Bathroom leaks we fix
Leaking to the unit below
Water stains or drips on the downstairs ceiling almost always trace back to a failed bathroom waterproofing layer or floor trap. We pinpoint the source and stop it.
Shower and wet-area floors
Constant water exposure breaks down old membranes and grout. We re-waterproof the floor, kerbs and the corners where the floor meets the wall.
Tiled wall seepage
Moisture travels behind tiles through cracked grout and pipe penetrations. We seal these entry points before the damage spreads.
Cracked grout and silicone joints
Aged, mouldy grout and perished silicone let water past the surface. We renew these joints as part of a lasting fix.
Bathroom waterproofing methods
We match the method to your situation, from a minor seepage to a full re-do.
Leak source tracing
We inspect the bathroom and the ceiling below to confirm exactly where water is getting through before any work begins.
PU injection (non-hacking)
Polyurethane injected into the slab and cracks to stop active leaks without hacking up your floor tiles.
Hacking and re-membrane
For failed waterproofing, we hack the affected area, lay a fresh membrane and reinstate the screed and tiles.
Joint and grout renewal
Re-grouting and re-sealing kerbs, corners and pipe penetrations so the repair holds up to daily use.

How we work
One clear process, start to warranty
The same disciplined method on every job, so you always know what happens next and why.
- 01
Diagnose
A free, no-obligation site inspection. We trace the water path to its true source, not just where the stain shows, using moisture mapping and, where needed, rope-access close-up survey.
- 02
Recommend
A clear written recommendation matched to your building, budget and timeline: the method, why it suits Singapore’s climate, what it costs, and how long it lasts.
- 03
Execute
Our trained crews carry out the works with minimal disruption, surface preparation, treatment and protective coating done to specification, with safety and tidiness on site.
- 04
Document
You receive a photographic record of the works and, for façade inspections, a full condition report, the documentation facility managers need for BCA and building records.
- 05
Warranty
Every completed project is backed by a Certificate of Warranty, from 1 to 10 years depending on the system, so the result is protected long after we leave.
Common questions
Straight answers to what homeowners and building managers ask us most.
Not always. If the leak is from cracks or pipe joints, PU injection can stop it without hacking your tiles. If the waterproofing membrane itself has failed, hacking and re-membraning is the proper long-term fix. Our free inspection tells you which one your bathroom needs, with photos, so you can decide with full information.
