Factors influencing the cost of window installation
The installation price of windows in Belgium varies according to several criteria. Whether in the context of an energy renovation or a new construction, you need to budget for the purchase of materials and labor.
The glazing directly influences the purchase price of a window, as it determines its energy and acoustic efficiency. Depending on your needs and the desired performance, several types exist:
- Single glazing, now rarely used, offers little insulation but is economical.
- Double glazing, the most common, provides a good balance between insulation and cost.
- Triple glazing, ideal for passive houses or very cold areas.
In Belgium, double glazing is the standard to meet thermal insulation requirements. Triple glazing, more efficient, is recommended for homes exposed to noise or low temperatures. Some models also benefit from reinforced insulation glazing or argon gas, further improving their energy performance.
Belgian windows are generally made from PVC, aluminum, or wood, sometimes in a wood/aluminum mixed version.
- PVC is very popular due to its excellent value for money and easy maintenance.
- Wood, natural and warm, offers very good insulation but requires regular maintenance.
- Aluminum is favored for its durability, modern design, and weather resistance, although it is a bit more expensive.
Each material affects the final price and the installation technique used by the craftsman.
The number of panels impacts the purchase and installation cost. A single-panel window costs less than a two or three-panel model but offers less opening. The choice therefore depends on both your lighting needs and the configuration of your rooms.
The size of the windows directly influences the overall budget. The larger the glazed area, the higher the price due to the additional materials and glazing required. At Avenir Rénovations Belgium, our carpenters take the exact measurements of your openings to provide you with a custom quote at the best price.
The opening system is another determining factor in the price of a window. In Belgium, the most common models are:
- casement windows, classic and affordable;
- tilt-and-turn windows, practical but more expensive;
- sliding windows or pocket windows, ideal for large glass doors;
- hopper windows, often used in humid rooms.
The more complex the mechanism, the higher the installation price will be.
The cost of labor depends on the number of windows, the chosen installation method, and the complexity of the project. In Belgium, the average rate for installing a window ranges from €100 to €500, depending on the size and technique used.
Avenir Rénovations Belgium provides you with qualified craftsmen for impeccable work at the most fair price.

Cost of window installation by materials
The choice of material strongly influences the final price. Each option has its advantages in terms of performance, aesthetics, and durability.
Price of PVC window installation
PVC offers excellent value for money, good thermal and acoustic insulation, and minimal maintenance.
Estimated price: between €250 and €600 VAT included (installation included).
Price of wooden window installation
Wood is appealing for its natural charm and insulating qualities but requires regular maintenance to withstand the elements.
Estimated price: between €400 and €1,000 VAT included (installation included).
Price of aluminum window installation
Aluminum is modern, durable, and does not rust. Its lightness makes handling easier, but its thermal insulation is lower than that of wood or PVC, unless with thermal bridge break.
Estimated price: between €300 and €800 VAT included (installation included).
Price of mixed wood/aluminum windows
Mixed models combine the warmth of wood on the inside and the durability of aluminum on the outside. Their price is higher, but they offer excellent longevity and a high-end finish.
Estimated price: between €500 and €1,200 VAT included (installation included).
Installation rates by type of glazing
Glazing plays a crucial role in the energy and acoustic performance of your windows. Depending on the chosen technology, the installation price can vary significantly. Here is an estimate of the average costs in Belgium based on the most common types of glazing.
Price of a double-glazed PVC window with installation
Double glazing offers thermal and acoustic insulation far superior to that of single glazing. It consists of two panes separated by an air or insulating gas layer, ensuring better energy efficiency. The price depends on the type of joinery and the glazed area.
In Belgium, the price of a PVC window with double glazing, installation included, ranges between €300 and €800 VAT included.
Cost of installing a triple-glazed window
Triple glazing offers even more effective insulation against both cold and noise. Its higher cost is due to its reinforced structure, although it is not always necessary in temperate climate areas. It is particularly recommended for homes located in cold regions or areas with high noise exposure.
The price of a triple-glazed window, installation included, varies between €600 and €1,200 VAT included.
Window Replacement Costs According to Installation Method
The installation of windows can be done using several methods, each having a direct influence on the total cost of the work.
Renovation Installation
This method involves keeping the old frame (the reveal) to attach the new window. It is quick and economical.
Surface Mounting
The window is fixed onto the masonry, providing excellent sealing and better thermal performance, but at a slightly higher cost.
Total Removal
This involves completely removing the old frame before installing the new joinery. It is the most effective method, but also the most expensive.
Grants and Subsidies for Window Replacement in Belgium
In Belgium, several regional grants and subsidies help to reduce the cost of replacing your windows, especially if the work improves the energy performance of the home.
Regional Energy Grants (MaPrimeRénov’)
Each region (Wallonia, Brussels-Capital, Flanders) offers Energy grants to encourage insulation work and the replacement of frames.
- In Wallonia, the grant for installing high-performance windows can reach €0.15 to €0.90 per kWh saved, depending on household income.
- In Brussels, the grant ranges from €50 to €150 per m² of insulating glazing, depending on the performance achieved.
Reduced VAT Rate of 6%
Renovation work carried out in a private home over 10 years old benefits from a reduced VAT rate of 6% (instead of 21%). This reduction applies to both materials and labor.
Energy Loan at Favorable Rates
Some regions offer low-interest or zero-interest loans to finance insulation and energy renovation work, including window replacement.
By combining these assistance and grants, the cost of your new windows can be considerably reduced while improving the energy efficiency of your home.
