Damp treatment à Brussels
Diagnosis and treatment of rising damp, penetrating damp and condensation. In the City of Brussels half the work is done before anyone goes up onto the roof.
10 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.
The City of Brussels runs from the Pentagon to Laeken and Neder-Over-Heembeek: medieval plots with very narrow, very tall houses, 19th-century town houses with concealed box gutters, and further out post-war blocks with flat roofs. On a single job you come across everything — except room to work.
What we get called out for in Brussels
In the City of Brussels half the work is done before anyone goes up onto the roof. Access, permits, occupation of the pavement, the managing agent’s approval: that route sets the schedule. Technically it is most often box gutters, upstands against the neighbouring facade and extension flat roofs — rarely a complete slope.
Brussels porte le code postal 1000 et se situe in the Brussels-Capital Region. Notre équipe part de Grimbergen, à 10 km : nous y planifions le traitement de l’humidité en même temps que les chantiers de Molenbeek-Saint-Jean, Schaerbeek et Ixelles, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Brussels 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 Molenbeek-Saint-Jean ou Schaerbeek, 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.
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.
By its height and its regularity: a horizontal band eighty centimetres to over a metre high, even along the whole length of the wall, often with salt efflorescence and plaster coming away. If the stain appears after rain and sits higher up, it is penetrating damp.
