Scratches Caused by Contractors – Who Is Liable and What Is the Solution?

Imagine the scaffolding at your new construction project is finally being dismantled. For the first time, light streams unobstructed through the large glass façades, and then you notice it: fine sanding marks left by the plasterer, scratches caused during cleaning, or stubborn splashes that were carelessly removed. The shock runs deep, as the final inspection is just around the corner. Who is now responsible? And does the pane really have to be laboriously replaced?

On construction sites across Switzerland, from St. Gallen to Geneva, this is one of the most sensitive issues. Contractors work under time pressure, and glass is a delicate material. However, today a scratch no longer automatically means that the entire window sash has to be replaced.

The Liability Trap: A Problem for Site Managers and Contractors

It is often difficult to prove who caused the scratch. Was it the plasterer while finishing the reveal? The painter during masking? Or the construction cleaning crew using an improper blade? In most cases, this leads to lengthy discussions between trades, delays in the schedule, and stress with the client.

This is where we come in at Polygon Smart Repair. With our GLASSRESQ brand, we offer a solution that defuses the conflict: we restore the surface so precisely that no replacement is necessary. This not only saves money, but also protects the nerves of everyone involved.

Polishing Instead of Replacing: The Gentle Revolution

Replacing a large fixed glazing unit is a major logistical effort: crane rental, suction lifters, a new pane, disposal of the old one – all while follow-up works are still ongoing. Our technique is different. Our mobile teams come directly to your construction site.

With the patented GLASSRESQ process, we grind and polish the damage out of the glass surface with pinpoint precision. The result? A visually flawless pane without distortion (lens effect). Whether you contact us at our headquarters in Wädenswil or have a project in another region of Switzerland, we operate nationwide.

Why GLASSRESQ is the Smarter Choice

Time savings: A restoration usually takes just a few hours, whereas the delivery time for specialty glass can take weeks.

Sustainability: We preserve the existing glass, avoiding unnecessary waste and CO₂ emissions from production and transport.

Cost: In most cases, restoration is up to 80% cheaper than a full replacement.

Document and Act

Don’t let scratches dictate the completion of your project. The first step should always be a professional assessment. We will inspect the site to determine whether restoration is technically feasible – which is the case in over 90% of situations.

Have you discovered scratches on your construction site? Don’t hesitate. Call us for a non-binding damage assessment. We help you complete your project handover without costly delays or disputes.
