This is the industry-standard solution. The glazier removes the existing glass unit from the frame and installs a new factory-sealed unit.
Failure Mechanisms and Economic Implications of Compromised Insulating Glass Unit (IGU) Seals in Residential and Commercial Glazing broken window seal
If your windows are still under warranty, call the manufacturer first. Many cover seal failure for 5–20 years. This is the industry-standard solution
The broken window seal is a failure of engineering physics caused by the relentless cycle of thermal expansion and contraction. While the aesthetic degradation—fogging and streaking—is the primary driver for repair, the unseen economic cost lies in the reduced thermal resistance of the building envelope. As energy codes become stricter and sustainability becomes a priority, maintaining the integrity of IGU seals is essential. Replacement remains the only method to fully restore the window's energy performance to its original specifications. Many cover seal failure for 5–20 years
