How Often Should You Get Your House Repointed? A Guide to Maintaining Your Home’s Mortar Joints

Repointing brickwork is essential for maintaining the longevity and structural integrity of a house. Over time, the mortar between the bricks can deteriorate due to weather conditions, age, or poor installation. If left unattended, this can lead to water leaks, cracks, and even structural damage. Therefore, it is crucial to know when to repoint your house to avoid costly repairs.

The frequency of repointing depends on various factors such as the climate, the quality of the mortar, and the age of the house. The typical lifespan of mortar is around 40+ years. However, this is not a hard and fast rule, and some houses may require repointing sooner or later than others, especially when it comes to small repairs. It is recommended to inspect your brickwork regularly for signs of damage or wear and tear, such as cracks, crumbling, or water leaks, and to consult with a professional if you are unsure whether repointing is necessary.

What is Repointing?

Repointing is the process of repairing the mortar joints between bricks or stonework. Mortar is the material that is used to hold the bricks or stones together. Over time, the mortar can become damaged due to weathering, water infiltration, and other factors. Repointing involves removing the old mortar and replacing it with new mortar to restore the structural integrity of the wall. We wrote an in-depth article that covers this in more detail if you want to find out more.

The process of repointing involves grinding out the old mortar to a certain depth and then filling the joints with new mortar. The depth of the joint to be repointed depends on the size of the joint and the type of brick or stone used. The new mortar should match the colour and texture of the existing mortar to maintain the aesthetic appearance of the wall.

Repointing is a delicate process that requires precision and expertise. If the process is not done correctly, it can cause more damage to the wall than before. It is recommended to use a professional like us to perform the repointing work.

Repointing is necessary to prevent further damage to the wall and to maintain its structural integrity.

Cracks and gaps in the mortar can allow water to penetrate the wall, causing damage to the bricks or stones which can lead to other things such as dampness inside your home.

When Should You Repoint Your House?

Repointing your house is an important task that should not be overlooked. It is recommended that homeowners repoint their brick walls every 40+ years. However, the frequency of repointing may vary depending on several factors such as the age of the house, the type of mortar used, and the weather conditions in the area. You also need to factor in minor repairs which can occur more frequently.

One of the most important things to consider when deciding whether to repoint your house is the condition of the mortar. If the mortar is crumbling or cracking, it is a sign that it needs to be replaced. Another sign that your house needs repointing is if you notice gaps between the bricks. These gaps can allow water to seep into the walls, which can cause serious damage over time.

Bear in mind that repointing should be done by a professional company that specialises in this line of work. They should be able to remove the old mortar and replace it with fresh mortar that is compatible with the existing brickwork. The new mortar should be a mixture of lime, sand, and Portland cement, with a ratio that is appropriate for the placement and age of the bricks.

In addition to brick walls, chimneys also require repointing from time to time. Chimneys are exposed to the elements and can deteriorate quickly if they are not maintained properly. It is recommended that homeowners have their chimneys inspected and repointed at least every thirty years.

DIY vs Professional Repointing

Repointing can be a challenging and time-consuming task, requiring specialised tools such as a hammer, chisel, trowel, and mortarboard. DIY repointing may be an option for small areas or simple repairs, but for larger or more complex jobs, it is recommended to opt for a professional. Professional repointing not only ensures quality workmanship but also saves time and reduces the risk of costly mistakes.

When considering repointing costs, try to factor in the cost of labour, materials, and equipment. The cost of repointing varies depending on the size of the job, the accessibility of the work area, and the type of mortar used.

In addition to the cost factors, you need to think about the aesthetic and structural value of repointing work. Repointing not only improves the appearance of the building but also enhances its durability and resistance to water damage. It is especially important to consider these factors when working on listed buildings or structures located in hard-to-reach areas.
