House Levelling & Relevelling


If your home is sloping, doors are sticking, or cracks are forming in your walls, it may be time for professional house levelling. We restore your home’s position using precise methods tailored to the cause—whether that’s soil movement, failing stumps, or foundation wear. Every relevelling job begins with a detailed assessment and ends with long-lasting peace of mind.


House Relevelling Specialists


Old or damaged timber stumps can shift over time, causing floors to dip and frames to twist. We remove failing stumps and install strong, modern replacements—ensuring your home is safely supported and structurally sound for decades to come.

Re-Stumping


When foundations are no longer strong enough to support your home, underpinning adds the reinforcement needed to stabilise and secure your property. We use engineered solutions to extend your footing into stable soil and stop further movement.

Underpinning


For lighter structures or concrete slabs, resin injection is a fast, non-invasive way to stabilise sunken ground. This method lifts and strengthens foundations by injecting an expanding resin that fills gaps under the home—ideal for driveways, patios, and parts of the house affected by soft or shifting soil.

Foundation Repair Services


We inspect, repair, and upgrade the beams, bearers, and joists under your home to make sure everything’s structurally sound. If you’ve noticed bouncy or noisy floors, it might be time to look beneath the surface.


Sub-Floor Works


Ventilation

Moisture trapped under your home can lead to mould, timber decay, and structural problems. We install smart sub-floor ventilation systems that keep air moving and dampness out—helping protect your investment.

Rang Anthony after reading previous good reviews to look at some early damage and old piers. The team on site were great, on time, polite, cleaned up, took photos and were happy to show progress and talk me through their work. The outcome was better than expected and they fixed more problems than we realised were there. No more creaky floors! Fixed price. No surprises. Highly recommend them.

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? 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. Talk to Sydney’s House Leveling Experts We’ll inspect your home, explain your options, and recommend whether concrete or steel underpinning is best for you. 📞 Call us today to book an inspection and get a tailored solution for your Sydney home.

Noticed cracks in your walls? Doors sticking? Uneven floors? These are early signs of foundation problems—and if you delay repairs, you could be setting yourself up for bigger headaches (and costs) down the track. For Sydney homeowners, where reactive clay soils and changing weather conditions often cause foundation movement, underpinning can be the difference between a stable home and major structural damage.  Here’s why delaying underpinning repairs is never a good idea.
