The six places inter-floor leaks start
Bathroom floors first, pipes second. We test rather than guess, then repair with our own crew.

Bathroom floors
Failed waterproofing under tiles, shower areas, floor traps. The usual suspect.

Pipes
Supply and waste pipes inside walls and slabs, confirmed by pressure and flow tests.

Slab & ceiling
Water through the concrete: stains, white salt deposits, dripping.

Balconies & external walls
Rain getting in through balcony floors, windows and cracks.

Common property
Risers, corridors and shared pipes. Management’s responsibility, our repair.

Party walls
Damp through the wall you share with next door.

Before you report
What owners and managers ask us most, answered the way we answer on site.
How do you find the source?+
We inspect the affected unit and the suspected one above, then run ponding, pressure, flow or dye tests as needed. The report states what we found, which test confirmed it, and how confident we are.
Do you need access to the unit upstairs?+
Usually. Most inter-floor leaks start in the bathroom floor or pipes above. Management arranges the joint inspection; if access is refused, we record it on the case and management takes it from there.
Waterproofing or pipe?+
A ponding test isolates the floor waterproofing. A pressure test isolates supply pipes. A flow test checks waste pipes and the floor trap. Together they tell us which one failed.
When can my ceiling be repaired?+
After the source is fixed and a monitoring period passes with no recurrence. Patching the ceiling first hides the evidence and usually has to be redone.
Who pays for the repair?+
Under the Strata Management Regulations 2015, whoever’s parcel or property caused the leak pays for the repair and the damage below. Your management confirms that in writing after the inspection. We inspect and repair; management decides responsibility.
How fast can you come?+
We reply within 12 hours and usually inspect within three to five days. Active dripping goes to the front of the queue. Any inspection fee is confirmed before we come.
What if it comes back?+
Tell us through your case link during the monitoring period and we re-inspect. Some sources are intermittent or concealed, so a second round of tests or opening work is sometimes needed.
Is PU injection suitable for my leak?+
PU injection seals water paths through concrete cracks and honeycombs. It suits slab and wall cracks, not failed bathroom waterproofing or a broken pipe; the inspection tells us which one you have before anything is proposed.
Will I get a written report?+
Yes. Every inspection ends with a written report with photos, the tests done, the source and the responsible area. Your management receives it too, so Form 28 can be issued on the same finding.
