If you’ve noticed crumbling mortar, gaps between bricks, or damp patches on your walls, it may be time to consider repointing. But one of the first questions homeowners ask is:
“How much does repointing cost, and how long will it take?”
In this guide, we’ll break down everything you need to know — including average UK costs, timelines, and what affects the price — so you can plan your project with confidence.
What Is Repointing (And Why Is It Important)?
Repointing is the process of removing old, damaged mortar between bricks and replacing it with fresh mortar. This helps:
- Prevent water ingress and damp
- Strengthen the structure of your home
- Improve kerb appeal
- Extend the lifespan of your brickwork
Well-executed repointing can last 25–50 years, making it a smart long-term investment for your property.
Average Cost of Repointing in Wiltshire
Repointing costs vary depending on access, materials, and wall condition.
Typical UK Prices:
- £50–£60 per m² – standard brick repointing
- £60–£100 per m² – stone or detailed work
- £60–£90 per m² – lime mortar (common in older properties around Bath, Lechlade, Lacock, Melksham Warminster and Devizes for example)
Typical Project Costs:
- Small repair: £300 – £500
- One wall: £1,000 – £2,200
- Full house: £3,000 – £5,000+
In Wiltshire, many period homes require lime mortar, which is more labour-intensive but essential for proper breathability. Cement mortar is fine for newer buildings.
How Long Does Repointing Take?
The timeframe depends on the size of the job and weather conditions.
- Small repair: 1 day
- One wall: 3–7 days
- Full house: 1–3 weeks
A typical semi-detached property in Calne, Wiltshire and surrounding areas is usually completed in around 5–10 working days.
What Affects the Cost?
Several key factors influence pricing:
- Access & Scaffolding: If scaffolding is required, this can add £500–£1,000+
- Mortar Type: Older homes often need lime mortar, which takes longer but prevents damp issues.
- Condition of Brickwork: Heavily deteriorated joints require more preparation.
- Property Age: Wiltshire has many heritage properties that require specialist techniques.
Signs Your Property Needs Repointing
- Crumbling or missing mortar
- Damp patches inside walls

Ignoring these can lead to serious structural and moisture problems.
Is Repointing Worth It?
In short, Yes - Repointing is a cost-effective way to:
- Protect your home from water damage
- Strengthen brickwork

Done properly, it can last 25–50 years.
Is Scaffolding Essential For Repointing?
Scaffolding is often needed for repointing work on upper walls, chimneys, or larger external elevations. For smaller ground-level areas, access equipment may be minimal. It's worth bearing in mind that the need for scaffolding will affect the overall cost.

Frequently Asked Questions About Repointing
How much does repointing a wall cost in the UK?
The cost of repointing a wall in the UK typically ranges from £50 to £60 per square metre for standard brickwork. More specialist work, such as lime mortar or stone repointing, can cost more. The final price depends on the size of the wall, ease of access, mortar type, and the condition of the existing joints.
How long does repointing a wall take?
A small repointing repair may take just one day, while repointing a full wall usually takes 3 to 7 days. Larger projects, such as a full house, can take 1 to 3 weeks, depending on weather, access, and the amount of preparation needed.
How do I know if my wall needs repointing?
Common signs include crumbling mortar, gaps between bricks, damp patches, loose bricks, and visible cracking in the joints. If left untreated, damaged mortar can allow water into the wall and lead to more costly repairs.
Does repointing stop damp?
Repointing can help reduce damp caused by failing mortar joints that let water penetrate external walls. However, damp can have several causes, so it is important to have the property inspected properly to identify the source of the problem.
What is the best mortar for older properties in Wiltshire?
For many older or period properties, lime mortar is often the best option because it allows the building to breathe and helps manage moisture correctly. Using the wrong mortar on an older building can trap moisture and cause damage over time.
