Repointing and Tuckpointing are related forms of brickwork repair. The primary difference is that repointing involves the removal and replacement of a worn out mortar layer around existing bricks and the resetting of bricks where needed.
In contrast, tuckpointing involves the removal and replacement of deteriorated mortar only, while leaving the bricks intact. Repointing is necessary when deteriorated mortar joints are too extensive or severe to be repaired using only tuckpointing.
In tuckpointing, a strong and durable mortar is used, usually with a matching or contrasting color, to “tuck up” the deteriorating or damaged mortar joints. The contrasting color of the mortar often gives the impression of being fine lines of another color in the brickwork, hence the name “tuckpointing.
” This form of brickwork repair is often used to restore aesthetic appeal or to upgrade the condition of a brick façade.
Repointing involves the removal of all of the damaged and deteriorated mortar from the brickwork, and the resetting of any out of position bricks. A strong bed mortar is applied to the brick wall, and mortar joint raking is carried out to create the appropriate joint profile.
Repairing brickwork with repointing is essential in ensuring the brickwork is structurally sound and weather resistant. Repointing also lessens the probability of water damage and mold growth in the brickwork.

Is repointing cheaper than tuckpointing?
The cost of repointing vs. tuckpointing depends on a variety of factors, including the size of the job, the type of masonry being worked with, and the labor rate. Generally, repointing is less labor intensive than tuckpointing and can be a cheaper option.
Repointing is typically used for brick and stone walls and involves replacing damaged mortar joints with new mortar; it is relatively straightforward and involves fewer steps than tuckpointing. Tuckpointing is used for brickwork and involves matching the color and texture of the existing mortar with a new type of mortar that is then applied in a decorative pattern.
As a result, tuckpointing is more labor intensive and may be a more expensive option than repointing.
How do you tell if you need repointing?
If you notice that the mortar between your bricks or stones is crumbling, cracked, or beginning to fall out of the joints, then you likely need repointing. You may also notice white powdery deposits on the outer wall, as well as moisture coming through your walls.
Additionally, if your chimney is leaning, or if you have water leaks around areas with mortar, then you could need repointing. It’s also important to inspect for gaps, as pointing should result in that area being filled.
Lastly, if your walls are bulging, then you may need repointing. It’s best to have an inspection from a qualified professional to properly determine if repointing is necessary.
Why do they call it tuck pointing?
Tuck pointing is an old masonry technique that is used to repair and restore the appearance of deteriorated or damaged brick, stone, and other masonry structures. It is called tuck pointing because it involves careful insertion of small “tucks” of mortar between bricks, stones, and other materials.
Tuck pointing is used to help keep moisture and pests out of the building, to ensure that the structure is sound, and to maintain its aesthetic beauty. The fine, closely-cemented lines of tuck pointing are often used to help the wall look attractive.
Tuck pointing also helps strengthen the masonry structure, making it more able to withstand the weight of a heavy load, such as a roof.
Tuck pointing is a careful, meticulous process that requires a skilled mason to match the color and texture of the existing brick and mortar, ensuring a proper fit and optimal blend with the rest of the wall.
It is essential to hire a professional tuck pointer to ensure the job is done properly and to maintain a wall’s structural integrity over time.
Can you repoint over old mortar?
Yes, it is possible to repoint over old mortar. However, there are some things to consider before starting the job.
To begin with, you must assess the condition of the existing mortar. It is important to make sure the existing mortar is in good condition and free from cracks, crumbling, and missing sections before applying the new layer of mortar.
If the existing mortar has any damage, it is essential to remove it first before repointing.
Next, you must work out the best mix of mortar for your project. Generally, the mix should consist of 1 part cement to 3 parts building sand. The quality of the sand and the cement used is important to ensure that the mortar sets well.
You should also ensure that the old and the new mortar match in terms of color and texture. Variations in color and texture can cause the pointing to look poorly finished.
Once you are happy with the mix you can start to repoint the old mortar. To do this correctly, you must create a joint that is slightly concave and follow the same line as the existing mortar. This helps to create a smooth finish to the job.
Finally, it is important to use the correct tools for repointing. Generally, it is best to use a pointing trowel, a hawk, and a straight-edge. These tools can help you to make sure the mortar lines are even, for a professional-looking finish.
How long does repointing last?
Repointing is a process of replacing decayed or deteriorating mortar between the bricks of a structure. Its purpose is to restore and strengthen the structure’s integrity. The duration of the repointing process varies according to the type of structure and the extent of the damage.
For a single-storey home, a typical repointing job could take up to a week, but for a large commercial building the process may take several months. Additionally, good quality repointing requires preparatory work such as cleaning and scraping out the old mortar and sandblasting.
Depending on the size of the structure and the amount of work that needs to be done, this alone could take up to several days. In both cases, the repointing work itself is just one stage of the job, which may need to be supplemented by other repairs and improvements too.
Is tuckpointing necessary?
Tuckpointing is a term used to refer to a type of mortar joint repair, sometimes referred to as repointing. Tuckpointing is necessary because it seals the mortar joints that over time become loose, cracked, and otherwise compromised.
This type of repair often takes place when the masonry has been damaged or degraded from water damage, extreme temperatures, or just wear and tear over time. When the mortar joints become compromised, the masonry will suffer from moisture intrusion, as well as be exposed to other dangers, such as microorganisms that can cause deterioration and rot.
In severe cases, tuckpointing can be necessary to save a wall or masonry structure from further damage.
In addition to protecting the masonry structure, tuckpointing can also be necessary to ensure the aesthetic appeal of the structure. Tuckpointing is done properly by professionals who are familiar with the appropriate methods and materials used to properly tuckpoint a structure.
