Chimney Repointing and Repair Cost UK (2026)

Chimney repointing cost in the UK is typically £400 to £1,200, with most homeowners paying around £750. The figure varies a lot because so much of the price is not the pointing itself but the scaffolding and access needed to reach the stack safely. This guide breaks down what you should expect to pay in 2026, what pushes the cost up, and how repointing compares with the bigger jobs of rebuilding a stack or renewing the flashing, so you can judge a quote before you accept it.

Repointing means raking out the old, failed mortar between the bricks and replacing it with fresh mortar. On a chimney it is one of the most common repairs, because the stack is the most exposed masonry on the whole house and the first place mortar erodes.

Chimney repointing cost by property

The single biggest factor is how high and how accessible the chimney is:

• Bungalow or easy access: from around £400, where a tower scaffold or safe roof access is enough.
• Standard two-storey house: commonly £600 to £900, once proper scaffolding to the ridge is included.
• Period property in lime mortar: £700 to £1,200, as lime pointing is slower, skilled work and the correct match for older or listed buildings.

Larger homes with high ridges, three storeys, or awkward access can run beyond £1,200 simply because the scaffold is more complex. As a rule of thumb, London and the South East sit 10 to 20% above the national average because of higher labour rates.

Why scaffolding drives the price

On many chimney jobs, scaffolding is the largest single line on the invoice, often £400 to £1,200 on its own depending on height, duration and access. That is why a small amount of actual pointing can still cost several hundred pounds: you are paying to reach it safely and legally.

This also means it is worth bundling work. If the scaffold is going up anyway, having the flashing checked, a pot re-bedded or the stack re-rendered at the same time spreads that fixed cost across more work. Our roof scaffolding cost guide explains the access charges in more detail.

The mortar itself

The pointing rate is broadly the same as ordinary wall repointing: roughly £40 to £60 per square metre in a cement-based mortar, or £60 to £90 per square metre in lime. A chimney stack is a small area, so the mortar cost is minor next to access, but the choice of mortar matters. Older and solid-wall properties usually need a lime mortar so the masonry can breathe; using a hard cement mortar on soft period brick can trap moisture and cause spalling.

Repointing vs rebuilding a chimney

Repointing only works if the bricks themselves are sound and just the joints have failed. If the brickwork is crumbling, leaning, or the mortar has gone soft all the way through, a rebuild is the honest answer:

• Partial rebuild (replacing a damaged section): typically £600 to £1,000.
• Full rebuild of the stack above the roofline: usually £1,000 to £3,500, depending on size and access.

A good contractor will tell you when repointing is a false economy. If you are being quoted repointing on a stack that is visibly bowing, get a second opinion.

Related chimney repairs

While the scaffold is up, these repairs are often done together:

• Repointing plus flashing renewal. The lead flashing where the chimney meets the roof is a common leak point. See our roof flashing repair cost guide.
• Chimney pot and flaunching. Re-bedding a loose pot or renewing the flaunching (the mortar fillet that holds the pots) is frequently needed alongside pointing.
• Capping or a cowl. If the chimney is redundant, capping it (while keeping ventilation) prevents rain ingress.

How to get an accurate quote

• Get at least two or three written quotes and make sure each states whether scaffolding is included.
• Ask whether they are repointing in cement or lime, and why, for your property type.
• Check the contractor’s insurance and, for work at height, that they will use proper scaffolding rather than ladders alone.

For the rules on working safely at height, the Health and Safety Executive sets out the legal duties, and Historic England publishes guidance on lime mortars for older buildings.

Frequently asked questions

How much does it cost to repoint a chimney in the UK? Chimney repointing typically costs £400 to £1,200, averaging around £750. A bungalow with easy access can start near £400, a standard two-storey house is commonly £600 to £900, and a period chimney repointed in lime is often £700 to £1,200. Scaffolding is usually the largest part of the bill.

Why is chimney repointing so expensive? Most of the cost is access, not the pointing. Reaching the stack safely usually needs scaffolding, which alone can be £400 to £1,200 depending on height and duration. The actual mortar work is a small area, so the fixed cost of getting up there dominates the price.

Is it cheaper to repoint or rebuild a chimney? Repointing is much cheaper if the bricks are sound and only the joints have failed. If the brickwork is crumbling or leaning, a rebuild is needed: a partial rebuild is typically £600 to £1,000 and a full stack rebuild above the roofline £1,000 to £3,500. Repointing failing brickwork is a false economy.

How often does a chimney need repointing? It depends on exposure and the original mortar, but many chimneys need repointing every 20 to 30 years, and sooner on very exposed or coastal properties. Signs it is due include crumbling or missing mortar, damp patches on the chimney breast inside, and loose or leaning brickwork.

Should a chimney be repointed in lime or cement mortar? Older and solid-wall properties usually need a lime mortar so the masonry can breathe, which is also the correct match for period and listed buildings. Cement mortar can trap moisture in soft old brick and cause it to spall, so use the mortar that suits your property rather than defaulting to cement.
