Chimney Repair Cost

When needing a chimney repaired, there are many repairs you may want to consider, ranging from minor repointing to flashing work or partial or complete rebuilding. When having a chimney repaired, you can revitalise the space, address water and condensation leaks and lower the risk of more serious problems developing.

In this guide, we’ll explore a wide range of chimney repair costs based on 2026 UK prices.

The main cost factors include the type of repair, chimney size, height and accessibility, scaffolding/access requirements, condition of brickwork, mortar deterioration, flashing, chimney pots/cowls, roof condition and the extent of structural damage. Chimney repairs generally involve working at height, so access can form a significant part of the total cost.

So, let’s dive in!

How Much Does Chimney Repair Cost?

To begin, let’s discuss chimney repair costs in general. Minor chimney repairs can cost around £150-£300, while more substantial work such as repointing, flashing repairs or rebuilding can cost anywhere from several hundred to several thousand pounds.

Below are some prominent examples and their average costs in the UK in 2026:

Labour should be considered along with access costs rather than assuming the visible repair itself accounts for the majority of the bill.

Chimney Repair Costs and Timescales

These are general estimates, and the price can vary significantly depending on the exact problem and whether scaffolding or other access equipment is required.

Chimney Repointing Cost

The average cost of repointing a chimney is around £500-£1,000 and involves removing the chimney mortar between bricks that has been worn down or damaged before adding new mortar to revitalise and re-strengthen the chimney. Chimney repointing costs can vary depending on where you live too.

Once deteriorated mortar is removed, the joints can be repointed by the tradesperson carrying out the work. Localised and complete stack repointing differ in that the former will be a quicker job if only some of the chimney mortar needs replacing and naturally less expensive, and the opposite for a complete stack repointing.

Cost also differs based on chimney size, with repointing for a larger example possibly costing up to £1,000. Chimney repointing costs also depend on mortar type and accessibility.

As alluded to earlier, scaffolding or another suitable access method may be required and can add considerably to the total cost.

Please be aware that repointing isn’t a solution for bricks or masonry that have deteriorated beyond repair. In this case, further assessment will be needed to establish whether brick replacement or rebuilding is required.

Chimney Flashing Repair Cost

Chimney flashing is a weather-resistant covering for house roofs that fits around the junction between the chimney and roof. Flashing repair may cost between £200 and £800 on average. However, the price will vary depending on a range of factors.

Minor repairs may cost around £200-£300, and partial replacement work will also tend to sit towards the lower end of the price range. Complete flashing replacement will naturally be towards the higher end, possibly reaching around £800.

Lead flashing, where applicable, can cost more than some alternative materials. The price will also rise if scaffolding is needed or if you’re seeking to have surrounding tiles or slates repaired at the same time.

It’s important to keep in mind that water appearing around a chimney doesn’t automatically mean the flashing is responsible. The source of the leak should be identified before deciding which repair is needed.

Leaking Chimney Repair Cost

If you have a leaking chimney, it is important to have the issue addressed promptly to avoid damage accumulating or further problems arising. Do keep in mind that the source of water ingress should be identified before recommending a particular repair.

The average cost of having a leaking chimney repaired is around £200-£1,000. This is a wide range because the work involved can vary considerably depending on the cause, condition of the chimney and extent of the leak.

Common causes of a leaking chimney include:

• Damaged flashing
• Damaged bricks
• Deteriorated mortar
• Chimney pot problems
• Damaged flaunching
• Roof defects around the stack
• Water entering an unused or open flue
• Internal condensation or damp issues

A simple localised repair may therefore cost a few hundred pounds, while a leak involving several parts of the chimney or surrounding roof could cost considerably more.

Chimney Flaunching Repair Cost

Chimney flaunching is the weathered mortar that fits around chimney pots in a slope found at the top of a chimney stack. This helps secure the chimney pot and directs water away.

On average, chimney flaunching repair costs land around £150-£300.

