What is the lifespan of a repointing job? (Guide 2024)

The Lifespan of Masonry Repointing

Repointing, a crucial aspect of maintaining brick and stone walls, is a topic of concern for many homeowners in Montreal, Laval, Longueuil, the South Shore, and the North Shore. But how long can one realistically expect repointing to last before needing to redo it? This question is pivotal for those looking to preserve the integrity and beauty of their masonry. In this article, we will delve into the details and unveil the key factors that influence the lifespan of masonry repointing.

Determining Factors

1. Quality of Materials

The first factor to consider is the quality of materials used during repointing. Opting for high-quality materials will ensure a longer lifespan. The experts at Maçonnerie Montréal always recommend the use of premium mortar, which better withstands weathering and wear. The choice of the appropriate brick or stone is also crucial, as some types are more durable than others.

2. Skill of the Craftsman

The skill of the craftsman plays a major role in the durability of repointing. A skilled professional is well-versed in the proper repointing techniques, ensuring correct and uniform mortar application. Mistakes made by an inexperienced artisan can lead to premature issues such as cracks or mortar detachment.

3. Weather Conditions

In Montreal and its surroundings, weather conditions can be extreme, with cold winters and hot summers. These temperature variations can exert significant pressure on masonry. High-quality repointing is essential to withstand these temperature fluctuations. Freeze-thaw cycles can cause substantial damage if there are weaknesses in the repointing.

4. Regular Maintenance

Regular maintenance is crucial to extend the lifespan of repointing. Homeowners must monitor the condition of their masonry and respond promptly to signs of damage or deterioration. Periodic cleaning and sealing of the repointing also contribute to its longevity.

Average Lifespan

On average, quality repointing can last between 20 and 30 years. However, it's important to note that this duration can vary depending on the previously mentioned factors. Superior-quality repointing, carried out by experienced professionals with top-notch materials, can even last longer.

Signs of Repointing Aging

It's essential to recognize signs of repointing aging to take action promptly when repair is needed. Here are some indicators to watch for:

1. Cracks

Cracks in the repointing are an obvious sign of deterioration. They allow moisture to penetrate, which can lead to more severe issues if not repaired promptly.

2. Mortar Detachment

If the mortar begins to detach from the bricks or stones, it's time to take action. Detachment can result from poor initial application or damage from weather conditions.

3. Erosion

Mortar erosion is another sign of aging. Areas where the mortar erodes should be repaired to prevent further deterioration.

4. Discoloration

If the repointing becomes discolored, it may be due to exposure to the elements or mold growth. Proper cleaning and sealing can address this issue.


In summary, the lifespan of masonry repointing depends on several factors, including the quality of materials, the skill of the craftsman, weather conditions, and regular maintenance. On average, well-maintained repointing can last between 20 and 30 years or more. To ensure the longevity of your masonry, it's crucial to rely on qualified professionals like Maçonnerie Montréal, who use top-quality materials and master the art of repointing. Don't wait for signs of deterioration to appear; take prompt action to preserve the beauty and integrity of your property.
