A waterproofing contractor Singapore households and businesses rely on — honest advice, clean work and long-lasting results, backed around the clock by emergency waterproofing Singapore can count on, day or night.
Water damage rarely fixes itself — it spreads. Catching it early keeps the repair small. Here’s what Singapore homeowners call us about most.

Brown rings, blistering paint or active dripping from the unit above — a sign the wet area overhead is leaking.

Hollow tiles, musty smells and damp showing up in the room or unit below your bathroom.

Wind-driven rain pushing through façade cracks, leaving internal walls wet and paint flaking.

Ponding water and cracked membranes letting rain into top-floor ceilings after every storm.

Constant soil moisture and ponding tracking back into the living room beside the balcony.

Groundwater seeping through joints and cracks under hydrostatic pressure in below-ground areas.
Hydroworks is a dedicated waterproofing and water-leak-repair company serving homes and businesses across Singapore. From a single dripping ceiling to a full commercial roof, we’ve spent more than a decade fixing the root cause of leaks — not just hiding the symptoms.
Our approach is simple: diagnose honestly, recommend the least-destructive fix, use quality materials, and leave your property clean and dry. It’s why homeowners, landlords, property managers and MCSTs keep us on speed dial — day or night.

Water Heater Tank LeakageDuring Work“Our living-room ceiling had a brown stain that kept coming back after two repaints. The Hydroworks technician traced it to the toilet seal upstairs, coordinated with our neighbour and fixed the source. Six weeks on, still bone dry.”

“I was quoted for full hacking by another contractor. Hydroworks inspected first, said only the threshold and planter needed redoing, and saved me a few thousand dollars. Honest people are rare in this trade.”

Condo Owner · Marine Parade Condo
“Every monsoon our master-bedroom wall went damp. They sealed the cracks from outside and recoated the façade. First rainy season in years with a dry wall. Tidy workers, cleaned up properly.”

Yes. Our on-site assessment and written recommendation are completely free, with no obligation to proceed. We would rather earn your trust with an honest assessment than pressure you into work you do not need.
Our emergency line is staffed round the clock, including weekends and public holidays. For an active leak we aim to attend the same day to stop the water and protect your property.
Only if it is genuinely necessary. We diagnose the real source first, and where the structure is sound we use surface or injection methods that avoid full hacking. No unnecessary hacking is a promise, not a slogan.
Yes. We use low-VOC, child- and pet-friendly waterproofing materials that are safe once cured — important for family homes where bathrooms and balconies see daily use.
Every project is backed by a written workmanship warranty. The exact period depends on the system used, and we set it out clearly in your quotation before any work begins.
All of them. We work with HDB and condo owners, landed homeowners, property managers, MCSTs and commercial buildings across Singapore, scaling our approach to suit each.
It depends on the area, the cause and the method. Because we diagnose first, we can give you a fixed-scope quote rather than a vague estimate — and we explain what drives the price so there are no surprises.
Yes. Inter-floor seepage in HDB and condos is common. We document the cause clearly with photos, which helps when coordinating responsibility and access with neighbours, the MCST or Town Council.
Tell us what you’re seeing and we’ll come back fast with honest advice. For an active leak right now, call our 24/7 hotline — a real person will pick up.
