Service Overview

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.

What You Get

Our membrane repair service is a surgical technical solution designed to stop leaks without a total rebuild. We focus on identifying the exact failure point through non-invasive diagnostics. The service includes the removal of loose tiles or debris to expose the membrane, the application of high-bond primers, and the bonding of new polyurethane or liquid membranes to the existing host material. We pay special attention to ensuring the new and old layers are seamlessly integrated. You receive a compliance report and our lifetime workmanship guarantee on all labor. We offer a $0 callout fee for all bookings before 4pm today.

What We Handle

We provide membrane repairs for all residential and commercial property types throughout the Sydney basin. Our scope covers failed waterproofing in bathrooms, laundries, balconies, and flat roof systems. We are experts at repairing both liquid-applied and bitumous sheet membranes in high-rise apartments and individual suburban homes. Whether you are dealing with a failed bond-breaker in a master ensuite or a UV-damaged membrane on a rooftop terrace, our licensed team has the technical credible expertise to deliver a permanent fix. We serve everything from the Inner West to the Northern Beaches, ensuring every repair meets AS 4654.1 standards today.

How We Get It Done

We begin by conducting a thermal moisture audit to map the extent of the failure behind the surface. After providing an upfront quote, we carefully remove the top layers to access the damaged membrane. We clean and prep the area to ensure absolute adhesion for the new material. We apply a specialised high-bond primer followed by multiple layers of our liquid polyurethane membrane, overlapping the existing material to create a continuous watertight skin. Once cured, we perform a 24-hour flood test to verify the fix. Finally, we provide you with a written report and our lifetime guarantee. Save $65 by booking online today. Our family-owned team ensures a premium fix.

Why It Matters for Your Home

The value of professional membrane repair is the prevention of massive restoration costs caused by structural rot. A small repair today can save you from a full bathroom or balcony replacement tomorrow, which can cost tens of thousands. As a family-owned Sydney business for 25+ years, we focus on providing honest advice and a fix that is technically credible. Our upfront pricing ensures transparency, and our lifetime workmanship guarantee gives you long-term security for your asset. We’ve helped over 10,000 homes stay watertight, delivering reliability you can count on with a 4.9-star reputation. Our $0 callout fee makes it affordable 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.

Failed bathroom waterproofing is a silent disaster that can lead to rotting floor joists, termite infestations, and collapsed ceilings. In Sydney, moisture-related building failures are all too common due to poor installation and building movement. We specialise in professional bathroom waterproofing for both new builds and remedial repairs across all metro areas. Our licensed experts use the highest-grade liquid membranes and bond-breaking technologies to ensure your wet areas stay 100% watertight. With over 25 years of experience, we provide an upfront quote and a lifetime workmanship guarantee, ensuring your bathroom meets all current AS 3740 standards. Don’t risk your home’s structure; let our family-owned team provide a technically credible finish today.
