Balcony Waterproofing Services Provided Across Sydney
Specialised balcony waterproofing services that address the system, the details, and the proof. Whether it’s a small residential repair or a large strata project, our team ensures the right materials and detailing are in place to achieve watertight results.
Membrane Systems
Every balcony needs a system suited to its substrate, exposure, and use. We install high-performance membranes from leading manufacturers, providing long-term protection against water ingress. From torch-on and liquid-applied membranes to sheet and hybrid systems, we select products based on site conditions, compatibility, and warranty coverage.
Edge and Drain Detailing
Leaks most often begin at the edges and outlets — the critical transitions between surfaces. Our technicians carefully inspect these areas and rebuild them with proper falls, bonded flanges, and secure terminations. We reinstate balcony trims, flashings, and drainage components so water flows freely and doesn’t pool against thresholds or walls.
Testing and QA
Waterproofing success depends on testing and accountability. Before completion, every balcony is checked for adhesion, coverage, and performance. We conduct flood testing, moisture readings, and photographic documentation to confirm quality. Detailed reports are provided to strata committees and owners, ensuring transparency from start to finish.

Common Questions About Balcony Waterproofing
Balcony waterproofing can be complex, and most property owners aren’t sure where leaks start or how to fix them properly. Below, we’ve answered the most frequent questions about balcony waterproofing Sydney to help you make informed decisions about repairs, maintenance, and compliance.
Where Do You Offer Balcony Waterproofing Services?
Our team is based in Sydney’s Eastern Suburbs and provides balcony waterproofing services across the wider metropolitan area, including the CBD, Inner West, Lower North Shore, Northern Beaches, St George, and Sutherland Shire. If you’re outside these areas, we’re happy to discuss your project and arrange a site visit.
What Causes Most Balcony Leaks?
The most common causes are poor edge detailing, inadequate drainage, failed membranes, or incompatible finishes. Movement between structural elements can also open joints and seams. Regular inspections and professional remedial waterproofing prevent small leaks from becoming major structural issues.
Can You Waterproof Without Removing the Tiles?
In some cases, yes. Certain over-tile systems can be applied if the existing surface is stable and properly prepared. However, full tile removal is often recommended for lasting results, as it allows us to inspect the substrate and correct underlying issues before applying a new membrane.
How Long Will a New Balcony Membrane Last?
When installed correctly and maintained, a high-quality balcony membrane should last 10 to 15 years or longer. Factors such as drainage, UV exposure, and traffic load all affect longevity. We select materials suited to each environment and provide maintenance guidance to maximise service life.
Do You Provide Flood Testing and Reports for Strata or Insurers?
Yes. All waterproofing works include testing and quality assurance documentation. We conduct flood testing and issue detailed reports with photographs for strata records, insurance claims, or warranty documentation. Every project is verified before handover to confirm full performance.
Do you handle waterproofing for bathroom renovations?
Balconies can usually be returned to service within two to three days, depending on curing conditions and the membrane type. We provide a clear timeline before starting work and confirm when it’s safe to reinstall tiles, railings, or furniture.
