Expert waterproofing for bathrooms, balconies, roofs, basements and more. Fully licensed, insured, and trusted by hundreds of Sydney homeowners and businesses.
From internal wet areas to external structures, we cover every waterproofing need for residential and commercial properties throughout Sydney.
Leaking showers and bathrooms are the #1 cause of water damage in Australian homes. We waterproof all internal wet areas using premium membranes — done right the first time, every time.
Sydney's harsh sun and heavy rain put constant pressure on your balconies, decks and external structures. We apply durable membrane systems that protect your property from the outside in.
A failing roof membrane can cause catastrophic water damage throughout your entire building. We install and repair commercial-grade roof membrane systems for residential and high-rise properties across Sydney.
Below-ground structures face relentless hydrostatic pressure. Our basement waterproofing specialists stop water ingress at the source — using both positive and negative-side solutions including injection systems for active leaks.
Pool leaks waste thousands of litres of water and silently damage the surrounding structure. We waterproof new pools, repair existing leaks and seal water features using systems designed for permanent immersion.
Can't find where the water is coming from? Our specialist team uses advanced thermal imaging, moisture meters and flood testing to pinpoint the exact source — fast and accurately, without unnecessary damage.
We're not just waterproofers — we're your neighbours. Water Proofing Bros has been protecting Sydney homes and businesses for over 15 years, and we stand behind every job we do.
All work is carried out by licensed waterproofing contractors. We carry full public liability insurance for your peace of mind.
Every job comes with a written workmanship guarantee. If it leaks after we've waterproofed it, we come back and fix it — no questions asked.
