No sub floors in 60 year old homes

What happens here

This video demonstrates the initial demolition phase of a subfloor repair project in a bathroom. It details the systematic removal of old underlayment and existing subfloor material using a circular saw and pry bars. This preparatory work is crucial for exposing the underlying structural components (like original floorboards and joists) to assess their condition, identify areas needing reinforcement, and create a clean base for new subfloor installation.
