Masonry items, such as block, stone, or brick, can last up to 100 years with virtually no maintenance. However, the mortar joints can present damage if these are exposed to harsh weather conditions –even if the bricks are in excellent shape. If the mortar shows cracks or detriment due to water exposure, it needs to be repaired. The most common and efficient way to do it is by Tuckpointing. If you’re not familiar with the term, don’t worry. Here’s a crash course:

1.      What is Tuckpointing?

It is a technique used to repair mortar joints in stone or bricks and to enhance the appearance of masonry. The process consists of grinding the deteriorated mortar and filling in with new material. The new mortar must match the color of the bricks; then, a thin line of putty is applied in the center of the joint. This layer has a contrasting color against the bricks. The technique gives the impression of well-maintained, delicate, and narrow joints made. 

2.      When should you Tuckpoint?

Here’s a simple test you can do. Take a regular key and stroke the mortar joint. If the masonry is in good shape, the rubbing will not scratch it at all. But, if the scratching releases powdered material, then you need to repair it. You can either perform this basic test or call an expert for a more professional evaluation. Remember, tuckpointing is also used for cosmetic purposes. It is used widely on historic brick homes; the technique helps recapture the home’s original appearance. 

3.      What happens if I don’t Tuckpoint?

When the technique is appropriately applied, the mortar joints become relatively waterproof. It increases the life of your walls. On the contrary, weakened or deteriorated mortar allows moisture and humidity to infiltrate the brick or stone masonry. If the moisture gets behind the wall, the problem will be much severe. In the worst cases, the only fix will be to tear the wall down. By not tuckpointing on time, you will lose time and money. 

4.      Is there a point where it is too late to Tuckpoint?

Unfortunately, yes. Loose masonry units –stone or bricks –mean bad news. If your situation gets to this point, the only way to fix it is to pull down the masonry wall and build it again. In terms of money, there is no comparison between doing this final solution and Tuckpointing on time. 

5.      Can I prevent mortar deterioration?

The lifespan of mortar joints is around 30 years. The wear and tear obey to different causes. We mentioned moisture but also erosion from exposure to extreme temperatures, low-quality craft, or even pressure from the weight of the masonry. Mortar joints are the weakest part of a wall; inevitably, you will eventually have to maintain and repair. 

Although labor-extensive, Tuckpointing is an efficient, effective, cost-worthy technique to keep your masonry walls and chimneys in optimal condition.
