When Do You Need Underpinning?

Not sure if your foundation needs underpinning?

Cracks in Walls or Foundation

Noticeable cracks in walls, particularly diagonal ones, or gaps in your foundation can signal subsidence or movement.

Uneven or Sunken Floors

Floor surfaces that slope or feel uneven may indicate part of the foundation is settling unevenly.

Doors and Windows Misaligned

When doors or windows jam or no longer sit properly in their frames, it could be due to foundation shifts.

Gaps Between Walls and Ceilings

Visible separations between the ceiling and walls or between skirting boards and floors can suggest structural movement.

Structural Movement in Sloped Blocks

Homes built on sloped land are especially prone to ground movement, increasing the need for underpinning.

Previous Foundation Repairs

If your property has a history of structural issues or patch repairs, a more permanent solution like underpinning may be required.

Underpinning FAQs

What is underpinning and why might my home need it?

Underpinning is the process of strengthening an existing foundation by extending it to a more stable level below the ground. Homes may need underpinning due to foundation movement, soil instability, age-related wear, or water damage. It helps prevent further structural damage and restores the home’s stability.

What are the signs that underpinning may be required?

Common warning signs include:

- Cracks in walls or ceilings
- Sinking or sloping floors
- Doors and windows that stick or don’t align properly
- Gaps between walls and flooring

If you notice these issues, it’s important to have your home assessed by a qualified professional.

How long does the underpinning process take?

The duration depends on the size of your property and the extent of the work needed. Most residential underpinning projects take between 1 to 3 weeks. After a site inspection, we’ll provide a detailed timeline tailored to your home.

Is it safe to stay in the house during underpinning?

In many cases, yes — you can remain in your home while work is carried out. However, for extensive projects or for safety reasons, we may recommend temporary relocation during certain phases. We’ll always discuss this with you in advance.

How much does underpinning cost in Melbourne?

Costs can vary depending on the type of foundation, soil conditions, and the number of underpinning points required. We offer free inspections and clear, upfront quotes so you know exactly what to expect.

Does underpinning increase my property value?

Yes. Underpinning improves the structural integrity of your home and can boost its value. It also reassures potential buyers that the foundation has been professionally stabilised and maintained.

How do I choose a reliable underpinning contractor?

Look for licensed and insured contractors with a proven track record and experience in local soil conditions. Ask about guarantees, request references, and ensure they provide a clear scope of work.
