With our expert team on your side, you can protect your home from the detrimental effects of subsidence and ensure it remains a safe, secure place for you and your family.

What is house subsidence?

House subsidence occurs when the ground beneath a building or structure shrinks or shifts, causing the building’s foundation to sink or tilt. This can lead to cracked walls, sinking floors, and other signs of structural damage. It’s a serious issue that needs immediate attention.

Signs of house subsidence

Recognising the signs early can save you from costly repairs in the future. Here’s what you need to look for:

Sinking or sloping floors

If your floors start to dip or slope, this could signify subsidence. Look for uneven surfaces or gaps between the floor and skirting boards.

Cracking walls

Cracks appear in walls, paths, and driveways due to the downward movement of the building foundation. The cracks are usually diagonal and wider at the top than at the bottom.

Sticking doors and windows

When the ground beneath your home shifts, it can cause your windows and doors to stick or jam. You might notice difficulties in opening and closing your windows and doors.

Uneven concrete driveways or patios

If the concrete slabs on your driveway or patio are uneven or have cracks, it could be a sign of subsidence.

Cracks in the foundation or basement walls

Cracks in your home’s foundation or basement walls clearly indicate subsidence. These cracks can allow water to seep through, leading to further complications like rising dampness.

Water seeping through the basement walls or floor

If water leaks into your basement, it could be due to cracks caused by subsidence. Addressing these issues promptly is crucial to prevent further damage to your property.

The dangers of house subsidence

Ignoring the signs of can lead to severe consequences. Unstable foundations can cause serious structural damage, making your home a safety hazard. Subsidence can also ruin your property, damaging driveways, patios, and landscaping. In extreme cases, subsidence can even lead to the collapse of a building, posing a significant risk to the occupants.

Preventing house subsidence

No one wants to deal with house subsidence and the serious damage it can cause. But don’t worry. There are steps you can take to reduce the risk.

Regular home maintenance and inspections

Regular upkeep of your home is a top priority. This doesn’t just mean a fresh coat of paint every few years. Look for signs of subsidence, like cracks in walls or uneven floors. Are doors or windows sticking more than usual? That could be a sign too.

If you live in an area with reactive soil or if your house has seen a few decades, consider getting a professional inspector involved. They can spot the signs you might miss and give advice on how to fix any issues.

Proper site drainage

Water build-up near your house’s foundation can be a big problem. It can make the soil soft and shift, moving your foundation. To stop this from happening, make sure your property has good drainage. 

A well-planned gutter system that sends water away from your house is necessary. And the ground near your house should slope away from the foundation. Don’t forget to check for leaks in your plumbing system and fix them quickly. They can make the soil unstable, too.

Consideration of soil type

The kind of soil your house is built on can make a big difference. Some soils, like reactive clay soils, can change size based on how wet or dry they are, which can move the ground. If your house is built on this soil, you should get professional advice on what to do. 

You could use deep pile foundations, stabilise the soil, or landscaping to keep the soil moisture levels steady.

Tree planting and management

Large trees near your house can cause subsidence because their roots pull water out of the soil. This can make the soil shrink and move. Think carefully about where you plant trees and how big their roots might get. 

Building design and construction

If you’re building a new home, make sure your team knows their stuff regarding local soil conditions. They can design and build your home to lessen the risk of subsidence. This might mean using certain foundations, construction materials, or building methods.
