Common waterproofing problems

Recognise any of these warning signs?

Water damage rarely fixes itself — it spreads. Catching it early keeps the repair small. Here’s what Singapore homeowners call us about most.

Water-stained ceiling with spreading brown stains and peeling paint

Ceiling Stains & Drips

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

Water seeping down bathroom wall tiles

Bathroom & Toilet Seepage

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

Interior wall with bubbling, cracked and peeling paint from damp

Damp & Peeling Walls

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

Rainwater overflowing off a roof onto a ponding flat surface

Roof & Top-Floor Leaks

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

Rooftop balcony floor with ponding water beside a planter

Balcony & Planter Leaks

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

Flooded basement car park with standing water across the floor

Basement & Car Park Water

Groundwater seeping through joints and cracks under hydrostatic pressure in below-ground areas.

Rated 5.0 by the people we’ve kept dry

Read us on Google
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.

Wei Lin Tan

HDB Owner · Bishan HDB

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.

Priya Nair

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.

FAQ

Answers before you ask

Is the free assessment really free, with no obligation?

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.

Do you really operate 24 hours, 7 days a week?

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.

Will you hack up my whole floor?

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.

Are your materials safe for children and pets?

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.

Do you provide a warranty?

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.

Do you handle HDB, condo, landed and commercial properties?

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.

How much does waterproofing cost?

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.

Can you help with an inter-floor leak involving my neighbour?

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.
