Property Subsidence in London: What You Need to Know
Subsidence is a common problem in London, and it can have a significant impact on homes and businesses. If you’re buying or selling a property in London, it’s important to understand what subsidence is, how it can affect your property, and what you can do to protect yourself.
What is subsidence?
Subsidence is the downward movement of the ground beneath a building. A number of factors, including these, can cause it
- Shrinking soil: London is built on clay soil, which can shrink when it dries out. This can cause the ground beneath buildings to move, leading to subsidence.
- Vibrations: Subsidence can also be caused by vibrations from nearby construction, traffic, or other activities for example.
- Mining: In the past, London was a major center for mining. This activity can cause subsidence, even many years after the mines have been closed.
What are the signs of subsidence?
The most common sign of subsidence is cracks in walls, ceilings, or floors. Other signs of subsidence may include:
- Doors and windows that no longer close properly
- Uneven floors
- Leaning trees or other structures
- Water pooling on the ground
If you notice any of these signs, it’s important to have your property inspected by a qualified surveyor.
How can I protect my property from subsidence?
There are a number of things you can do to protect your property from subsidence, including:
- Have your property surveyed: A qualified surveyor can identify any potential problems with your property and recommend ways to mitigate the risk of subsidence.
- Plant trees and shrubs away from your property: Trees and shrubs can remove moisture from the soil, which can increase the risk of subsidence.
- Keep your gutters and drains clear: Clogged gutters and drains can cause water to pool on the ground, which can also increase the risk of subsidence.
- Avoid building on or near unstable ground: If you’re planning to build a new home or add an extension to your existing home, it’s important to have the ground tested to make sure it’s stable.
What if my property has subsidence?
If your property has subsidence, it’s important to act quickly to prevent further damage. A qualified surveyor can recommend the best course of treatment, which may include:
- Injections: This involves injecting a substance into the ground to stabilize it.
- Piling: This involves driving piles into the ground to provide support for the building.
- Reinforcement: This involves strengthening the building’s foundations.
Subsidence can be a costly and disruptive problem, but it’s important to remember that it’s often preventable. By taking steps to protect your property, you can help to avoid the financial and emotional stress of dealing with subsidence.
