Roof insulation à Molenbeek-Saint-Jean
Insulation of pitched roofs and lofts, from the inside or as sarking. In Molenbeek the first question is almost always access: narrow streets, no room for a scaffold, and a rear that can only be reached through the house.
9 km from our depot in Grimbergen
What that changes here
The Brussels loft is narrow, tall and awkward to get to; everything goes up by hand through the stairwell. In a subdivided building there is also the question of who pays for what. Technically we watch above all the airtightness around the dormer and the junction against the party wall: those are the two places where damp comes back.
Molenbeek is built dense and low: rows of two-storey workers’ houses, narrow plots, party walls touching one another and, at the back, a run of flat roofs over kitchens and workshops. The real work here is rarely on the slope: almost always at the verge and on the extension.
What we get called out for in Molenbeek-Saint-Jean
In Molenbeek the first question is almost always access: narrow streets, no room for a scaffold, and a rear that can only be reached through the house. Technically it is flat roofs over extensions and the junction between two buildings of different heights — exactly where the water gets in.

Pour un devis, la visite à Molenbeek-Saint-Jean 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 Brussels ou Jette, cela peut aller plus vite. En cas de fuite active, nous venons d’abord bâcher et sécuriser ; l’isolation de toiture n’est chiffrée qu’ensuite.
In most cases, yes: the insulation is fitted from the inside. Sarking — insulation laid over the roof structure, under the tiles — is only justified if the roof has to be redone anyway. In that case it is the best solution, and the question comes up before the tiles are ordered.
The Flemish and Brussels grants change every year and depend on your situation, the dwelling and the contractor. We supply the invoices and technical data sheets required; the application is made to the relevant body. We do not quote amounts that will no longer be valid in six months.
