Process of a frame installation project

The precise measurement of each opening determines the exact dimensions of the new frames, window by window, to ensure a perfect fit to the existing masonry.

The removal of old frames precedes the installation of new ones, with particular care taken to ensure the seal between the frame and the wall to avoid any residual thermal bridge.

A frame replacement project generally lasts one day per window, for a complete home treated in two to four days depending on the number of openings involved.

Glazing and acoustic performance

Beyond thermal gain, the choice of glazing directly influences the sound reduction achieved. Asymmetrical double glazing, with two different glass thicknesses, offers better acoustic attenuation than standard double glazing with identical thicknesses.

For homes most exposed to road noise, reinforced acoustic glazing is available in addition to standard thermal gain, with a cost increase that remains moderate compared to the comfort benefit obtained daily by the occupants.

Grants and VAT in Wallonia

The replacement of frames is eligible for Walloon housing grants, with amounts varying according to household income and the thermal performance of the new glazing installed.

The 6% VAT applies to these works in a home over ten years old, provided that the corresponding mention appears on the invoice from the registered contractor.

Oscillating or sliding opening: which choice?

The oscillating opening remains the most common in Belgium, combining a classic hinged opening with a tilting ventilation mode that secures ventilation even in the absence of occupants.

The sliding frame is particularly suitable for large openings leading to a terrace or garden, avoiding the clutter of a classic French door that opens inward or outward from the room concerned.

Replacing frames is also an opportunity to reconsider the existing opening type: a difficult-to-access French window can for example be replaced by a more practical and secure oscillating model for daily use.

Replacing window frames in a condominium

In a condominium building, common in the Lower Town and other central neighborhoods of Charleroi, replacing window frames that affect the exterior appearance of the facade generally requires the approval of the general assembly of co-owners.

A harmonization of colors and materials between different apartments is often imposed by the condominium regulations, a point to check before any commitment to order from the chosen supplier.

Partial replacement, yellowing of PVC and existing shutters

A partial replacement of window frames is entirely possible, starting for example with the windows most exposed to noise or cold, before addressing the rest of the home on a budget spread over time. The yellowing of PVC, which may have affected older generations of window frames, is now limited thanks to UV-resistant treatments integrated into modern ranges. As for existing shutters, their preservation after a frame change depends on the fixing system and their general condition; our teams assess this compatibility during the initial diagnosis to avoid unnecessary removal.

Material, glazing, and permits

PVC offers the best value for money for most projects, wood is suitable for older buildings to be preserved, and aluminum appeals with its sleekness for large bay windows. Triple glazing offers better thermal insulation, but its additional weight and higher cost do not always make it relevant depending on the orientation and use of the room. In the vast majority of cases, a simple declaration is sufficient to replace window frames if the new joinery matches the original material and color; the municipality takes over as soon as the appearance seen from the street changes.

Project timeline and assistance for a complete replacement

Generally, expect two to four days to replace all the window frames of a standard house, depending on the number of openings and the complexity of the finishes to be done. Some global energy renovation files combine the replacement of window frames with other insulation items, which increases the total amount of grants awarded by the Walloon Region.

Replace your window frames before next winter

A free diagnosis evaluates the condition of your current window frames and identifies priority openings before proposing a detailed estimate, window by window and without obligation.

From Couillet to Marcinelle, the same measurement and installation rigor applies to every project, regardless of the section of Charleroi concerned.

A window frame replacement is felt from the first days following the work: less noise, fewer drafts, and a heating bill that already starts to reflect the investment made.

Whether the project concerns a single window or all openings of the house, the same measurement rigor applies, for a perfect fit between the frame and the existing masonry.
