Recognizing When You Need Repointing
Common Red Flags for Repointing
These signals will indicate whether your masonry work needs repointing:
- Structural Instability: If the building shows signs of instability, such as shifting or leaning, it may be due to deteriorating mortar.
- Discoloration in Masonry: Changes in color or patches could also indicate the deterioration of mortar.
- Mold Growth: The presence of mold or moss on walls might be a result of deteriorating brickwork and may suggest the need for repointing.
- Efflorescence: White deposit often seen on brickwork caused by soluble salts in the water that permeates through the walls can also be an indicator of mortar damage.
Expert Evaluation for Repointing
While there are noticeable signs that you need repointing, it’s often best to solicit professionals for a comprehensive analysis of the masonry. Licensed masons can check for less-obvious signs of damage that may not be visible to the untrained eye. They’ll also provide an accurate assessment of the extent of the work required, helping you to budget and plan accordingly.
List of Qualified Repointing Specialists
Getting your masonry evaluated by a professional is the first step towards its maintenance. But it’s essential to choose a reputable professional. Here’s a list of reliable online platforms where one can find trusted masonry professionals:
Additional Factors to Consider
Time and Frequency of Repointing
Repointing isn’t a process that needs to be done frequently. Typically, repointing should last about 50-100 years, depending on the mortar type, climate, and the building’s exposure to natural elements.
Cost Factors
The cost of repointing can vary greatly depending on factors such as:
- The complexity and size of the job
- The type of masonry
- The type of mortar used
Before committing to this project, ensure you have a solid understanding of the factors influencing cost. Some masons charge by the square foot, while others may charge hourly rates. Additionally, geographical location can also impact the cost.
Right Time for Repointing
Investing in repointing at the right time can prevent more extensive and costlier repairs down the line. If mortar joints show significant deterioration—whether cracks, holes, crumbling, or vegetation growth—it’s likely time for repointing. Delaying this process might lead to comprehensive damage that could involve rebuilding an entire wall, for example.

What Happens if You Don’t Repoint?
Increased Structural Damage
Neglecting to repoint deteriorating mortar can lead to severe structural damage over time. As mortar weakens, the load-bearing capacity of the masonry is compromised, potentially causing walls to buckle or even collapse. Unaddressed, small issues can quickly escalate to major repairs or even complete renovations, which are far more costly and time-consuming.
Water Infiltration and Interior Damage
Without proper repointing, water can easily seep into the masonry through cracks and deteriorated joints. This leads to:
– Interior Dampness: Moisture can travel through walls, causing damp patches and damaging interior finishes.
– Mold and Mildew Growth: Persistent damp conditions are ideal for mold and mildew, which pose health risks and create an unpleasant odor.
– Freeze-Thaw Damage: In colder climates, water trapped in the masonry can freeze and expand, exacerbating cracks and causing further deterioration.
Energy Inefficiency
Damaged mortar joints can significantly reduce a building’s thermal efficiency. Gaps and cracks in the masonry allow cold air to penetrate in the winter and cool air to escape in the summer, leading to:
– Higher Energy Bills: Your HVAC system must work harder to maintain a comfortable indoor temperature, resulting in increased energy costs.
– Reduced Comfort: Uneven temperatures can make indoor environments less comfortable, with cold drafts or warm spots.
Pest Infestation
Holes and gaps in the mortar can become entry points for pests such as insects and rodents. These unwelcome guests can cause additional damage and pose health risks to occupants. Pests entering through compromised masonry can be difficult to eliminate and often require professional pest control services.
Decreased Property Value
The aesthetic and structural issues caused by failing to repoint can significantly impact your property’s value. Potential buyers or renters are less likely to invest in a building that shows visible signs of neglect and structural deterioration. A well-maintained masonry exterior, on the other hand, boosts curb appeal and signals to buyers that the property has been well cared for.
Historical Property Risks
For historic properties, failing to repoint can result in the irreversible loss of historical and architectural elements.
Preservation guidelines often emphasize the importance of proper maintenance to retain the character and structural integrity of heritage buildings. Neglecting repointing in these contexts can lead to the forfeiture of historical authenticity and potential legal consequences.
