Detection is cheaper than opening the wrong wall. [Request an inspection](#request) Last updated: 2026-10-10 [Seepwise](/) arranges water leak detection in Singapore homes for leaks you cannot see: a damp patch with no obvious source, a water bill that keeps climbing, or a ceiling stain that does not match the bathroom above. The aim is simple: know exactly where to open before anything is hacked. ## What happens on the first visit A detection visit combines methods, because no single tool finds every leak: a moisture meter to map wet areas, a thermal camera to show the temperature pattern of water in walls and slabs, dye tests in floor traps and fittings, and pressure tests on concealed pipes to see whether they hold. You get a marked-up finding with photos and a recommendation for the right trade. ## Signs of a hidden leak - A water bill rising with no change in use - The sound of running water when every tap is off - A damp patch that stays the same size in dry weather - Warm or cold spots on a floor or wall - A ceiling stain that grows when the unit above is empty ## What each method tells you --- --- --- Moisture meter How wet a surface is, and where it is wettest Shows the symptom, not always the source Pressure test Whether a concealed pipe run holds pressure Confirms a pipe leak, not its exact point ## Why detection first saves money Hacking a floor or wall to look for a leak is the expensive way to search. A detection visit narrows it to the fitting, pipe run or wet area involved, so the repair opens one place instead of several. It also gives you the written finding that HDB, an MCST or a neighbour will ask for before agreeing who pays ([BCA Guide 13](https://www1.bca.gov.sg/docs/default-source/docs-corp-regulatory/building-maintenance-and-strata-management/bca_guide-13_water_seepage.pdf)). ## What is included - ✓Moisture map of affected areas - ✓Thermal imaging scan - ✓Dye tests on traps and fittings - ✓Pressure test on concealed pipes where needed - ✓Marked-up photos of the finding - ✓Recommended trade and method - ✓Written report for HDB, the MCST or a neighbour - ✓No hacking during detection ## Painting over it vs a quick fix vs a proper repair DIY Quick fix Proper repair Search method Guesswork Hack and look Meters, thermal, dye, pressure Damage to find it None or a lot Several openings None during detection Written finding No No Marked-up report Useful in a dispute No Rarely Yes Right trade sent Unknown Whoever came Plumbing, waterproofing or facade ## What it costs Detection is quoted as a visit; the repair is quoted separately once the source is confirmed.

[Request an inspection](/contact/#request) ## Questions people ask How do you find a hidden water leak without hacking? + By combining a moisture meter, thermal imaging, dye tests on traps and fittings, and pressure tests on concealed pipes. Together they narrow the leak to one place before anything is opened. Is leak detection worth paying for? + Usually, because it replaces exploratory hacking and produces a written finding for HDB, an MCST or a neighbour. My water bill is high but I see no leak. What now? + Turn off every tap and watch the meter. If it still moves, water is escaping somewhere: a detection visit with pressure testing finds which run. Can detection prove the leak is from upstairs? + Dye and moisture tests can show whether water from the unit above reaches your ceiling, which is the evidence most disputes turn on. Is there a charge for sending a request? + No. Sending a request costs nothing. The specialist explains any inspection fee before the visit. ## Related services [Ceiling leak repairFind where the water enters, fix it at the source, and know who pays before work starts.](/ceiling-leak-repair/)[Water seepage repairBubbling paint and white powder on a wall are water moving through it.
