Seeing different coloured bricks on your house can be frustrating, especially when it affects kerb appeal and gives the impression of poor workmanship. Whether the variation comes from repairs, extensions, weathering, or mismatched materials, it is a common issue across UK properties particularly older homes.
The good news is that it can usually be resolved without rebuilding entire walls. With the right approach, you can restore a consistent, natural appearance that blends seamlessly.
Why Houses End Up with Different Coloured Bricks
Understanding the root cause is essential before deciding on the best solution. Brick colour variation rarely happens without reason.
Common Causes of Colour Differences
| Cause | Description | Typical Result |
|---|---|---|
| Extensions | New bricks differ from original materials | Sharp contrast |
| Repairs | Replacement bricks don’t match aged ones | Patchy sections |
| Weathering | Sun, rain, and pollution alter colour over time | Faded or darkened areas |
| Cleaning | Pressure washing or chemicals remove surface tone | Uneven finish |
| Brick batches | Slight variation between manufacturing runs | Subtle inconsistency |
Even if you source “matching” bricks, natural ageing means older bricks will almost always look different.
Step 1: Identify the Type of Mismatch
Not all mismatched brickwork is the same. Some issues are minor and cosmetic, while others are more noticeable and require professional treatment.
Types of Brick Colour Variation
| Type | Severity | Recommended Action |
|---|---|---|
| Slight tone difference | Low | Cleaning or blending |
| Patch repairs | Medium | Brick tinting |
| Extension mismatch | Medium–High | Tinting + blending |
| Completely different bricks | High | Replacement + tinting |
A careful inspection helps determine whether you need a simple fix or a more advanced solution.
Step 2: Clean the Brickwork Properly
Before making any changes, always start with cleaning. Dirt and staining can exaggerate differences in colour.
Effective Cleaning Methods
- Gentle pressure washing
- Soft brushing with mild detergent
- Avoiding harsh acids or sandblasting
Cleaning can sometimes reduce the contrast enough that no further work is needed.
However, over-cleaning can strip the natural patina from older bricks, making them look lighter than surrounding areas.
Step 3: Consider Brick Tinting
One of the most effective ways to deal with different coloured bricks is brick tinting.

What Is Brick Tinting?
Brick tinting is a specialist technique that adjusts the colour of bricks using breathable pigments. Unlike paint, it soaks into the brick and maintains a natural finish.
Benefits of Brick Tinting
- Creates a consistent appearance
- Retains the natural texture of bricks
- Long-lasting and weather-resistant
- Cost-effective compared to rebuilding
Where It Works Best
| Situation | Effectiveness |
|---|---|
| Small repair patches | Excellent |
| Extensions | Very high |
| Faded brickwork | High |
| Severe mismatch | Moderate (may need blending) |
Tinting is often the preferred solution because it allows precise colour matching without replacing bricks.
Step 4: Address Mortar Colour Differences
Brick colour isn’t the only factor mortar plays a major role in how a wall looks.
If the mortar is a different shade, it can make bricks appear mismatched even when they are similar.
Mortar Issues to Look For
- Bright or overly dark joints
- Inconsistent repointing sections
- Modern cement mortar on older properties
Mortar Solutions
| Method | Purpose | Cost Range |
|---|---|---|
| Repointing | Replace mismatched mortar | £40–£80 per m² |
| Mortar tinting | Adjust existing colour | £10–£30 per m² |
| Blending | Subtle visual correction | £5–£15 per m² |
Correcting mortar colour can dramatically improve overall uniformity.
Step 5: Blend the Brickwork
In many cases, the goal is not to make every brick identical but to create a natural, blended look.
Blending Techniques
- Light tinting across a wider area
- Gradual colour transitions
- Introducing slight variation for realism
Professional blending avoids the “patch effect” where one section stands out too clearly.
Step 6: Replace Bricks Where Necessary
If the colour difference is extreme, some bricks may need to be replaced.
When Replacement Is Required
- Completely different brick type
- Incorrect size or texture
- Damaged or poor-quality bricks
Replacement Process
- Carefully remove mismatched bricks
- Source reclaimed or similar bricks
- Install using appropriate mortar
- Blend with surrounding brickwork
Typical Costs in the UK
| Work Type | Estimated Cost |
|---|---|
| Single brick replacement | £50–£150 |
| Small section repair | £300–£1,000 |
| Larger rebuild | £1,500+ |
Reclaimed bricks often provide a closer match than new ones because they have already aged.
Step 7: Avoid Painting the Bricks
Painting may seem like a quick solution, but it often causes more problems than it solves.
Problems with Painting
- Traps moisture inside the wall
- Peels and flakes over time
- Covers natural brick texture
- Requires ongoing maintenance
Instead, breathable solutions like tinting are far more suitable for long-term results.
Step 8: Understand Colour Matching Factors
Matching brick colour involves more than just choosing the right shade.
Key Factors
| Factor | Why It Matters |
|---|---|
| Colour tone | Most visible difference |
| Texture | Affects how light reflects |
| Age | Older bricks have patina |
| Finish | Smooth vs rough surfaces |
Even if colours are similar, differences in texture or finish can still make repairs noticeable.
Step 9: Test Before Full Application
Before committing to any treatment, always test it first.
Testing Checklist
- Apply to a small, hidden area
- Let it fully dry
- Check in different lighting conditions
- Adjust as necessary
Brick colour can appear different depending on weather and light, so testing prevents mistakes.
Step 10: Budgeting for Fixing Different Coloured Bricks
Costs vary depending on the extent of the issue and the chosen solution.
Cost Overview
| Solution | Cost Range | Best For |
|---|---|---|
| Cleaning | £100–£300 | Minor variation |
| Brick tinting | £300–£1,500 | Most mismatches |
| Repointing | £500–£2,000 | Mortar issues |
| Brick replacement | £300–£3,000+ | Severe differences |
Tinting is often the most cost-effective option when compared to full replacement.
Common Mistakes to Avoid
When dealing with different coloured bricks, certain mistakes can make the problem worse.
- Using paint instead of breathable solutions
- Ignoring mortar colour differences
- Over-cleaning older bricks
- Skipping colour testing
- Choosing the wrong brick type
Attention to detail is essential for achieving a natural finish.
When Professional Help Is Needed
While some minor fixes can be handled yourself, professional expertise is often required for visible or complex areas.
Consider a Specialist If
- The mismatch is on the front of the property
- The building is older or historically significant
- Large areas are affected
- Colour matching needs precision
Specialists can replicate subtle tones and variations that are difficult to achieve without experience.
Improving the Overall Appearance of Your Home
Different coloured bricks don’t just affect aesthetics they can also impact perceived property value.
By addressing the issue properly, you can:
- Restore a uniform appearance
- Enhance kerb appeal
- Increase buyer confidence
- Protect the character of the building
A well-blended finish ensures that repairs and extensions look intentional rather than obvious.
Practical Example: Choosing the Right Approach
| Scenario | Best Solution |
|---|---|
| Small repair patch stands out | Localised tinting |
| Extension doesn’t match original house | Full wall blending |
| Mortar is too bright | Repointing or tinting |
| Bricks are completely different | Replacement + tinting |
Each situation requires a tailored approach rather than a one-size-fits-all fix.
Long-Term Maintenance Tips
Once you’ve corrected the colour mismatch, maintaining the appearance is important.
- Avoid harsh cleaning methods
- Inspect brickwork annually
- Repair damage early
- Keep mortar in good condition
Proper maintenance ensures the finish remains consistent for years.
