Subfloor Issues and Remedies

The floor under the hardwood floor in the playroom is in bad shape.  There is some rot, Justin thinks was caused by a kitchen sink (there are plumbing holes by the rotted area).  There are some strange wear patterns that hint to a completely different configuration of the room.  (Note that the varnish where Evelyn is standing is still intact, and the floor around it worn lower.)

The other issue is that the playroom floor and the new addition don't line up exactly.  If left alone, the new plywood floor would be 1/4" lower than the addition plywood at one end and 3/4" higher at the other end.  Justin decided it would best to remove the subfloor in one section to be able to create a level floor.  (It was the rotten bit anyway.)

Hello basement.

Justin had to install new sistered joists (carefully over Colin's wiring), especially near the wall because the joist is under the living room wall.

Beautifully level and all ready for new oak flooring.
