Frequently Asked Questions

We’ve taken the time to provide detailed answers to common inquiries, ensuring you have the information you need at your fingertips.

ALL FAQs
Do I need to replace the entire window frame if the double glazing has failed?

Absolutely not. This is a key point: replacing only the glass unit (IGU) is the most cost-effective solution. If your frame (wood, PVC, or aluminum) is structurally sound, we simply remove the old, failed unit and install a new, modern high-efficiency IGU. We save you the cost and hassle of full window replacement.

If you wipe the glass on the inside and the outside and the fogging or moisture remains, it is definitively between the panes. This is a sure sign that the perimeter seal has broken, and the insulating layer (usually Argon gas) has escaped. In Brussels' high-humidity environment, this is a very common issue that requires IGU replacement to fix.

Yes, significantly. The glass is the largest component of heat loss. Upgrading an older, sealed unit to a new HR++ (High-Efficiency) unit with better K-values immediately reduces your property's heat loss, which is a major factor in improving your final EPB rating. This is a smart investment in your home's energy future.

We offer full double-glazing repair service across all 19 communes, including Ixelles, Uccle, Saint-Gilles, Etterbeek, Schaerbeek, and Brussels-City. We aim for the quickest emergency response time for glass-related hazards across the region.

What is the cost of replacing a failed double-glazed unit in Brussels?

The cost depends on the size of the glass and whether you choose standard or high-efficiency HR++ glass. Simple residential IGU replacement can start from €250 to €450 per unit, with larger or specialized units (e.g., tempered, acoustic) costing more. We always provide a clear, upfront quote after measurement, ensuring you know the exact price before we start.

Yes. All our new Insulated Glass Units (IGUs) are covered by a standard 10-year manufacturer's warranty against seal failure and internal fogging. We stand behind the quality of our certified glass and our installation workmanship.
