Why Are My Windows Hard to Open or Close?

A window that fights you to open or close usually comes down to one of a few mechanical issues — some repairable, some pointing toward replacement.

• Paint buildup — layers of old paint sealing the sash to the frame is common on older wood windows and is genuinely repairable by carefully scoring and freeing the paint seal.
• Failed balances — the spring or weight-and-pulley mechanism that holds a double-hung sash in position can wear out, making the window heavy or unable to stay open. Often repairable by replacing the balance.
• Warped frame or sash — moisture damage can cause a frame to swell or shift out of square, binding the sash. This is harder to repair and often signals the frame itself has failed.
• Debris in the track — for sliding windows, dirt or debris buildup in the track is a simple cleaning fix, not a window problem at all.
• Worn crank mechanism — on casement or awning windows, a stripped or worn crank gear will need hardware replacement.

If cleaning the track or freeing paint buildup doesn't resolve it, and the issue is on a frame that's otherwise structurally sound, a repair technician can often address balances and hardware without full replacement.
