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.
Schaerbeek is the municipality of the 1890-1910 town house: tall, narrow facades, ornate cornices, mansard roofs in slate and a box gutter that disappears entirely behind the cornice. Around Josaphat Park and in Terdelt the 1930s are added to that, and their concrete tiles are now reaching the end of their life.
What we get called out for in Schaerbeek
In Schaerbeek nine calls out of ten are about water coming in through the cornice. The town houses there have a box gutter running from wall to wall, often still in lead or in zinc with no expansion joint, with a timber deck underneath quietly rotting. The second most common request is the lower slope of the mansard: slates working loose one after another.

Pour un devis, la visite à Schaerbeek se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 7 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Evere ou Brussels, 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.
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.
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.
