Problem category
Moisture on the room side, outside surface, between panes, or around the opening. Location and timing change the likely next step.
Soon
Room-side condensation forms when a surface is cold enough relative to indoor moisture. Dry the accessible wet surface and reduce the moisture source, then assess ventilation, indoor humidity, glass and frame temperature, air leakage, and the broader enclosure if the condition persists.
ExplorePlanning
Outdoor-surface condensation can occur when the exterior glass is cooler than humid outdoor air. Confirm that the moisture is truly on the outside and not between panes or entering the opening; location and timing determine the next step.
ExploreSoon
Persistent moisture or haze inside a sealed insulated-glass space can indicate that the sealed unit is no longer performing as intended. A provider should determine whether glass-unit, sash, or complete-window work is available and appropriate for the exact product and condition.
ExplorePrompt Assessment
Visible or suspected mold around a window signals a moisture problem that should be addressed, but the window may not be the only source. Limit exposure, dry accessible wet surfaces when safe, and seek appropriate assessment for recurring moisture, hidden damage, extensive growth, or health concerns.
