Expert Balcony Renovations Sydney

A complete balcony renovation typically includes removal of existing tiles, structural assessment and repair of the substrate, full waterproofing membrane installation, drainage correction or installation, and premium tile installation with weather-resistant grouting. Depending on your balcony's condition, it may also include concrete cancer treatment, railing repairs, and threshold modifications. We manage the entire process from assessment to handover.

Balcony renovation costs in Sydney typically range from $5,000 for a small balcony refresh to $25,000+ for a large balcony requiring extensive structural repairs. Key factors affecting cost include balcony size, extent of structural damage, waterproofing complexity, tile selection, and access requirements (high-rise apartments may incur additional charges). We provide detailed, transparent quotes based on a thorough site assessment so you know exactly what to expect. Read our complete tiling cost guide for more pricing information.

A typical balcony renovation takes 7-14 working days depending on the scope and complexity. This includes 1-2 days for tile removal and assessment, 1-3 days for structural repairs (if needed), 1-2 days for waterproofing application and curing, 2-3 days for tile installation, and 1 day for grouting and finishing. Weather conditions can impact the timeline, particularly for waterproofing which requires dry conditions. We provide a detailed schedule specific to your project.

For apartments and strata properties, you will almost always need written approval from the owners corporation or strata committee before starting balcony renovation work. This is because balcony waterproofing typically affects common property, and the renovation may impact the building's external appearance. We can assist with the approval process, provide documentation for your strata manager, and ensure all work complies with strata by-laws and building codes.

Balcony leaks are most commonly caused by failed or deteriorated waterproofing membranes, cracked or missing grout allowing water penetration, inadequate drainage falls causing water pooling, or structural cracks in the concrete substrate. Yes, these issues can be fixed, but typically require a complete renovation approach rather than a patch repair. Our thorough assessment identifies all contributing factors so we can implement a complete solution that addresses the root cause.

For Sydney balcony renovations, we recommend porcelain tiles due to their extremely low water absorption (<0.5%), UV stability, frost resistance, and availability in slip-resistant finishes (R11 or higher). Large format porcelain tiles create a modern look and have fewer grout lines to maintain. Natural stone like granite is also suitable when properly sealed. We advise against standard ceramic tiles and unsealed natural stones like marble or limestone for exposed balconies.

A professionally executed balcony renovation with quality waterproofing and appropriate materials should last 15-20+ years in Sydney's climate. The waterproofing membrane typically carries a 10-15 year warranty, while porcelain tiles can last 20+ years with minimal deterioration. Regular maintenance, including keeping drains clear, periodic cleaning, and proactive inspection every 2-3 years, significantly extends the life of your renovation.

While overlay systems exist, we generally recommend full tile removal for balcony renovations. This allows us to properly inspect the substrate for structural issues, remove and replace failing waterproofing, correct drainage falls, and ensure the new tiling system performs correctly long-term. Overlaying existing tiles risks trapping moisture, doesn't address underlying waterproofing failures, and can create height issues at doorways. We assess each situation individually and recommend the best approach for your specific balcony. See our tile over or tear out guide for the full pros and cons.
