Damp treatment à Molenbeek-Saint-Jean
Diagnosis and treatment of rising damp, penetrating damp and condensation. 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 a Brussels terraced house damp comes from three sides: from above through the box gutter, from the side through the party wall, and from below through rising damp in the cellar. We only treat what comes from the roof, and we say so when the cause is elsewhere — paying for a facade treatment because of a leaking box gutter is the classic mistake.
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.
Molenbeek-Saint-Jean porte le code postal 1080 et se situe in the Brussels-Capital Region. Notre équipe part de Grimbergen, à 9 km : nous y planifions le traitement de l’humidité en même temps que les chantiers de Brussels, Jette et Anderlecht, pour qu’un déplacement serve plusieurs toitures.

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 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.
