Somewhere, Water Is Going Where It Shouldn't. Let's Find Where.

• A water bill that jumped although nothing about your routine changed
• One patch of floor stays warm even with the heating off — classic sign of a hot-water or ondol loop leak
• The boiler needs re-pressurizing every few days
• The downstairs neighbor rings your bell holding photos of their ceiling
• A musty smell or dark edge creeping along baseboards or bathroom silicone
• A faint hiss inside a wall when the apartment is silent at night

Two-minute self-check: close every tap and water-using appliance, then look at your water meter (usually in the hallway cabinet or by the entrance). If the small dial still turns, water is leaving the supply line somewhere. Text us a photo of the meter and what you observed — it sharpens our diagnosis before we arrive.

• Fixed quote before work starts — you agree to the number first. If the scope turns out to be different mid-job, we stop and explain before anything continues.
• Same rates at night, on weekends and on holidays.
• Card payment accepted. Cash receipt or corporate tax invoice (세금계산서) issued on request.
• VAT 10% is quoted separately, and we tell you the VAT-included total before starting.

In Korean buildings, who pays depends on whether the leak started inside your unit or in the building's shared plumbing — and that is exactly what a documented detection establishes. Our findings summary gives you something concrete to hand your landlord or building office instead of a translated argument. The details are in the guide below.
