Window call-out and repair in Brussels (1000) and across the whole Brussels Region, from the Pentagon to the Louise district. Broken or fogged glazing, a misaligned tilt-and-turn, tired seals, seized hardware: a Brussels team diagnoses on site and repairs rather than replaces whenever possible — from the old timber windows of the mansion houses to upper-floor apartments.
We carry out call-outs in Brussels with a team that knows the city and its building stock — from the Pentagon and the Grand-Place to the lanes of the Marolles, from the Sablon to the Dansaert district, from the Louise district to the European quarter, all the way to Laeken and the mansion houses of the upper town, where the old timber windows call for specific know-how.
The diagnosis is carried out at your home, with no call-out charge and scheduled within 48 hours ; we repair on site when possible and, if a part is missing, we come back with the right hardware or glazing. Our principle : repair rather than replace for as long as the window allows, including on upper floors and on listed façades.
Window faults — we know them wellNeed a call-out elsewhere ? See also our windows in Brussels and our window repair in Anderlecht. We also work in Ixelles, Saint-Gilles, Etterbeek, Uccle and Schaerbeek — same team, same lead times across the whole Brussels Region.
Good news : repairing a window does not qualify for a grant — but it also costs far less than a replacement. If the diagnosis shows that a window has reached the end of its life, we switch to replacement, and there you benefit from the Brussels-Capital Region grants (Renolution) and the reduced VAT.
Glazing only, seals, hardware, adjustments: a targeted repair qualifies for no grant but remains far cheaper than a full replacement. We price the repair first, always as a priority.
When repairing no longer makes sense, replacement with high-performance double or triple glazing qualifies for the Renolution grant, scaled across three income brackets and topped up for low-income households. We handle the application.
For a home more than 10 years old, VAT drops from 21 % to 6 % on supply and installation in the event of a replacement. Applied directly to your quote.
The full breakdown of amounts, income brackets and replacement conditions is on our window prices & grants page. For a repair, you pay only for the work ; for a replacement, we handle the entire Renolution application with no advance payment from you.

From a simple glazing change to a full replacement when the window has reached the end of its life, we tailor the work to the building and the budget. The options :
Fogged or broken glazing replaced without touching the frame: the most economical way to restore insulation, ideal for the old timber windows of Brussels homes.
See double glazing →When repairing no longer makes sense, PVC offers the best insulation-to-price ratio for terraced houses and everyday renovations in Brussels. Discreet foiled finishes for neighbourhood façades.
Discover PVC →Unsure about the state of your windows ? We diagnose on site and tell you plainly whether it’s better to repair or replace, with a costed quote to back it up.
All about windows →We schedule the home diagnosis within 48 hours anywhere in the Brussels-Capital Region. When the fault is common (seals, tilt-and-turn adjustment, a small piece of hardware), we often repair on that very visit; if a part or glazing has to be ordered, we come back quickly with the right item. Distance within Brussels or its neighbourhoods does not extend this lead time.
No, almost never. Mist between the panes signals a failed double-glazing seal: we replace the glazing only, without touching the frame, and the original insulation is restored. It’s far cheaper than a replacement and particularly suited to the old timber windows of Brussels mansion houses, which we prefer to keep.
Yes. Our technicians adjust and replace the hardware, strike plates, stays, handles and seals of most brands on the market, including on older windows. If the original part is no longer made, we find a compatible equivalent. Describe the fault and, if possible, the brand when you get in touch — it speeds up the work.
No: a repair (glazing only, seals, hardware, adjustments) does not qualify for a grant, but it also costs far less than a replacement. The Brussels-Capital Region Renolution grants, as well as the 6 % VAT for a home more than ten years old, only apply to window replacement with high-performance double or triple glazing. If the diagnosis shows that repairing no longer makes sense, we switch to replacement and handle the grant application.
Yes, completely: the call-out to your home in Brussels, the diagnosis of the fault and the costed quote are free and with no obligation. You only pay for the repair, once you have approved the work.
Describe the fault and your address : a Brussels team calls you back, schedules the free diagnosis and repairs rather than replaces whenever possible.
