How we find the leak
We start at the water meter. If it keeps running with every tap closed, the leak is in the supply pipe. Then we use a moisture meter, a thermal camera and, for hidden pipes, sometimes tracer gas. With that gas we can find a leak under a tiled floor to within a few centimetres.
If the stain is under a bathroom, the cause is often simpler. A cracked seal along the bath, or a trap that's come loose.
Old pipes in the city centre
Many houses in the Vijfhoek, the Leidsebuurt and around the Kenaupark still have lead water pipes. They leak more often, and lead in drinking water isn't healthy. If we come across them, we'll tell you. Replacing them with copper or plastic usually takes one or two days.
