House Levelling in Petersham
Old-World Homes. Shifting Ground. Expert Foundation Repair.
From brick Federation semis to weatherboard workers’ cottages, Petersham’s homes are full of history—but many are also sitting on ageing subfloors and reactive clay. Over time, that can mean sloping floors, jammed doors, and cracks that won’t go away.
At Sydney House Levelling, we specialise in structural repair solutions for Petersham homes—whether you’re dealing with movement in an old pier-and-beam foundation or a sunken slab in a modern extension. With 20+ years of experience and a deep understanding of Inner West soil and housing stock, we get the job done right.
Why Petersham Homes Need Levelling
The mix of heritage architecture and shifting soil makes Petersham one of Sydney’s higher-risk suburbs for foundation movement. Common causes include:
- Shrinking and swelling of clay-based soil
- Deteriorating timber stumps in older homes
- Water damage from poor drainage or leaking plumbing
- Invasive tree roots disturbing footings
- Substandard footings in older extensions or renovations
Fixing the root cause early saves money and keeps your home safe.

Common Signs of Structural Movement in Petersham
- Cracks in brickwork or around door frames
- Doors or windows sticking or misaligned
- Sloping or soft-feeling floors
- Gaps between walls and skirting
- Separation in ceiling cornices or tiles
- Wobble in verandahs, stairs or subfloor supports
💡 If your home shows any of these, don’t wait—get a professional diagnosis.

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.
Resin Injection
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.
