Singapore waterproofing specialists · HDB · Condo · Landed · Commercial
Targeted diagnosis, durable membranes, and a ponding-tested handover — for Singapore homes, MCSTs, and commercial properties. Most callouts attended within 24–48 hours.
Two clear pathways
Whether it’s a single ceiling stain at home or a recurring leak across a condo podium, we scope, fix, and document the same way: properly.
HDB flats, condos, landed homes — bathrooms, balconies, ceilings, and roofs that leak when it rains or after a renovation.
Condominiums, offices, F&B, retail, light industrial, and education facilities — from leak audits to staged remedial works.
What we fix
Wet floors below, mouldering skirting, leaking shower kerb. We re-do the membrane and screed cleanly, with a real ponding test before tiling back.
Brown ring on the living-room ceiling that gets bigger after rain. We diagnose whether it’s an upstairs unit, a roof, or a pipe before quoting works.
Failed grout joints, blocked drains, and old membranes. We re-waterproof and re-fall the screed so water actually reaches the outlet.
Standing water after rain, blistered membranes, weed growth in cracks. PU, acrylic, or torch-on systems chosen by exposure and traffic.
Hairlines after a sun-and-rain cycle let water track behind the paint. PU injection plus elastomeric overcoat, scoped from a real survey.
Damp walls, efflorescence, salt staining. We assess negative-side vs positive-side treatment and choose materials that suit the substrate.

A note on pricing. Singapore waterproofing pricing varies with wall and floor area, substrate condition, height, access, and the system specified. Published industry ranges sit broadly at S$45–S$95 per sqm for membrane systems and S$840–S$1,900 for an HDB bathroom; complex roof, pool, or commercial scopes can reach S$8,500+. Our quotes are written after the on-site inspection so you only pay for what your property actually needs.
Why AquaShield SG
Membranes specced for tropical heat, humidity, and UV. We don’t use the same system on a north-facing balcony and a sun-exposed terrace.
Before, during, and after photos for every job. You see the substrate prep, the coats, and the ponding test — not just a finished floor.
24–48h water-stand tests where the scope calls for it — signed off before we tile back. No tiles down without a passing test.
Daily dust sheets and end-of-day cleanup as standard. Job schedules shared up front; we tell you when wet works are happening.
5–10 year workmanship warranty depending on the scope and system selected. Conditions are written into the quote — nothing hidden.
Scopes written to meet HDB renovation rules, MCST permit-to-work, and tenant operations — including night and weekend windows.
Our process
On-site inspection, moisture mapping, and (if needed) selective hack tests to find the actual leak path — not the visible stain.
Written quote with materials, sequence, timeline, dust and access plan, and the warranty terms tied to that specific scope.
Substrate prep, primer, two coats of the right membrane system, reinforced at corners, drains, and pipe penetrations.
24–48h ponding test where the scope demands it — you see the water level, the duration, and the result before anything is closed up.
Photo report, warranty document, and a maintenance note so you know what to check at the 6 and 12-month marks.

FAQ
Yes. We handle HDB bathroom, kitchen, service yard, and ceiling-seepage work. Where the leak source is the unit above, we can document the tracing so the upstairs party has the evidence they need for their own remedial.
Yes. For condo work we share method statements and permit-to-work paperwork with the MA in advance, and we schedule noisy or wet works around the MCST’s rules and the neighbours’ routines.
Most of our commercial wet-area and podium work runs in phased night and weekend windows. We can also stage hoarding so a section of the floor stays operational while we work next door.
The numbers reflect the ranges we quote most often. Real pricing depends on substrate condition, area, height/access, and the chosen system. Local Singapore benchmarks for membrane systems sit broadly at S$45–S$95 per sqm and S$840–S$1,900 for an HDB bathroom; your written quote follows our site inspection.
5–10 years on workmanship depending on system and scope. The warranty document spells out what’s covered (e.g. membrane failure under normal use) and what isn’t (e.g. third-party renovation damage). We’d rather you read it than be surprised.
For active leaks in Singapore we usually attend within 24–48 hours, often same-day if you call in the morning. The diagnostic visit is from S$88 and is waived if you proceed with works within 30 days.
Not always. Where we can isolate the failed area (e.g. shower kerb only), we re-do just that section. Where the membrane has failed broadly, we’ll be honest about it and quote a full re-do — with tile reinstatement quoted as a separate line so you can decide.
Island-wide. We service HDB estates, condominiums, landed enclaves, and commercial sites across all districts.
