Water-repellent treatment & coating à Ixelles
Clear or coloured water repellent for porous tiles and facades. In Ixelles we are mainly called for two things: the zinc work on the old grand town houses — dormers, valleys, domes, junctions against the neighbouring facade — and the flat roofs of post-war blocks, where it is the managing agent who decides and the paperwork takes longer than the job.

What that changes here
On a Brussels roof slope a water repellent adds little: the slopes are small, often in natural slate, and the real leak is in the box gutter. We advise against it here most of the time, and we say so. On the concrete tiles of the post-war districts in Evere or Anderlecht the conversation is different — there it is justified.
Around the ponds and in the Louise district is the most carefully built stock in the city: grand town houses from the late 19th century, Art Nouveau, natural slate, zinc dormers and a great deal of detail work. Further out, the 1960s apartment blocks and their flat roofs dominate. Two worlds, two techniques.

Pour un devis, la visite à Ixelles se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 12 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Brussels ou Uccle, cela peut aller plus vite. En cas de fuite active, nous venons d’abord bâcher et sécuriser ; le traitement hydrofuge n’est chiffrée qu’ensuite.
On a porous brick or render, yes, and it is often the cheapest way to stop damp coming through a west-facing gable. The condition is the same: a clean, dry surface, and the cause dealt with first — an overflowing gutter, for example.
Applied properly on a clean, dry surface, allow eight to ten years on a roof and five to eight years on a facade exposed to westerly rain. The first sign of wear is easy to spot: the water no longer beads, it spreads out and darkens the material.
