Helpful waterproofing answers

Helpful waterproofing FAQs for Cheltenham

What Upper North Shore property owners ask us most often.

How much should I expect to pay for waterproofing in Cheltenham?

Waterproofing cost in Cheltenham depends on the job area, its size and whether it is new waterproofing or a remedial repair. Pro Leak Waterproofing gives you a free fixed-price quote after inspecting the job, with no call-out fee.

Are all your waterproofers 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 a waterproofing membrane 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.

What is the usual timeframe for bathroom waterproofing?

Most bathroom waterproofing applications are completed over one to two days for the membrane work, with curing time required before tiling. Remedial jobs depend on what needs to be removed and repaired, and we confirm the timeframe in your quote.

How do I know if water is getting past the waterproofing?

You may have failed waterproofing if there are damp or musty smells, stains on ceilings or walls, bubbling or peeling paint, cracked or drummy tiles, efflorescence or mould. If you notice these signs in Cheltenham, an early inspection can help keep repairs smaller and cheaper.

When do you need remedial waterproofing?

Remedial waterproofing repairs existing waterproofing that has failed or was not installed correctly in the first place. Rather than just treating the symptom, we diagnose the source of the water ingress and rebuild the protection so the leak does not return.

Is your wet-area waterproofing compliant with Australian Standards?

Yes. Our wet-area waterproofing is completed to AS 3740 and aligns with the National Construction Code, using compliant membrane systems suited to each surface and use so the finished work meets building requirements.

Do you waterproof strata and apartment buildings?

Yes, we handle waterproofing for strata, apartments, townhouses and duplexes across the Upper North Shore, including shared balconies, common areas and individual units. We can coordinate with owners, managers and committees to keep disruption minimal.

Can you apply waterproofing over tiles?

Waterproofing over existing tiles can be an option in some cases, but it depends on the surface condition and the source of the water ingress. We always inspect and diagnose first, then recommend the solution that will actually resolve the problem.

How soon can waterproofing repairs be started?

Inspections can usually be organised within 24 to 48 hours, and our team offers support 7 days a week from 6AM to 10PM. The work start date is confirmed after quote acceptance.

What causes rooftop and balcony water ingress?

Balcony and rooftop leaks usually occur when membranes crack or age, drainage is poor, falls are incorrect, grout or sealant fails, or outlets become blocked. On leafy, sloped Upper North Shore blocks, heavy rain and runoff can quickly expose these weaknesses.

What warranty do you offer on waterproofing?

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

Are your waterproofing quotes in Cheltenham free of charge?

Yes, every quote we provide in Cheltenham 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.
