Facade renovation & cleaning à Zaventem
Cleaning, repointing, water repellent and facade render. In Zaventem it is striking how many enquiries concern what sits under the tiles.

What that changes here
In the shade of trees the north facade goes green and damp sits at the foot of the wall. The anti-algae treatment and the clearing of the vegetation are part of the job: otherwise the new finish goes green before the guarantee runs out.
Zaventem lives with the airport: over the decades many houses have had extra insulation and acoustic work carried out in the roof. That work was not always done carefully, and we regularly find a crushed air gap or a missing vapour barrier.
What we get called out for in Zaventem
In Zaventem it is striking how many enquiries concern what sits under the tiles. Over the years many roofs have had an extra layer of insulation or acoustic work; we get called when damp gets involved. Alongside that, the ordinary work: gutters, roof windows and slopes at the end of their life.
Zaventem porte le code postal 1930 et se situe in the northern periphery of Brussels. Notre équipe part de Grimbergen, à 9 km : nous y planifions la rénovation de façade en même temps que les chantiers de Kraainem, Machelen et Wezembeek-Oppem, pour qu’un déplacement serve plusieurs toitures.

Common questions
Pour un devis, la visite à Zaventem se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 9 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Kraainem ou Machelen, cela peut aller plus vite. En cas de fuite active, nous venons d’abord bâcher et sécuriser ; la rénovation de façade n’est chiffrée qu’ensuite.
A facade treatment carried out properly lasts fifteen to twenty years. West and south-west gables, which take the driving rain, age noticeably faster: it is common to redo them on their own between two full campaigns.
If the masonry is sound and the brick good-looking, repointing followed by a water repellent is still the best choice: you keep the character of the facade. If the substrate is mixed, cracked or badly repaired, a render rebuilds a single surface. The diagnosis decides, not the starting budget.
