Crunchy Victorian tiles

[Clubster]

The crunching is only in the part where the floor warms first (so far). Flooding was over 18 months ago. Dehumidifier was on straight to dry out the lower floor

It can take 10 months to dry out with dehumidifier before you can tile on a flooded area and if the water got under the tiles after they were installed it will have released the bond.
Not your builders issue but you should contact your insurance company as it was obviously something that has come to light since loss adjusters report!

I'm quite amazed that you thought of that tj!
Almost certainly the cause, how come you didn't mention that in the first post ?

The flood was from the water softener and affected two rooms. Hallway and lounge. Their wasn't much water in the hallway, about an inch in the lounge.

Just realised the insurers don't know I had a flood 2yrs ago I never claimed for anything...

Where abouts in Surrey are you? Someone on here might be able to help

Weybridge.

Is the likely solution to pull up crunchy area, sort out substrate and re-lay tiles?

 

[Flintstone]

Yes that's probably the best thing
