Prices for Repointing Walls and Chimney Stacks

Almost every brick wall in the UK will need to be repointed at some point. The mortar between the bricks doesn’t just hold them in place, it also acts as a barrier to wind, rain and frost.

From a structural point of view, the mortar is just as vital as the bricks themselves.

The importance of the mortar joint shouldn’t be underestimated. Poor quality workmanship can ruin the appearance of the brickwork and can lead to the early failure of the mortar.

While small patches at low levels can be repaired by DIYers with some basic training, higher-level work and projects on older buildings should be completed by a professional.

(The guide on this page assumes you’re working on a modern building with cement-based mortar. If your home is a period building and is constructed with lime-based mortar, you should not use cement. Lime allows the wall to breathe and is typically found on older buildings, cement is watertight and should be used on modern dwellings.)

What is Mortar?

Mortar is a mixture of sand and either cement or builder’s lime and is used between the courses of bricks or blocks on most walls in the UK.

It shouldn’t be confused with concrete.

Mortar should always be weaker and more flexible than the bricks. If the wall experiences any minor movement or stress, it’s important that the mortar flexes too.

If the mortar mix is stronger than the bricks, any stress will be transferred to the bricks and cracks will appear in them, they’ll then need to be replaced.

Why Does Mortar Fail?

As previously stated, the mortar mix should always be weaker than the bricks. This is where issues can creep in.

Most houses shouldn’t require any repairs or mortar renewal work for at least 60 years unless:

  • The original bricklayer used a mix that was far too weak and it has now failed.
  • The existing pointing was too brittle or thin and has now crumbled or cracked.
  • The brickwork is in an exposed location and driving rain has washed out the mortar.
  • Chimneys, due to their exposed location, often require remedial work before any other bricked walls.

What is The Best Mortar Mix For Repointing?

While many tradespeople still use a mixture of sand and cement, this is almost always stronger than the bricks and can lead to problems with cracking in the future.

There is much debate amongst bricklayers and specialists about the “perfect mix” but it really depends on the age and type of bricks on a wall.

For a typical modern house, a mixture of 5 parts sand and one part cement should suffice.

For period properties with very soft bricks, the cement can be omitted completely and replaced with 2 parts of lime.

This page contains a list of suggested mortar mixes for various projects including bricklaying and pointing.


Chimneys are the most exposed part of a property and wind-driven rain can wash out weak mortar mixes leaving the stack in a precarious situation.

The knee jerk reaction of many tradespeople is to use a stronger mortar mix, but as we already know, this can result in cracks and deterioration in the bricks.

One option is to repoint the chimney bricks using a 5 parts sand, one part lime and one part cement mixture and then allow the mortar to fully dry before applying a waterproof sealant to the entire stack.

There are plenty of waterproof sealants available online, the key is to apply them to a fully cured and dry chimney stack. Issues usually arise after the sealant has been brushed onto a wet wall.

Period Buildings

Period properties are often designed to breathe and the bricks are much softer than those seen in modern buildings.

Using a high concentration of cement in the mortar mix is a no-no as it will either crack and fall out or transfer any stress to the bricks that will then crack and spall.

For older buildings with Victorian, Edwardian or Georgian brick facades, a lime mortar mix should be used instead. This type of work should be completed by a specialist and almost always costs more than a sand/cement mortar repoint.

What Steps Are Involved With Repointing?

The hardest part of most repointing projects isn’t the pointing itself but the preparation work.

For most brick walls on modern homes, the existing mortar should be raked out to a depth of around 15-25mm.  For walls with inconsistent mortar strengths, you may need to use a tool such as a chisel or a disc cutter. This can add a considerable amount of time to the project.

The joints should also be free of dust prior to the work commencing.

Here the step-by-step instructions on how to repoint brickwork:

  1. Cover the ground with a tarpaulin
  2. Scrape, rake and/or cut out existing mortar to the wall
  3. Replace any cracked or spalled bricks
  4. Brush down the wall to remove any dust from the courses
  5. Prepare mortar to desired strength and ensure a good colour match (samples are normally created beforehand so you know which colour sand to buy)
  6. Press mortar into joints
  7. Cut off excess mortar and smooth over the mortar with a trowel

Pointing Styles and Finishes

Pointing types and styles for brickwork

Want to use our images or data on your own site or blog? Read this first.

There are many different types of pointing, here are the most common:

Tuck Pointing

tuck pointingThis style requires a very high level of skill and/or experience. A mortar bed is cut and a ribbon of lime putty is precisely trimmed to leave a neat finish that mimics perfectly straight brickwork.


Weatherstruck pointingWeatherstruck is less common these days, this is in part because it’s also a time-consuming project. This is one of the most weather-resistant types of pointing.

Bucket Handle/Concave

bucket pointingThis is one of the most commonly seen styles of pointing, it’s also one of the easiest to achieve (try a tool like this) and has good weather resistance.

Flush Pointing

Flush pointingThis style is best suited to brick walls where you want a rustic finish. It’s easy to achieve but isn’t suitable for all types of bricks.

How Long Does it Take to Repoint a Wall?

It’s almost impossible to predict how long this work will take without first looking at the wall.

Below is a very rough guide but please remember the following points:

  • Soft mortar = easy to rake out.
  • Hard or inconsistent mortar strength = difficult and time-consuming to remove.
  • Different finishes take different amounts of time and require different skill and experience levels.
  • The suggested times below exclude scaffolding and assume flush or standard pointing.

Small chimney – less than one day.

Medium chimney – half a day.

Large chimney – one day minimum.

3-bed semi – one day per side of the property but it really depends on how difficult the preparation work is.

Access Issues

Whether you are planning to repoint the brickwork yourself or get a professional in, a significant expense is the access equipment you’ll need.

If you live in a bungalow, you’ll need nothing more than a stand.

For houses and townhouses, you need either a full scaffold or movable access towers.

Needless to say that a full scaffold system is far more expensive than movable towers and reaching a very high chimney can be costly.

When gathering prices for repointing work, we suggest you shop around as some tradespeople or businesses own towers while others will need to bring in the services of an external scaffold company.

Repointing Cost

Below is our guide to repointing prices in the UK.

The figures are per square metre, except for chimneys, these are priced per stack.

None of the prices below includes the cost of scaffolding, however, as previously stated, many tradespeople have their own access towers which could be used, at least in part, to gain access.

Small chimney£500 - £750
Medium chimney£750 - £1000
Large chimney£1000 - £1250
Repointing to a modern house£30 - £50 per square metre depending on location and overall size of project and complexity
Repointing period property with lime based mortar£65 - £85 per square metre depending on location, overall size of project and complexity
Typical 3 bed house - modern£2500 - £3250
Typical 3 bed house - period property£3500 - £4250

The prices above are based on a property in the south of the UK. Other areas may be slightly cheaper. For projects larger than 75 square metres, the cost per square metre will reduce.

Paul FNuneatonOne wall repointed due to water penetration which caused damp cavity wall insulation and mould on the walls. £800 to remove the wet insulation and £650 to repoint the bricks (no scaffold used, just platforms). PLEASE do not have cavity wall insulation if your external walls allow rainwater in, we've also had to pay for new plasterboard to our internal walls - a very expensive experience. (2021)£650 (one wall)
Heather WBordon, HantsIt cost us £900 to have our long garden wall repointed. It took three days. (2020)£900
