I had looked at the adjustable threshold in the store, but was concerned about it running into the storm door. After looking some more online, it appears that they have some shorter thresholds that are less than 5". I will pick one up and take a look after work. If that is the case, I can just use my end cap and put that up to the threshold with the wood running underneath it.
I am only installing hardwood in the foyer and hallway for now, but plan to install more hardwood later on, so I am trying to make sure I install everything in the right direction to be able to easily do so. I am trying to avoid having to use thresholds in the middle of doorways. Does this look like I good floor layout?
Thank you again for your help!
