Repointing is the most valued masonry restoration work in commercial and residential properties in NYC. Because NYC faces too much temperature variation, brickwork has to be repointed to let the masonry structures stay sturdy and durable for many years. It is advised by many professional contractors to identify the signs of damage in your masonry to keep it safe from further expensive repairs, which can lead to foundational damage. With that, the question arises, can weathering patterns on bricks indicate that repointing is required? The answer is YES! Because weathering patterns in brick are not about the blemishes, but they can affect the structural integrity.
In this blog, we’ll dive into the elements that damage the brickwork and indicate the need for repointing, while we also explore the preventive measures to take after repointing:
What are the elements that make the weathering patterns on brickwork?
Here’s the list of elements that can weather the brickwork. Most of these signs are due to natural & environmental wear and tear:
Salt Bloom
Due to harsh weather conditions like those in the Bronx and the humidity in Queens, it is noticed that their structures appear to have efflorescence, which is a white material made with water-soluble salts present in the masonry.
Evidence of structural concerns
- Moisture and humidity are trapped in the masonry. Excessive moisture is present in the masonry.
- Voids in the masonry let water into the mortar and brick structures.
Splitting in mortar
Splits in mortar are the widely known reason for weathering patterns, as they promote rapid material breakdown.
Evidence of structural concerns
- It leads to structural weakness and loss of structural resilience.
- It can cause displacement in the bricks and reduce the lifespan of masonry.
Brick delamination
Brick lamination is caused by the freeze-thaw damage when the mortar expands and contracts, which results in spalling and chipping off bricks and mortar.
Evidence of structural concerns
- The gaps in the mortar are becoming a passageway for water to enter the bricks, which results in major deterioration.
- Timely repointing helps in quick fixes and prevents brickwork from crumbling.
Visible brickwork blemishes
Due to weather exposure and moisture penetration, it is seen to have discoloration patches and blackish-greenish spots on the surfaces of brickwork, which mostly appear as mold and mildew.
Evidence of structural concerns
- Moisture ingress and seeping of water in the masonry.
- Improper repointing can lead to the trapping of moisture when the water-repellent sealants are not applied.
Buckling facades
Mortar joints deplete structural capacity and compromise the strength of the masonry with time, which leads to brick leaning and inconsistent masonry layout of the façade.
Evidence of structural concerns
- Bricks and mortar lose adhesion and grip due to recurring brick drop issues.
- It loses the vertical weight distribution capacity of the buildings.
Protective Measures After Repointing
It is important to make sure to keep proper maintenance of the masonry after repointing is done to prevent destruction of your mortar and brickwork. Use the following tips to avoid weathering after repointing:
- Always seal your walls with vapor-permeable waterproof coatings after repointing to stop water ingress without disrupting airflow.
- Use soft and gentle washing solutions and techniques to clean the bricks with adequate water pressure.
- Make sure that the water channeling system is good enough with proper gutters.
- Regular upkeep should be done to identify any damage or moisture intrusion.
Proper repointing also supports insulation performance and energy savings — learn how brick pointing improves wall insulation.
Final Thoughts
To sum up, yes, weathering patterns on bricks can help determine the need for repointing, as it not only causes damage to the surface but can also badly destroy the underlying masonry. It’s better to address the signs you identify without neglecting them to prevent future costly damages and help retain the timeless charm and value of your brick structures.
