Why Choose NexTech Waterproofing?
A balcony is a flat, exposed slab that takes direct rain, so small defects show up quickly as stains on the ceiling below or damp skirting inside the house. The usual causes:
| Cause | What you notice | Typical repair |
|---|---|---|
| Failed or aged membrane under the tiles | Ceiling stain below that grows after every rain | Hack tiles, new membrane, re-tile |
| Cracked grout or hollow tiles | Water disappears into joints, tiles sound hollow | Re-grout and seal, or non-hacking coating |
| Wall-floor junction gaps | Damp patches at the inside skirting | Joint sealing and upturn waterproofing |
| Poor falls or blocked floor trap | Water ponds for hours after rain | Clear or reposition outlet, correct the screed fall |
| Hairline cracks in the slab | Drips or efflorescence on the ceiling below | PU injection into the crack |
Not every balcony leak needs the tiles removed. After the inspection, we recommend the least disruptive method that will actually stop the water:
Balcony jobs start from S$900. The price depends on the balcony size, whether hacking is needed, the condition of the slab and the system used. Most balcony repairs take 1 to 3 days.
