Sydney's mix of heavy downpours, coastal humidity and ageing housing stock means water finds its way into homes through walls, roofs, balconies and wet areas. Left untreated, that moisture causes structural damage, rot and mould. Professional waterproofing seals these vulnerabilities for good.
When it comes to waterproofing your home, shortcuts cost more in the long run. Our team uses high-quality membranes and proven application methods tailored to Sydney conditions, so when you waterproof your house with Sydney One you get long-lasting protection that complies with Australian Standards AS 3740 and AS 4654 on every job.
Waterproofing is one of the highest-return investments you can make in your home. Here is what professional protection delivers.
Sydney's sporadic heavy rainfall can seep through walls, roofs and foundations. Proper waterproofing stops moisture before it causes structural damage and mould growth.
A professionally waterproofed home is more attractive to buyers and inspectors, and can command a higher resale value when it comes time to sell.
Waterproofing reinforces the structure of your home, extending its lifespan and reducing the ongoing maintenance and repair costs caused by water ingress.
Sealing wet areas and external surfaces removes the moisture that mould and mildew need to grow, protecting both your home and your family's health.
Every residential job meets AS 3740 for wet areas and AS 4654 for external surfaces, keeping your home compliant and your insurance valid.
We stand behind our work with a written 10-year workmanship warranty, plus the manufacturer's warranty on the membranes and sealants we use.
From internal wet areas to external surfaces, we protect every area of your Sydney home that is exposed to water.
