Window sash won’t stay up
The sash drops, tilts crooked, or will not hold its position.
Use window symptoms like drafts, leaks, stuck sashes, locks, condensation, rot, or broken hardware to find the right guide.

Start with the visible symptom, then use the hardware or leak guide that matches that exact failure.
The sash drops, tilts crooked, or will not hold its position.
Support the sash, control balance tension, match the shoe, and reset both sides level.
Match the balance type and restore support when the sash still drops after hardware checks.
