House Levelling in North Sydney
Modern Living. Classic Builds. Safe Foundations That Last.
From historic homes in Wollstonecraft to high-density dwellings near the CBD, North Sydney blends heritage charm with urban convenience. But under that mix of old and new lies a common problem—foundation movement. Tree root damage, reactive clay soil, and ageing subfloor systems can all cause homes in the area to shift, crack, or slump.
At Sydney House Levelling, we provide expert foundation repair and structural levelling for North Sydney homes. Whether you live in a federation cottage, a semi, or a newly built duplex, our team brings 20+ years of experience and a tailored approach to keep your home solid, safe, and structurally sound.
What We Fix in North Sydney Homes
- Sloping or uneven floors
- Internal or external wall cracks
- Doors or windows that jam or won’t close
- Gaps between floorboards and skirting
- Sagging or bouncy timber floors
- Signs of timber rot, termites, or stump failure
Many older North Sydney homes were built on timber stumps, brick piers or shallow footings—none of which were designed to withstand the ground movement we see today. If you’ve noticed any of the above signs, now’s the time to act.

Signs Your North Sydney Home May Be Moving
- Uneven or springy floors
- Cracks in walls, cornices or ceilings
- Windows or doors sticking
- Gaps between skirting boards and floor
- Brickwork or render cracking
- Sagging porches or footpaths
💡 These signs are more than cosmetic—get them checked before damage spreads.

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.
