Made-to-measure window installation and replacement in Tournai (7500) and across Picardy Wallonia, from the listed historic centre to the banks of the Scheldt. A Tournai-based team, a free site survey scheduled within 48h and clear guidance on the Walloon grants you are entitled to — in the shadow of the Belfry as well as in the surrounding villages.
We work in Tournai and throughout Picardy Wallonia, with a team of fitters who know the city — from the historic centre around the Cathedral of Our Lady and the Belfry to the banks of the Scheldt, from the Saint-Brice district to the localities of Kain, Froyennes and Templeuve.
The survey is carried out at your home, with no travel charge and scheduled within 48 hours ; the same team then handles the whole project, from taking measurements to installation and finishing.
We know Tournai’s building stockBeyond Tournai itself, we also install windows in Kain, Froyennes, Templeuve and Saint-Brice, as well as towards Antoing, Péruwelz, Leuze-en-Hainaut, Mouscron and Ath — same team, same lead times across Picardy Wallonia.
Tournai falls under Wallonia’s grant 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 glazing, scaled to your income. A housing audit is required above a certain amount — we point you to an approved auditor.
For a home over 10 years old, VAT drops from 21% to 6% on supply and installation. Applied directly to your quote.
The City of Tournai does not add a specific window grant on top of the regional support ; however, urban renewal zones and listed surroundings may impose constraints. We check your address on a case-by-case basis.
The detail of amounts, conditions and income ceilings can be found on our window prices & grants page. You introduce the application yourself — 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⭐️ »
