Frameless Shower Stall Leak

The shower in my master bath is leaking. It’s a frameless shower stall and I noticed that the bottoms of the door frames (a pocket door to the bathroom, next to the shower) have swelled from leaking water.

My plumber came by to check it out and has determined that the door is causing the leak. Not sure if it’s just when the door opens or also when the shower is in use.

I need someone who renovates and installs bathrooms to look at it and tell me what can be done to fix this. I’ve called the contractor who renovated the house for the name of the man who did the original installation, but have not heard back from them and need to move on.

Any suggestions for someone reputable and who does good work? Thanks.
