Mortar Deterioration and the Importance of Brick/Block Maintenance

​Gaps or missing mortar between bricks or blocks can indicate underlying mortar deterioration, which can compromise the integrity and aesthetics of your home. In this blog post, we'll explore why mortar deterioration occurs, the signs to look out for, and the importance of addressing this issue promptly. Let's dive in and learn how to preserve the strength and beauty of your brick and block exteriors.

Mortar, the material used to hold bricks or blocks together, is susceptible to deterioration over time due to various factors:

• Weather Exposure: Exposure to moisture, temperature fluctuations, and freeze-thaw cycles can cause mortar to weaken and erode.
• Age and Settling: Over the years, the natural settling of a structure can place stress on the mortar joints, leading to cracks and gaps.
• Environmental Conditions: Factors like pollution, chemical exposure, and vegetation growth can accelerate mortar deterioration.

Gaps or missing mortar between bricks or blocks serve as visible indicators of mortar deterioration. Other signs to watch for include:

• Cracked or Crumbling Mortar: Look for cracks, crumbling, or disintegration of the mortar, indicating its weakened state.
• Loose Bricks or Blocks: Mortar deterioration can cause bricks or blocks to become loose or shift position.
• Water Infiltration: Moisture seeping through gaps in the mortar can lead to water damage, mold growth, and structural issues.
• Increased Drafts or Energy Loss: Deteriorated mortar can create gaps that allow air leakage, resulting in increased drafts and energy inefficiency.

Promptly addressing mortar deterioration is crucial for several reasons:

• Structural Integrity: Mortar provides stability and strength to brick and block structures. Addressing deteriorated mortar helps maintain the structural integrity of your home.
• Water Damage Prevention: Gaps in the mortar can allow water to infiltrate, potentially causing moisture damage, rot, and compromising the foundation.
• Energy Efficiency: Properly sealed mortar joints contribute to better insulation, reducing energy loss and improving the overall energy efficiency of your home.
• Aesthetics and Value: Maintaining well-maintained mortar enhances the curb appeal and value of your property, ensuring a visually appealing and well-preserved exterior.

​To address gaps or missing mortar, consider the following actions:

• Tuckpointing: Tuckpointing involves removing deteriorated mortar and replacing it with fresh mortar, restoring the strength and appearance of the joints.
• Hiring Professionals: For significant deterioration or complex projects, consult with professional masons who have the expertise to assess and repair mortar issues.
• Regular Maintenance: Implement a regular maintenance routine, including inspections, cleaning, and spot repairs, to identify and address mortar deterioration in its early stages.

Gaps or missing mortar between bricks or blocks are clear signs of mortar deterioration, which can compromise the structural integrity and aesthetics of your brick and block structures. By recognizing the signs of mortar deterioration, understanding its causes, and promptly addressing the issue through tuckpointing or professional assistance, you can preserve the strength, beauty, and value of your home. Remember, regular maintenance and proactive measures are key to ensuring the longevity and durability of your brick and block exteriors.
