We provide fast, council-compliant foundation repair services to protect your home and property — call 1300 970 930 to speak to Chris for a site inspection.
We are Underpinning Sydney, structural preservation specialists with 20+ years’ experience. Our team restores safety with engineered underpinning, resin injection, screw piling and wall crack repairs.
Many older Sydney buildings sit on clay soils that shrink and cause settlement. We assess the foundation and recommend staged excavation, pinning and propping where needed.
Safety and certification matter. We use licensed, insured methods, provide fixed-price quotes and coordinate engineering reports for council approval.
Expect minimal disruption and clear advice. Book a free, no-obligation structural assessment or email photos for a quick preliminary review.

Clear signs your Leichhardt home may need underpinning or foundation repair
Small changes around the home can signal that the foundation needs attention. Spotting issues early lets us protect your building and avoid larger costs later.
- Diagonal cracks in brickwork or plaster that grow wider over time.
- Floors that bounce, slope or have tiles that crack or de-bond along lines.
- Doors and windows sticking, or gaps appearing at skirtings and ceilings.
- Retaining walls that lean or show visible movement.
- Localised damage near corners or additions indicating differential movement in foundations.
These are practical signs, not a diagnosis. We recommend a prompt professional check so you can make informed choices.
Early intervention preserves structural integrity. If you notice any of these signs at your house, call 1300 970 930 to speak to Chris for a no‑obligation site visit. For a quick review, you can also email photos or request a free preliminary foundation assessment.
What’s causing the damage: clay soils, ageing footings and water issues in the Inner West
Understanding what drives foundation movement helps you choose the right engineered repair. We explain local causes simply so you can act early.
Shrinking and sinking clay soils leading to settlement
Many older Sydney houses sit on clay that shrinks in dry spells and swells when wet. This change in volume shifts the support under a building and causes settlement.
Older brick footings, poor subfloor ventilation and drainage risks
Older brick footings are less robust than modern concrete. Poor ventilation and drainage keep the subfloor damp and soften nearby soil, increasing the risk of movement.
- Inner West clay soils change with moisture and move foundations.
- Tree roots can draw moisture from clay, worsening settlement.
- Damage often shows where loads change, like extensions or corners.
- We diagnose causes before recommending any underpinning or repair.
- Properly designed foundation works stop the cycle by re-levelling, propping and improving subfloor airflow.
| Cause | Effect | Typical Repair |
|---|---|---|
| Clay soil movement | Settlement and cracking | Pinning to rock, re-levelling |
| Tree roots | Local moisture loss and subsidence | Root management and soil stabilisation |
| Poor drainage/ventilation | Softened soil, ongoing movement | Drainage upgrades and subfloor vents |
Early diagnosis matters. We identify the root cause, then specify engineered solutions so your home remains stable long term.
Underpinning Leichhardt services tailored for safety and peace of mind
Our team delivers engineered foundation solutions that focus on safety and long-term stability.
Concrete underpinning to solid rock for lasting stability
Concrete underpinning uses staged hand excavation and poured underpins to reach solid rock beneath critical wall lines.
We prop and re-levelling as required under engineering direction to restore levels and stop further movement.
Resin injection for targeted ground improvement
Resin injection is a low‑impact solution for localised weak zones. It densifies soil without large excavations.
This method suits properties where access is limited and fast stabilisation is needed.
Screw piling where access is tight or loads are higher
Screw piling provides deep support for higher loads or cramped sites. It is staged and engineered for safety.
We use this where traditional concrete footings are impractical.
Wall crack repairs, subfloor ventilation and retaining wall support
After stabilisation we complete wall crack repairs and reinstate finishes so your walls look and perform well.
Subfloor ventilation and drainage upgrades reduce soil softening and lower the chance of repeat movement.
- House relevelling is done where safe and specified by the engineer.
- Retaining wall support restores lateral stability for landscape and boundary walls.
- Each solution is engineered, certified and documented for council compliance.
| Service | When used | Benefit |
|---|---|---|
| Concrete underpinning | Settlement under load-bearing walls | Permanent support to rock and level restoration |
| Resin injection | Local voids or soft zones | Minimal excavation and quick stabilisation |
| Screw piling | Tight access or high loads | Deep, staged support with less excavation |
| Wall crack repairs & vents | Visible cracks and damp subfloor | Close movement paths and reduce recurrence |
How we underpin: compliant methods that protect your structure
We follow a clear process that keeps your building supported while permanent repairs are installed. Our approach prioritises safety, staging and engineering oversight so you can be confident in the outcome.
Step-by-step hand excavation and staging to maintain support
We excavate by hand in short stages. Each pit is monitored and left supported so your home stays safe at all times.
Pinning to rock, propping and careful re-levelling
Foundations are pinned to rock with engineered details to secure the structural foundation. Temporary propping and measured re-levelling follow the engineer’s specifications.
Engineering report coordination and certification
We coordinate structural engineering reports and provide all council-ready certificates. Licensed, insured contractors deliver the works to recognised standards.
Minimal disruption, clean sites and neighbour-friendly works
Our team keeps the site tidy and respectful. You receive a clear program, daily safety checks and a final walkthrough so you understand the completed project.

Pricing, timeframes and what affects your project cost
Clear pricing and realistic timelines help any homeowner plan with confidence when structural work is needed.
We only prepare fixed-price quotes after a detailed site assessment. The inspection lets us measure the foundation, identify damage and note site risks that shape the scope.
Transparent fixed-price quotes after a detailed site assessment
After inspection you receive a written quote showing methods, inclusions and any contingency. This removes surprises and shows when we start and when we expect to finish.
Access, soil conditions, scope and chosen solution impact time and cost
Costs vary with the size of the building section, soil profile and the chosen underpinning solution. Access constraints or heritage fabric can extend the program.
- We only quote after inspecting your home and foundation conditions.
- You receive a transparent, fixed-price quote with clear inclusions.
- Access, clay soil profile and chosen method influence time and cost.
- Larger sections or staged projects take longer to complete safely.
| Factor | Effect | Typical outcome |
|---|---|---|
| Access | Limits machinery | Longer time, different method |
| Soil profile | Variable support | Additional stabilisation works |
| Heritage or live-in | Careful sequencing | Extended program, protection measures |
We flag any site-specific risk that could affect program or contingency. Call 1300 970 930 to arrange your assessment and fixed-price quote, or see our underpinning cost guide for initial guidance.
Local knowledge matters: Inner West conditions and typical projects
Our local team knows the Inner West streets and the patterns that affect old houses. We work across nearby areas such as Leichhardt, Annandale and Lilyfield. This helps us spot common issues quickly.
Heritage house fabric needs careful, low‑impact sequencing. Brick footings and original timber floors can be fragile. We protect original features while we stabilise foundations.
Soils, tree roots and typical scopes
Clay soil and mature tree roots drive many foundation movement problems. These forces cause settlement, cracks and uneven floors in older buildings.
Typical local projects include re‑levelling, pinned footings to rock, crack stitching and targeted repairs. We also upgrade ventilation and drainage to reduce future risk.
- We know narrow access and shared walls common in these areas.
- Our methods suit tight sites and sensitive heritage fabric.
- You get practical advice tailored to your house and surrounding soil.
