WaterproofingGuy.sg

WaterproofingGuy.sg is Singapore’s trusted specialist for professional waterproofing and leakage repair services across residential and commercial properties. We help homeowners, landlords, and property managers prevent costly structural damage caused by water ingress, humidity, and poor surface protection.

In Singapore’s humid, rain-intensive climate, untreated leaks can compromise ceiling stability, encourage mould growth, and degrade property value. That’s why our team delivers precise, solution-based waterproofing — not just patchwork repairs.

We provide a full range of services including:

Balcony leakage repair to stop seepage from ponding water and hairline cracks

Car porch ceiling and joint sealing to prevent visible leaks and internal deterioration

Kitchen waterproofing for backsplash walls, subfloors, and water pipe intersections

Toilet leak repair using non-hacking methods and PU injection for waterproofing membranes

Roof, external wall, ceiling and pipe sealing using polymer-based or cementitious coatings

High-pressure washing for roof tiles, exterior walls, and concrete surfaces

Swimming pool waterproofing with chemical-resistant membranes and regrouting

Each project begins with a detailed surface inspection and leakage assessment. We use branded sealants, membrane systems, and pressure-based treatments tailored to your surface material — from ceramic to concrete, wood to composite panels.

✅ IR camera moisture detection

✅ PU and epoxy injection for cracks

✅ Membrane torching or brush-on systems

Our waterproofing approach adheres to local building codes and is designed to extend the service life of roofs, balconies, toilets, and high-traffic areas. We serve both landed and high-rise units across Singapore, with tailored solutions for private homes, HDB flats, and commercial buildings.
