The most common window repairs are foggy insulated glass (a failed seal, fixed by replacing the sealed unit), windows that won't stay up (worn balances or springs), sliders that stick (rollers or a dirty track), and torn screens (re-screening). Most are straightforward repairs that don't require replacing the whole window.
Foggy window glass
Like sliding doors, dual-pane windows fog when the seal fails and moisture gets between the panes. It can't be cleaned — the sealed unit is replaced, restoring clarity and insulation. See our foggy-glass guide for how sealed units work.
Windows that won't stay open
A single-hung or double-hung window that slides shut on its own has worn balances or broken springs. Replacing the balance restores the window's ability to hold its position — a common, quick fix.
Sliding windows that stick
Sliding windows use small rollers in a track, just like patio doors. Cleaning the track and replacing worn rollers gets them gliding again. Avoid oily lubricants that attract grit.
Torn or damaged screens
Torn mesh is re-splined into the frame with new screen material, and bent frames can often be repaired. Pet-resistant mesh is available for durability in Florida homes.
