Unearthing the Truth About Subsidence: A Comprehensive Guide for UK Property Buyers

Understanding Subsidence

Subsidence is a term that can strike fear into the hearts of homeowners and property investors alike. It refers to the gradual sinking or downward settling of a building’s foundation, often caused by changes in the soil beneath it. This can lead to significant structural damage, from minor cracks in walls and floors to severe structural instability.

Subsidence is a common issue in the UK, particularly in areas with clay soil, which is prone to shrinking and swelling with changes in moisture levels. However, it can occur anywhere, and all types of properties can be affected, from historic buildings to modern homes.

Identifying Subsidence: Active or Historic?

One of the key challenges with subsidence is determining whether it is active or historic. Active subsidence means the property is currently experiencing movement, while historic subsidence indicates that while there has been movement in the past, it has since stabilised.

Signs of active subsidence can include new or expanding cracks in walls, doors or windows that stick and are difficult to open, and uneven floors. Historic subsidence, on the other hand, may leave signs such as old, filled-in cracks that have not changed in size or shape for a long time.

However, it’s important to note that not all cracks indicate subsidence. Small cracks are common in buildings and can be caused by a range of factors, including normal settling and changes in temperature. Therefore, if you notice cracks in a property, it’s crucial to seek professional advice to determine the cause.

Dealing with Subsidence

If you suspect a property has subsidence, the first step is to have a thorough building survey conducted by a professional surveyor. They can assess the property and determine whether subsidence is a concern, and if so, whether it is active or historic.

If active subsidence is identified, the next step is usually to determine the cause. This could involve further investigations, such as a soil investigation or drainage survey. Once the cause is identified, appropriate treatment can be recommended.

Treatment for subsidence can vary depending on the cause and severity. In some cases, simple measures such as removing vegetation close to the property or repairing leaking drains may be sufficient. In more severe cases, underpinning – a process of strengthening the property’s foundations – may be required.

Protecting Your Investment

Subsidence can be a daunting issue for property buyers, but with the right knowledge and support, it doesn’t have to be a deal-breaker. By understanding what subsidence is, how to identify it, and how to deal with it, you can make informed decisions and protect your investment.
