Hard Water Stain Removal


When hard water dries on glass, the mineral deposits left behind build up to leave stains on the surface. If left for too long, they can even cause permanent damage to your windows.

We use safe, effective methods of removing these mineral stains to restore windows to their original condition. For best results, quickly address the source of your hard water stains—a leak in the building, maybe—or schedule periodic cleaning with our team.
