Brickwork is one of the most enduring and classic exterior finishes for homes across the UK. Yet even the best brickwork can look unattractive over time. Issues such as uneven colouring, damaged mortar, cracked bricks, poor pointing, inappropriate repairs, mismatched bricks, and general wear can make a property’s façade look ugly or neglected.
Fixing ugly brickwork is about both structural repair and aesthetic improvement. This guide walks through common problems, how to diagnose them, practical fixes, and cost considerations — all with a focus on achieving results that enhance your home’s appearance and longevity.
Common Causes of Ugly Brickwork
Before fixing brickwork, it’s important to understand why it may look unattractive in the first place. Typical issues include:
| Problem | Visual Effect | Underlying Cause |
|---|---|---|
| Poor pointing | Gaps, cracks, inconsistent joints | Weathering, inferior mortar mix |
| Cracked or spalled bricks | Broken edges, rough surfaces | Frost damage, impact, age |
| Mismatched bricks | Patchy appearance | Previous repairs with wrong bricks |
| Discolouration | Uneven or dull colour | Dirt, moss, efflorescence |
| Inappropriate repairs | Visible patches | Use of wrong materials |
Some of these issues are purely cosmetic, while others can lead to dampness and structural problems if left unattended.
Step 1 — Assessing the Brickwork
The first step in fixing ugly brickwork is a careful assessment. Look at:
- The condition of mortar joints
- Whether bricks are loose, cracked or flaking
- Any areas of staining or biological growth
- Previous repair work that looks out of place
Understanding the condition will determine whether you need cleaning, repointing, brick replacement, or cosmetic enhancement.
Step 2 — Cleaning the Brickwork
Often, what looks like ugly brickwork is simply dirty, stained or covered in algae and moss. Cleaning can make a dramatic difference.
Cleaning Techniques
| Method | Best For | Notes |
|---|---|---|
| Soft brushing + water | Light dirt | Gentle on mortar |
| Low-pressure wash | Moderate grime | Avoid high pressure to prevent damage |
| Steam cleaning | Biological growth | Effective without harsh chemicals |
| Brick-safe cleaners | Stubborn stains | Use products designed for brick |
After cleaning, allow the brickwork to dry fully before moving on to repairs.
Step 3 — Repointing Mortar Joints
One of the most transformative fixes for ugly brickwork is repointing — replacing deteriorated mortar between bricks. Mortar that has crumbled or eroded not only looks bad but also lets water in, leading to damp and damage.
Repointing involves:
- Removing old, loose mortar
- Mixing a suitable mortar (matching colour and composition)
- Packing new mortar into joints
- Tooling the joints for a neat finish
A well-repointed wall not only looks cleaner and more uniform, but it also improves weather resistance. Typical repointing costs are around £20–£30 per m² for materials, with labour increasing the total if a professional is engaged.
Step 4 — Replacing Damaged Bricks
If bricks are cracked, spalled, or badly damaged, they may need to be replaced. This process includes:
- Carefully removing the damaged brick
- Cleaning out the cavity
- Installing a new matching brick with fresh mortar
Matching the brick colour and texture is critical to avoid an obvious patch. If exact matches are hard to find, consider tinting or colour-enhancing techniques later (discussed below).
Step 5 — Matching Bricks and Blending Repairs
Ugly brickwork often stems from mismatched repairs where new bricks don’t blend with old ones. To improve this:
- Use reclaimed bricks of similar colour and size
- Repoint the entire wall rather than just patch areas
- Consider subtle colour treatments to unify tones
When bricks and mortar don’t match, the eye is drawn to the inconsistency — a key reason why some houses look patchy or unbalanced.
Step 6 — Cosmetic Enhancements
Even after structural fixes, brickwork can look dull or uneven. Cosmetic treatments can enhance the appearance without hiding the natural brick.
Options for Aesthetic Improvement
| Treatment | Purpose | Visual Impact | Longevity |
|---|---|---|---|
| Brick colour enhancers | Deepen tones | Natural finish | Medium |
| Brick tinting | Adjust colour | Uniform look | Long |
| Brick stains | Pigmented finish | Even colour | Medium |
| Sealers | Protect surface | Slight sheen | Depends on product |
Using these products carefully can help bring consistency to colour and texture across the wall. The right choice depends on how much you want to change the look and how permanent you want the effect to be. For detailed guidance on restoring brick colour and appearance, see BrickMakeover.

Step 7 — Consider Pointing Styles
The finish of mortar joints influences the look of brickwork. Different pointing styles can enhance or detract from overall appearance:
| Style | Effect |
|---|---|
| Flush pointing | Smooth and modern |
| Recessed (raked) | Highlights bricks |
| Weather-struck | Traditional, heritage look |
| Concave | Smooth, classic finish |
Choosing a pointing style that suits your property’s character can elevate the visual impact of brickwork.
Step 8 — Addressing Coatings and Renders
Some ugly brickwork results from inappropriate coatings like cement render or pebbledash. Removing these can reveal original brickwork, but it requires care to avoid damage. Once exposed, the brick may need cleaning and repair to look its best.
Practical Workflow for Fixing Ugly Brickwork
Here’s a step-by-step plan you can follow:
- Inspect and document the condition of brickwork
- Clean thoroughly to reveal true surface condition
- Repoint deteriorated joints
- Replace badly damaged bricks
- Match bricks and mortar colour
- Apply cosmetic enhancements as needed
- Select pointing style that suits the property
- Protect with a breathable sealer if appropriate
This systematic approach ensures both structural integrity and improved aesthetics.
Cost Breakdown Example
Below is an approximate cost estimate for fixing ugly brickwork on a typical detached house façade (approx. 60 m²):
| Task | Estimated Cost (£) |
|---|---|
| Cleaning materials | £40 – £120 |
| Repointing materials | £120 – £360 |
| Brick replacement materials | £50 – £200 |
| Colour enhancement/tinting | £150 – £350 |
| Sealers | £100 – £250 |
| Tools & consumables | £50 – £150 |
| Total (DIY) | £510 – £1,430 |
Note: Hiring a professional bricklayer will add labour costs. A full professional repoint and repair job can range from £2,000 to £6,000+ depending on size and complexity.
Common Mistakes to Avoid
Fixing brickwork isn’t just about slapping on new mortar or paint. Avoid these pitfalls:
- Using non-breathable coatings on old brick
- Rushing cleaning without proper drying time
- Mismatching brick types and colours
- Skipping structural repairs before cosmetic work
- Applying sealers that trap moisture
Taking the time to prepare and select suitable materials prevents future problems.
Maintenance After Repair
Once your brickwork looks good, keep it that way with regular maintenance:
- Inspect joints annually
- Clean gently as needed
- Remove moss and algae promptly
- Touch up repointing where mortar weakens
Good maintenance extends the life of repairs and keeps the façade attractive.
Fixing ugly brickwork is a blend of practical repair and aesthetic enhancement. With the right approach, even severely weathered or poorly repaired walls can be transformed into attractive, durable exteriors that complement your home’s style.
