Mismatched bricks on a house can be a real eyesore. Whether you’ve extended your property, repaired damaged sections, or had replacement bricks installed years ago, a patchy appearance can reduce kerb appeal and affect value. Fixing mismatched bricks isn’t just about aesthetics — it’s about blending old brickwork with new so the wall looks consistent and uniform.
This guide outlines typical costs in the UK to fix mismatched bricks. It breaks down what influences price, the methods used to address the problem, what homeowners should expect to pay, and other factors that affect the total bill. It also includes tables to help compare options and realistic cost brackets based on house size and method chosen.

What Are Mismatched Bricks?
Mismatched bricks occur when an area of brickwork differs in colour, texture or size from surrounding bricks. This can happen when:
- A repair is made with bricks from a different batch or supplier.
- An extension uses bricks that don’t match the existing wall.
- Original bricks are no longer available.
- Weathering and ageing have changed the brick colour over time.
The result is visible patches, streaks or sections that clash with the original wall. Many homeowners want a better visual match, especially on front elevations or prominent walls visible from the street.
Why Fixing Mismatched Bricks Costs Vary
Costs vary widely depending on:
- Method used — painting, staining, colour coating, or replacing bricks.
- Size of the mismatch area — small patches cost less than entire walls.
- Brick type and texture — smooth, hand-made, or specialised bricks cost more.
- Condition of existing brickwork — if repairs are needed before fixing, prices rise.
- Accessibility and height — higher walls with scaffolding cost more.
Before choosing a method, homeowners should understand the options and likely prices.
Common Methods to Fix Mismatched Bricks
There are several approaches:
1. Replacing the Bricks
Removing and replacing mismatched bricks with better-matching ones.
Pros
- Best for structural repairs.
- Long-term solution when matching bricks are available.
Cons
- Can be expensive.
- Matching old bricks isn’t always possible.
2. Colour Coating / Brick Sealer
Applying a colour-matched coating over bricks to create uniform colour.
Pros
- Effective where perfect match isn’t possible.
- Blends patches with existing wall.
Cons
- May require professional application.
- Colour can fade over time.
3. Painting the Brickwork
Using masonry paint to cover mismatched bricks.
Pros
- Most cost-effective.
- Wide range of colours.
Cons
- Paint may chip or peel.
- Requires maintenance.
4. Brick Stain / Mineral-Based Finish
Penetrating stain that alters colour while keeping texture.
Pros
- Natural finish.
- Longer-lasting than paint.
Cons
- Higher material cost.
- Specialist application often needed.
Average Cost Ranges: Quick Comparison
| Method | Typical Cost per m² | Best For | Typical Total for 20m² |

| Brick Replacement | £50 – £120 | Structural fixes & perfect match | £1,000 – £2,400 |
| Colour Coating / Sealer | £30 – £80 | Mismatched patches | £600 – £1,600 |
| Painting | £15 – £40 | Budget fix | £300 – £800 |
| Stain/Mineral-Based Finish | £35 – £90 | Natural finish, mid-range solution | £700 – £1,800 |
Costs above are approximate guide prices and include materials and labour. Larger areas, difficult access or specialist bricks may push prices higher.
Detailed Cost Breakdown by Method
Brick Replacement Costs
Replacing bricks to match the surrounding wall is often the most expensive option, especially when old bricks are rare or discontinued. Labour is also higher because each brick must be carefully removed and reset.
Brick Replacement Cost Components
- Labour: £30–£60 per hr
- Bricks: £0.60–£2.50 per brick (specialist or reclaimed can cost more)
- Materials: Mortar, disposal, site setup
Typical Cost Estimate
- Small patch (10–20 bricks): £150–£400
- Medium section (1–5 m²): £400–£1,000
- Larger area (10–20 m²): £1,000–£2,400+
Replacing bricks is worth it where structural integrity matters or when a close match is available. If matching bricks are no longer made, costs can rise as reclaimed bricks are sourced.
Colour Coating / Brick Sealer
Colour coatings or sealers are products designed to penetrate or adhere to the brick surface, masking differences in colour. These are often used where bricks are mismatched but structurally sound.
Cost Factors
- Product quality and longevity.
- Preparation (cleaning, priming).
- Number of coats.
