What is the cracking in my house?

When you notice cracks in your house, it's natural to feel concerned. Cracks can be cosmetic, a sign of normal settling, or indicators of more serious structural issues such as subsidence. Understanding the cause and knowing when to seek professional help is crucial for maintaining your property's health and value. In this article, we'll explore the causes of cracking, the signs of subsidence, and how to address these issues effectively. Whether you're a DIY enthusiast or a prospective homebuyer, it's important to be informed about the risks you may face.

What is causing the cracking in my house?

Cracks in your house can arise from a variety of sources. Common causes include:

Thermal Movement: Changes in temperature can cause materials to expand and contract, leading to cracks.
Subsidence: This occurs when the ground beneath your home shifts or sinks, removing support from the building's foundations.
Settlement: Newer buildings may experience settling in the first few years after construction, causing minor cracks.
Structural Overloads: Adding weight, such as a new roof, without proper support can lead to cracking.
Moisture Changes in Soil: Excessive moisture or drying out of the soil beneath the foundations can cause movement and cracking.

Is a property survey needed if my house is cracking?

Yes, a property survey is highly recommended if you notice cracking in your house. A professional survey can help determine the cause of the cracks and the extent of any underlying issues. It's especially crucial if the cracks are sudden, widening, or accompanied by other signs of structural problems. Early detection through a survey can prevent more serious and costly repairs in the future.

What are the signs of subsidence?

Recognizing the signs of subsidence early can save you from significant damage down the line. Key indicators include:

Cracks that are diagonal, wider than 3mm, and visible from both inside and outside of the property.
Cracks that are near doors and windows or where an extension joins the main building.
Doors and windows that stick or don't close properly.
Visible gaps under the base of exterior walls.

How to fix property subsidence?

Fixing property subsidence varies with the severity and cause of the issue. Methods include:

Underpinning: Strengthening the foundation by extending it deeper into the ground.
Mass concrete underpinning: Adding more concrete to the foundation to provide additional support.
Resin injection: Injecting a resin into the soil to increase its strength and stability.

Each method requires a detailed assessment by a professional to ensure the most effective solution is applied.
