What's the Difference Between Tuckpointing and Repointing?

If you're like most homeowners, you probably don't know the distinct differences between tuckpointing and repointing. And that's okay! Most people don't. But if you're thinking of having your house's masonry worked on, it's important to know what the differences are, so you can make an informed decision about which option is best for your home.

In this blog post, we'll break down the differences between tuckpointing and repointing so you can better understand which one might be right for you. But first, let’s get to know what mortar is.

Mortar binds all the materials of your masonry structures together. It is a mixture of sand, cement, and water and bonds bricks, stones, or other building materials together. It is applied between the joints of the masonry units to create a strong and durable structure.

Mortar is very sturdy and can last for a hundred years. However, it can deteriorate after some time (usually after 20-30 years). Factors like weather exposure (freeze-thaw cycles), settlement issues, age and wear, poor quality materials, and water transfer can lead to mortar degradation.

Recognising the signs of your mortar deteriorating is crucial. When your brick wall needs repair, there are two common solutions: tuckpointing and repointing. But which is which? When do you use each of these repairs?

Main Differences Between Tuckpointing and Repointing

Tuckpointing was first applied in the 18th century as a cost-effective way of replicating joint brickwork. However, unlike Repointing, Tuckpointing uses two contrasting colours of mortar to create the illusion of fine joints. It includes filling in the raked or cut mortar joints with a mortar that matches the colour of the masonry units, and then applying a thin line of contrasting mortar on top to simulate a thin joint.

Below is a more detailed comparison of the Repointing and Tuckpointing:

Tuckpointing tends to be more expensive because of its use of additional materials and the meticulous application process. Repointing, on the other hand, is a more budget-friendly and practical option for addressing mortar issues.

Damaged or broken bricks, gap between bricks, and interior wall cracks are just some of the signs that your home or building needs repointing. However, the decision to repoint completely depends on the extent of joint deterioration. If 10 to 50% of the mortar joints show signs of damage, it is advisable to repoint 50% of them. However, when more than half of your mortar joints are damaged, a complete repointing is a more comprehensive solution.

You might need to consider tuckpointing when you start noticing your brick or stone walls showing signs of wear and tear. Keep an eye out for cracks, gaps, or crumbling mortar between the bricks – these are clear signals that the mortar joints are deteriorating and may need attention. If your once-sturdy walls start looking a bit weathered or you notice any discoloration, that could be another sign that tuckpointing is in order.
