How Can You Tell if It’s Subsidence?

It can be hard to tell the difference if you aren’t familiar with subsidence. Read on to learn more about subsidence and what you can do about it.

Common Signs of Subsidence

How can you tell if it's subsidence or just a normal crack? These are the most common signs of subsidence or settlement damage in residential properties.

Cracks in the Walls

Subsidence cracks are usually wider than 5mm. They are normally more diagonal and wider at the top; appearing suddenly in plaster work inside the building and on stucco or block outside.

Cracks in Driveways or Patios

One of the earliest signs of subsidence is often a crack in your driveway or patio where the area seems unlevel – especially if those cracks increase in width or length over time.

Cracks in Foundations

If you are remodeling or redoing floors, you may notice large cracks, unlevel areas of flooring, and other signs of subsidence in your concrete foundation – pay attention to changes over time.

Shifting or Sinking Floors

Floors can drop when subsidence or settlement has affected your home, you may notice gaps between the floor and the baseboard or changes in your tiles such as uneven tiles or new cracks in your tile.

Separation at Extensions

Many times, if you have an extension or add-on to your property, it will be the first part of your home to be affected. Subsidence cracks are common at points where an extension meets the main buildings.

Sticking Windows or Doors

Shifts due to weak foundation can put additional pressure onto openings like windows and doors, leading to uneven pressure that causes sticking, jams, and even cracking along door or window frames.

Is the Crack Bigger than a Pencil Eraser?

Cracks in the walls are one of the most obvious and common signs of subsidence. Not all cracks, however, are due to subsidence. Fine, hairline cracks are usually nothing to worry about. Subsidence cracks, on the other hand, are usually wider than 5mm - about the width of a #2 pencil. When cracks are caused by subsidence, they will normally be more diagonal and wider at the top. They tend to appear suddenly in plaster work inside the building and on stucco or block outside.
