Leaky Balcony Repairs in Sydney present their unique set of challenges. Parking and traffic can create headaches, and many balconies in Sydney are exposed to long-term UV radiation, with surface temperatures exceeding 50 degrees in summer, all while being affected by saltwater. However, these challenges are balanced out by the idyllic weather conditions that favor outdoor work. Whether you have a small balcony, a multi-residential complex with numerous balconies, or expansive rooftops, we offer comprehensive repair and waterproofing solutions to repair and prevent water leaks.

Our Expertise in Balcony Repairs:

With years of experience, we’ve become seasoned experts in repairing and preventing balcony leaks. Sydney’s climate, with its relatively steady and predictable weather for outdoor work, provides an ideal setting for our services. We understand that no two balconies are the same; however, residential balconies typically feature timber framing, while multi-residential and rooftop balconies boast concrete slab substrates. Why does this matter? The substrate material determines how the structure behaves and, in turn, the common issues that arise. This knowledge is invaluable because most leaking balconies can be effectively repaired with remedial waterproofing solutions, eliminating the need for costly and extensive tile renovations. However, if you’re looking for a completely new balcony, we are more than capable of assisting you but typically consider this as the last resort.

Efficient Quoting Process:

We value your time, which is why most quotes can be provided within the same day. With just a few questions answered and a few photos of the affected area, we can assess your needs accurately. This efficient process empowers you to compare our quotes and options with others, giving you the information you need to make an informed decision on how to proceed.

At Leaky Balcony Repair, our name says it all, and we’re committed to delivering reliable, cost-effective, and lasting solutions for your balcony repair and waterproofing needs in Sydney. Contact us today to safeguard your investment and enjoy a leak-free outdoor space.”



There are many steps that go into waterproofing but here you can see the main steps and see that nothing else is required in order to have your balcony repaired. 


As we handle a lot of strata work and investment properties, many of the balconies that we waterproof have not been properly cleaned in many years. We clean the surface using a combination of high-pressure water and acid to reveal the balcony beneath.

Balcony Preparation

Once cleaned, the balcony reveals the extent of the repairs needed to bring the surface back to good condition. This usually involves regrouting and cutting in expansion joints to allow for increased movement as the property ages.

Once the surface is returned to a good condition the Clear Waterproofing can be applied to the surface. We tend to match the existing finish of your tiles which makes it hard to determine that membrane being installed. Finishes are all slip resistant and come in Gloss, Satin and Matte.
