Diagnosis and treatment of rising damp, penetrating damp and condensation. In Jette the interwar roofs are starting their second life.
7 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.
Jette is largely interwar: terraced and semi-detached houses from the 1920s and 1930s, in clay tile or first-generation concrete tile, with dormers added later. Towards the Laerbeek wood the gardens get bigger and the slopes become shadier.
What we get called out for in Jette
In Jette the interwar roofs are starting their second life. We are called about tiles that have become brittle, about dormers added later and never properly flashed in, and about gutters giving up after eighty years. Rarely an emergency, often a roof that is finished.

Pour un devis, la visite à Jette 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 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.
