Where is the problem?
Identify the exact pane, sash edge, sill, screen or trim joint rather than describing the whole room.
Start with the symptom, the part of the window affected and the condition of the surrounding opening before deciding on repair or replacement.

A request for “window repair” can involve insulated glass, sash operation, screens, perimeter sealing or a frame that is no longer serviceable. Clear observations help route the project to the right assessment.
