Service Overview

Proper balcony waterproofing is essential for the longevity of any Sydney property, especially those exposed to harsh coastal weather and high UV levels. A failed membrane can allow water to seep into the structural floor, leading to expensive building damage and concrete spalling. We specialise in the full installation and repair of advanced waterproofing systems for all outdoor tiled areas. Our licensed professionals understand Sydney’s building codes and use industrial-grade polyurethane membranes that are designed to remain flexible under extreme thermal movement. With over 25 years of experience, we provide an upfront quote and a lifetime workmanship guarantee, ensuring your balcony remains watertight for decades to come.

What You Get

Our balcony waterproofing service is a complete technical solution for building safety. We don’t just paint on a membrane; we design a layered system that manages water flow and structural movement. The service includes total surface preparation, the installation of high-bond primers, and multiple layers of UV-resistant liquid membrane. We pay special attention to the ‘critical zones’ like corners, junctions, and waste flanges where most failures occur. You receive a full waterproofing compliance certificate and our lifetime workmanship guarantee. We offer a $0 callout fee for all site assessments made before 4pm today.

What We Handle

We provide balcony waterproofing for all types of residential and strata structures across Sydney. Our scope covers new luxury builds, high-rise apartment terraces, and heritage refurbishments. We are experienced in working with concrete slabs, timber-framed balconies, and composite structures. Whether you are building a new entertaining deck or replacing a 20-year-old failed system, our licensed team has the technical credible skills to deliver a compliant fix. We serve everything from the Northern Beaches to the Western Suburbs, ensuring every project meets the strict AS 4654.2 standards for external waterproofing.

How We Get It Done

We begin by mechanically grinding the surface to ensure it is clean and porous for maximum membrane adhesion. After providing an upfront quote, we install ‘bond breakers’ at all wall-to-floor junctions to allow for natural building movement. We then apply a high-bond primer followed by two or more coats of our specialised liquid membrane, ensuring a seamless barrier. We pay particular attention to the waste outlets, handrail post penetrations, and door sills. Once cured, we perform a 24-hour flood test to verify the system is 100% watertight. We finish by providing you with a compliance certificate. Save $65 by booking online today. Our family-owned team delivers reliability you can trust.

A failed membrane is the leading cause of building disputes and expensive remedial work in Sydney today. By using our licensed team, you ensure the job is done once and done correctly.

Answers to Your Common Questions

A professionally installed polyurethane membrane in Sydney typically lasts between 15 to 20 years before requiring a refresh today.

In some cases, yes, using clear penetrating waterproofers. However, for a 100% guarantee, removing the tiles and applying a new membrane is best today.

Yes. All new waterproofing work must be accompanied by a compliance certificate to meet NSW building regulations and insurance requirements.

A standard balcony waterproofing project takes between 2 to 4 days, depending on the required drying times between coats.

It is much cheaper than fixing structural concrete cancer later. We provide an upfront fixed quote so you know the investment before we start.

A failed waterproofing membrane is a serious building defect that can lead to rapid structural decay and concrete cancer. Whether it’s a small tear in a bathroom corner or widespread failure on a large balcony, you need a technically credible fix fast. We specialise in the professional repair of all types of waterproofing membranes across Sydney, using advanced liquid and sheet technologies to restore your building’s barrier. Our licensed team understands how Sydney’s thermal cycles and ground movement can stress membranes to the point of failure. With over 25 years of experience, we provide an upfront quote and a lifetime workmanship guarantee, ensuring your wet areas are made safe and compliant today.

Old, mouldy, or peeling silicone is more than just an eyesore; it is a critical weak point where water can seep behind your tiles and rot your home’s frame. Over time, standard silicone shrinks and pulls away from joints, especially in Sydney’s high-humidity wet areas and sun-drenched balconies. We provide professional silicone replacement services that ensure a 100% watertight and antimicrobial seal for your home. With over 25 years of experience, we use only high-grade sanitary and UV-resistant sealants that are designed to last. We provide an upfront quote before we start and a lifetime workmanship guarantee, giving you a technically credible fix that restores both the look and safety of your bathroom and balcony today.

Old, cracked, or porous grout is the leading cause of water ingress behind shower tiles, leading to timber rot and mould. Our professional shower regrouting service restores your shower’s waterproof barrier while giving your bathroom a fresh, clean appearance. We don’t just apply a ‘skin’ of grout over the old stuff; we manually remove the degraded material to ensure a deep and lasting bond. We understand Sydney’s building standards and use high-grade polymer-modified or epoxy grouts that are resistant to cracking and staining. With over 25 years of experience, we provide an upfront quote and a lifetime workmanship guarantee, making your shower look and function like new today.

A leaking shower can quietly destroy your home’s subflooring and structural timber without you ever seeing a puddle. By the time damp spots appear on the hallway carpet or the ceiling below, the damage is often extensive and expensive to fix. We specialise in non-invasive shower leak repairs that fix the issue without necessarily removing every tile. Our team understands how Sydney’s climate and common building methods can lead to membrane failure or grout degradation over time. We offer a 60-minute response to assess the leak and provide an upfront quote, using advanced silicone and sealing technologies to restore your bathroom’s integrity today.

A hidden water leak behind a wall or under a floor can cause thousands in structural damage before you ever see a puddle. If your water bill has spiked or you see damp spots on your ceiling, you need a precision diagnostic fast. We utilise advanced acoustic sensors and thermal imaging technology to find hidden leaks without having to break your walls apart. We understand Sydney’s high-pressure council mains that can stress internal pipework to the point of failure. With over 25 years of experience, we provide a 60-minute emergency response to find the leak and offer an upfront quote for the fix. Our family-owned team ensures your home is protected today.

An underground water main leak can waste thousands of litres of water every day, leading to high water bills and ground subsidence around your property. Because these leaks are buried deep under lawns, driveways, or gardens, they often go unnoticed for months. We provide specialised external leak detection services across Sydney, utilizing high-powered acoustic microphones and tracer gas to find hidden failures without digging up your yard. We understand how Sydney’s varied soil conditions — from coastal sand to western clay — can stress underground pipes. With over 25 years of experience, we provide a 60-minute emergency response to find the leak and offer an upfront quote for the fix today.