Common issues with chimney flaunching include cracking, deterioration and loose chimney pots. Depending on the condition, a local repair or complete replacement may be needed.

Chimney Pot Repair and Replacement Cost

Chimney pot repair costs around £200-£300, whereas the price of a full replacement will land between £300 and £500.

Prominent issues when it comes to chimney pot damage include loose pots, cracked or damaged pots and degraded mortar, whereby re-bedding may be needed. In addition, replacement or removal work may sometimes be required.

The condition of the flaunching may need to be addressed at the same time, so this is worth checking when the chimney pot is inspected.

Chimney Cowl Replacement Cost

Chimney cowls act as a protective cover for a chimney flue or pot and can help limit downdraughts and prevent debris and rain from entering, depending on the type used.

Chimney cowl replacement costs around £200-£400.

Potential reasons a chimney cowl may need replacing include a damaged existing cowl, bird or rain protection, ventilation requirements and appliance/flue requirements.

The appropriate type of cowl depends on the chimney and whether it serves an appliance, so this should be established before a replacement is fitted.

Chimney Brick Repair Cost

For having chimney bricks repaired, the price can come to around £500-£1,500.

Common chimney brick repairs include addressing:

• Spalled bricks
• Cracked bricks
• Loose masonry
• Individual damaged bricks
• Larger areas of deterioration

Replacing isolated bricks differs significantly from rebuilding the chimney stack, so the condition and extent of the damaged masonry will have a substantial impact on the price.

Chimney Stack Repair Cost

In the case of needing a chimney stack repaired, it can cost around £200-£800 for more localised work.

A chimney stack repair may feature repointing, brick replacement, flashing, flaunching, pots or cowls.

It’s important to know the difference between a specific component repair and a broader chimney stack refurbishment, as more extensive deterioration can push costs considerably higher.

Chimney Rebuild Cost

For more extensive deterioration, a partial or full rebuild may be required. Let’s explore average costs for different rebuild jobs.

These costs vary considerably depending on the size and height of the chimney, the amount of masonry involved, materials, access and whether pots, flaunching or flashing also need replacing.

Structural concerns are not something homeowners can diagnose solely from ground level, making it important to have the chimney properly assessed.

Chimney Crown Repair Cost

A chimney crown is a slab covering that fits atop some chimney structures.

Repair costs may land around £200-£600.

Minor repairs will be towards the lower end. However, in some cases a more extensive repair job may be needed depending on the extent of the deterioration.

Chimney Breast Repair Cost

When it comes to chimney breast repair, there is a difference between internal and external repair work, with external work designed to address the weather-facing structure. However, the internal chimney breast or flue may need attention too.

Chimney breast repair costs can usually land between £200 and £1,000.

If the issue involves structural cracking or alteration to the chimney breast, costs and requirements can differ considerably from external chimney repairs.

On the other hand, chimney breast removal costs can land around £2,000-£3,000.

What Affects Chimney Repair Costs?

There are many factors that can affect the cost of chimney repairs, and in this exploration we’ll look at a range of considerations.

Type of Repair

Repointing, flashing and rebuilding involve very different amounts of work. So, the type of repair needed will affect the cost, with a rebuild running into the thousands while other work may cost considerably less.

Chimney Size

As for chimney size, it’s important to consider that larger stacks require more labour and materials. This is another thing worth discussing in advance with the contractor you hire.

Condition

It’s also worth considering that the condition of a chimney can turn a minor repair into a larger project due to extensive deterioration.

This is why having problems addressed early can be worthwhile, as deterioration may become more extensive over time.

Property Height

Another notable factor is the height of a property, and in the case of taller properties, this may require more extensive access arrangements.

For example, if scaffolding is needed, it can add several hundred pounds or more.

Roof Pitch

Beyond that, steep or difficult roofs can also affect access and, in turn, impact chimney repair costs. More difficult access can lead to additional labour and equipment requirements.

