If the screen frame isn’t broken, you can replace the screen mesh yourself. Using a small flat blade screwdriver, remove the spline from the channel. It may be glued in spots, but you can work it loose by picking at it. Then remove the mesh. Use new mesh cut about an inch larger than the frame and work the spline back into the channel, keeping the mesh taunt.
The Pet Screen material I used is slightly heavier than RV screen, but I got it to work with a little effort.
