Installation and replacement of made-to-measure windows in Brussels (1000) and across the whole Brussels Region, from the Pentagon to the Louise district. A Brussels-based team, a free on-site survey scheduled within 48h and clear guidance on the Renolution grants you are entitled to — from the grand townhouses of the upper town to the listed façades of the centre.
We work in Brussels with a team of fitters who know the city — from the Pentagon and the Grand-Place to the alleyways of the Marolles, from the Sablon to the Dansaert district, from the Louise district to the European quarter, all the way to Laeken and the grand townhouses of the upper town.
The survey is carried out at your home, with no call-out charge and scheduled within 48 hours ; the same team then follows the entire project, from taking measurements to installation and finishing, including planning-permission support for listed façades.
We know the Brussels building stockBeyond the Pentagon, we also install windows in Ixelles, Saint-Gilles, Etterbeek and Laeken, as well as towards Uccle, Anderlecht and Schaerbeek — same team, same lead times across the whole Brussels Region.
Brussels relies on the grants of the Brussels-Capital Region, grouped under the Renolution scheme. Here are the levers we help you identify and claim — we show you exactly where to apply and provide every supporting document.
For replacing windows with high-performance double or triple glazing, the amount is scaled across three income brackets. The grant is higher for lower incomes — we work out your bracket and guide you through the application.
For a home over 10 years old, VAT drops from 21 % to 6 % on supply and installation. Applied directly to your quote.
In a listed or protected Brussels zone, replacing windows may require a permit and compliance with planning rules: we keep the original divisions and colours and guide you through the procedures.
The detail of amounts, income brackets and conditions can be found on our window prices & grants page. You introduce the Renolution application yourself with Brussels Environment — we guide you through each step and provide all the documents you need (detailed quote, invoices and installation certificates).

« Nous avons fait appel à la société Wendows pour le remplacement de nos châssis. La différence par rapport aux autres sociétés c'est qu'ils ont pris le temps de faire une étude complète et de nous proposer les châssis qui correspondaient à notre maison et notre besoin. Leur but n'était pas de mettre un châssis et de clôturer un chantier pour en faire un autre. Nous avons été accompagnés dans tout le processus. Du devis, en passant par la prise de mesure et l'attente de livraison. Délais respectés. Je ne peux que recommander cette société. Rapport qualité prix professionnalisme +5⭐️ »

From economical PVC profiles to contemporary aluminium, we match the material to the building and the budget. Explore each range :
The best insulation-to-price ratio, ideal for terraced houses and everyday renovations in Brussels. Discreet foiled colours for district façades.
Discover PVC →Slim profiles and large bays, perfect for apartments in the Louise or European quarter. Acoustic glazing to maximise light while cutting out urban noise.
See aluminium →We schedule the survey at your home within 48 hours anywhere in the Brussels-Capital Region. Installation then depends on the made-to-measure manufacturing of your windows, usually a few weeks; the exact lead time is firmly confirmed as soon as you sign the quote. Distance within Brussels or its districts does not lengthen this lead time.
As Brussels falls under the Brussels-Capital Region, you benefit from the Renolution grants for replacing windows with high-performance double or triple glazing: the amount is scaled across three income brackets and increased for lower incomes. On top of that comes the 6 % VAT if your home is over ten years old. Note that these are not the Walloon grants. We help you identify this support and show you exactly where to apply; all the amounts are detailed on our prices & grants page.
Yes. Across the whole Brussels Region, we also install windows in Ixelles, Saint-Gilles, Etterbeek and Laeken, as well as towards Uccle, Anderlecht and Schaerbeek. Just give your postcode when requesting a quote and we will confirm a team is available.
No, it is our daily work in Brussels. In the Pentagon, at the Sablon and in protected zones subject to regional planning rules, replacing windows may require a permit: we keep the original divisions and slim profiles, choose colours approved by the municipality and guide you through the procedures, all while clearly improving insulation.
Yes, completely: the call-out to your home in Brussels, taking measurements and the costed quote are free and with no obligation. You pay nothing until you have approved your project.
Tell us your address and your project : a Brussels-based team calls you back, schedules the free survey and sets up your Renolution grants.
