Repointing Cost Guide 2025: What to Budget for Your London Property
The exterior brickwork of your London property is constantly exposed to the elements. Over time, the mortar joints between the bricks can decay, crack, or crumble. This not only detracts from the appearance of your home or business but can also lead to more serious issues like damp penetration and structural instability. Repointing is the process of renewing these external parts of mortar joints, and it’s a crucial maintenance task to protect your investment.

What is Repointing?
Repointing is the process of removing the weathered and damaged mortar from the joints between bricks or stones and replacing it with new mortar. When done correctly, it provides a weather-tight seal, restores the structural integrity of the wall, and improves its overall appearance.
Factors Affecting Repointing Costs in London
Several factors can influence the final cost of your repointing project:
- Extent of Work & Area Size: The total square meterage to be repointed is a primary cost driver. A single wall will cost less than the entire property.
- Condition of Existing Mortar & Brickwork: If the old mortar is particularly hard to remove or if bricks are damaged and need replacing (£15-£30+ per brick in London), costs will increase.
- Type of Mortar:
- Cement Mortar: Cheaper and quicker to set, often used on modern properties.
- Lime Mortar: More expensive, breathable, and flexible. Essential for older buildings (Victorian, Edwardian etc.) to prevent damage to softer bricks and allow moisture to escape. Using the wrong mortar can cause significant long-term damage.
- Type of Pointing Style: Different pointing styles require varying levels of skill and time:
- Flush Pointing: Mortar is finished flush with the brick face. Most common and generally most cost-effective.
- Recessed Pointing: Mortar is set back slightly from the brick face. Creates a shadow line.
- Weatherstruck Pointing: Mortar is sloped to shed water. More time-consuming.
- Tuck Pointing: A specialist technique creating fine, raised white lines (putty) within a coloured mortar joint, often used on period properties. This is significantly more expensive due to the skill involved.
- Accessibility & Height: Higher walls or hard-to-reach areas (like chimneys or walls over conservatories) will require scaffolding, which is a major cost component. Limited access in dense Central London areas can also increase labour time.
- Scaffolding: Essential for safety and access on multi-storey properties. Costs vary based on the size of the scaffold, duration of hire, and permits if on a public highway (common in London).
- Waste Disposal: Removing old mortar and any debris will require skip hire or other waste disposal methods, which have associated costs, including potential permit fees in London boroughs.
- Location (London Weighting): Labour rates and operational costs are generally higher in London, including Kensington and Chelsea, Westminster, and Hammersmith, compared to other parts of the UK. Parking and congestion charges can also add to the cost for tradespeople.
- Raking Out: The process of removing the old mortar. This can be done manually (hammer and chisel) or with power tools. The depth and hardness of the old mortar will affect the time and cost.
- Protection & Clean-up: Protecting windows, doors, and surrounding areas, plus the final clean-up, should be factored in by the contractor.

Additional Costs to Consider
- Scaffolding Hire: As mentioned, a significant cost. Ensure your quote specifies if this is included or separate. In London, permits for scaffolding on public land are often required and add to the cost.
- Skip Hire/Waste Disposal: Prices in London vary by borough. For example, an 8-yard skip might cost £280-£380+ in areas like Westminster or Kensington.
- Brick Replacement: If bricks are spalled (flaking) or damaged, they’ll need replacing.
- Structural Repairs: If repointing reveals deeper structural issues, these will be an additional cost.
- Cleaning: Brick cleaning (e.g., to remove paint or heavy soiling) before repointing might be recommended and will be an extra charge.
- Fungicidal Wash: May be needed if there’s organic growth on the walls.
- Permits: Besides scaffolding, other permits might be needed for skips or if your property is listed or in a conservation area in London. This is a crucial check in boroughs like Kensington and Chelsea or Westminster.
Why is Repointing Necessary? The Benefits
Investing in timely repointing offers several key benefits:
- Weather Protection: Properly pointed joints prevent water penetration, which is a leading cause of damp, frost damage (spalling), and internal mould growth.
- Structural Integrity: Sound mortar is crucial for the overall stability of your brickwork. Deteriorated mortar can lead to loose bricks and, in severe cases, wall failure.
- Improved Aesthetics: Fresh pointing dramatically improves the look of your property, enhancing its kerb appeal and potentially its value.
- Increased Property Value: Well-maintained brickwork is a positive feature for potential buyers.
- Prevents Pest Infestations: Gaps in mortar can provide entry points for insects and other pests.
- Energy Efficiency: By sealing gaps, repointing can help reduce draughts and improve the thermal performance of your walls slightly.
- Long-Term Cost Savings: Addressing pointing issues early prevents more extensive and costly damage down the line.
How Do I Know if My Property Needs Repointing?
Look out for these tell-tale signs:
- Crumbling or Sandy Mortar: If you can easily scrape mortar away with your finger or a key.
- Cracked Mortar: Visible cracks, especially horizontal ones, in the mortar joints.
- Gaps or Missing Mortar: Sections where mortar has fallen out completely.
- Damp Patches on Interior Walls: This could indicate water ingress through faulty pointing.
- Loose Bricks: If bricks can be wobbled or moved.
- Efflorescence: White, powdery deposits on the brick face, which can indicate moisture movement.
Generally, well-pointed brickwork can last 30-50 years or more, but this depends on the original workmanship, materials used, and exposure to weather. Properties in exposed Central London locations might need attention sooner.
Repointing FAQs
Q: How long does repointing take? A: This depends on the size of the area, the condition of the existing mortar, and access. A single wall on a terraced house might take 3-7 days. A full semi-detached house could take 2-4 weeks.
Q: Can I DIY repointing? A: While it’s possible for small, accessible areas if you have the skills, repointing larger areas or entire properties is a skilled job best left to professionals. Incorrectly done repointing can cause more damage and look unsightly. Professionals have the right tools, experience with different mortar types, and can work safely at height.
Q: What’s the best time of year to repoint? A: Spring and summer are generally best, as drier, milder weather is needed for the mortar to cure properly. Avoid repointing in freezing temperatures or very wet conditions.
Q: How is repointing done? A: The general process involves: 1. Preparation: Protecting surrounding areas and erecting scaffolding if needed. 2. Raking Out: Removing the old, damaged mortar to a suitable depth (usually at least twice the joint width). 3. Cleaning: Brushing out dust and debris from the joints and sometimes washing the wall. 4. Mixing Mortar: Preparing the new mortar to the correct consistency and type for the property. 5. Applying New Mortar: Pressing the new mortar firmly into the joints. 6. Finishing/Tooling: Creating the desired pointing style (e.g., flush, recessed) as the mortar begins to set. 7. Curing: Allowing the new mortar to cure properly.
Q: Do I need planning permission for repointing in London? A: Generally, repointing is considered maintenance and doesn’t require planning permission. However, if your property is a Listed Building or in a Conservation Area (common in Kensington and Chelsea, Westminster, and other parts of Central London), you must consult with your local council’s planning department. There may be restrictions on materials (e.g., requiring lime mortar) and methods to preserve the building’s character. Failure to comply can lead to enforcement action.
