What that changes here
In town houses the lofts are often converted and then poorly ventilated: condensation does more damage there than insects. We always check the vapour barrier and the air gap before drawing any conclusion about the state of the timber.
Vilvoorde combines a dense centre of terraced houses with a long industrial past. In the old core the box gutters sit concealed behind the cornices and are invisible from the street: those are precisely the ones that leak into the masonry for years before anyone notices.
What we get called out for in Vilvoorde
In Vilvoorde it is almost always water getting in somewhere without anyone seeing where. The concealed box gutters of the old core are the textbook case; we are also called regularly about party walls and about the junction between two buildings of different heights, where a badly made upstand takes the water straight inside.
Vilvoorde porte le code postal 1800 et se situe in the northern periphery of Brussels. Notre équipe part de Grimbergen, à 4 km : nous y planifions la charpente en même temps que les chantiers de Machelen, Grimbergen et Zaventem, pour qu’un déplacement serve plusieurs toitures.

Common questions
Pour un devis, la visite à Vilvoorde se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 4 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Machelen ou Grimbergen, cela peut aller plus vite. En cas de fuite active, nous venons d’abord bâcher et sécuriser ; la charpente n’est chiffrée qu’ensuite.
A curative treatment carried out properly protects for about ten years. But the real protection is ventilation: a dry, ventilated loft interests neither insects nor fungi. So we put the ventilation right at the same time as the timber.
Four signs should raise the alarm: fine sawdust at the foot of the timbers, exit holes a few millimetres across, timber that sounds hollow under a hammer, and a smell of fungus in the loft. None of them is visible from the ground — which is why we always go up.
