What’s included in our leak detection services?

Depending on the suspected source of the water loss, we use professional non-destructive methods such as thermal imaging, tracer gas, acoustic leak detection, pressure testing and pipe or sewer camera inspection. These techniques help locate a hidden or concealed leak while avoiding unnecessary opening of walls or floors.

Our technician carries out an on-site diagnosis. When the selected service includes a report, a technical report is prepared with the findings and can be added to an insurance claim file.

Hydro Therm operates across all 19 communes of Brussels, as well as in Flemish and Walloon Brabant. In Flemish Brabant, our service area includes Zaventem, Vilvoorde, Tervuren, Wezembeek-Oppem, Overijse and Grimbergen. Appointments and urgent interventions are available 7 days a week.

Moisture Detection and Diagnosis

Moisture does not always come from a leaking pipe. Depending on the situation, the cause may be a hidden water leak, infiltration, condensation or rising damp. Moisture measurements, visual checks and non-destructive leak detection methods can help identify the affected area and determine whether further leak investigation is required.

If you are looking for affordable leak detection in Brussels, compare the cost based on the investigation methods included, the time required to locate the leak and whether a technical report for insurance is needed.

Accepted payment methods

We accept cash or instant bank transfer after the intervention.
