When a new extension is built, one of the most common problems homeowners face is mismatched brickwork. Even when builders try to source similar materials, differences in age, firing methods, weathering, and quarry source often mean the new section stands out sharply against the original house. Brick tinting offers a permanent way to blend the extension so it looks as though it has always been part of the property.
If you are considering professional tinting, understanding the true cost is essential. Prices vary widely depending on the size of the extension, accessibility, brick type, and the complexity of colour matching.

Typical UK Cost for Tinting an Extension
Unlike full-house tinting, extension projects usually involve one or two elevations. Across the UK, the most common price range for tinting extension brickwork is:
- £300 to £1,500 for most domestic extensions
- £15 to £25 per square metre for larger areas
- Up to £30+ per m² for detailed blending work
These figures reflect typical residential jobs and depend heavily on surface area and complexity.
Cost by Extension Size
The size of the extension wall is the single biggest factor in pricing.
| Extension Wall Size | Typical Cost Range |
|---|---|
| Small patch (1–3 m²) | £80 – £300 |
| Small single wall (10–20 m²) | £250 – £500 |
| Medium extension wall (20–30 m²) | £400 – £750 |
| Large rear extension (30–50 m²) | £600 – £1,200 |
| Very large or wraparound extension | £1,200 – £1,800+ |
Smaller jobs often have a higher cost per square metre because setup time and colour matching are fixed costs.
Why Extensions Often Need Tinting
Extensions almost always involve new bricks that differ from the original house in at least one way:
- Different colour tone
- Different texture or finish
- Lack of weathering
- Modern manufacturing methods
- Different mortar colour
- Sun fading on older bricks
Tinting allows technicians to recreate decades of natural ageing within a few hours.
Cost per Square Metre — A Useful Planning Tool
Professionals often price extension work using square metre calculations.
| Type of Tinting | Typical Price per m² |
|---|---|
| Standard tinting | £30 – £50 |
| With preparation | £45 – £75 |
| With scaffolding | £50 – £90 |
| Full elevation blend | £40 – £65 |
Complex blending jobs cost more because each brick may require multiple tones applied by hand.
Real-World Example: Side Extension Blend
Imagine a typical single-storey side extension with one exposed brick wall measuring 12 m².
| Item | Estimated Cost |
|---|---|
| Surface cleaning | £40 |
| Tinting labour & materials | £250 |
| Colour matching | £60 |
| Access equipment | £80 |
| Estimated total | £430 |
This aligns closely with industry examples for blending new extension brickwork.
Factors That Affect Extension Tinting Costs
Every extension is unique. Several variables influence the final price.
1) Surface Area
Larger areas reduce the per-square-metre rate because preparation and colour matching costs are spread out.
2) Height and Access
Even small extensions can require additional equipment.
| Access Situation | Typical Extra Cost |
|---|---|
| Ground level only | Minimal |
| Ladders or tower | £100 – £300 |
| Full scaffolding | £200 – £500 |
Scaffolding is more likely if the extension has two storeys or sits on uneven ground.
3) Colour Matching Complexity
Matching new bricks to aged originals is far more demanding than recolouring a wall uniformly.
| Match Type | Cost Impact |
|---|---|
| Single colour darkening | Base price |
| Multi-tone ageing effect | +10% to +25% |
| Highly detailed blending | +20% to +40% |
Technicians may use multiple pigments to mimic soot staining, mineral deposits, and sun fade.
4) Brick Type and Porosity
Different bricks absorb tint differently:
- Soft clay bricks: easiest and cheapest
- Dense engineering bricks: harder to tint
- Glazed bricks: may require specialist treatment
- Reclaimed bricks: unpredictable absorption
Harder bricks require more labour and product.
5) Mortar Colour Differences
New mortar often looks brighter than original mortar.
| Service | Typical Cost |
|---|---|
| Mortar tinting | £5 – £10 per m² |
| Lime mortar restoration | £15 – £30 per m² |
Tinting mortar can dramatically improve the final result.
