Symptoms
- Frame has a visible kink or bow
- Screen won't sit flat in the window opening
- Corners gap open
- Happened after it was leaned on or dropped
Likely causes
- CommonImpact or pressure damageScreens are lightweight aluminum and bend easily if leaned on, sat on, or dropped.
- PossibleImproper removal or reinstallationForcing a screen in or out at an angle can bow the frame.
- Less commonAge-related metal fatigueVery old aluminum frames can weaken and bend under normal handling.
What to do
- Lay the screen flat on a soft, protected surface like a towel on a table.
- Identify the exact bend point by comparing it to the straight sections.
- Apply gentle, even pressure with your hands to bend the frame back toward straight, working slowly.
- For a stubborn kink, use a rubber mallet and a wood block to tap the bend flat without denting the metal.
- Check the frame against the window opening periodically as you work to avoid overcorrecting.
- Reinforce a weak corner joint with a corner brace if the bend was at a joint and it feels loose.
- If the frame is cracked or the bend won't hold, it's more reliable to buy a replacement frame kit and re-screen it.
