Pointing & Repointing Brickwork: A Bricklayer’s Approach to Durable Walls

A well-built brick structure is only as strong as the mortar that holds it together. Over time, even the best brickwork needs attention, especially when joints begin to crack or wear away. This is where a skilled bricklayer plays a vital role. Pointing and repointing are two essential bricklaying processes that keep walls sturdy, weatherproof, and visually appealing. Whether you’re working on a new project or restoring older brick structures, understanding these techniques ensures long-term durability and professional results.

What Is Pointing and Why It Matters

Pointing is the process of finishing mortar joints when brickwork is first laid. While it may seem like a small detail, proper pointing protects the wall from moisture penetration, enhances its strength, and gives the finished surface a clean, uniform appearance. The final look of the building often depends on how neatly the joints are shaped, which is why pointing is a critical step in quality bricklaying.

Different pointing styles—such as flush, recessed, bucket-handle, and weather-struck—can completely change the look and performance of a wall. A well-trained bricklayer will choose the correct finish depending on the property’s age, the climate, and the aesthetic preferences of the client.

Why Repointing Is Essential for Brickwork Repair

As brickwork ages, the mortar naturally deteriorates due to weathering, moisture, frost action, or simple wear and tear. When joints become cracked, crumbly, or recessed, the stability of the entire wall is affected. Repointing is the process of removing damaged mortar and replacing it with new, properly matched mortar.

Repointing is a crucial brickwork repair technique because:

1. It strengthens the wall: Loose or weakened joints reduce the ability of the wall to stay stable. Repointing restores the connection between bricks and reinforces structural integrity.

2. It prevents water penetration: Worn joints allow rainwater to seep inside the wall. Over time, this leads to damp issues, mould, and even internal structural damage. Repointing seals these gaps and protects the building from moisture.

3. It improves insulation: When joints deteriorate, small gaps create drafts and heat loss. Repointing helps maintain consistent temperature inside the building, improving energy efficiency.

4. It enhances visual appeal: Freshly repointed brickwork instantly upgrades the appearance of any property. Clean, neat joints add definition and improve curb appeal—especially important for older homes or heritage properties.

5. It prevents expensive future repairs: Early brickwork repair stops problems from spreading. Neglected mortar can cause bricks to crack, loosen, or spall, resulting in higher repair costs later.

Signs That a Wall Needs Repointing

A bricklayer can assess the condition of a wall and identify key signs such as:

• Mortar crumbling when touched

• Deep gaps between bricks

• Mortar visibly fallen out of joints

• Bricks becoming loose or unstable

• Interior damp patches or peeling paint

• Joints looking significantly recessed

• Hairline cracks running along mortar lines

Identifying these signs early allows for timely brickwork repair, stopping further deterioration.

How a Bricklayer Should Approach Repointing

Repointing is a skilled process that requires precision and the right tools. A professional bricklayer typically follows these steps:

1. Raking out the old mortar: The first step is carefully removing the damaged mortar to the correct depth, usually 15–20 mm. This must be done without damaging the bricks. Using suitable raking tools ensures clean, safe removal.

2. Cleaning the joints: Once old mortar is removed, all dust and debris must be brushed out. Clean joints allow the new mortar to bond properly and prevent weak patches.

3. Preparing the new mortar: The new mortar should match the original in strength, colour, and texture. Using a mortar that is too strong or too hard can damage older bricks, while a weak mix won’t last. Matching the mix is especially important in heritage or traditional bricklaying.

4. Applying the mortar: The fresh mortar is packed firmly into the joints using suitable pointing tools. Each joint is filled completely to avoid air pockets and ensure long-lasting strength.

5. Finishing the joints: The joints are shaped according to the chosen finish—whether weather-struck, flush, recessed, or bucket-handle. The finish not only affects the appearance but also determines how well the wall sheds water.

6. Allowing the mortar to cure: Proper curing is essential for mortar strength. The brickwork may need to be lightly misted or protected from harsh weather during curing to achieve maximum durability.

Why Professional Bricklaying Expertise Is Important

Pointing and repointing might seem straightforward, but poor workmanship can cause more harm than good. Using the wrong mortar mix, raking too deeply, or applying mortar incorrectly can lead to future cracking, moisture retention, or brick damage. A skilled bricklayer understands the structure, materials, and techniques required to carry out effective brickwork repair.

Conclusion

Pointing and repointing are essential techniques that help preserve the strength, appearance, and longevity of any brick structure. With the right skills, materials, and attention to detail, a bricklayer can restore damaged joints, prevent moisture issues, and maintain the overall stability of a wall. Regular brickwork repair not only improves performance but also protects the property from costly future problems. By investing in proper maintenance and high-quality bricklaying work, homeowners can ensure their brickwork stands strong for decades to come.