Typical Price Range
- Small patch (up to 5 m²): £200–£500
- Medium section (5–15 m²): £500–£1,200
- Large areas (20+ m²): £1,000–£1,600+
Colour coating often gives a more professional finish than basic paint and can be matched closely to existing brick tones. It’s a popular choice when repainting isn’t wanted.
Masonry Painting
Painting with masonry paint (either by brush or sprayer) is the most straightforward and affordable way to fix mismatched bricks. It’s most effective on smaller sections or where a uniform colour is acceptable.
Painting Cost Breakdown
- Materials: £20–£60 per litre (masonry paint)
- Labour: £15–£30 per m²
- Preparation: Cleaning, minor repairs
Typical Costs
- Small area (5–10 m²): £150–£350
- Medium area (10–20 m²): £300–£800
- Large area (whole wall): £800–£2,000+
Painting is cost-effective, but bricks may need repainting every few years as paint weathers.
Brick Staining / Mineral Finish
Brick stains and mineral-based finishes penetrate the brick surface and permanently alter colour without hiding texture. This provides a natural, long-lasting finish while blending mismatched areas effectively.
Staining Cost Drivers
- Stain quality
- Prep work (cleaning, drying)
- Labour skill level
Price Estimates
- 5–10 m²: £300–£700
- 10–20 m²: £700–£1,500
- 20+ m²: £1,500–£2,500+
Staining is more costly than painting but has better longevity and a less artificial appearance.
Factors That Increase Costs
Several factors push costs above the basic ranges:
1. Size and Height
Larger walls and multi-storey elevations require more materials and labour. Scaffolding or access equipment increases costs.
- Single-storey, ground level: lower end
- Two-storey and above: add 15–50%+
2. Preparation Work
Brick surfaces often need:
- Pressure washing
- Repointing
- Removal of old paint or coatings
Prep work alone can add £200–£800.
3. Matching Old Bricks
Finding matching bricks can involve:
- Buying reclaimed bricks
- Custom sourcing
- Testing samples
This adds material costs and time.
4. Weather Conditions
External work is weather-dependent. Delays due to rain or cold, or needing weatherproofing can extend project time.
Choosing the Right Approach
Choosing the best solution depends on goals and budget:
| Budget Level | Best Approach | Why |
|---|---|---|
| Low | Painting | Cheapest overall |
| Mid | Colour coating / stain | Better finish, longer lasting than paint |
| High | Brick replacement | Best match and structural solution |
| Aesthetic focus | Staining or mineral finish | Natural look, retains texture |
A Worked Example
Imagine a home with a 10 m² patch of mismatched brick on the front wall. You have three options:
Option A: Painting
- Preparation: £250
- Paint & materials: £150
- Labour (15 m² at £20/m²): £300
Total: ~£700
Option B: Colour Coating / Sealer
- Preparation: £300
- Product & materials: £300
- Labour (15 m² at £35/m²): £525
Total: ~£1,125
Option C: Brick Replacement
- Bricks: £150 (20–30 reclaimed bricks)
- Labour (5 hrs at £40/hr): £200
- Repointing & finishing: £150
Total: ~£500
In this scenario, direct replacement is cheapest — but only because matching bricks were available easily. If bricks were rare and needed sourcing, the replacement cost could rise above coating or staining.
Professional vs DIY
Fixing mismatched bricks yourself can reduce labour costs, but there are risks:
DIY pros
- Lower labour costs
- Flexible timing
DIY cons
- Matching colour and finish can be harder
- Lack of experience may lead to uneven application
- Safety concerns with working at height
For complex jobs, especially those requiring precise colour matching or coatings, professional help is recommended.
Maintenance Costs Over Time
After fixing mismatched bricks, some maintenance is needed:
| Method | Expected Durability | Maintenance Notes |
|---|---|---|
| Painting | 3–7 years | Repainting may be needed sooner if exposed to sun |
| Colour coating / sealer | 7–12 years | Occasional touch-ups, recoat as needed |
| Staining / mineral finish | 10–15 years | Lowest maintenance |
| Brick replacement | 25+ years | No colour work needed if match is perfect |
Lifetime costs should be considered. Cheaper fixes may cost more in repaint cycles over decades.
Value Added to Property
Fixing mismatched bricks doesn’t just improve appearance. It can:
- Increase resale appeal
- Improve perceived quality
- Help protect against moisture ingress
Good work can make the house look newer and better cared for.
