Why Do Bricks on the Front of a House Need Replacing?

Before jumping into the replacement process, it's important to understand why bricks deteriorate in the first place. Recognising the root cause helps you prevent future damage and choose the right repair approach.

Frost and freeze-thaw cycles are among the most common culprits. When water seeps into tiny pores in the brick and then freezes, it expands. Over repeated cycles, this causes the face of the brick to flake off - a process known as spalling. This is especially common in the UK, where damp winters and fluctuating temperatures are the norm.

Moisture penetration from faulty guttering, leaking downpipes, or poor drainage can saturate brickwork over time. Persistent dampness weakens the brick and the mortar joints surrounding it, eventually leading to crumbling and decay.

Impact damage from accidental knocks, falling objects, or even tree roots pressing against the wall can break or dislodge bricks. While this type of damage is usually localised, it still requires prompt attention to prevent water ingress.

Age and natural wear also play a role. Older homes, particularly those built with softer handmade bricks, are more vulnerable to surface erosion. Over decades, even well-maintained brickwork will show signs of ageing.

Subsidence or structural movement can cause breaks that run through both bricks and mortar joints. If you notice stepped or diagonal breaking, it's wise to consult a structural engineer before replacing any bricks, as the issue may be deeper than surface-level damage.

Tools and Materials You'll Need

Having the right tools on hand before you begin makes the job significantly smoother. Here's what you'll typically need to replace brick on the front of your house:

- Cold chisel (bolster chisel)
- Club hammer
- Pointing trowel
- Brick trowel
- Mortar mix (matching existing mortar colour and type)
- Replacement bricks (matching the original as closely as possible)
- Safety goggles and heavy-duty gloves
- Dust mask
- Wire brush
- Spray bottle with water
- Bucket for mixing mortar
- Spirit level

Finding matching bricks can be one of the trickiest parts of the job. If your home is older, standard bricks from a builder's merchant may not match perfectly. Brick matching services and architectural salvage yards can be excellent resources for sourcing reclaimed bricks that blend seamlessly with your existing facade.

Step-by-Step Guide to Replacing a Brick on the Front of Your House

Step 1: Assess the Damage

Start by inspecting the damaged area carefully. Determine how many bricks need replacing and check whether the surrounding mortar joints are also compromised. If the damage is widespread or appears structural, it's best to call a professional bricklayer or surveyor.
For isolated damage - one or a few bricks - a confident DIYer can handle the repair with patience and the right approach.

Step 2: Remove the Damaged Brick

This is the most labour-intensive part of the process. Begin by removing the mortar around the damaged brick using a cold chisel and club hammer. Work carefully around all four edges of the brick, chipping away the mortar bit by bit.

Always wear safety goggles and gloves during this step, as small fragments of brick and mortar will fly off. Angle the chisel slightly away from surrounding bricks to avoid damaging them.

Once the mortar is sufficiently removed, the damaged brick should loosen. You may be able to pull it out by hand or lever it out gently with the chisel. If the brick is severely crumbled, it may come out in pieces - that's perfectly fine.

Step 3: Clean the Cavity

After removing the old brick, use a wire brush to clean the cavity thoroughly. Remove all loose mortar, dust, and debris from the top, bottom, sides, and back of the opening. A clean cavity ensures the new mortar bonds properly and the replacement brick sits securely.
Lightly dampen the cavity with a spray bottle of water. This prevents the dry surrounding brickwork from absorbing moisture from the fresh mortar too quickly, which would weaken the bond.

Step 4: Prepare the Mortar

Mix your mortar according to the manufacturer's instructions. For most brick replacement jobs, a standard mix of one part cement to four or five parts building sand works well. Add a small amount of plasticiser to improve workability.

If your home has older lime mortar joints, consider using a lime-based mortar instead of a cement-based one. Lime mortar is softer and more flexible, which is better suited to older, softer bricks. Using hard cement mortar on a period property can actually cause more damage over time, as it doesn't allow the brickwork to breathe or move naturally.

Colour matching the mortar is just as important as matching the brick. You can add pigments or choose coloured sands to achieve a closer match. It's worth testing a small batch first and letting it dry, as mortar changes colour significantly as it cures.

Step 5: Butter and Insert the New Brick

Apply a generous layer of mortar to the bottom, top, and both sides of the cavity using your brick trowel. Then apply mortar to the top and both ends of the replacement brick itself - this is known as "buttering."
Carefully slide the brick into the cavity, pressing it firmly into place. Use a spirit level to check that it sits flush with the surrounding bricks both horizontally and vertically. Tap it gently with the handle of the trowel to adjust its position.

Step 6: Point the Joints

Once the brick is in position, use your pointing trowel to fill any remaining gaps in the mortar joints. Shape the mortar to match the profile of the existing joints - whether they are flush, recessed, or weathered.
Smooth the joints neatly and remove any excess mortar from the brick face with a damp sponge before it hardens. Clean pointing makes a significant difference to the finished appearance of the repair.

Step 7: Allow to Cure

Fresh mortar needs time to cure properly. Avoid disturbing the area for at least 24 to 48 hours. In cold or damp weather, curing may take longer. If rain is expected, consider covering the repair loosely with plastic sheeting to protect it while still allowing air circulation.

When Should You Call a Professional?

While replacing a single brick is well within the capability of most handy homeowners, there are situations where professional help is the smarter choice:

- Large areas of damage - replacing multiple bricks across a wide section requires experience to maintain structural integrity and visual consistency.

- Structural breaking - if breaks follow a stepped pattern through mortar joints or run diagonally across the wall, this may indicate subsidence or foundation issues.

- Listed or heritage buildings - period properties often have specific requirements regarding materials and techniques. Using the wrong mortar or brick can cause further damage and may breach planning regulations.

- High-level work - replacing bricks above ground-floor level involves working at height, which carries significant safety risks. Scaffolding and professional expertise are advisable.

- Damp or water ingress issues - if the brick damage is caused by an underlying moisture problem, simply replacing the brick won't solve the issue. The source of the moisture must be addressed first.

How Much Does It Cost to Replace Brick on the Front of a House?

Costs vary depending on the extent of the damage, the type of brick, and whether you hire a professional or tackle the job yourself.

For a DIY repair, the main expense is materials. Replacement bricks can range from a few pence for standard bricks to several pounds each for reclaimed or specialist bricks. Mortar, tools, and sundries might add another £20 to £50.

For professional brick replacement, expect to pay anywhere from £150 to £500 or more for a small repair, depending on access, complexity, and your location. Larger repointing or brick replacement projects can run into the thousands.

Investing in quality materials and skilled labour is worthwhile, as a poor repair can look worse than the original damage and may lead to further problems down the line.

Tips for Maintaining Your Brickwork After Replacement

Once you've completed the repair, a little preventative maintenance goes a long way:

- Inspect your brickwork annually, particularly after winter, for signs of new breaking or spalling.
- Keep gutters and downpipes clear to prevent water from overflowing onto the wall.
- Address repointing early - if mortar joints start to recede or crumble, repoint them before moisture can penetrate deeper into the brickwork.
- Avoid pressure washing brick walls, as the high pressure can force water into the brick and damage the surface.
- Ensure adequate ventilation around the base of walls and check that ground levels haven't risen above the damp-proof course.