In some cases, simply cleaning the existing mortar joints can be sufficient to improve the structure’s integrity and appearance. In other cases, more extensive tuckpointing may be necessary in order to repair the mortar joints and restore the masonry to its original condition.
In any case, if a masonry structure is suffering from mortar joint damage, a professional should be consulted to determine the best method for repair.
What does tuckpointing look like?
Tuckpointing is a special masonry technique used to repair or strengthen existing structures or walls. It involves “pointing” or replacing the mortar between bricks, blocks, or stones to make them fit more closely together and fill any gaps that may have formed due to changes in temperatures, water intrusion, or other natural causes.
The process involves removing the damaged or deteriorating mortar from between the masonry units, then filling or repointing the joints with new mortar that closely matches the color and texture of the existing brick or block.
To be effective, tuckpointing must reach the full depth of the joint and about one inch on either side to ensure a solid bond between the bricks, blocks, or stones.
Tuckpointing is usually done with white or gray mortar, which is formulated to match the mortar to its surroundings. This allows the structure to look original afterward, other than in areas where new tuckpointing has been done.
By using tuckpointing as part of regular maintenance, it’s possible to preserve the integrity and attractive aesthetics of the existing masonry on your home or building.
What kind of mortar do you use for tuckpointing?
Tuckpointing mortar is a special type of mortar that is used for restoring stonework or brickwork. It is typically made of a mixture of 1 part Portland cement, 2 parts hydrated lime, and 9 parts clean, sharp sand.
The proportion of each ingredient in the mixture is critical, as too much Portland cement will cause the mortar to be too hard and brittle. Too little Portland cement will produce a mortar that is too weak and soft.
Hydrated lime will help to reduce shrinkage and cracking, while sand gives the mix its workability and strength.
When applying tuckpointing mortar, the angle of the trowel should be adjusted to the work angle. The mortar should be mixed with less water and applied to the joints of the stonework or bricks in straight lines.
The mortar should be packed in at different heights to achieve a concave curve that is slightly deeper than the points of the stone. Finally, the mortar should be struck with a denticulated trowel to ensure an even finish.
How often should you tuck point?
Tuck pointing typically should be done every 5-10 years depending on the level of wear your masonry is experiencing. That being said, some masonry might need to be tuck pointed more frequently due to the amount of weathering it is exposed to.
It is important to inspect your masonry regularly to ensure the longevity of your wall or structure. If you notice small cracks or areas of loose mortar, then it is likely time for a tuck pointing job.
It is also important to note that tuck pointing should be done in cooler weather because mortar is not as likely to dry out quickly and can have time to set and cure properly. Doing tuck pointing in the heat or sun can lead to lower quality work and a short lifetime for the mortar repairs.
What happens if you don’t do tuckpointing?
If you don’t do tuckpointing, it can result in serious damage to your brick structure over time. Tuckpointing seals the mortar joints in between bricks to keep moisture and dirt out. Without proper tuckpointing, the mortar will wear away, leaving the brick structure vulnerable to moisture, which can infiltrate and seep into the brick.
This can cause the brick to age more quickly, which in turn leads to crumbling, crumbling mortar, cracking bricks, and spalling. Additionally, if the moisture seeps into the basement or other interior areas, it can lead to mold growth, which is both a health concern and can lead to structural issues.
Tuckpointing also prevents insect infestations, as insects can use the cracks in the mortar as entry points into the structure. All in all, not doing tuckpointing can result in significant damage to your brick structure that may be costly to repair or even irreparable.
How often should tuckpointing be done Chicago?
Tuckpointing in Chicago should be done based on an assessment of the existing mortar joints. Typically, tuckpointing should be done every 10-20 years in Chicago, depending on the age and physical condition of the mortar joints.
If the mortar is still in good condition, the tuckpointing may be done every 10-15 years. However, if cracks or gaps start to form in the mortar, it is likely time to start tuckpointing procedures. In addition to regular tuckpointing every 10-20 years, it is important to address any other signs of wear and tear on the masonry wall or chimney, such as damaged bricks, weathering, or discoloration.
If any of these signs of wear and tear are present, tuckpointing may need to be done more frequently. Ultimately, in Chicago it is important to assess the condition of the mortar and the masonry surface, and work with a professional mason to determine the appropriate frequency for tuckpointing in order to maintain the structure and integrity of the building.
Can tuck pointing be done in winter?
Yes, tuck pointing can be done in winter. However, the cold temperatures can make it more difficult and time-consuming to complete a tuck pointing job. Cold weather can make mortar and grout harder to work with, as they take longer to set.
Bricks and mortar are also more prone to cracks and damage due to the cold temperatures. Additionally, the cold air can cause mortar and grout to shrink more than in warmer temperatures, which can cause certain mortar joints to become loose.
That being said, the job can still be done in winter, but extra precautions should be taken to ensure your tuck pointing job is successful and will last for years.
How often should there be expansion joints in brick walls?
Expansion joints should be built into brick walls on each side of the structure, every 10 to 40 feet depending on the height and complexity of the wall. Expansion joints should also be located where the walls intersect with other walls, around corners, and at the end of the wall.
Expansion joints should also be located around openings in the wall, such as windows and doors. Additionally, expansion joints should be placed at ends of a horizontal wall at least the width of the wall, or where a wall intersects with a different plane.
When it comes to activities such as re-pointing and general maintenance, expansion joints should also be maintained to help prevent structural damage to a brick wall.
Can I tuck point myself?
Yes, you can tuck point yourself, however, it is not advised due to the complexity of the process. Tucking requires not only mastery, but also practice to do properly. If not done properly, tuck pointing can actually damage the wall rather than adding to its longevity and beauty.
For this reason, it is strongly recommended that you seek the assistance of a professional mason experienced in the art of tuck pointing. A qualified professional mason will have the necessary skill, experience, and proper tools to ensure the job is done properly and safely.
