Window won’t open or close
A stuck window is usually paint sealing the sash shut, a broken sash cord or balance, or humidity-swollen wood or aluminum corrosion — all common on Casselberry's older window stock and all repairable without replacing the window.
What is most likely wrong
| # | Cause | How common | What it looks like |
|---|---|---|---|
| 1 | Painted shut | Very common | Paint has sealed the sash to the frame, especially on older wood-trim windows repainted multiple times over decades. |
| 2 | Broken sash cord or balance | Common on older double-hung windows | The window will not stay up on its own, or feels heavy/uneven when moved. |
| 3 | Humidity-swollen wood | Common in Florida | The sash sticks in the track during humid months and frees up in drier ones. |
| 4 | Track corrosion or debris | Common on older aluminum frames | Gritty or grinding resistance when sliding, often with visible white corrosion on aluminum frames. |
What you can safely check yourself
- Look for a visible paint seam along the sash edge and score it carefully with a utility knife before forcing the window.
- Check whether the window stays open on its own or falls — a sign of a broken balance or cord, not something to force.
- Clean visible debris from the track and try a dry silicone lubricant before assuming the window needs replacing.
If any of this involves opening an electrical panel, running new wiring, cutting into a gas or water line, or working higher than a stepladder safely reaches, stop and call a licensed tradesperson — that is not handyman-scope work, regardless of how small the fix looks.
Why this happens in this housing stock
A meaningful share of Casselberry’s pre-1990 housing (57.1% of parcels built 1970–1989, plus 19.9% built before 1970) still carries original or first-generation windows. Sustained humidity here makes wood swelling a bigger factor than it would be in a drier climate.
What the fix typically costs
| Job | Researched range | What drives it |
|---|---|---|
| General window repair | $234–$636 | Hardware/weatherstripping vs. sash or balance work. |
