For homeowners
Residential Waterproofing in Singapore
Hydroseal waterproofs condominiums and landed homes across Singapore, fixing roof leaks, bathroom and balcony seepage, and cracked external walls. Since 1995 we have diagnosed the true source of the leak, treated it with the right system for our tropical climate, and backed every job with a Certificate of Warranty.

Problems we solve for homeowners
Ceiling leaks & roof dripping in the rain
Stains that reappear every monsoon usually trace back to a failed roof membrane or ponding above, often a different spot from where the water shows inside.
Bathroom seepage to the unit below
A failed waterproofing membrane under the floor screed lets water reach the ceiling downstairs. We offer both hacking and non-hacking (PU grouting) repairs.
Balcony & planter water ingress
Popping tiles, damp skirting and inter-floor seepage from balconies and roof gardens, where drainage and membrane detailing matter most.
Cracked, damp external walls
Hairline cracks and porous render let driving rain through. We inject, seal and re-coat, reaching high-level walls by rope access where needed.
How we waterproof a home
We match the system to the problem and the surface, there is no single product that fixes every leak.
Free leak diagnosis
On-site inspection and moisture mapping to trace the water to its source before any work begins.
PU grouting & injection
Polyurethane injected into cracks and slabs to seal active leaks, the basis of most non-hacking repairs.
Torch-on membrane
Heat-bonded bituminous membrane for flat roofs and decks, a proven, long-lasting waterproofing layer.
Cementitious & crystalline
Coatings that bond into concrete and self-seal hairline cracks, ideal for bathrooms, planters and pools.
Certificate of Warranty
Every completed job is documented and warrantied from 1 to 10 years depending on the system.

How we work
One clear process, start to warranty
The same disciplined method on every job, so you always know what happens next and why.
- 01
Diagnose
A free, no-obligation site inspection. We trace the water path to its true source, not just where the stain shows, using moisture mapping and, where needed, rope-access close-up survey.
- 02
Recommend
A clear written recommendation matched to your building, budget and timeline: the method, why it suits Singapore’s climate, what it costs, and how long it lasts.
- 03
Execute
Our trained crews carry out the works with minimal disruption, surface preparation, treatment and protective coating done to specification, with safety and tidiness on site.
- 04
Document
You receive a photographic record of the works and, for façade inspections, a full condition report, the documentation facility managers need for BCA and building records.
- 05
Warranty
Every completed project is backed by a Certificate of Warranty, from 1 to 10 years depending on the system, so the result is protected long after we leave.

Common questions
Straight answers to what homeowners and building managers ask us most.
With the right system and proper preparation, a professional waterproofing job typically lasts 5-10 years, and often longer. Our work is backed by a Certificate of Warranty of 1-10 years depending on the system used. Singapore’s heavy rain, humidity and UV shorten the life of cheap or poorly applied coatings, which is why surface preparation matters as much as the product.
