Licensed waterproofing services across Hornsby
Properties across Hornsby and the Upper North Shore are often positioned on leafy, shaded and sloping streets, with a mix of older brick homes, family houses, duplexes, townhouses, apartments and strata buildings. Heavy rain, stormwater runoff, blocked gutters, poor drainage and ageing membranes can lead to concealed leaks, damp walls, mould, ceiling stains, peeling paint and cracked tiles.
Pro Leak Waterproofing focuses on finding the real cause of water ingress in Hornsby and applying the correct repair, rather than sealing over the symptom. With 10+ years of waterproofing experience, licensed technicians and transparent fixed pricing, we protect bathrooms, balconies, rooftops, laundries, external walls and retaining-wall moisture issues before damage spreads.
Every job begins with a detailed inspection, so you know exactly what is failing and why. You receive a clear fixed-price quote and workmanship you can trust, supported by compliant systems and a tidy, professional finish.

Hornsby waterproofing FAQ
Common waterproofing questions from Upper North Shore property owners.
What should I budget for waterproofing in Hornsby?
Are your waterproofers qualified, licensed and insured?

How much time does bathroom waterproofing usually take?
How do I know if my wet-area waterproofing has failed?
What does remedial waterproofing include?
Remedial waterproofing is used to repair waterproofing that has failed or was never installed properly. Instead of only treating the symptom, we diagnose the source of the water ingress and restore the protection so the leak does not come back.
Can you confirm your waterproofing meets Australian Standards?
Yes, our wet-area waterproofing is completed in accordance with Australian Standard AS 3740 and the National Construction Code. We select compliant membrane systems for each surface and use, so the finished work meets building requirements.
