Upvc door threshold leaking.
Hi. I’m new here. I recently realised mould development in bottom internal corners of front south facing door. I investigated and unblocked drainage holes in frame. It’s draining well now but I noticed a leak still . So I recently put silicone in corner of front corners where threshold meets frame. This seems to have sorted the result on internal wall righthand side of door( looking from outside in) but still lots of damp internally on other side, as can be seen in picture. I have found that there is a leak under the threshold where a gap exists (red circled area in photo)but don’t think a sealant will fix. Not sure how to seal as it seems to be coming from the frame itself as I noticed it flowed out more when I ran water down drainage holes. Any suggestions would be appreciated.
