Waterproofing isn’t something most homeowners think about, until it fails. Over time, exposure to Sydney’s heat, rain and movement naturally wears down membranes. Knowing when it’s time to renew your waterproofing can save you from costly leaks and repairs later.
How Long Waterproofing Really Lasts
Quality bathroom or balcony waterproofing in Sydney should last around 7–12 years, depending on the materials used, climate conditions, and how the area is maintained. External surfaces like balconies often deteriorate faster due to UV exposure and movement in the slab.
Common Signs It’s Time for Renewal
Peeling or bubbling paint on lower walls or ceilings below wet areas.
Musty odours or mould near showers or corners of balconies.
Cracked tiles or grout lines that never fully dry.
Efflorescence — white salts appearing on concrete or tile surfaces.
Soft, swollen skirting boards or timber floors near bathrooms.
These symptoms often mean moisture is bypassing the original membrane.

We inspect, remove failed layers, prepare the substrate, and apply high-performance membranes tested with the PosiTector 200 to confirm film thickness. Every project is compliant with AS 3740 and AS 4654.2, ensuring your home stays dry for the next decade.
