Mold in chipboard flooring need replaced?

[CHRISJVC1]

Hi, I have discovered under my bath has had a slight leak and the flooring underneath is black with mold. I know chip board is absorbant so will I need to replace the floor? thanks

 

[JohnD]

yes

preferably with WBP ply.

While you have it up inspect the joists for damage.

ok wow so Im going to have to get bath removed. Wonder if this is an inscurance job

 

[JohnD]

nope.

 

[CHRISJVC1]

so there is no way of just cleaning up the mold and sealing the area?

 

[JohnD]

chipboard is rubbish, and worse rubbish once it's been wet.

Before doing that, how big a leak and for how long?--- check how wet the cr**board actually is and what condition it is in.
Try cleaning it over with strong bleach.
Costs nothing before accepting that something more is needed.

not sure how long its been leaking, probably about 6 -9months. covers an area of about 5 square feet. board is not soggy just covered in black mold but wooden frame for bath is also damp
