top 6 masonry problems and their solutions

​Richmond Hill masonry, while durable and long-lasting, can still encounter certain problems over time. Here are some common masonry problems and their potential solutions:
​

1. 1. Efflorescence: Problem- Efflorescence occurs when white, powdery deposits appear on the surface of masonry. It is caused by the migration of salts to the surface through moisture. Solution: Remove the efflorescence using a stiff brush or water and a mild cleaning solution. Identify and address the source of moisture to prevent further salt migration. Consider applying a waterproof sealant to protect the masonry.
2. Cracks in Masonry: Problem- Cracks can develop in masonry due to various factors such as settlement, temperature changes, or structural stress. Solution-Evaluate the severity of the crack. Small hairline cracks can often be repaired with patching materials or sealants. Larger or more significant cracks may require professional assessment and repair by a qualified mason to ensure structural integrity.
3. Spalling: Problem- Spalling refers to the flaking or chipping of the brick surface, often caused by water infiltration, freeze-thaw cycles, or the use of incompatible materials. Solution- Remove the damaged or loose material and repair the affected area with appropriate patching materials designed for masonry repair. Address any water infiltration issues by improving drainage or applying waterproofing measures.
4. Leaning or Bowing Walls: Problem- Over time, brick walls can develop a lean or bow due to shifting soil, inadequate foundation support, or structural issues. Solution- Consult a qualified mason to assess the extent of the problem. Solutions may involve reinforcing the wall with steel supports, installing helical anchors, or in extreme cases, rebuilding the wall with proper structural support.
5. Mortar Joint Deterioration: Problem- Mortar joints can deteriorate and weaken over time due to weather exposure, age, or improper original construction. Solution- Repointing, also known as tuckpointing, is the process of removing damaged mortar and replacing it with fresh mortar. This helps restore the strength and integrity of the masonry wall. Hire an experienced masonry contractor to perform proper repointing techniques to ensure long-lasting results.
6. Stains or Discolouration: Problem: Masonry surfaces can develop stains or discolouration from factors such as water, algae, moss, or air pollution. Solution: Clean the affected area using appropriate cleaning agents or power washing techniques, depending on the type of stain. For persistent stains, consult a professional masonry cleaning service. Consider applying a protective sealant or coating to prevent future staining.

​We recently helped a homeowner in the Bayview Hill neighbourhood of Richmond Hill tackle a persistent issue with efflorescence and spalling bricks on their home's exterior. Due to Richmond Hill’s fluctuating weather conditions — from cold, damp winters to hot, humid summers — brick surfaces are especially prone to moisture buildup. Our team carefully removed the damaged bricks, treated the area to eliminate salt deposits, and installed new bricks with improved sealing techniques to prevent future issues. As a result, the homeowner’s property regained its curb appeal and is now better protected from moisture damage.
