Most modern homes have double-pane windows, designed with two pieces of glass and a layer of insulating gas (like argon) between them. Over time, exposure to heat, humidity, and weather can cause the seal around the glass to break.

This is called seal failure, and it’s especially common in Lowcountry homes where weather swings and humidity put constant pressure on windows. Schedule your appointment today!
