Chimney Repointing Cost

Chimney repointing is an important repair that helps keep a chimney stack stable, weatherproof and safe. It’s often needed on older UK homes where the mortar between the bricks has started to crack, crumble or wash away after years of exposure to wind, rain, frost and heat.

During chimney repointing, the damaged mortar is carefully removed and replaced with fresh mortar to strengthen the brickwork and help stop water from getting into the structure. Many homeowners arrange this work after noticing loose mortar, visible gaps, damp patches near the chimney breast or signs of movement in the stack.

The total chimney repointing cost will depend on the height and size of the chimney, the amount of repointing needed, the condition of the brickwork, access requirements and whether scaffolding or extra chimney repairs are required.

In this guide, we’ll explain how much chimney repointing costs, what affects the price, what the work involves and what to look for when hiring a roofer, bricklayer or chimney repair specialist.

How Much is Chimney Repointing?

The cost of repointing a chimney can vary a lot depending on the size and the condition of the stack. If you only need a small amount of repointing on an accessible chimney, this should cost around £200-£350, while you could pay up to £1,200 on a bigger or more weathered chimney.

If you have a more complex project like a chimney with damaged bricks, failing lead flashing or deteriorated flaunching, the overall chimney repointing cost could fall between £1,000 and £1,800, or possibly more.

Prices for repointing can rise when the chimney is hard to reach. Many homes need scaffolding, and this can add £300-£600 to what you pay. Labour rates can vary a lot across the UK, with prices in London likely to be significantly higher than in the north of the country.

If you've got deeply eroded mortar joints or your chimney has been neglected for a long time, you can expect the job to take longer and need more materials.

You might need to think about having other repairs carried out at the same time, which can increase the full cost of repointing a chimney. Extras like replacing damaged bricks, fixing lead flashing, installing new chimney pots, and repairing flaunching are only identified as necessary once the work has started.

This is because a lot of hidden issues are discovered when the old mortar is removed.

Chimney Repointing Prices

Here's a practical pricing table showing you the most common chimney repointing scenarios and related costs.

These figures reflect current typical UK homeowner costs and are based on national averages from roofing and building contractors.

Supply Costs for Chimney Repointing

The supply-only costs for chimney repointing are quite modest compared to the labour, although it's very important that this work is only ever carried out by experienced professionals for safety reasons.

Common chimney repointing materials include:

• Mortar mix (sand, cement or lime): £10-£25 per bag
• Replacement bricks: £1-£3 each for standard bricks, £3-£6 for reclaimed or matching bricks
• Lead for flashing repairs: £20-£40 per small section
• Flaunching materials (sand, cement, additives): £10-£20
• Protective sheeting and dust control materials: £5-£15
• Waste bags and disposal materials: £5-£10

Some older properties need lime mortar, which is more expensive and will take longer to apply. The overall cost of your project may also rise if you need to match bricks for a period home, especially if the chimney needs several replacements.

Additional Costs of Chimney Repointing

Chimney repointing often means finding extra issues that need to be dealt with. If you are planning on having this work carried out, we recommend that you budget for these possible expenses.

• Scaffolding hire: this is essential for tall or awkward chimneys
• Waste removal: disposing of old mortar and damaged materials
• Brick replacement: vital if your bricks are cracked or spalled
• Chimney pot repairs or replacement
• Lead flashing replacement: commonly needed where water has been leaking
• Flaunching repairs: rebuilding the mortar around the pots
• Cowl installation: improving ventilation or preventing downdrafts
• Roof tile repairs: fixing tiles that have been disturbed during access

Hidden issues like loose bricks, internal damp, leaning stacks and cracked masonry often only become visible after the old mortar has been removed. This can mean paying more to cover the cost of your work; however, it’s usually essential so you can avoid further costly damage later on.

Labour Costs and Timescales for Chimney Repointing

Labour has a massive influence on the overall cost, as this kind of work is carried out at height by tradespeople with valuable specialist skills. Roofers, bricklayers, stonemasons and chimney repair specialists usually charge £150-£250 per day or more. Their rates depend on things like how much experience they have and where they're based.

