Damp treatment à Woluwe-Saint-Lambert
Diagnosis and treatment of rising damp, penetrating damp and condensation. In Woluwe-Saint-Lambert two types of job alternate: the flat roof of an apartment block, with a general meeting, a managing agent and a schedule spread over several months, and the slope of an interwar house, where one call and one visit are enough.

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.
Woluwe-Saint-Lambert combines wide avenues lined with blocks from the 1960s and 1970s with, in the side streets, interwar houses. For us that means alternating between the large flat roofs of jointly owned blocks and the ordinary slopes of single-family houses.

Pour un devis, la visite à Woluwe-Saint-Lambert 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 Kraainem ou Evere, 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.
