Few issues are as concerning when it comes to protecting your home as subsidence. This unsettling phenomenon can lead to serious structural damage, affecting not only the stability of your property but also its value and your peace of mind. For homeowners, it’s crucial to recognise the signs of subsidence and understand how to address it through subsidence claims.

In this guide, we’ll cover everything you need to know about subsidence claims, including common causes and signs, practical prevention tips, and how to navigate the insurance claims process.

Whether you’re looking to prevent subsidence or already facing a subsidence issue, this article will provide the insights necessary to protect your property and manage your claims effectively.

FAST FACTS: Subsidence Claims

Subsidence Claims Statistics

  • Increase in Claims: In 2022, there were approximately 23,000 subsidence claims, with 18,000 of these occurring in the latter half of the year, correlating with a severe summer heatwave. This trend indicates a growing concern among homeowners regarding subsidence, particularly in heat-affected areas.
  • Payouts: The Association of British Insurers reported that £782 million was paid out in home insurance claims during the second quarter of 2023, marking an 11% increase compared to the same period in 2022.
  • Claim Validity: Recent findings from the Claims Consortium Group revealed that only one in three subsidence claims submitted over recent years were found to be genuine, suggesting a need for more rigorous assessment processes by insurers.

Future Predictions

  • Climate Impact: Experts predict that the areas affected by subsidence could double by 2050 due to climate change, emphasising the need for insurers to adapt their models and strategies accordingly. The insurance sector is urged to utilise predictive modelling to better manage risks associated with climate change and its impact on properties.

Understanding Subsidence and its Implications

Subsidence refers to the downward movement of the ground supporting a building, leading to structural damage. It often manifests as sinking or settling soil beneath foundations, impacting property stability and insurance considerations. Timely intervention is essential, as insurers carefully assess properties with a history of subsidence, which affects premiums and coverage terms. Knowing about subsidence and handling claims is invaluable for maintaining your property’s value and ensuring comprehensive insurance coverage.

What Causes Subsidence?

Subsidence can result from many factors relating to your property’s soil type and environmental conditions. Understanding these causes is crucial for taking preventative action.

Soil Composition and Moisture

Soil type is a primary contributor to subsidence. Clay soils are especially prone to shrinking and swelling with moisture changes. During dry periods, clay contracts, causing subsidence, while it expands during wet conditions, potentially leading to heave (an upward ground movement).

Natural Vegetation

Another significant cause of subsidence is the presence of natural vegetation. Tree roots near buildings absorb significant soil moisture, which can increase shrinkage risk, especially in clay-heavy soils. Properties with large trees nearby may experience greater subsidence risk due to these water-demanding root systems.

Human Activities

Human activities such as poor drainage, water leaks, and historical mining can also worsen subsidence issues. Leaking drains or plumbing can saturate and weaken the soil, triggering subsidence. Similarly, previous mining activities often leave voids that pose subsidence risks for properties built above them.

Recognising the Signs of Subsidence

Identifying subsidence early can help prevent extensive damage and costly repairs. Here are the primary signs of subsidence to watch for:

  • Cracks in Walls: Subsidence cracks are often diagonal or zig-zagged, larger than typical settlement cracks, and may radiate from windows or doorways.
  • Sloping or Uneven Floors: Floors that appear uneven or sloping could indicate foundation and subsidence issues.
  • Misaligned Doors and Windows: Subsiding ground can cause doors and windows to stick or no longer close correctly.

By recognising these signs of subsidence, you can take prompt action to mitigate further damage, preserving your property and its value. Distinguishing between minor settlement and serious subsidence is crucial for addressing issues effectively.

Prevention Tips for Reducing Subsidence Risk

Although not all subsidence can be prevented, proactive measures can significantly reduce your property’s risk. Here are some key steps you can take.

Vegetation Management

One essential strategy is managing vegetation around your home. Avoid planting trees with high water demand near foundations, and consider root barriers to protect your property from invasive root systems.

Home Maintenance and Drainage

Regular home maintenance, such as inspecting and repairing drainage systems, helps maintain soil integrity. Proper soil grading around your foundation can also direct water away from your property, reducing the risk of soil saturation and subsidence.

Foundation Inspections

Addressing minor foundation issues promptly can prevent them from escalating into significant problems. Regular inspections and maintenance can identify potential risks early, enabling you to take corrective actions before substantial damage occurs.

The Role of Insurance in Managing Subsidence Claims

Insurance plays a crucial role in managing subsidence risks, but standard home insurance policies often exclude coverage for subsidence claims. Consider the following key steps:

  • Review Your Policy: Confirm what subsidence coverage your policy includes, and consider purchasing additional subsidence or mine subsidence coverage if needed.
  • Understand Exclusions: Be aware of limitations in your policy, such as exclusions for soil shrinkage or groundwater issues.
  • Communicate with Your Insurer: If you suspect subsidence, promptly inform your insurance provider to discuss your coverage and file a subsidence claim.

With adequate subsidence insurance coverage, you’re better protected against the financial impact of subsidence claims. Maintaining open communication with your insurer and understanding your policy’s limitations is essential for safeguarding your investment and addressing potential subsidence claims effectively.

A Step-by-step Guide for Subsidence Claims Process

If you notice any signs of subsidence and need to file a claim, following the correct process can help improve the outcome. Here are the key steps involved in making a subsidence insurance claim.

Inform Your Insurer

Contact your insurer when you notice any subsidence signs, initiating a formal claim. Early notification ensures that your case is documented and prioritised for assessment.

Collect Evidence

Collect photographs of the damage, assessment reports, and other evidence to support your claim. This evidence helps to substantiate the claim and clarify the extent of damage.

Hire a Surveyor

An expert surveyor can objectively evaluate the damage’s extent, adding credibility to your claim. Their assessment is often essential in cases involving subsidence.

Work with a loss assessor

A loss assessor can help with subsidence claims, as they can liaise with your insurer to assess damage and determine compensation. To facilitate a fair settlement, maintain clear communication, provide requested information promptly, and keep detailed records of interactions

By following these guidelines, you can streamline your subsidence claims process, increasing the chances of a positive outcome while minimising potential delays.

Options for Fixing Subsidence Damage

Once subsidence is identified, selecting the right repair method depends on the severity and underlying cause of the issue. Here are some commonly used repair options.

Underpinning for Severe Subsidence

Underpinning, which involves reinforcing the foundation, is a common technique for addressing significant subsidence. This method stabilises the property by strengthening the foundation base.

Resin Injection for Minor Subsidence

For less severe cases, resin injection can stabilise the soil by filling voids, offering a less invasive solution for minor subsidence. This technique is often more affordable and faster than underpinning.

Each repair method varies in cost and long-term effectiveness, impacting property value and stability. Evaluating the nature of the subsidence and consulting with professionals can help determine the best approach for your situation.

Buying, Selling, and Living in a Property with Subsidence

Living in or dealing with a property affected by subsidence presents unique challenges, particularly when buying or selling. A history of subsidence can influence the property’s market value and complicate transactions. Buyers should conduct thorough inspections, and sellers should provide detailed records of repairs and mitigation measures undertaken.

Understanding the insurance implications of owning a subsidence-affected property is crucial for protecting your investment. Ensuring continuous coverage and awareness of potential policy exclusions can safeguard against unexpected financial burdens. subsidence claims
