What Is Brick Pointing and Why Does Your Property Need It?

Brickwork is one of the most durable elements of a building, but over time, weathering can wear away the mortar between the bricks. This process leads to deterioration that not only affects the look of a property but also weakens its structure. This is where pointing comes into play.



Understanding Pointing

Pointing is the process of renewing the external part of mortar joints in masonry. It involves removing damaged mortar and replacing it with new material to strengthen the wall and prevent water ingress. A properly done pointing job ensures the brickwork remains stable and visually appealing.

Why Mortar Joints Matter

Mortar joints act as a buffer for your brickwork. They absorb most of the wear and tear caused by changing weather conditions. When these joints start to crumble or crack, they expose the bricks to moisture, which can lead to structural damage. Replacing the mortar through pointing helps maintain the health of your walls.

How Weather Affects Brickwork

Rain, frost, and heat cause the mortar to expand and contract. Over time, this repeated motion creates gaps and weakens the joints. These small gaps allow moisture to seep in, which then causes the bricks to flake or shift. Timely pointing reduces these risks significantly.

Signs Your Property Needs Pointing

You don’t need to wait for serious issues to consider pointing. Crumbling mortar, loose bricks, or damp patches on internal walls are early signs. You might also notice the growth of moss or visible gaps between the bricks. All these signs indicate that it might be time for professional repointing.

Benefits of Brick Pointing

One of the most noticeable benefits is improved structural integrity. Fresh pointing strengthens the wall and extends the lifespan of your property. It also enhances insulation by preventing draughts and moisture. Visually, a repainted wall looks fresh and well-kept, which can boost curb appeal and property value.

Different Types of Mortar for Pointing

Choosing the right mortar is important. Lime mortar is often used for older buildings because it allows the structure to breathe. Cement mortar is more common in modern homes due to its durability. The type of mortar used should match the existing structure for both appearance and compatibility.

The Pointing Process Explained

The process begins with removing old mortar using hand tools or grinders. Care is taken not to damage the bricks. Once the joints are clean, new mortar is applied. The fresh mortar is then shaped and smoothed to match the existing style. Finally, it is left to cure for several days depending on weather conditions.

DIY or Hire a Professional?

Some homeowners consider doing a do-it-yourself job, but it's best left to experts. A poor pointing job can cause more harm than good. Professionals understand the correct depth and consistency of mortar and ensure a clean finish. They also complete the work quickly and safely, especially at height.

How Often Should You Repoint Brickwork?

There is no fixed timeline, but a typical wall may need repointing every 20 to 30 years. Factors like climate, location, and the type of mortar affect this schedule. Regular inspections can help detect early signs and prevent bigger problems.

Pointing Adds Long-Term Value

Investing in pointing is not just about repairs. It adds long-term value to your property by reducing future maintenance costs. A well-maintained exterior protects your interior from damp and mould, keeping your living space healthy and dry.

Preventative Maintenance Tips

Keep an eye on exposed walls, especially in older properties. After storms or heavy rainfall, check for crumbling joints or damp areas. Avoid using high-pressure washers on brickwork, as they can loosen the mortar. Simple actions like regular inspections can delay the need for full repointing.

Conclusion

Pointing is more than just a cosmetic fix. It preserves your property’s strength, appearance, and weather resistance. Ignoring damaged mortar can lead to serious structural issues and expensive repairs. Whether you own a period home or a modern building, keeping the brickwork in top condition is essential.
