What you need to know

Hornsby waterproofing FAQ

Common waterproofing questions from Upper North Shore property owners.

What should I budget for waterproofing in Hornsby?

Waterproofing costs in Hornsby can vary based on the area, its size and whether the job involves new waterproofing or remedial repairs. Pro Leak Waterproofing provides a free, fixed-price quote after inspecting the work, with no call-out fee.

Are your waterproofers qualified, licensed and insured?

Yes, you are dealing with qualified tradespeople. Pro Leak Waterproofing is a licensed waterproofing contractor, licence 55 630 801 277, and our technicians are fully insured.

What is the lifespan of waterproofing?

When waterproofing is professionally installed and applied to a properly prepared surface, it typically lasts around 10 years or more. External membranes often last longer, especially when the right system is used and Australian Standards are met.

How much time does bathroom waterproofing usually take?

Bathroom waterproofing usually takes one to two days for the membrane application, plus curing time before tiling can begin. Remedial work varies depending on what needs removal and repair, and we confirm the timeframe in your quote.

How do I know if my wet-area waterproofing has failed?

Failed waterproofing may show through damp or musty smells, water stains, peeling or bubbling paint, cracked or drummy tiles, efflorescence and mould. If you notice these issues in Hornsby, booking an inspection early can often mean a smaller, cheaper repair.

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.

Are strata and apartment buildings included in your waterproofing services?

Yes. We waterproof strata properties, apartments, townhouses and duplexes across the Upper North Shore, including common areas, shared balconies and individual units. We can coordinate with owners, managers and committees to arrange work with minimal disruption.

Can you repair waterproofing without removing existing tiles?

In some cases, existing tiles can be waterproofed over with the right system, but the substrate condition and source of the leak must be assessed first. We inspect, diagnose and recommend the approach that solves the issue rather than hides it.

How soon can waterproofing repairs be started?

Inspections are usually booked within 24 to 48 hours, and we provide support 7 days a week from 6AM to 10PM. Start dates for the work are confirmed when you accept your fixed-price quote.

What causes leaks in balconies and rooftops?

Leaks through balconies and rooftops are often caused by ageing or cracked membranes, poor falls and drainage, failed sealant or grout, and blocked outlets. On leafy, sloped Upper North Shore blocks, heavy rain and runoff can make these failures appear sooner.

Is your waterproofing backed by a guarantee?

Yes, a workmanship guarantee backs our waterproofing work, along with quality, compliant systems designed for long-term performance. The specific terms are confirmed with your quote so everything is clear in writing.

Do you provide free waterproofing quotes in Hornsby?

Yes. Every quote in Hornsby is free and fixed-price, with no call-out fee. Call 1300 863 001 or request a quote online, and we’ll arrange an inspection at a time that suits you.
