Start by separating the problem into glass, moving parts, and frame condition. Each can point toward a different solution.
Look at how the window operates.
If the sash sticks, drops, or will not lock, the problem may involve balances, operators, alignment, or hardware. A targeted repair can sometimes address this when parts are available and the structure is sound.
Look at the glass.
A cracked pane or fog between insulated panes may call for a glass replacement. A sound frame does not automatically need to be discarded because the glass unit has failed.
Look at the surrounding structure.
Visible rot, deformation, persistent leaks, and significant damage may make a larger replacement more appropriate. Moisture problems should be understood before a new unit is selected.
Compare scope, not just price.
Ask what is included: glass or the full unit, installation, finishing, disposal, and any related repairs. Confirm warranties for the actual product and work described.
