Rot strands on concrete floor??

[TheOrk]

Not sure of anyone can help.

I've just discovered that a patch of skirting board in the corner of our living room is completely rotten.

This is beneath a window where we had damp proof work done 4 years with new skirting board as well as some of the adjoining skirting board against an internal wall.

I'm thinking it might be missing pointing/seal gone on the window outside, but lifting the carpet/underlay is a load of blackish strands on the concrete floor.

Could this be rot strands or just adhesive (it's sticky) when the underlay was laid. Pictures attached / it brushes off fairly easily in places.

Cheers for any thoughts.

Looks like spray adhesive

Could be Fungi from the wet rot that you have found.

Cheers for the replies.

In terms of identifying the cause of the rotten skirting - the floor seems dry so if it is a leak from window I assume that might become evident now I have a big whole on the skirting next time it rains??

Why not remove that length of skirting, & then post pics of the back of that piece of rotting skirting, the wall behind the skirting, & pics of the outside of the wall and window?

The two pics you've posted are a bit fuzzy?
