Request your window quote in Liège (4000) with complete ease : a free home survey scheduled within 48h, a detailed costed estimate with no obligation, and your Walloon grants calculated then deducted directly within the quote. You know exactly what you pay — no surprises, no advance payment.
In Liège, requesting a quote should cost nothing and commit you to nothing. You tell us your address and your project ; we schedule a free home survey within 48 hours, from Outremeuse to the Guillemins, from the heights of Cointe to Angleur.
On site, an adviser takes the exact measurements, guides you towards the right material and spots the grants you are entitled to. You then receive a costed, detailed and transparent quote — with the Walloon grants already calculated and deducted — to compare at your ease, with no pressure whatsoever.
What your quote includesComparing several cities ? Find our windows in Liège page for the ranges and installation, or also request your window quote in Namur. We draw up quotes throughout the province : Seraing, Herstal, Ans, Chaudfontaine and Visé — same 48h lead time for the survey.
Liège falls under the grants of Wallonia. Rather than leaving you to estimate them yourself, we cost this support according to your situation and deduct it directly from the quote — you read a net amount, not a promise.
For replacing windows with high-performance glazing, scaled to your income. We estimate your amount in the quote and point you towards an approved auditor if a housing audit is required.
For a home over 10 years old, VAT drops from 21% to 6% on supply and installation. It is already applied to the costed total of your quote.
The City of Liège does not add a specific window grant on top of the regional support ; some urban-renewal areas may open up additional help. We check your address before drawing up the quote.
The detail of amounts, conditions and income ceilings is on our window prices & grants page. Your quote builds in the costed estimate of this support : you compare on a net amount, not on a before-grants price.

Your quote can compare several materials to help you decide. Browse the ranges before requesting, or let our adviser guide you during the survey :
The best insulation-to-price ratio, often the most economical option on a Liège quote. Ideal for the town houses of Outremeuse and everyday renovations.
Discover PVC →Slim profiles and large bays for the villas of Cointe or the heights of Sainte-Walburge. We cost aluminium as a variant when light and slimness come first.
See aluminium →Understand the price ranges and the Walloon support before reading your quote : all the cost benchmarks and grant amounts in one place.
See prices & grants →Yes, completely. The visit to your home in Liège, taking the measurements, the advice on the material and the costed quote are entirely free. You pay nothing until you have approved your project — and nothing obliges you to do so.
We schedule the survey at your home within 48 hours everywhere in the Liège conurbation. The detailed quote is then given to you very quickly after this visit, generally within a few working days, time enough to cost each opening precisely and estimate your grants.
Yes. As Liège falls under Wallonia, we estimate the Habitation grant (scaled to your income) and apply 6% VAT if your home is more than ten years old, then we deduct this support directly from the total. The amount you read is therefore a net amount, after grants — not a before-support price.
No, never. Our quote comes with no obligation : you receive it, you compare it freely against others and you decide when you wish. Until you have signed, you are free, and no charge is billed to you.
Our window quotes in Liège clearly state their validity period, generally several weeks from issue. Beyond that, we update the costing free of charge if prices or your grants have changed, so you always decide on an up-to-date amount.
Tell us your address and your project : a Liège adviser calls you back, schedules the free survey and gives you a costed quote, with the Walloon grants already deducted.