Scaffolding

As discussed, scaffolding can also increase the overall cost of a chimney repair.

The amount you pay depends on the height of the property, how much of the building needs scaffolding and how long it is required.

Materials

Brick, mortar, lead and replacement pots can all affect costs.

The type and amount of materials needed will therefore have an impact on the total price.

Listed/Historic Buildings

If you live in a listed or historic building, costs may be higher if particular materials or repair methods are required.

Depending on the work, listed building consent or other permissions may also need to be considered.

Location in the UK

Labour rates differ across the UK, varying geographically. For example, chimney repair costs tend to be higher in London and the South East of England than in some other areas of the UK.

Scaffolding Costs for Chimney Repairs

Not every repair uses the same access method, and scaffolding costs can vary substantially depending on the property and work involved.

These are general estimates rather than fixed rates. Chimney-level scaffolding can be more involved than standard access because the scaffold may need to extend above the roofline or bridge obstacles.

To find local scaffolders near you, take a look at our local scaffolder directory.

Additional Chimney Repair Costs

Let’s now take a look at some additional jobs that may need to be considered alongside chimney repairs.

These aren't necessarily part of every chimney repair. For example, damp around a chimney breast may require the cause of the moisture to be identified before a suitable repair and price can be established.

Chimney Repair After Storm Damage

In regard to chimney repair after storm damage, this can come in many forms such as loose pots, damaged cowls, dislodged masonry, flashing damage and roof damage around the chimney.

Do not approach or work beneath visibly unstable masonry unnecessarily.

On average, the cost of a chimney repair after storm damage could be several hundred pounds, although substantial structural damage may cost considerably more.

Emergency Chimney Repair Cost

In the case of an emergency chimney repair, common issues can include loose masonry, unstable chimney pots, significant water ingress and storm damage.

An emergency visit may involve making the area safe or temporary weatherproofing, with permanent repairs completed later.

Emergency work may cost more than a planned repair due to call-out charges and the need for urgent attendance.

Chimney Repair on a Listed Building

For a listed building, chimney repair may involve additional considerations surrounding original materials, mortar, brickwork, pots and the external appearance of the building.

Whether listed building consent is required depends on whether the proposed work would affect the building's character as a building of special architectural or historic interest.

Routine like-for-like maintenance and repair may be treated differently from alterations, removal of chimney features or substantial rebuilding.

If you're unsure, contact your local planning authority before starting the work.

Does Chimney Repair Need Planning Permission?

Planning permission isn't automatically required for every chimney repair.

Routine maintenance and like-for-like repairs can often be carried out without planning permission, but requirements can differ where the work materially changes the chimney or roof.

Additional restrictions may apply to listed buildings and properties in conservation areas, and listed building consent is separate from planning permission.

If the chimney is being substantially altered, rebuilt or removed, it’s worth checking the requirements with your local planning authority before work begins.

Chimney Repair Building Regulations

Building Regulations may become relevant in the case of structural rebuilding, flue alterations, chimney removal or work involving combustion appliances.

That said, not every flashing repair or repointing job will involve Building Control approval.

The requirements depend on the nature and extent of the work, so this should be checked before substantial alterations are made.

Chimney Repairs and Gas Appliances

In the case where a chimney or flue serves a gas appliance, you’ll want to make sure to distinguish masonry or roofing repairs from gas work.

Work on the masonry surrounding a chimney isn't necessarily gas work. However, work that affects the gas appliance or its flue should be carried out by a Gas Safe registered engineer who is registered for the relevant type of work.

Chimney Repairs and Wood-Burning Stoves

For where a chimney serves a wood-burning or other solid-fuel appliance, you’ll want to keep in mind relevant flue and combustion requirements.

Some chimney masonry work can be carried out separately from the appliance itself. However, work involving the installation or alteration of a solid-fuel appliance or its flue must comply with the relevant Building Regulations.

