What to Consider: Repair or Full Replacement

Inside every IGU is a spacer and sealant system that creates the thermal gap and holds back water vapor. With seal failure, the unit inhales moisture on muggy days and exudes it as a fog when the glass cools, often leaving stains. Polishing the inside face is impossible without disassembly, which most residential IGUs are not designed to allow.
