Thankyou all for your input. Water does seep under sill plate which I have to fix. I should had said threshold but it looks like everyone understood. Thanks for bringing that to my attention Dave_dj1
My shed concrete pad is 4' wider than my shed where I am to put a man door. Do you still put a sill door plate down? Right hand swing. Should I make it swing in or out? Any suggestions and or pics will be helpful.
Thanks
Ken
