Damp treatment à Overijse
Diagnosis and treatment of rising damp, penetrating damp and condensation. In Overijse every job starts with the same question: how to get to it.
21 km from our depot in Grimbergen
What that changes here
On the periphery damp often comes from outside and from above: an overflowing gutter, a failed flashing, a terrace built up too high against the facade. Our search always starts at the roof, not at the wall.
In the grape region the houses often sit on a slope, on the edge of the Sonian Forest. That means long roof slopes, a lot of leaves and access that is far from straightforward for a scaffold. We plan these jobs with access as the first question, not the last.
What we get called out for in Overijse
In Overijse every job starts with the same question: how to get to it. Houses on a slope, curving drives, gardens running up to the forest — access sets the schedule here and sometimes the method itself. Then comes the usual: long slopes, heavy leaf fall, valleys that block up.

Pour un devis, la visite à Overijse se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 21 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Wezembeek-Oppem ou Kraainem, 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.
