Chimneys are constantly exposed to rain, frost, wind and temperature changes, making them one of the most vulnerable parts of any building.
At SGT Repointing Solutions, we provide specialist chimney repointing services throughout Kent and Sussex, restoring weathered mortar joints and helping to protect chimney stacks from further deterioration.
Whether your chimney is constructed from traditional brick, stone or lime mortar masonry, we carefully assess the condition of the stack and use suitable materials and finishes to match the age and character of the property.
Repointing weathered chimney stacks, failed mortar joints, traditional brick chimneys and heritage masonry.
Over time, exposure to harsh weather causes mortar joints within chimney stacks to weaken, crack and erode.
Once the mortar begins to fail, water can penetrate into the structure of the chimney, leading to frost damage, loose brickwork, internal damp issues and long-term structural deterioration.
Correctly repointing a chimney stack helps restore the integrity of the masonry while improving resistance to weather exposure and extending the lifespan of the chimney.
Chimneys often show signs of deterioration long before major structural problems become visible.
Weathered or missing mortar allows water to penetrate deep into the chimney structure.
Failing joints can eventually cause bricks or masonry units to become unstable.
Damaged pointing can contribute to damp patches and moisture problems around chimney breasts internally.
Moisture trapped within failed joints can freeze and expand during colder months.
Older chimneys repaired with hard cement mortar may suffer accelerated brick deterioration.
Fresh repointing restores the appearance and definition of traditional chimney masonry.
Many older chimney stacks were originally built using lime mortar rather than modern cement-based mixes.
Lime mortar allows traditional masonry to breathe and release moisture naturally through the joints.
This flexibility is especially important for older chimneys exposed to constant weathering and thermal movement.
Using the correct mortar can help reduce stress within the masonry while protecting the surrounding brick or stone.
We inspect the condition of the chimney stack, mortar joints and surrounding masonry before recommending suitable repairs.
Defective mortar is carefully removed to minimise unnecessary damage to surrounding brick or stone.
Fresh mortar is applied and compacted correctly into the prepared joints using an appropriate finish.
The chimney is finished neatly and protected during curing where required.
Every chimney is different, which is why we tailor the repointing approach to suit the age, construction and condition of the masonry.
Our aim is always to provide sympathetic, durable repairs that help preserve the integrity and appearance of the chimney stack long-term.
If your chimney stack has open joints, failing mortar or visible weather damage, SGT Repointing Solutions can help restore and protect the masonry correctly.
