Cleaning & moss removal à Woluwe-Saint-Lambert
Moss removal by hand, brushing, anti-moss treatment and low-pressure rinsing. In Woluwe-Saint-Lambert two types of job alternate: the flat roof of an apartment block, with a general meeting, a managing agent and a schedule spread over several months, and the slope of an interwar house, where one call and one visit are enough.

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.
Woluwe-Saint-Lambert combines wide avenues lined with blocks from the 1960s and 1970s with, in the side streets, interwar houses. For us that means alternating between the large flat roofs of jointly owned blocks and the ordinary slopes of single-family houses.

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

Pour un devis, la visite à Woluwe-Saint-Lambert se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 10 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Kraainem ou Evere, 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.
