Common Strata Leak Issues

Strata buildings face unique waterproofing challenges. Here are the most common leak problems we resolve for property managers across Sydney.

Shared Bathroom Walls

Leaks between adjoining units through shared wet walls are one of the most common strata complaints. Failed shower waterproofing allows water to migrate through party walls, causing damage to neighbouring units.

Aging Balcony Membranes

Balcony waterproofing membranes in older buildings deteriorate over time, leading to water ingress and concrete degradation. Regular inspection can identify membrane failure before spalling develops.

Common Area Water Ingress

Leaks in corridors, stairwells, and car parks often stem from failed expansion joints or degraded waterproofing. These affect multiple residents and require prompt, professional attention.

Planter Box Leaks

Built-in planter boxes on balconies and podiums are a frequent source of water ingress. Constant moisture exposure and root growth accelerate membrane breakdown.

Real Strata Leak Scenarios We Handle

These are the situations strata managers bring to us most often. Every scenario below is one we've diagnosed and resolved across Sydney.

Unit Above Leaking Into Unit Below

A shower leak in one unit causes water stains, mould, or paint damage on the ceiling of the unit below. We inspect both units, identify the source, and repair with minimal disruption to both residents.

Multiple Balconies in One Complex

Several balconies in the same building showing signs of grout failure, efflorescence, or water ingress. We assess all balconies, prioritise by severity, and schedule staged repairs with volume pricing.

Common Area Corridor Water Ingress

Water tracking through corridor floors, stairwell walls, or lift lobbies from adjacent wet areas or roof waterproofing failures. We trace the source and seal the entry point.

Post-Defect Period Remediation

Builder's warranty has expired and waterproofing defects are emerging across the complex. We provide independent assessment and remediation without the original builder's involvement.

Planter Box & Podium Leaks

Built-in planter boxes on podium levels are a common source of chronic water ingress. Root damage, constant moisture, and failed membranes require specialist repair.

Pre-Sale Leak Rectification

An owner needs a leak resolved and documented before settlement. We provide fast-turnaround repairs with full compliance documentation for conveyancing requirements.
