Custom window installation and replacement in Herstal (4040) and across the whole municipality, from the centre to Vottem, Liers and Milmort. A Liège team, a free on-site survey scheduled within 48h, and clear guidance on the Walloon grants you are entitled to — from working-class brick houses to the riverside buildings along the Meuse.
We work in Herstal from our depots in the Meuse valley, with a team of fitters who know the municipality — from the dense centre to the banks of the Meuse, from the working-class estates inherited from the arms industry to the residential districts of Vottem, Liers and Milmort.
The survey takes place at your home, with no call-out charge and scheduled within 48 hours ; the same team then follows the whole project, from taking measurements to installation and finishing.
We know the Herstal building stockBeyond Herstal itself, we also fit windows in Vottem, Liers, Milmort, Pontisse and La Préalle, as well as towards Liège and Visé via Oupeye and Bassenge — same team, same lead times across the whole lower Meuse.
Herstal falls under Wallonia grants. 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 more than 10 years old, VAT drops from 21% to 6% on supply and installation. Applied directly to your quote.
The Town of Herstal does not add a specific window grant on top of the regional support ; urban-renewal zones may, however, open up additional help. We check your address case by case.
The full breakdown of amounts, conditions and income ceilings is 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⭐️ »
