughly what has gone wrong, the next question is how much of the stack needs touching. Our chimney repointing service covers the lightest end of this table, while a full rebuild sits at the other end entirely.
If your survey points toward the far right column, our chimney rebuilding service is the more honest answer than a repair that will not hold. If it points toward the left two columns, stack repair gets the job done without the cost of taking the whole thing down.
| Option | Typical cost | What it involves | Best for |
|---|---|---|---|
| Repointing | £300–£800 | Raking out failed mortar joints and repacking with fresh mortar across the stack | Sound brickwork where only the mortar has crumbled or eroded |
| Partial rebuild | £600–£1,500 | Taking down and rebuilding the top few courses, resetting flaunching and the pot | Localised cracking, a mild lean, or spalling confined to the upper courses |
| Full rebuild | £1,000–£3,500+ | Taking the stack down to roofline and rebuilding it completely, flue liner included where needed | A pronounced lean, or cracking and spalling running through most of the stack |
What Happens on Repair Day, From Scaffold to Sign-Off
A chimney stack repair generally follows the same sequence:
- Scaffold or roof access set up safely around the stack
- Stack inspected closely, confirming the repair matches what the survey found
- Failed mortar raked out, or damaged bricks cut out one at a time
- New bricks or repointing mortar matched to the existing stack and fitted
- Flaunching reset around the pot, and flashing checked where the stack meets the roof
- Site cleared and the finished stack checked before we leave
A straightforward repointing job on a single stack is often finished in a day. A partial rebuild with several courses to replace usually takes 1 to 2 days once scaffolding is up. James Tate, our founder, prices most stack repairs himself, so the person who quotes the job understands exactly what the crew will find once the scaffold goes up. Weather has some say too — mortar needs the right conditions to cure properly, and we will not rush a repair just to hit a date.
Keep a Repaired Stack Sound for Years to Come
A repaired stack should last decades, but a little attention keeps it that way. Chimneys typically need repointing again every 20 to 30 years, sooner on an exposed site.
- Have the stack looked at after any severe storm, particularly on exposed plots
- Keep an eye on mortar joints for early crumbling before it spreads
- Check flashing and flaunching stay intact, since both keep water out of the stack
- Book a free drone survey every few years to catch spalling brick early
None of this needs a specialist visit — just a regular look, and a call to us if anything seems off. A repair caught early is always smaller, and cheaper, than one left to run.
Why Melton Mowbray Homeowners Trust Tate & Sons With Their Chimney
Chimney stack repair only works if the diagnosis is right the first time. Get that wrong and you pay for a repointing job that a leaning stack was always going to outgrow within a year or two. James Tate, our founder, spent fifteen years working roofs across Melton Mowbray and the surrounding villages before starting the business, and he still prices most stack repairs himself — find out what is genuinely wrong, use the right materials, and stand behind the result.
Daniel Oakland, our project manager, brings more than twenty years in the trade and handles the heritage brick and lead detailing that older Melton properties need, including the lime mortar work a period stack near the town centre often calls for. Between the team we carry over 40 years of combined experience, NVQ Level 2 and 3 qualifications in Roofing Occupations, and CSCS cards. Janice Whitmore, our office manager, keeps you updated from the first call through to the finished repair. Read more about the people behind the work on our About Tate & Sons Roofing page.

Got Questions?
Your Chimney Stack Repair Questions, Answered Properly
How do I know if my chimney stack needs repair rather than a full rebuild?
Localised cracking, spalling bricks, or crumbling mortar on an otherwise straight stack usually points to repair rather than a rebuild. A stack only needs a full rebuild when the lean is pronounced, when cracking runs through most of its height, or when brickwork has failed from the chimney breast up. A free drone survey settles this with footage rather than a guess from the ground, so you know which job you actually need before any price is agreed.
What causes a chimney stack to lean or crack?
A lean usually develops because the side facing the prevailing wind dries and shrinks faster than the sheltered side, tipping the stack slowly over years. Sulphate attack, where sulphates in the brick react with trapped moisture, can push the same lean along faster by forcing the mortar joints apart. Cracking often follows frost damage inside porous brick, or from a chimney breast removed lower down the house without proper support left above it.
How much does chimney stack repair cost?
Repointing a sound stack with failed mortar typically costs £300–£800, while flaunching repairs around the pot run £150–£500. A partial rebuild of the top few courses usually costs £600–£1,500, and a full rebuild of the stack above the roofline runs £1,000–£3,500 or more depending on height and the number of flues. Scaffolding, where needed, typically adds a further £500–£1,200, and a fixed price always needs a survey.
Is a leaning chimney stack dangerous?
Any visible lean is worth treating as a priority rather than something to watch for a few more seasons. A leaning stack puts extra weight and stress on the roof timbers beneath it, and that stress increases sharply in high winds, raising the risk of bricks or debris coming down. It does not always mean the stack is about to fail, but only a proper inspection tells you whether repair will hold or whether it needs taking down.
What is spalling brickwork and can it be repaired?
Spalling is when the outer face of a brick flakes, crumbles or breaks away, almost always caused by moisture freezing and expanding inside a porous brick over repeated winters. It is repairable in most cases by cutting out the damaged bricks and replacing them with matching brick, then repointing around the repair. Left alone, spalling gets worse every frost, so the earlier it is caught, the fewer bricks need replacing.
How often should a chimney stack be repointed?
Most chimney stacks need repointing again every 20 to 30 years, though exposed stacks wear faster than sheltered ones. A stack on high ground with little shelter from wind and rain can need attention nearer the shorter end of that range. Regular checks after storms catch early mortar failure before it spreads across the whole stack.
Does a redundant or capped chimney still need stack repair?
Yes, a chimney that is no longer used for a fire or stove still needs its stack kept sound. The brickwork and mortar keep weathering whether or not a flue is in use, and a capped chimney with no ventilation can trap moisture inside the stack, which sometimes makes damage worse rather than better. Capping the flue protects the inside of the chimney from rain, but it does not protect the outer brickwork from frost and wind.
Why do stacks around Scalford and Waltham on the Wolds wear out faster than stacks in Melton town centre?
Villages on the higher ground toward the Vale of Belvoir scarp sit far more exposed to driving wind and rain than the sheltered streets around Melton town centre. That constant exposure speeds up both the frost damage that causes spalling and the uneven drying that causes a stack to lean. We see stacks on these exposed plots needing repair years earlier than a similar-aged stack in a sheltered spot closer to town.
Does a period home near St Mary's Church need lime mortar rather than cement for stack repair?
Often, yes. Older brickwork around St Mary's Church and Melton's historic streets was usually built with lime mortar, which flexes with the brick and lets moisture escape rather than trapping it. Repointing an older stack with modern cement mortar can trap dampness against softer period brick and cause faster spalling. We match mortar type to the age and condition of the brickwork rather than using one standard mix on every job.
