Waterproofing Services We Provide
Most leaks in Singapore homes come from a handful of places. We match the repair method to the source of the water, not just the stain you can see.
| Service | Common problem | Typical fix |
|---|---|---|
| Roof waterproofing | Flat RC roof leaks, ponding water, cracked screed | PU / liquid membrane, torch-on membrane, crack repair |
| Roof repair | Broken tiles, failed flashing, metal roof screw-hole leaks | Tile and flashing repair, sealant and coating |
| Balcony waterproofing | Water seeping into the ceiling below after rain | Membrane re-application, joint sealing, drainage correction |
| Toilet waterproofing | Leaks into the ceiling of the floor below | Hacking and new membrane, or non-hacking sealing for minor cases |
| Wall leakage repair | Bubbling paint, damp patches, external wall cracks | Crack sealing, PU injection, external wall coating |
| Ceiling leak repair | Stains spreading after heavy rain | Leak tracing to the true source, then targeted repair |
How Our Waterproofing Service Works
- Free leak inspection. We check the roof, wet areas and drainage, and use thermal-imaging leak tracing where the source is hidden.
- Written, itemised quotation. You get the recommended method, scope, timeline and warranty in writing before any work starts.
- Surface preparation. Cracks are repaired, loose material removed and the surface primed so the new system bonds properly.
- Waterproofing application. The chosen membrane or coating is applied in the correct number of layers, with safe access and MOM-certified scaffolding for two-storey roofs.
- Final check and handover. We inspect the finished work, explain simple maintenance, and issue your warranty.
Why Homeowners Choose NexTech Waterproofing
- Landed-home focus: inter-terrace, corner terrace, semi-detached and bungalow roofs, balconies and wet areas.
- Source first, then repair: we trace where water actually enters, so you do not pay to redo areas that never needed it.
- Clear pricing: from S$900 for smaller landed-home jobs; larger roofs and whole-house work are quoted after the free inspection.
- Written warranty: 1 to 5 years depending on roof condition, confirmed before work begins.
- Proven track record: 500+ jobs completed and a 5.0-star Google rating.

Waterproofing Contractor Singapore: FAQs
How much does waterproofing cost in Singapore?
For landed homes, NexTech Waterproofing jobs start from S$900. The final price depends on the size of the area, its condition, access, and the waterproofing system used. Larger roofs are quoted after a free site inspection.
How do I choose a waterproofing contractor in Singapore?
Choose a contractor that inspects before quoting, explains the cause of the leak, gives an itemised written quotation, and states the warranty period in writing. Check recent Google reviews and ask what system will be used and how many layers.
What warranty do you give?
We give a written warranty of 1 to 5 years, depending on the condition of the roof or surface. The warranty period is confirmed in your quotation before work starts.
How long does a waterproofing job take?
Most residential jobs such as a toilet, balcony or wall leak take about 1 to 3 days, depending on the area and drying time. Larger roof or landed-house projects take longer and the timeline is given in the quotation.
Is the leak inspection really free?
Yes. The site inspection is free and there is no obligation to proceed. You receive our findings and a written quotation afterwards.
