Common answers

Waterproofing questions and answers for Pennant Hills

The most common questions from Upper North Shore property owners.

What does waterproofing cost in Pennant Hills?

Waterproofing costs in Pennant Hills depend on the area, size and whether the work is a new application or a remedial repair. Pro Leak Waterproofing provides a free, fixed-price quote after inspection, with no call-out fee, so you know the exact price before work begins.

Can I check that your waterproofers are licensed and insured?

Yes. Pro Leak Waterproofing is a licensed waterproofing contractor, licence 55 630 801 277, and our technicians are fully insured. You are dealing with qualified tradespeople who complete work to building standards.

How long does waterproofing last?

When professionally installed on a properly prepared surface, waterproofing typically lasts around 10 years or more, with external membranes often lasting longer. Choosing the right system for the area and meeting Australian Standards makes the difference.

How long does it take to waterproof a bathroom?

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 can I tell if my waterproofing has failed?

Common signs that waterproofing has failed include damp or musty smells, water marks on ceilings or walls, bubbling or peeling paint, cracked or drummy tiles, efflorescence and mould. If you see these in Pennant Hills, book an inspection early to help avoid a larger repair.

How do I know if I need remedial waterproofing?

Remedial waterproofing is the repair of existing waterproofing where the system has failed or was not installed correctly. Instead of simply treating the symptom, we find the source of the water ingress and rebuild the protection so the leak does not return.

Is your waterproofing compliant with Australian Standards?

Yes, our wet-area waterproofing meets Australian Standard AS 3740 and aligns with the National Construction Code. We use compliant membrane systems suited to each surface and application, so the finished work meets building requirements.

Can you waterproof strata and apartment buildings?

Yes. We provide strata and apartment waterproofing across the Upper North Shore, along with townhouses and duplexes. We can assist with shared balconies, common areas and individual units, while liaising with owners, managers and committees to reduce disruption.

Can existing tiles be waterproofed over?

Applying a system over existing tiles may be possible in some cases, but it depends on the condition of the substrate and where the water is entering. We always inspect and diagnose first, then recommend a repair that solves the problem properly.

How quickly can you arrange waterproofing work?

We can usually arrange inspections within 24 to 48 hours, and support is available 7 days a week from 6AM to 10PM. Work start dates are confirmed when you accept your fixed-price quote.

Why are balconies and rooftops prone to leaks?

Leaks on balconies and rooftops usually stem from ageing or cracked membranes, poor falls, drainage failure, failed grout or sealant, and blocked outlets. On leafy, sloped Upper North Shore properties, heavy rain and runoff make these problems more common.

Is your waterproofing backed by a guarantee?

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

Can I arrange a free waterproofing quote for my Pennant Hills property?

Yes, every quote we provide in Pennant Hills is free and fixed-price, with no call-out fee. Call 1300 863 001 or request a quote online to book an inspection at a time that suits you.
