Pointing & Repointing brickwork : Why does your house need repointing ?

Updated: Jul 24, 2023

Houses may need repointing for several reasons, and it primarily involves the deterioration of the mortar joints between the bricks or stones in the masonry. Some common reasons why a house may need repointing include:

  1. Age and Weathering: Over time, exposure to weather elements, such as rain, snow, UV rays, and temperature fluctuations, can cause the mortar to degrade and erode. This can lead to cracks, gaps, or crumbling mortar joints.

  2. Water Penetration: Deteriorated mortar joints can allow water to seep into the masonry. Moisture penetration can lead to further deterioration, mold growth, and damage to the interior walls and structural components of the house.

  3. Structural Integrity: Failing mortar joints can compromise the structural stability of the masonry. If the mortar is weak or missing in certain areas, it can result in loose bricks or stones, causing potential hazards and safety concerns.

  4. Aesthetic Reasons: Repointing can also be done for cosmetic purposes. Deteriorated or discoloured mortar joints can give a weathered and aged appearance to the house. Repointing can improve the overall appearance and curb appeal of the property.

  5. Preventive Maintenance: Regular maintenance and repointing can help extend the life of the masonry and prevent more extensive repairs in the future. Catching and addressing minor issues early on can save time and money in the long run.

  6. Historical Restoration: In the case of historical buildings or heritage properties, repointing becomes essential to preserve the original character and integrity of the structure.

  7. Home Renovation: When renovating a house, repointing may be necessary to prepare the masonry for other improvements or to ensure the building's structural soundness.

It's essential to keep an eye on the condition of the mortar joints and the overall masonry of your house. If you notice signs of deterioration, such as cracks, crumbling mortar, or loose bricks, it's a clear indication that repointing may be needed. Hiring a professional mason or roofing contractor to inspect and assess the condition of the mortar joints is recommended to determine if repointing is necessary and to ensure that the work is done correctly.
