Balcony Leak Detection Brisbane
Stain on the ceiling under a balcony, bubbling paint, rusting balustrade posts, or water coming in at the door sill every time it rains? 1300 FINDLEAK finds balcony leaks across Brisbane, Ipswich, Logan and the Redlands with moisture mapping, thermal imaging, UV dye and controlled flood testing, so you know whether it's the membrane, the falls, the door sill, a balustrade fixing or a pipe, before any tiles come up. From $398 inc. GST for the first hour, with an insurance-ready report with every job.
Balcony leaking into the room or unit below?
- Keep water off the balcony: clear the drains and outlets, and don't hose or mop it until it's tested.
- Move furniture and valuables away from the wet ceiling or wall, and switch off power to any light fitting that is wet.
- Take photos for your insurer or body corporate manager, then call us on 1300 346 353.
Why balcony leaks are hard to pin down
A balcony can leak through a failed or poorly lapped waterproofing membrane, flat or back-falling tiles that hold water, a blocked or poorly sealed outlet, an unsealed door sill, balustrade post fixings drilled through the membrane, or a pipe in the slab. Water travels under tiles and along the slab, so the stain below is often metres from the cause, and re-grouting or sealing the tiles on a guess rarely fixes it.
In Brisbane we see balcony leaks in apartment blocks, where water gets into the unit or car park below and the body corporate needs to know what failed, and in homes where a balcony or deck sits over a living area. Heavy summer storms test a balcony's falls and outlets hard, so a leak may only show after a downpour. We test each part separately and show you exactly what has failed.

Membrane and tile failures
A broken, short or poorly lapped membrane under the tiles lets water into the slab and the room below. Moisture mapping and flood testing show where it gets through.
Door sills and thresholds
Water tracks under sliding door sills that sit too low or were never sealed into the membrane. We test the sill on its own to prove or rule it out.
Outlets, drains and falls
Blocked or poorly sealed outlets and tiles that fall back towards the building hold water against the membrane. UV dye shows where it escapes.
Balustrades and fixings
Post fixings drilled through the membrane and corroding over time let water into the slab edge. Thermal imaging maps the damp around each post.
Apartment and body corporate balconies
Leaks into the unit below or the car park. We test each balcony, roof and pipe source and report exactly which part failed.
Damage and mould
Long-running balcony leaks rot framing, stain ceilings and grow mould. Our report records the damage with photos and readings for your insurer.

Balcony leaks, body corporates and insurance
In apartment buildings, who is responsible for a balcony leak can depend on the plan type and on which part failed: the membrane, the tiles, the door sill or something an owner added. The body corporate needs evidence of exactly what failed before deciding who pays, and our report shows the failed part, the damage and the readings, so the right person fixes the right thing.
Insurers and loss adjusters use the same report. Whether a claim is accepted is up to your insurer.
Body corporates, property managers and homeowners
We work for body corporate managers, building managers, landlords, property managers, homeowners, builders, waterproofers and insurance loss adjusters across Brisbane, Ipswich, Logan and the Redlands. For apartments, we can arrange access to the balcony above and the unit below with the building or body corporate manager.

Balcony leak detection Brisbane FAQs
How much does balcony leak detection cost in Brisbane?
Balcony leak detection in Brisbane starts from $398 inc. GST for the first hour on site, including moisture mapping, thermal imaging, UV dye and flood testing, and an insurance-ready report. Extra time, if needed, is $168 per hour, and we'll tell you before going past the first hour.
How do I know if my balcony is leaking?
Common signs are a stain or bubbling paint on the ceiling below, water inside at the door sill after rain, drummy or lifting tiles, white staining on the grout, rust around balustrade posts and a musty smell in the room below.
Will resealing or regrouting the tiles fix a leaking balcony?
Usually not. Sealers can slow water down for a while, but if the membrane, the door sill, the outlet or a balustrade fixing has failed, water still gets through. Testing first tells you what actually needs fixing.
My balcony is leaking into the unit below. Who is responsible?
It depends on what has failed and how your building's plan treats the balcony. The membrane, tiles, sills and owner additions can fall to different parties, so our report shows exactly which part leaked to help the body corporate manager decide.
Will the report help with an insurance claim?
Our report shows which part of the balcony leaked, with photos and test results, which is what insurers and loss adjusters usually ask for. Whether a claim is accepted is up to your insurer.
Do you repair the balcony as well?
Yes, if you'd like us to. Our first visit is about finding the leak: we mark it, explain the cause and give you a report. Many waterproofers, builders and property managers then do their own repairs. If you want us to fix it, we'll quote the repair and return at another time to complete it, often with trusted independent trades.
