Repointing cost guide

What is repointing?

Mortar holds bricks, stones and blocks together, so it is essential for maintaining your home’s structure, as well as defending against water and damp. If it’s allowed to weaken and get worn down, then the integrity of your home could be at risk.

Repointing is the process of removing and replacing this mortar. It’s an excellent way to fix any damage and wear & tear on your property as well as to improve the look of a home. It’s especially good for older homes, where new mortar can be used to reduce damp and improve the durability of the walls for all weather conditions.

How much does repointing brick walls cost?

As you’d expect, the size of your wall and the number of walls to be completed affects the cost. As a general rule of thumb, the repointing price per m2 is around £45-£55 including clean up.

For a breakdown of each cost we spoke to the online estimators at My Build Estimate – a professional estimating company monitored by the Royal Institute of Chartered Surveyors (RICS). This guide features the estimated average repointing costs they provided.

How do I know if my walls need repointing?

Mortar erodes over time as a result of extreme weather, so all homes will need repointing eventually, although a good quality job can last over 50 years. Telltale signs you need to repoint your walls include soft and crumbly mortar, wet bricks, damaged brickwork and holes in the mortar.

If you discover a white powdery coating appearing on your bricks, known as “efflorescence” this can often be fixed through repointing.

If in doubt a surveyor can confirm the quality of your mortar and any changes needed.

The steps involved in repointing

  1. Check the weather forecast. If it’s raining or below freezing, then any repointing work should be postponed.
  2. Find troublesome areas that need replacing.
  3. Cover the ground. Then clean the wall and remove any plants.
  4. Remove current mortar from top to bottom (this is also known as raking out).
  5. Spray wall with water to stop the mortar drying too quickly and cracking.
  6. Prepare mortar so it matches the existing colour and is the correct strength.
  7. Apply new mortar into gaps, taking special care to fill all gaps and any air pockets.
  8. Remove the excess with a wire brush and smooth everything out.

How long does repointing take?

The time it will take to repoint your wall depends on the size of the area, the damage to existing brickwork/mortar and the type of pointing style you’d like. We cover these areas in more detail below, but in essence, it could take as little as a day to do a small section of wall and seven days or more to do an entire house.

Repointing brickworkWhat affects the cost of repointing?

Raking out: Unless you’re just touching up small areas you will need to rake out the existing mortar. This process involves using power tools or a hammer and chisel to take out a section of the old mortar, usually to a depth of at least 15 mm. Raking out costs around £35 – £45 per square metre.

The condition of the masonry: If there are extensive issues with your brickwork this will result in the bricks needing to be repaired or replaced as well. This could be due to damp or bricks being chipped away over time. These cracks can be repaired through brickwork stitching, so not all bricks have to be replaced.

Materials: For older buildings, lime-based mortar is recommended, whilst for more modern buildings cement-based mortar should be used. Lime mortar is slightly more expensive.

Scaffolding and accessibility: For upper floors and roofs scaffolding or mobile work platforms will be required. This generally costs between £40-£150 per day. Whilst the scaffolding is up this can be an excellent opportunity to do other work at the same time (such as replacing roof tiles or repairing chimneys).

Pointing style: Depending on how you’d like the mortar to look and how weatherproof you want it to be, the cost will vary. For example, tuck pointing – which is when the mortar is lined up exactly with the brickwork – is very time consuming and requires a considerable amount of skill. But it’s visually stunning so may be worth the extra time and cost if that’s the style you’d prefer.

Waste disposal: Lastly, any waste needs to be removed from the site, so check if this is included in the cost.

Cost of repointing a house

To repoint an entire home is a considerable job with a large amount of labour, materials and access equipment required. As we’ve shown above the size of the area, the number of accessible walls and condition of brickwork will play a role.

The cost also depends on the number of walls that need to be completed. Here are a few examples:

Repointing a single wall – such as at the front or side of a house – costs £1,500-£2,200.

Repointing a semi-detached modern house costs around £3,500-£4,500.

Repointing a Victorian terraced property costs around £3,000-£4,400.

Repointing a chimneyChimney repointing cost

Because chimneys are so exposed to the elements, they tend to have mortar that needs replacing first. Using a stronger mortar mix doesn’t solve this problem entirely – due to increased risk of cracks – so instead waterproofing is recommended. Waterproof sealants are relatively cheap so add very little to the cost given the extra life they give to your brickwork.

Repointing a chimney costs £500 – £1,000, plus scaffolding hire.

Repointing patio cost

Repointing a patio or driveway stops weeds getting through and fixes cracks in existing mortar. Much like with brick walls, the mortar is removed, the space cleaned and then it is refilled. Usually this is done with a resin or polymeric mortar.

Repointing a patio costs around £10-£20 per m2.

However, if paving slabs are loose and moving around then the patio will likely need to be re-laid, rather than repointed.

Repointing stone wall cost

Where stones have been laid similarly to bricks, then the cost to repoint stone walls is roughly the same as brick walls. However, when stones have a more haphazard layout, such as using rubble stones then the cost will rise due to the increased time it will take to remove the existing mortar to a greater depth and apply new mortar in lines that are not straight.

On average, repointing stone walls costs £80 per m2.

Roof repointing cost

Roof repointing can range from replacing a few tiles, repointing ridge edges and all the way up to replacing entire sections. Much like how mortar holds bricks together in walls, it also holds concrete tiles in place and can need replacing over time.

Repointing a full roof can cost between £500 – £750.

Can I repoint my house myself?

Repointing may sound easy but it’s also not difficult to do a shockingly bad job that leaves your wall looking worse than when you started. From poor quality finishing & cracking, to accidentally filling in vital weep holes and even risks of making moisture and damp problems worse, repointing is no simple job. Get it wrong and you can even lower the value of your home.

Repointing is very time consuming and needs a good eye for detail to be done correctly. As such, we recommend you hire a qualified professional.

Key takeaways for repointing walls, homes and chimneys
