Cleaning & moss removal à Molenbeek-Saint-Jean
Moss removal by hand, brushing, anti-moss treatment and low-pressure rinsing. In Molenbeek the first question is almost always access: narrow streets, no room for a scaffold, and a rear that can only be reached through the house.
9 km from our depot in Grimbergen
What that changes here
In town, cleaning is as much about the neighbours as about the roof. Water and dirt travel over the party wall, and the rinsing ends up on a pavement or a terrace. We protect the surroundings, work in calm weather and empty the gutters before the end of the job — otherwise all the loosened moss ends up in the downpipe.
Molenbeek is built dense and low: rows of two-storey workers’ houses, narrow plots, party walls touching one another and, at the back, a run of flat roofs over kitchens and workshops. The real work here is rarely on the slope: almost always at the verge and on the extension.
What we get called out for in Molenbeek-Saint-Jean
In Molenbeek the first question is almost always access: narrow streets, no room for a scaffold, and a rear that can only be reached through the house. Technically it is flat roofs over extensions and the junction between two buildings of different heights — exactly where the water gets in.

Low pressure only: the moss comes off, the tile stays

Pour un devis, la visite à Molenbeek-Saint-Jean se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 9 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Brussels ou Jette, cela peut aller plus vite. En cas de fuite active, nous venons d’abord bâcher et sécuriser ; le démoussage n’est chiffrée qu’ensuite.
Yes, and permanently. High pressure strips the surface, opens up the porosity and forces water under the overlap. The result: the moss comes back twice as fast and tiles work loose in the months that follow. We work by brushing and at low pressure, without exception.
On porous concrete tiles or aged fibre cement slates, a water-repellent treatment has a real effect and clearly slows the return of moss. On natural slate it is almost pointless: the stone absorbs practically no water. We tell you that on site rather than selling it on principle.
