Damp treatment à Wezembeek-Oppem
Diagnosis and treatment of rising damp, penetrating damp and condensation. 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
On the periphery damp often comes from outside and from above: an overflowing gutter, a failed flashing, a terrace built up too high against the facade. Our search always starts at the roof, not at the wall.
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.
Wezembeek-Oppem porte le code postal 1970 et se situe in the eastern periphery of Brussels. Notre équipe part de Grimbergen, à 13 km : nous y planifions le traitement de l’humidité en même temps que les chantiers de Kraainem, Woluwe-Saint-Lambert et Zaventem, pour qu’un déplacement serve plusieurs toitures.

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 traitement de l’humidité n’est chiffrée qu’ensuite.
It works well on solid masonry with an accessible joint. On a cavity wall, in natural stone or filled with rubble, it is trickier, and another approach is more honest. We say so beforehand, rather than injecting and hoping.
Then no injection will change anything. Condensation is a matter of ventilation, heating and thermal bridges. We tell you so, even if it means we have nothing to sell — it still costs you less than a pointless treatment.
