What to look out for when winter strikes your stonework

The UK’s characteristic mix of wind, rain, and snow can make for chilly, soggy winters — not to mention posing significant challenges for architectural stone structures. From erosion to cracking, winter weather can wreak havoc on these buildings, making preparation essential.

Whether you’re a homeowner or a property manager, safeguarding your architectural stone is crucial for its longevity and beauty. This article explores how winter conditions can damage stone structures, with valuable tips for preparing and addressing issues when winter strikes.

The effects of winter weather on natural stone

Architectural stone, while durable, is not immune to the effects of harsh winter weather. Wind, rain, and snow can all cause various forms of damage to stone structures over time.

Wind: Strong winds can erode the surface of stone through abrasion, especially when carrying particles like sand or debris. Additionally, high winds can cause structural stress on buildings, leading to cracks or displacement of stone elements.

Rain: Excessive rainfall can saturate stone, leading to water penetration and the deterioration of mortar joints. Over time, wet conditions can weaken the structural integrity and contribute to issues such as staining and salt deposits, known as efflorescence.

Snow: Snow accumulation on rooftops and ledges can add significant weight to stone structures, potentially causing structural damage or collapse if not properly managed. Additionally, freeze-thaw cycles can occur when snow melts and refreezes, leading to expansion and contraction that can further damage stone surfaces.

Tips for preparing buildings

To minimise the impact of winter weather on architectural stone and natural stone walling, it’s essential to proactively prepare buildings for the season ahead. Here are five tips to consider:

1. Inspect for damage: Conduct a thorough inspection of your stone buildings to identify any existing damage or areas of concern — ideally before inclement weather occurs. Look for cracks, loose stones, and signs of water damage.
2. Repair mortar joints: Check that mortar joints are in good condition by repointing any areas where mortar has deteriorated. This step will help prevent water infiltration and protect the structural integrity of the building.
3. Seal stone surfaces: Apply a suitable stone sealer to exterior surfaces to help repel water and protect against staining. Sealing will also make it easier to clean and maintain the stone.
4. Clear drainage systems: Keep gutters, downspouts, and drainage channels free of debris to ensure proper water drainage away from the building. Maintaining proper drainage will help prevent water from pooling around the foundation and causing damage.
5. Protect vulnerable areas: Consider installing snow guards on rooftops and ledges to prevent snow accumulation and reduce the risk of structural damage.

Despite your best preparation efforts, winter weather can still take its toll on natural stone. If you notice any damage to your stone buildings during winter, address it promptly to prevent further deterioration. Here’s what to do:
