what do subsidence cracks look like

Subsidence is a problem that effects a surprisingly large number of people in the UK, with 1 in 5 properties believed to be at risk of the serious damage that subsidence can cause. 

If you think that your home is starting to show the signs of subsidence and you’ve found yourself asking the question ‘what do subsidence cracks look like?’, then you probably never expected to find yourself in such a situation.

As subsidence is a problem that needs to be addressed quickly, our guide is here to walk you through the essentials of subsidence, with everything you need to know about the cause, the signs, the remedy and prevention…

What is the Cause of Subsidence?

Subsidence is a problem that happens when the ground below a property starts to sink, or in some very serious cases, completely collapse. The effect that this has on the property above can range from minor to severe, with serious cases seeing the foundations of a building sinking also.

The causes of subsidence are varied, and depending on where you live in the UK and the layout of your garden, you may be more at risk of some causes that others. Some of the most common causes, include:

  • Trees planted too closely to a property
  • Leaking gutters
  • Homes built on clay soil
  • Mining in the local area
  • Poor drainage
  • Hot weather
  • Homes with shallow foundations

Subsidence cracks can also be identified by the diagonal shape that they form on the wall. If the width of the crack is smaller at the bottom than it is at the top, then there is a very good chance that the crack is due to subsidence.

Subsidence Cracks: How to Spot Them

The cracks that can form from subsidence are often quite easy to identify, as they can look very different to the hairline or fine cracks that most properties are prone to.

You’ll often find that subsidence cracks are at least 3mm thick, which is about 3x the size of a standard fine crack that can be caused by a property settling. A subsidence crack is also normally visible from the inside of a property as well as the outside.

Where Are Subsidence Cracks Most Likely to Appear?

Cracks caused by subsidence are unlikely to appear all over the exterior of your walls. An easy way to identify whether a crack is caused by subsidence is to see where it’s located.

Subsidence cracks are very common around the windows and doors of a property. If you have an extension on your home, then the area around where the extension connects with your home is also a good place to look for signs of subsidence cracks.

In all cases of suspected subsidence, it’s essential that you consult the experts who will be able to perform a full inspection of your property and monitor the situation

Fixing Subsidence Problems

Depending on the extent of your subsidence problems, the remedy will vary. For small cracks in the wall it can sometimes be possible to just fill them in and paint over them.

However, for larger cracks more extensive repair work will be required and potentially even foundation work to re-secure your home. 

How to Prevent Subsidence: 5 Top Tips

If your home is at risk of subsidence, and you’re starting to see the signs then it’s crucial to start making changes to prevent serious subsidence problems from occurring. Even if your home is not suffering from subsidence, prevention methods are still important to implement. 

There are a number of ways that you can prevent subsidence, including:

  • Regularly clean your guttering
  • Make sure water is draining away from your home
  • Keep new trees a good distance away from your home, and properly care for existing shrubs
  • Monitor the cracks in your wall 
  • React quickly to any signs of subsidence
