Hello, after we moved in we had a glass shower door installed and then a few months later the paint started to lift from the wall. After removing the paint and the kickboard we discovered
water soaking into the drywall and kickboard after a shower. I think the water is coming from the lower screw hole. Can I solve this without a whole shower demo? I've tried a few things but nothing has worked yet, specifically forcing silicone sealant into the screw hole.

Any questions I should be asking or answering?

Thanks, everyone
