Spongy Floor

My 2007 FOUR WINDS31F has a spongy floor .Its the hall way between the bedroom and kitchen.I never had any leaks that I know of.I would like to fix this myself but am wary about cutting thru any wires or structural supports.Thanks

My spongy floor was a result of a multi year, slight leak, behind the outside shower panel. Only found it while pulling it out, to stuff accumulator tank in behind it.

Previous owner put laminate floor over area. It's ok for now.

I had a spongy floor in a section as well.
Crawled underneath and cut the membrane to see how wet...

The thin plywood that sandwiches the insulation was rotten.

Had to cut out the damage and repair...fortunately I was able install brackets and put in a new floor in that section.
