Windows bowing out at joining--any advice welcome.

About two years I had my handyman remove an odd sized vinyl picture window and replace it with two double hung vinyls. He has retired and moved out of state.

Some time ago I noticed that the window frames are bowing out toward the center where the windows were joined, from nothing to 1/2 inch where the windows meet. There is no bowing at the top.

Any suggestions as to what I should do? I assume that the window was installed too tight and that's why this is happening. I would like to avoid ripping the window out.

There could be multiple reasons for such bowing.

1.) Cheap windows - Poorly manufactured
2.) Improperly installed windows - Too large for the opening, impoperly fastened, etc.
3.) Window header is sagging, or non-existent.
4.) Moisture damaged causing the header or other framing to swell, or rot.
5.) Other....

Things to check for

I would have to agree, Pictures would be helpful. On another note a question? You stated that there is no gap at the top of the mull (which is where the installer and/or factory " joins Multiple windows together) do you have a gap at the bottom? Senario 1. I would say the the window may have been installed into an opening too small in height for the window itself. Causing the frame to bow out.
Senario 2. Window installed in a opening that is too wide, causing the window to pull away from the mull.
Again without seeing it thats what I can think of off the top of my head, I would defintely get them back out for fear of water intrusion.

Good Luck,
