What that changes here
Under trees a water repellent makes little sense if the roof is covered in leaves again within the year. We only apply it after a full clean and a clearing of the surroundings, and we say plainly that it does not replace the annual gutter maintenance.
Our depot is on Vilvoordsesteenweg, so Grimbergen is the municipality where we work most often. It is the typical periphery: a great many detached and semi-detached houses from the 1960s to the 1990s whose roof coverings are reaching the end of their life all at once, and many flat roofs over extensions and garages.
What we get called out for in Grimbergen
Grimbergen is the municipality where we work most often, and it shows in the lead time: our depot is here. Most enquiries concern roofs from the 1970s and 1980s that have reached their first real renovation, and the flat roofs over the garages, verandas and kitchens built at the back of the house.

Pour un devis, la visite à Grimbergen se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 0 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Meise ou Vilvoorde, cela peut aller plus vite. En cas de fuite active, nous venons d’abord bâcher et sécuriser ; le traitement hydrofuge n’est chiffrée qu’ensuite.
The clear product changes nothing about the appearance: it is the default choice, and the only one allowed in a protected area. The coloured product evens out a covering whose colours have drifted after successive repairs. It does not rescue a covering at the end of its life — it disguises it, and we will tell you so.
On a porous brick or render, yes, and it is often the cheapest way to stop damp coming through a west-facing gable. The condition is the same: a clean, dry surface, and the cause dealt with first — an overflowing gutter, for example.