Many smaller repointing jobs can be finished within just a few hours, although a full chimney stack can take up to two days. Some jobs can take longer if you need brick replacement services, flashing repairs and flaunching work.

Bad weather can also make the job take longer as the tradespeople won't be able to apply mortar during heavy rain or freezing temperatures.

Access can have a big influence on the final price, too. Although it might be possible to reach a simple bungalow chimney with ladders or a small access tower, you might have to pay to have full scaffolding installed if you have a tall chimney on a terraced or detached house.

Cost Factors for Chimney Repointing

Several factors influence the total cost of repointing a chimney:

• Size and height of the chimney: larger stacks require more time and materials
• Extent of mortar deterioration: deeper erosion will mean more preparation
• Ease of access: Difficult chimneys that are hard to reach normally need scaffolding
• Condition of the brickwork: damaged bricks usually mean higher labour and material costs
• Property type: terraced homes may need additional access solutions
• Regional labour rates: costs are higher in London and the Southeast
• Mortar type: lime mortar is more expensive and takes longer to apply
• Additional repairs: these can include flashing, pots, flaunching and brickwork
• Structural issues: leaning stacks or internal damp problems can cost more

Don't be tempted by a cheap fix, as your repair work won't last for long if you ignore deeper issues. If preparation and repair work are carried out properly, your chimney should stay safe and weatherproof for many years to come.

Building Regulations for Chimney Repointing

You don't normally need to get building regulations approval for chimney repointing, as it's usually treated as like-for-like maintenance. However, this isn't always the case, and you might still need to get approval from your local council if you need to rebuild part of the chimney, alter its height or replace structural elements.

You might also have extra restrictions if your home is a listed building or if it's in a conservation area. If you're not sure about whether you need approval or not, ask your local authority before you start the work.

Types of Chimney Repointing

There are several types of chimney repointing, with each intended to resolve different problems.

Spot repointing means making small repairs to isolated areas, while partial repointing usually means repointing one or two sides of the chimney. All sides of the chimney are repointed during full chimney stack repointing, and this is to achieve as much durability as possible.

Lime mortar repointing is essential if you've got an older or heritage property, while repointing with brick replacements lets you combine mortar renewal with structural repairs.

Each of these influences the final price, and full repointing and lime mortar work will cost more because of the time and skill they need.

Alternative Types of Chimney Repair

Repointing isn't always the right solution for every situation. Some other options can be used instead of or alongside repointing, for example, chimney rebuilds, which are needed when the structure is unstable. Flashing repairs replace the mortar around your chimney pots, while lead flashing repairs fix leaks around the base of the chimney.

Chimney pot replacements can improve safety and ventilation, while some chimneys need to be removed completely because they are unsafe or just not needed anymore.

Some of these alternatives cost more and create more disruption than others. Repointing is normally the best option when the mortar has deteriorated, but the structure is sound. More extensive repairs are usually needed when the chimney has started leaning, is cracked or extremely weathered.

Hiring Contractors Checklist for Chimney Repointing

We recommend that you follow a clear checklist when you're hiring a contractor:

• Check they have enough experience with chimney and roofing work
• Ask for examples of their previous projects
• Confirm they have insurance and safety qualifications
• Ask for a detailed written quote
• Make sure scaffolding and waste removal are included if you need them
• Ask if brick replacement or flashing repair services are extra
• Confirm how long the repair work is likely to last

Don't just choose a contractor based on price alone. A clear quote will help you avoid unexpected costs once the work starts.

Removing Old Mortar Before Repointing

Removing the old mortar is essential if you want your repair to last for a long time. During this process, the damaged mortar is raked out, the joints are cleaned, and the surface is prepared for new material. This stage can become more expensive if the mortar is really deteriorated or if bricks are damaged during the prep work.

Although finding hidden structural issues can be disappointing, it’s important to address these problems as soon as you can so you can stop further damage and make sure the chimney stays safe.
