What Causes a Home to Shift and Require Levelling

• Shifting Soil Conditions

Changes in soil moisture, such as expansion during wet seasons and contraction during dry periods, can lead to foundation problems and uneven settling.

• Poor Drainage Around the Property

Inadequate drainage causes water to pool near the foundation, weakening the soil and leading to signs foundation is sinking.

• Tree Roots and Vegetation

Large tree roots growing near the home can displace soil, affecting the stability and requiring house levelling in Adelaide.

• Improper Construction Practices

Using substandard materials or failing to compact the soil properly during construction can result in the need for levelling property over time.

• Natural Ground Movement

Earthquakes, erosion, or even minor ground shifts can create warning signs your property needs house levelling, such as cracks or sloping floors.

DIY Ways to Check for House Levelling Issues

1. Use a Bubble Level for Simple Checks

Place a bubble level on the floor in multiple areas; uneven readings may indicate foundation levelling is required.

2. Roll a Ball to Spot Slopes

Place a golf ball or marble on hard floors; if it rolls consistently in one direction, it’s a sign your home may need house foundation repairs.

3. Measure with a Water Level for Precision

A clear plastic tube filled with water can help you compare floor heights across different points, revealing areas that need attention.

4. Inspect Door and Window Alignment

Doors or windows that stick or don’t close properly can be warning signs your property needs house levelling.

5. Use a Laser Level for Comprehensive Checks

Set up a laser level to project a horizontal line and measure variations in floor height, helping you identify uneven areas effectively.

5 Warning Signs Your Property Needs House Levelling

✔ Uneven or Sloping Floors

If furniture leans or a ball rolls on its own, it’s a clear sign that your floors are no longer level and may require professional attention.

✔ Cracks in Walls or Ceilings

Diagonal or widening cracks, especially in brickwork or plaster, often indicate underlying foundation issues that need immediate inspection.

✔ Sticking Doors and Windows

When doors and windows become difficult to open or close, it could be due to structural movement affecting their frames.

✔ Gaps Between Walls and Floors or Ceilings

Noticeable gaps where walls meet floors or ceilings, or skirting boards pulling away, are common signs of foundation movement.

✔ Exterior Structural Issues

A leaning chimney, cracks in exterior brickwork, or gaps around window and door frames suggest your property may need house levelling.
