What’s the Average Cost to Relevel a House in Sydney?

If your floors are sloping, your doors aren’t shutting properly, or cracks keep forming in your walls, you might be dealing with foundation movement. And while it’s something you’ll want to address sooner rather than later, most homeowners have one big question first: “How much is this going to cost me?”

The answer? It depends — but we’ll walk you through what affects the cost of house relevelling in Sydney , what you can expect to pay, and how to get the best value without cutting corners.

What Affects the Cost of Relevelling?

No two homes are the same, and neither are their foundations. The cost of relevelling will depend on a few key factors:

Type of foundation – timber stumps, concrete slab, brick piers, or a combination
Extent of movement – is it a minor dip or widespread sinking?
Number of stumps or footings that need replacing
Access – tight sites or steep blocks require more labour and time
Soil conditions – reactive clay, moisture levels, or erosion
Whether floor levelling or cosmetic repairs are needed afterwards

Average Costs Based on Foundation Type

Here’s a general breakdown of what homeowners in Sydney might expect to pay:

Partial restumping:$4,000–$8,000 for 10–20 stumps
Full restumping (standard home):$10,000–$20,000
Underpinning concrete slab:$2,500–$5,000 per pier
Floor levelling only:$1,500–$4,000 depending on material and area size
Relevelling on a sloped block:$12,000–$25,000 due to added engineering and access work

Note: These are average estimates and actual prices can vary based on site-specific factors.

What’s Included in the Price?

At Sydney House Leveling, our quotes are clear and comprehensive. A standard house relevelling job typically includes:

Full site inspection and level measurements
Supply and installation of new steel or concrete stumps
Jacking, lifting, and levelling the structure
Waste removal and cleanup
Post-work checks and structural integrity review

We’ll also flag any recommended drainage or ventilation upgrades that can help prevent future movement.

How to Save Without Cutting Corners

Relevelling is a specialist job — and it’s not one you want done twice. Here’s how to get the best value:

Get multiple quotes, but focus on experience and what’s included — not just price
Ask about materials(e.g. galvanised steel vs timber)
Check reviews or past projects before you commit
Fix early — smaller issues cost less to repair than major shifts

Is It Worth It?

Yes. Relevelling your home not only improves safety and comfort, it protects your asset. Left untreated, structural movement can lead to major repairs, unsafe living conditions, or difficulty selling the property later on.

It’s an investment in the long-term health of your home — and with the right team, it’s one that pays off.

Underpinning Explained: When Is It Necessary in Sydney?

August 22, 2025

Underpinning Explained: When Is It Necessary in Sydney? If you’ve noticed cracks in your walls, doors that don’t close properly, or uneven floors, your home’s foundation could be trying to tell you something. In Sydney, where many homes sit on reactive clay soils or older footings, foundation issues aren’t uncommon—and underpinning might be the solution you need. But what exactly is underpinning, and how do you know if it’s necessary for your property? Let’s break it down. What Is Underpinning? Underpinning is the process of strengthening and stabilising the foundation of an existing structure. It involves extending the foundation depth or spreading the load to more stable soil. This ensures that your home remains level, safe, and structurally sound for years to come. For Sydney homes, underpinning is commonly used in house leveling projects to correct subsidence (sinking or movement in the foundation). When Is Underpinning Necessary? Not every crack in your wall means you need underpinning, but here are key signs that suggest it might be time to call in the experts: 1. Significant Foundation Movement If your house has shifted or sunk noticeably, especially in areas with clay-rich or unstable soil, underpinning is often the best long-term solution. 2. Large or Widening Cracks Hairline cracks are normal, but wide cracks (5mm or more) in walls, ceilings, or brickwork indicate serious foundation movement. 3. Uneven or Sloping Floors If your floors slope or feel bouncy, your foundation may no longer be stable. 4. Doors and Windows Sticking When the foundation moves, door and window frames can warp, making them hard to open or close. 5. After Renovations or Extensions If you’re adding a second story or extending your home, underpinning may be required to ensure the foundation can handle the extra weight. Why Underpinning Is Common in Sydney Sydney’s mix of reactive clay soils, older homes, and variable weather conditions makes foundation movement a common issue. Droughts, heavy rainfall, and tree roots can all cause the soil to expand or contract, leading to subsidence. If your home is more than 30 years old or built on sloping ground, regular foundation inspections are a smart precaution. What Happens During Underpinning? The process typically involves: Assessment & Soil Testing – Engineers inspect the site and test soil conditions. Excavation – Sections under the foundation are carefully dug out. Concrete or Resin Injection – New footing material is added to strengthen and level the foundation. Monitoring – The foundation is checked for movement to ensure long-term stability. The exact method depends on your home’s construction and the severity of the issue. Do You Need Underpinning or Just House Leveling? Not all foundation problems require full underpinning. Sometimes, house leveling alone —lifting and adjusting the existing stumps or piers—can fix the problem at a lower cost. A professional assessment will determine whether house leveling or underpinning (or a combination of both) is the right approach. Talk to a Sydney House Leveling Expert If you’ve spotted any of the warning signs, don’t wait—foundation problems only get worse (and more expensive) over time. A professional house leveling and underpinning expert can inspect your property, explain your options, and recommend the best solution. Need help with your Sydney home’s foundation?

Concrete vs. Steel Underpinning: What’s Best for Sydney Homes?

August 18, 2025

Concrete vs. Steel Underpinning: What’s Best for Sydney Homes? When foundation issues strike, underpinning is often the best solution to stabilise and level your home. But which method should you choose— concrete underpinning or steel underpinning ? Both are effective, but the right choice depends on your home’s construction, soil type, and how severe the foundation movement is. Here’s a breakdown to help Sydney homeowners make an informed decision. Concrete Underpinning: The Traditional Choice What It Is Concrete underpinning involves digging under your existing foundation and pouring concrete to create a deeper, stronger footing. Pros Proven and Reliable – A traditional method with decades of successful use. Cost-Effective – Generally cheaper than steel underpinning for standard residential jobs. Great for Large Areas – Ideal for homes with widespread foundation movement. Cons Slower Installation – Excavation and curing take time, so the process can take weeks. Messy and Disruptive – Requires significant digging around your home. Not Ideal for All Soils – Less effective in very loose or sandy soils. Steel Underpinning: The Modern Alternative What It Is Steel underpinning uses screw piles or driven steel piers installed deep into stable soil or bedrock, then attached to the foundation to lift and support the home. Pros Faster Installation – Can be completed in days, not weeks. Minimal Excavation – Less disruptive to gardens and landscaping. Ideal for Problematic Soils – Works well in Sydney’s reactive clay and sloping blocks. Immediate Load-Bearing – No waiting for concrete to cure. Cons Higher Cost – Steel is generally more expensive upfront. Not Always Necessary – Overkill for minor subsidence issues. Which Is Best for Sydney Homes? Both methods work, but here’s a quick guide: Choose Concrete Underpinning if… ✔ Your home has widespread subsidence or needs a large foundation area reinforced. ✔ You’re on a tighter budget and don’t mind a longer project timeline. Choose Steel Underpinning if… ✔ You’re on reactive clay soil (common in Western Sydney). ✔ Your home is on a sloping block or needs deep stabilisation. ✔ You want a fast, less disruptive solution . In many cases, engineers may recommend a combination of both methods, depending on your property’s unique conditions. Need Expert Advice? Choosing the wrong underpinning method can cost you more in the long run. If you’re noticing cracks, uneven floors, or doors sticking , it’s time to have your foundation professionally assessed.
