How to properly seal entry door and protect floor?

TLDR: Water damage around entry door threshold, but also seems to be affecting bottom of casing/drywall near threshold on closer look. Do I need to seal any other areas to protect new casing/drywall from damage before finishing or will better weather proofing around door be enough? Replacing wood flooring with tile too. Hey everyone, I'm in the midst of a DIY job with renovating a mud room type area and need some advice. There is an ongoing issue with moisture (no flooding or pooling water noted since buying the house) and seems isolated to the bottom of the door. The door does have some gaps and you can see light coming through, and I figured that's the main source of the water damage to the floor. But there was definitely some mild water damage on the back of the baseboards/vertical casing I just removed and the drywall at the bottom corners of the doorframe. No other areas around the door jamb seem to be affected. We are going to rip out this flooring and replace with tile, so won't have to worry about the floor rotting anymore at least. How do I seal that area around the bottom of the door jamb though to protect the new casing/baseboards? Based on location, seems like potentially more is needed than just weatherproofing the door itself. I added pictures of the outside to see if there's any obvious sources. Please advise if I should seal anywhere else before putting in new baseboards/casing. TIA! submitted by /u/kireikirin249 [link] [comments]
