Real estate represents value for generations. Yet while concrete and steel often endure for decades, the appearance of glass facades suffers from environmental influences, vandalism, or faulty maintenance. Dull surfaces, fine scratches, or etching from acid rain can quickly make a building look aged and neglected. For owners and institutional investors, the question then arises: Must the facade be renovated (replaced) for millions, or is there a more sustainable way?

In times when Switzerland is tightening its climate targets and ESG criteria (Environmental, Social, Governance) are becoming increasingly important in real estate valuation, glass replacement is often the last resort. We at Polygon Smart Repair offer with GLASSRESQ a solution that combines economic sense with ecological responsibility.

The Ecological Equation: Saving Embodied Energy

Did you know that the production of flat glass is extremely energy-intensive? When glass is replaced, not only is new glass produced, but the old glass must also be disposed of at great effort and transported over long distances. On-site restoration by our teams reduces the CO₂ footprint of the project by up to 95%.

From our headquarters in Wädenswil, we are driving this vision of sustainable restoration throughout Switzerland. We preserve what already exists and restore it to like-new condition.

Cost-Effectiveness: Your Budget Will Thank You

Replacing a facade during ongoing operation is a logistical Herculean task. Tenants are disturbed, scaffolding must be rented for weeks, and the noise level is enormous. Glass restoration by GLASSRESQ offers clear advantages:

• Cost: Up to 80% savings compared to replacement.

• Operation: No disruption to tenants, no relocation necessary.

• Time: On-site restoration is significantly faster and more flexible.

Whether you own an office building in Rotkreuz or manage a residential property in Dulliken – a clear, shining glass facade immediately increases market value and attractiveness for tenants.

A Second Life for Glass

Think Long-Term

Large construction sites in Switzerland are often busy and fast-paced. When concrete is poured for floors or ceilings, or walls are being plastered, it is almost impossible to prevent splashes or even a “concrete slurry spill” from reaching already installed windows. What many people underestimate is that concrete is highly alkaline (with a pH value above 12). When cement slurry dries on glass, it triggers a chemical process that microscopically attacks the glass surface. The result is a permanent dull spot known as glass corrosion.

It becomes particularly critical when people attempt to remove dried concrete mechanically using a scraper or a hard sponge. The sand particles contained in the concrete act like an abrasive, causing deep, irreversible scratches. At Polygon Smart Repair, we regularly encounter this type of damage on construction sites from Wädenswil to Geneva and know that this is a job for specialists with the right expertise.

Why Water Alone Is Often No Longer Enough

Once cement residue has become firmly bonded to the glass surface, conventional cleaning methods are no longer effective. The cloudy appearance is not simply sitting on the glass, it has already altered the surface structure itself. As a result, ordinary cleaning leaves the glass looking dull and hazy.

This is where GLASSRESQ comes in. Instead of relying on aggressive chemicals that could damage surrounding building materials or harm the environment, we use a controlled glass restoration process specifically designed to safely repair the affected surface.

The GLASSRESQ Method: Restoration Instead of Replacement

Our technicians begin by professionally neutralising the alkaline residues. The damaged glass surface is then carefully restored using a multi-stage precision polishing process that gently removes the affected layer.

• Result: The glass regains its original molecular smoothness and optical clarity.

• Benefit: No visual distortion and only a fraction of the cost of replacing the glass.

• Available throughout Switzerland: Whether you’re in Wetzikon, Ostermundigen, Mendrisio, or anywhere else in Switzerland, our mobile service teams respond quickly to minimise damage and restore your glass professionally.