A HETAS-registered installer is one route for having certain solid-fuel installation work self-certified where applicable.

How Long Does Chimney Repair Take?

In this section, we’ll explore how long it takes to repair a chimney, covering a range of different chimney jobs with a typical timescale for each.

It’s important to consider that, with all this, weather can significantly affect external chimney work.

The timescale can also increase if scaffolding needs to be erected before the repair begins.

How Do I Know If My Chimney Needs Repairing?

When it comes to a chimney needing repairs, potential warning signs include:

• Missing or deteriorating mortar
• Loose bricks
• Spalled bricks
• Cracks
• Damaged flashing
• Leaning or visible movement
• Loose chimney pots
• Water ingress
• Damp around the chimney breast

Do not climb onto the roof to inspect the stack yourself. If you're concerned about its condition, arrange for the chimney to be inspected using suitable access equipment.

Can I Repair a Chimney Myself?

Chimney repair typically involves working at height, roof access, masonry, potentially unstable materials and heavy components.

For this reason, chimney-stack repairs are generally not suitable DIY jobs.

Even apparently minor work such as repointing can require safe access to roof level and working around potentially deteriorated masonry.

Ground-level maintenance may be manageable yourself, but if the repair requires roof or chimney access, hiring someone with suitable equipment is the safer approach.

Chimney Repair vs Rebuild

Repair may be suitable for local mortar deterioration, individual damaged bricks, flashing, flaunching and pots or cowls.

On the other hand, rebuilding may be considered where deterioration is extensive or structural stability is affected.

A partial rebuild may involve replacing the upper section of the stack while retaining sound masonry below. A complete rebuild involves dismantling and reconstructing substantially more of the chimney and will therefore cost considerably more.

Chimney Repair vs Removal Cost

Consider where an unused chimney is in poor condition, and the homeowner is deciding whether to repair or remove it.

Minor chimney repair work can cost around £150-£300, while substantial repairs or rebuilding can cost considerably more.

Partial chimney removal usually costs considerably more than a basic repair, while a full chimney removal may cost around £4,000-£6,000, depending on the property and extent of the work.

However, repair and removal aren't directly interchangeable. Structural considerations, Building Regulations and the effect on the remaining chimney structure all need to be considered before removal.

Does Home Insurance Cover Chimney Repairs?

Standard home insurance policies may cover chimney repairs when damage has resulted from an insured event such as a fire, storm or impact.

Whether you're covered depends entirely on the terms and exclusions of your policy.

Damage caused by gradual deterioration, poor maintenance or general wear and tear is commonly treated differently from sudden insured damage.

If you're considering making a claim, check the wording of your policy and contact your insurer before arranging non-emergency work.

How Can I Reduce Chimney Repair Costs?

To reduce chimney repair costs, you’ll want to consider addressing deterioration before it becomes more extensive and combining related chimney repairs where sensible.

Beyond that, comparing several quotes is also worth considering as a way to understand the going rate in your area and find a contractor who offers good value for money.

Other things to consider include:

• Establishing whether scaffolding is included in the quote.
• Checking exactly which parts of the stack are being repaired.
• Combining related chimney and roof repairs where appropriate.
• Asking whether materials and waste disposal are included.
• Comparing the same scope of work across each quote.

It’s important to never cut costs by avoiding necessary safe access arrangements.

Roof repair costs can come to around £200-£1,000, depending on the work required.

What Does a Chimney Repair Quote Include?

A chimney repair quote may include:

• Labour
• Materials
• Repointing
• Replacement bricks
• Flashing
• Flaunching
• Chimney pots or cowls
• Scaffolding and access
• Waste disposal
• Related roof repairs
• VAT, where applicable

The exact inclusions depend on the repair, so it’s worth noting that scaffolding may be quoted separately from the chimney work itself.

When seeking a chimney repair quote, you’ll want to secure quotes from several local contractors before deciding who to hire.
