House Levelling in Narrabeen
Water Views. Sloping Blocks. Structural Peace of Mind.
Whether you're living beachside on Ocean Street or tucked into the hillside overlooking Narrabeen Lagoon, homes in this coastal suburb face unique foundation challenges. Sand-based soils, constant moisture, and ageing timber stumps all contribute to structural movement.
At Sydney House Levelling, we help Narrabeen homeowners protect and stabilise their properties—whether you’re in a classic fibro, weatherboard cottage, or multi-level modern build. With over 20 years of hands-on experience, we bring engineered, clean, and long-lasting foundation repair solutions to the Northern Beaches.
What We Fix in Narrabeen Homes
- Uneven, sagging, or bouncy floors
- Cracks in plaster, brickwork, or tile grout
- Stuck windows and jamming doors
- Gaps between cornices, walls, and skirting
- Timber stump failure or damp subfloors
- Subsidence on sloped or soft ground
Salt air, rain runoff, and groundwater seepage all take a toll over time. If your home shows signs of movement, it’s best to inspect before the damage worsens.
Signs Your Narrabeen Home May Be Moving
Foundation damage usually starts subtly—here’s what to watch for:
- Sloping or creaking timber floors
- Cracks appearing near corners, windows, or door frames
- Skirting boards separating from floors
- Verandah steps pulling away
- Uneven decking or sunken patios
- Rust or rot visible under the house
These signs may seem minor—but left unchecked, they could lead to costly structural repairs.

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.

FAQs for Narrabeen Homeowners
Does living near the lagoon or beach affect my foundation?
Yes—moisture-rich sandy soils are less stable, especially after heavy rain or long dry spells. This can lead to sinking piers, shifting stumps, or floor movement.
Can you fix sloping floors without major renovations?
Absolutely. In most cases, we access underneath your home to carry out the work. No need to remove flooring or vacate the property.
Is levelling covered by insurance?
It depends. We’re happy to provide detailed reports for your insurer or engineer, and advise on the process if a claim applies.
