Landed house waterproofing in Singapore protects the parts of a terrace, semi-detached or bungalow home that take direct rain: the flat RC roof, balconies, external and parapet walls, planter boxes and the car porch slab. NexTech Waterproofing traces the real leak source first, starts from S$900, and gives a 1–5 year written warranty depending on roof condition.
At NexTech Waterproofing, we provide reliable, professional waterproofing services built for landed homes in Singapore — terrace houses, semi-detached, corner terrace, and bungalow properties. Because a landed property is entirely your own responsibility, we focus on the areas that cause the most trouble: roofs, external walls, driveways, and planter boxes. From identifying the true source of a leak to applying a durable, warrantied waterproofing system, our team keeps your home protected through Singapore’s monsoon seasons.
Tiled, metal, and flat concrete (RC) roofs each fail differently. We diagnose the actual leak path before recommending a membrane, coating, or PU injection system, so you’re not paying to redo a roof that never needed full replacement.
Hairline cracks, bubbling paint, and damp patches on boundary and parapet walls are common in older landed homes. We use thermal-imaging leak tracing to find the real source before sealing, rather than just patching the visible stain.
Seepage through driveway slabs and planter boxes often shows up as staining on the car porch ceiling below. We waterproof these structural areas to stop water travelling into the property from ground level.

Every landed home in Singapore is the owner’s responsibility from roof to ground. There is no MCST or town council to fix a leaking roof, so problems tend to grow unnoticed until a ceiling stain appears. The weak points differ by house type:
| House type | Where leaks usually start | What we typically do |
|---|---|---|
| Inter-terrace | Party-wall joints, shared roof gutters, rear flat roof extensions | Seal party-wall and gutter joints, re-membrane the flat roof |
| Corner terrace | Exposed side wall, parapet tops, flat roof edges | External wall coating, parapet capping seal, roof edge detailing |
| Semi-detached | RC flat roof, balconies above living rooms, planter boxes | PU or torch-on membrane, balcony re-waterproofing, planter box lining |
| Bungalow / GCB | Large flat roof areas, roof terraces, multiple drainage points | Full-roof membrane system, drainage correction, staged works |
Singapore gets heavy rain throughout the year, and landed homes have more exposed surface per household than any apartment. Three things drive most of the leaks we see:
Smaller landed-home jobs such as a single balcony, a section of external wall or a small flat roof start from S$900. Full flat roofs, bungalow roofs and whole-house packages are priced after the free inspection, because roof size, surface condition, access and the chosen system change the cost a lot. You always receive the price in writing before work starts.
Have the roof inspected every few years and after any leak. If the existing waterproofing is more than 5 to 10 years old, or you see ponding, cracks or ceiling stains, it is time for a professional check.
Often, yes. When the leak source is localised, we can repair it with targeted sealing or PU injection. We only recommend a full membrane when the existing system has failed across the roof.
Routine waterproofing repairs to your own landed property generally do not need approval. Structural changes are different, and we will tell you before work begins if anything needs to be checked.
NexTech Waterproofing landed-home jobs start from S$900. Larger roofs and whole-house work are quoted after a free site inspection.
A written warranty of 1 to 5 years, depending on the condition of the roof, confirmed in the quotation before work starts.
