What makes the price of your windows vary
For the same surface area, two quotes can differ by several hundred euros. Here are the items that really carry weight.
- Material & range
PVC, aluminium or wood-aluminium, then entry-level or premium within each material: this is the first price lever.
- Dimensions & shape
The larger the glazed surface, the more the window costs. Curved, triangular or bespoke shapes raise the price.
- Type of glazing
High-performance double, triple, acoustic or safety glazing: glazing can swing the price by 15 to 30%.
Compare glazing types → - Removal & disposal
Removing the old windows, taking away and recycling the debris: a real item, especially on sealed frames or heavy renovation.
- Access & floor
A high floor, a frontage on a busy street or scaffolding required all lengthen the installation and weigh on the quote.
- Finishes & options
Two-tone colour, handles, tilt-and-turn, motorised shutters or screens, accessible thresholds: all options to be priced.

Your questions about window prices
How much does a window cost on average in 2026?
For a standard window installed with high-performance double glazing, expect around 450 to 700 € in PVC, 750 to 1 100 € in aluminium and 1 100 to 1 600 € in wood-aluminium. Large bays and patio doors cost more. These are indicative ranges, grants not deducted.
Does the price include installation and removal?
Yes. The ranges on this page are for an installed window, removal of the old one included and neat interior finishing. The quote details each item — supply, removal, installation, disposal — so there are no surprises.
What is the extra cost for triple glazing?
Triple glazing generally represents 15 to 25% more than high-performance double glazing. It is justified on a north-facing frontage, near a noisy road or for a low-energy target. We compare the Ug values and the extra cost to decide together.
Are the grants deducted from my invoice?
When possible, yes: we put together the grant file and deduct it directly from your invoice, with no cash advance on your part. Otherwise you receive it after the works. In both cases, the quote shows the estimated grant amount and the 6% VAT.
Is the quote chargeable?
No. The on-site survey and the priced quote are free and with no commitment. You receive a clear estimate, grants included, within 48 working hours.
Does the price depend on my region?
Window prices vary little from one region to another, but the grants differ greatly between Wallonia, Brussels and Flanders. It is mainly the net amount, after grants, that changes according to your municipality and income.
