Maintaining the stonework of older properties is crucial in preserving their beauty and structural integrity. As experts in pointing and restoration, we understand that time, weather, and wear can significantly impact stone buildings, leading to various issues that require attention.
By identifying these problems early on, property owners can prevent further deterioration and costly repairs, ensuring their property remains in good condition for years to come.
In this blog, we will guide you through the most common stonework issues seen in older properties and offer practical advice on identifying and repairing them. With regular maintenance and the right solutions, you can restore the strength and appearance of your stone structures.
Common Stonework Issues in Older Properties
One of the most frequent problems we see in older stone buildings is weathering due to prolonged exposure to the elements. Wind, rain, and fluctuating temperatures slowly erode the surface of the stone, leading to a loss of detail and texture.
This can be particularly damaging for heritage buildings, where intricate stone carvings and façades play an important role in the property’s overall aesthetic. Over time, weathering can also weaken the structure, making it more vulnerable to further damage.
Another prevalent issue is cracking, which may occur as a result of natural movement in the building’s foundation or structural shifts. Minor hairline cracks might seem harmless at first, but they can allow water to seep in, potentially leading to more serious structural damage over time. Larger cracks can indicate deeper issues that require professional assessment and intervention.
How to Identify Stonework Issues
Regular visual inspections are essential for spotting early signs of stonework problems. Look for surface erosion, cracks, and discolouration, particularly after extreme weather conditions. Weathered stone often appears smoother or more rounded, while cracks and gaps can be seen in mortar joints or along the surface of the stone itself.
Pay attention to any changes in the stone’s appearance, as these could indicate underlying issues.
Moisture monitoring is another effective way to identify potential problems before they escalate. Dampness can be a silent but significant threat to stonework, particularly in older properties.
Using a moisture meter to check for damp spots, especially around the base of walls and in areas prone to water exposure, can help you detect issues early. Addressing moisture problems promptly can prevent further stone damage and avoid expensive repairs in the future.
Repair Solutions for Common Stonework Issues
For stone buildings that have experienced mortar loss due to weathering or cracking, repointing with lime mortar is often the best solution. Lime mortar is a traditional material that allows stonework to breathe, making it ideal for older properties.
The process involves carefully removing damaged or deteriorated mortar and replacing it with fresh lime mortar. This not only restores the visual appeal of the property but also strengthens the structure and provides better protection against the elements.
When it comes to larger or structural cracks, crack injection is a reliable method. This process involves injecting a special resin or grout into the cracks, filling them and bonding the stone back together.
This technique is particularly useful for reinforcing the structure and preventing further cracking. By addressing the cracks early, you can avoid more extensive damage and ensure the longevity of the stonework.
Preventative Measures for Maintaining Stonework
In addition to repairs, regular maintenance and cleaning are vital for the long-term preservation of stone buildings. Keeping the stone free from dirt, moss, and other biological growth is essential, as these can trap moisture and lead to further damage.
Soft brushing and the use of appropriate cleaning agents will help maintain the stone’s natural beauty without causing harm.
Proper drainage systems are also crucial in preventing moisture-related problems. Water is one of the biggest threats to stonework, as it can lead to rising damp, efflorescence, and freeze-thaw damage.
By ensuring that your property has an effective drainage system in place, you can protect your stone walls from excessive moisture exposure and extend their lifespan.

While property owners can handle some minor stonework repairs, more serious issues should always be assessed by a professional. If you notice large cracks, significant erosion, or recurring moisture problems, it’s best to consult with an expert.