Extension Tinting vs Brick Replacement
Some homeowners consider replacing mismatched bricks instead of tinting. This is usually far more expensive.
| Method | Typical Cost | Disruption |
|---|---|---|
| Tinting extension | £300 – £1,500 | Low |
| Partial brick replacement | £1,500 – £3,000 | High |
| Rebuilding wall section | £2,500 – £6,000 | Very high |
Tinting is typically the most cost-effective solution for purely cosmetic issues.
Labour Costs and Time Required
Tinting an extension is relatively quick compared with construction work.
| Project Size | Typical Duration |
|---|---|
| Small patch | 1–2 hours |
| Single extension wall | Half day |
| Large wall | 1 day |
| Multiple elevations | 1–2 days |
Because the work is meticulous and applied brick-by-brick, labour is the main cost component.
Add-On Costs to Budget For
A comprehensive quote may include several additional services:
- Pressure washing or chemical cleaning
- Masking of windows and doors
- Brick repairs
- Efflorescence removal
- Protective sealing
- Waste disposal
- Travel charges (remote areas)
Cleaning alone can cost £2–£4 per m² if the brickwork is dirty.

- Standard colour match
Estimated cost: £350 – £550
Scenario B — Two-Storey Side Extension
- Wall area: 30 m²
- Scaffolding required
- Multi-tone blending
Estimated cost: £800 – £1,300
Scenario C — Large Wraparound Extension
- Wall area: 50 m²
- Complex colour matching
- Multiple elevations
Estimated cost: £1,200 – £1,800+
Why Tinting Costs More Than Painting
Although painting brickwork is cheaper upfront, tinting offers significant advantages.
| Feature | Brick Tinting | Brick Painting |
|---|---|---|
| Breathable | ✅ Yes | ❌ Often no |
| Appearance | Natural | Coated look |
| Lifespan | 25+ years | 5–10 years |
| Maintenance | Minimal | Regular repainting |
| Peeling risk | None | High |
Tint penetrates the brick surface rather than forming a film, allowing moisture to escape.
Long-Term Value of Tinting an Extension
Many homeowners choose tinting because mismatched brickwork can reduce kerb appeal and resale value. Once completed, a well-blended extension:
- Appears original to the property
- Requires little maintenance
- Improves visual harmony
- Preserves the brick’s natural texture
- Can last decades without reapplication
Tinting can also be adjusted later if further building work introduces new brickwork.
When Tinting an Extension Is Most Worthwhile
Professional tinting is particularly useful when:
- Planning restrictions prevent rendering or cladding
- The extension uses modern bricks unavailable in older styles
- Reclaimed bricks still do not match
- Weathering differences are obvious
- You want a seamless architectural appearance
It is often the finishing touch that makes an extension look professionally integrated.
How to Get an Accurate Quote
Specialists usually assess the site in person to evaluate:
- Exact surface area
- Brick condition
- Colour difference severity
- Access requirements
- Environmental exposure
- Need for mortar tinting
Photographs can help but rarely capture subtle colour variations accurately.
Signs of High-Quality Tinting Work
When evaluating quotes, look for:
- Mineral-based breathable pigments
- On-site colour matching
- Sample test patches
- Protection for surrounding surfaces
- Experience with extension blending
- Clear breakdown of costs
Cheap quotes may involve surface coatings rather than true tinting.
DIY Tinting — Is It Suitable for Extensions?
While DIY products exist, extension blending is particularly difficult because the goal is invisibility. Challenges include:
- Matching weathered tones precisely
- Avoiding patchy results
- Achieving consistent absorption
- Working safely at height
Professional work typically produces far more natural results.
Final Thoughts on Extension Brick Tinting Costs
Tinting an extension is one of the most cost-effective ways to correct mismatched brickwork without altering the structure of the building. For most UK homes, the investment is modest compared with the cost of the extension itself, yet the visual improvement can be dramatic.
Prices vary from a few hundred pounds for small blends to over a thousand for large multi-storey extensions, with the exact figure determined by area, access, and colour complexity.
