Cracks in walls, doors that stick, or uneven floors — they might seem like small problems, but sometimes they point to a much bigger issue: subsidence. For homebuyers, spotting these signs early can make all the difference between a confident purchase and a costly repair later on.
At WR Surveying, we regularly inspect properties across the East Midlands where movement or ground instability is a concern. Here’s what you need to know about subsidence, what to look out for, and when to call a structural engineer.
What Is Subsidence?
Subsidence occurs when the ground beneath a building begins to sink or shift, causing the foundations to move unevenly. As the structure settles into these changes, visible cracks or distortions can appear in walls, floors, and door frames.
It’s one of the more serious structural issues a property can face, but not every crack means subsidence. The key is recognising the difference between normal settlement and active structural movement.
Common Signs of Subsidence
While no two properties are the same, there are several typical indicators that surveyors look for when assessing movement. If you notice one or more of these, it’s worth arranging a professional inspection:
- Diagonal cracks in walls: Usually wider than 3mm and visible both inside and outside, often extending from window or door corners.
- Gaps between walls and skirting boards: A sign that floors and walls are no longer moving together as they should.
- Windows or doors that stick: Changes in frame alignment can occur as the building shifts, making them harder to open or close.
- Uneven floors: Sagging or sloping floors may indicate that the foundation beneath part of the building has dropped.
- Cracks where extensions join: Movement at connection points between newer and older sections of the property is common in cases of subsidence.
Surveyors don’t rely on one symptom alone — we look at patterns, positioning, and context to determine whether cracks are historic, cosmetic, or still active.
What Causes Subsidence?
Several factors can lead to subsidence, and identifying the cause helps determine the best solution. The most common causes we see across Derbyshire, Leicestershire, Nottinghamshire, and Staffordshire include:
- Shrinking clay soil: During dry weather, clay soil contracts and pulls away from the foundations, creating gaps and instability.
- Tree roots: Large trees or shrubs close to the property can draw significant moisture from the ground, especially on clay soils.
- Drainage leaks: Damaged pipes or poor surface drainage can wash away supporting soil beneath foundations.
- Historic mining or ground disturbance: In some areas, old mine workings or filled land can lead to uneven settlement over time.
In many cases, subsidence is manageable if caught early. The key is accurate diagnosis.
Should You Still Buy a Home with Subsidence?
Discovering subsidence doesn’t necessarily mean you should walk away. Many affected homes can be repaired, stabilised, and insured — but only once the full extent of the issue is understood. That’s where a professional RICS survey makes the difference.
Our reports provide clear guidance on the severity of the movement, the likely causes, and realistic next steps. This information allows you to make an informed decision, negotiate on price, or plan for remedial works if needed.
How WR Surveying Can Help
Our surveyors have experience assessing structural movement and identifying early signs of subsidence. If movement is confirmed, a specialist subsidence surveyor can diagnose the cause and set out what the repair involves. We provide clear, evidence-based reports — complete with photographs, moisture readings, and professional recommendations — so you know exactly where you stand.
Whether you’re concerned about cracks in your walls or you’ve been advised to get a second opinion, we’re here to help you move forward confidently.
