Chimneys are exposed to the weather all year round, so it’s not unusual for wear and tear to build up over time.

If you’ve noticed signs of a problem, one of the first questions is usually how much it will cost to put it right. The answer depends on the type of repair needed and how easy the chimney is to access.

Issues can include:

• Cracked mortar

• Loose flashing

• Small leaks

This guide explains the average cost for chimney repair work in the UK, what affects the final price, and when it makes sense to get professional help.

How much does chimney repair cost in the UK?

The average cost for chimney repair in the UK varies quite widely because chimneys can develop very different types of problems.

A simple repair to flashing or mortar might be completed in a day and could start from around £250, while structural work or chimney removal will take longer and could cost up to around £1,800.

Use our table to get an idea of the average cost of common chimney repair jobs in the UK:

Most of the time, the final price depends less on the individual contractor and more on the condition of the chimney itself and whether scaffolding or specialist equipment is needed to complete the repair.

Older chimneys or those that have been leaking for some time usually need more extensive work.

Types of chimney repair and their costs

Chimneys can develop several different types of problems, and the right repair depends on what's gone wrong. Some jobs are routine maintenance, while others involve structural work.

Below, you'll find the most common chimney repairs and the typical costs involved.

Roof tile repair around the chimney

Repairing the roof around the chimney is sometimes necessary to stop leaks or prevent further structural problems.

Roof tiles or flashing around the chimney can become damaged over time, particularly after storms or heavy weather.

• Typical cost of roof tile repair: £170 to £500 (to replace up to five tiles)

The lower end of this cost range is for easily sourced tiles for a job that has no access issues or scaffold requirements.

The higher end of the scale represents the same number of tiles, but those that are harder to source, and where scaffolding is needed.

Our guide to roof tile replacement costs has more information.

Chimney cap installation cost

A chimney cap sits on top of the chimney and helps keep out rain, debris and animals. Installing a cap is often a preventative measure rather than a repair. It can help extend the life of your chimney and reduce the risk of blockages or water damage.

• Typical cost of chimney cap installation: £180 to £520

The cost range represents the supply and fit of a standard chimney cap (£180) and more elaborate models (these can rise to around £520). For more detailed pricing information, take a look at our guide to chimney cap installation costs.

Chimney flashing repair cost

Flashing is the waterproof seal where the chimney meets the roof. When flashing fails, water can seep into the roof space or ceiling. Damaged flashing is one of the most common causes of chimney leaks. In many cases, repairing or replacing the flashing resolves the problem quickly.

• Typical cost of chimney flashing repair: £250 to £1,000

Patch repairs that don’t require scaffolding sit at the lower end of this cost range. Replacing all four sides of chimney flashing, including scaffolding, can take costs up to around £1,000. For more detail, see our guide to chimney lead flashing repair costs.

Chimney repointing cost

Repointing involves replacing worn or damaged mortar between bricks. It's one of the most common chimney repairs, especially on older properties. Repointing helps keep the chimney stable and prevents water from entering the brickwork. If mortar joints start to crumble or fall out, it is usually a sign that repointing is needed.

• Typical cost of chimney repointing: £300 to £1,000

The cost of chimney repointing is largely determined by its size and ease of access.

For example, repointing a small chimney on a low-level roof might cost around £300, climbing to around £1,000 to repoint a chimney in the middle of a semi-detached house (with scaffolding over the ridge).

You can read more in our dedicated guide to chimney repointing costs.

Chimney removal cost

Chimney removal is usually carried out when a chimney is no longer needed or has become structurally unsafe.

• Typical cost of removing a chimney stack: £260–£340 per metre (or around £1,800 as a total project cost)

The cost depends on whether the entire chimney is removed or just the stack above the roofline. The costs above represent chimney stack removal, leaving the chimney breast inside the property intact.

Structural support and waste removal can also affect the final price you're quoted. You can explore the full breakdown, including the cost of removing a chimney breast, in our guide to chimney removal costs.

What affects the cost of chimney repair?

Several factors can influence how much chimney repair work is likely to cost.

The main ones include:

• Type of repair: Simple maintenance jobs usually cost less than structural repairs or chimney removal

• Height of the chimney: Taller chimneys take longer to reach and may require additional safety measures

• Condition of the chimney: Minor damage is usually quicker to fix than widespread deterioration

• Access to the property: Limited access can make it harder to set up equipment or carry out repairs safely

• Location: Labour costs vary across the UK, particularly between urban and rural areas

• Scaffolding requirements: Working at height often requires scaffolding, which can add significantly to the overall cost of chimney repair

On Checkatrade, you'll only find trades who meet our high standards and pass up to 12 checks.

Additional costs to budget for

The repair itself is usually the main expense, but there can sometimes be additional work needed once the chimney has been inspected.

Common additional costs to be aware of include:

• Debris removal or waste disposal

• Repairs to surrounding roof tiles

• Replacement chimney liners

• Structural repairs to brickwork

• Internal repairs caused by water damage

• Emergency or out-of-hours callouts

Not every job will involve these costs, but it's sensible to allow for them when planning your budget.

What should be included in a chimney repair quote?

A clear written quote helps you understand exactly what work is being carried out and what you're paying for. This is particularly important for roof or chimney work, where you can't always see clearly for yourself what's happening up there.

A typical chimney repair quote should include:

• Inspection of the chimney and roof

• A description of the repair work

• Details of materials being used

• Labour costs

• Access requirements such as scaffolding

• Waste removal and clean-up

• Confirmation of the total cost

Comparing quotes from more than one contractor can help you understand what a fair price looks like for your property.

We check the reviews on Checkatrade are from real people, and that trades meet our high standards.

How long does chimney repair take?

The time needed to repair a chimney depends on the type of work involved and the condition of the structure.

As a general guide:

• Minor repairs can often be completed in a single day

• Repointing or flashing repairs may take one to three days

• Major structural repairs or removal can take several days or longer

Bear in mind that weather conditions can also affect the schedule, particularly for roof-level work.
