What Is Repointing and When Do Birmingham Homes Need It?

Repointing is a key part of maintaining brickwork, particularly in older properties where the mortar has been exposed to decades of weather. Many homes in Birmingham, including those in Kings Norton, Handsworth, Erdington and Harborne, rely on original brickwork that naturally weakens over time. Mortar is the material that binds bricks together, and when it begins to erode, the entire structure becomes more vulnerable. Cracked or crumbling mortar allows water to seep into the brickwork. During colder months, this moisture freezes and expands, widening gaps and causing further damage. Over time, this leads to damp patches inside the home, weakened walls and a noticeable drop in energy efficiency. Chimneys are particularly prone to mortar decay due to constant exposure. Repointing replaces the damaged mortar with new, compatible material. Matching the mortar type is important for both structural and aesthetic reasons. Traditional Birmingham properties often use softer mortars that allow the building to breathe, while newer homes may require a more modern blend. Using the wrong type can trap moisture and create future issues. A professional repointing service carefully removes the failing mortar without damaging the brick edges. The new mortar is applied to match the property’s appearance and restore its strength. Once complete, the brickwork becomes more resistant to weather and better protected against water penetration. Homeowners often notice improved warmth, reduced damp issues and a refreshed exterior look after repointing. For properties exposed to high wind or rain, or those showing visible mortar deterioration, repointing is an investment that provides long term protection.
