Best way to transition from the floor to the front or back door?

Q: I’m going to begin to install tongue and groove bamboo flooring in my house. What is the best way to transition from the floor to the front or back door? Currently both doors have an aluminum base beneath the door. Do I butt the flooring up to the aluminum door jam, or do I leave a space and use a transition?

What is the best way to cover the wood floor transition to door?

A: It depends on the height difference between the bamboo and the door sill. You might choose a flat or dome cap or a bevelled strip.
