When you find rot underneath a door.

It's not uncommon to remove an exterior door and find damage that has been caused by water infiltration. Often the problem has been caused by the absence of pan flashings that would have protected the rough opening. Another part of the problem lies with manufacturers that use aluminum extrusions on thresholds that are impossible to seal with sealant.

I ran into this problem today and thought I would document the process to help anyone who runs into a similar situation. In this instance, I did not use a new pan flashing, since there is a 4" step to the cement below, I don't believe there will be a problem with water creeping back toward the subfloor. But repairing the damage and adding self-adhesive flashing tape to protect the rough sill will help this opening last a good long time.

Great documentation! I have run into the same situation, but termites. Yikes! I have stop work, get the owner, bear the bad news, and let them go from there. I can repair the boo boo, but termites are forever if not taken proper care of.
