Commercial & Strata Waterproofing & Leak Repairs in Sydney
One leaking shower in a strata building is never one unit's problem. Water travels to the apartment below, and suddenly a small repair is an insurance claim. SmartSealed provides leak detection, sealing and waterproofing to strata schemes, facility managers, commercial properties and hotels across Greater Sydney, fixing leaks at the source with minimal disruption to residents and tenants.

Why managed properties choose SmartSealed
No demolition in occupied units. Most shower and balcony leaks are sealed over existing tiles: residents lose access for hours, not weeks, and the area is back in use 24 hours after completion.
Documented findings. Our leak detection service delivers a written report with photos and a scope of works: exactly what a committee or building manager needs to approve works.
One contractor across the building. Showers, balconies, common-area wet zones, grouting and tiling, membrane replacement, all handled by the same licensed technicians.
Clean working practices. No fuss, no mess, punctual and reliable, with 30+ years working in occupied buildings.
Upfront, transparent pricing. Clear quotes per unit or per scope, no hidden fees.

Builders & trade
Handing over a bathroom or balcony with a leak puts your reputation on the line. SmartSealed works alongside builders and trades across Sydney to identify the true source of a leak, whether poor grouting, loosely-adhered tiles, tapware faults, membrane problems or building movement, and seal it before handover or after a defect claim. Fast turnaround: most jobs completed in a few hours, safe to use after 24.

Common questions
Before you ask.
Can repairs be done while units are occupied?
Yes. That's the core of our approach. Sealing over existing tiles means no demolition, no noisy machinery, and the bathroom or balcony is back in use 24 hours after we finish.
Do you provide reports for strata committees?
Yes. Leak detection includes a written report with photos and a scope of works, priced separately from any repair, so the committee can make its decision with the facts in front of it.
Can you handle multiple units in one visit?
Yes. We regularly schedule building-wide programmes with the manager so residents get notice and works are grouped efficiently.
Who do you work with?
Strata and community schemes, building and facility managers, commercial property owners, hotels, real estate agencies and builders. For tenanted residential properties managed by agents, see Real Estate.
