Repairs in Roosdaal (1760): Plomberie Van Molder is based in Lembeek, in the municipality of Halle, and works in Roosdaal, in Flemish Brabant. We also work in the villages of Borchtlombeek, Pamel, Strijtem.
A leak, no hot water, heating off or an unusual noise: tell us the symptoms, the brand and the model. The diagnosis targets the cause of the fault, not just its visible effect.
When the heating stops, hot water is slow to arrive or a leak appears, the priority is to understand the cause before replacing a part. We start from your observations (symptoms, the code shown, when it began) to guide the diagnosis and avoid unnecessary work.
