Recently the wood transition strip at the door from my garage to the backyard came loose. When I pulled the transition strip it appears the underlying wood is rotted, how would I go about repairing this?
Edit: I'll say what what I know might be underneath. This is the ground floor. I don't believe out basement extends under any part of the garage. My garage has a tile floor installed by the previous owner (she ran a kennel out of house before we bought it so all the rooms, not just the garage, had this crazy tile!). I presume the tile is on top of concrete based on what I can see at other parts of the garage where the tile ends) The red brick is the outside of the house, and the pavers were installed directly on the dirt by the landscaper.
