Frequently asked questions

Waterproofing questions and answers for Mount Colah

The questions we hear most from Upper North Shore property owners.

How much will waterproofing cost for my Mount Colah property?

The price of waterproofing in Mount Colah depends on the area being treated, its size and whether the work is a new application or a repair. Pro Leak Waterproofing gives you a free, fixed-price quote after inspection, with no call-out fee.

Are your waterproofers properly licensed and fully insured?

Yes, Pro Leak Waterproofing is licensed as a waterproofing contractor under 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 will a waterproofing repair hold up?

Professionally installed waterproofing typically offers around 10 years or more of performance, and external membranes may last longer, when the surface is properly prepared and the correct system is applied to Australian Standards.

How long will bathroom waterproofing take?

Bathroom waterproofing typically involves one to two days of membrane work, followed by curing time before tiling. Remedial jobs vary depending on what needs to be removed and repaired, and we confirm timing in your quote.

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

Signs of failed waterproofing can include damp or musty smells, water stains on ceilings or walls, bubbling paint, peeling paint, cracked or drummy tiles, efflorescence and mould. If you notice these in Mount Colah, book an inspection early to help keep repairs smaller and cheaper.

How is remedial waterproofing different from new waterproofing?

Remedial waterproofing is for existing waterproofing that has failed or was never installed the right way. We diagnose the source of the water ingress and rebuild the protection, rather than only treating the symptom.

Can you confirm your waterproofing meets Australian Standards?

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

Can you waterproof shared areas in strata and apartment buildings?

Yes, strata buildings, apartments, townhouses and duplexes are all included in our Upper North Shore waterproofing services. We work on shared balconies, common areas and individual units, and can liaise with owners, managers and committees to minimise disruption.

Do you waterproof over existing tiles?

In some cases, an appropriate system can be applied over existing tiles, provided the substrate and source of water ingress are suitable. We inspect and diagnose first, then recommend the approach that solves the problem rather than hiding it.

How soon can my waterproofing job start?

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 do balcony and rooftop areas start leaking?

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.

Is there a warranty for your waterproofing services?

Yes. Our waterproofing work is backed by a workmanship guarantee and quality, compliant systems designed to last. The specific terms are confirmed with your quote so everything is clear in writing.

Do you provide free fixed-price waterproofing quotes in Mount Colah?

Yes, quotes in Mount Colah are free and fixed-price, with no call-out fee. Call 1300 863 001 or request a quote online, and we’ll book an inspection at a time that suits you.
