Cleaning & moss removal à Wezembeek-Oppem
Moss removal by hand, brushing, anti-moss treatment and low-pressure rinsing. In Wezembeek-Oppem it is rarely an acute leak and almost always a roof at the end of its life.
13 km from our depot in Grimbergen
What that changes here
This is where maintenance pays best. Leaves and moss fill the valleys and send the water under the tiles. Cleaning always includes clearing the valleys and the gutters completely, not just brushing what can be seen from the street.
Wezembeek-Oppem continues on from Kraainem and Woluwe-Saint-Étienne: quiet districts, wide plots and many roofs from the 1960s and 1970s. It is typically the area where a roof is not broken but finished: the tiles have become brittle and the ridge tiles have worked loose.
What we get called out for in Wezembeek-Oppem
In Wezembeek-Oppem it is rarely an acute leak and almost always a roof at the end of its life. The tiles of the 1960s and 1970s have become brittle, the ridge tiles have worked loose and the roofing underlay — where there is one — has gone hard. It is not an emergency, but it is a conversation better not put off for five years.

Pour un devis, la visite à Wezembeek-Oppem se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 13 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Kraainem ou Woluwe-Saint-Lambert, 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.
