Advice needed, floor sinking. - Tile Advice

[J K Tiling Cornwall]

I have a customer who has an original tiled Victorian hallway. In geometric quarry tiles. There is a section that has recently dropped and flexes when walked on. The two rooms that run next to the hallway have suspended timber floors. The section that has sunk sounds and feels like it could be on wood. Has anyone had any experience of this type of tile being installed over wood? The rest of the floor is solid and feels like concrete underfoot. Was hoping to try and lift some floor boards to investigate further. Any help would be great.

Could be joists onto sleeper walls. Might be loose joist on the bricks.

Thanks Dave. Once I get the time to go back I'm going to try and get under the floor, hopefully might be a case of propping up anything that has dropped and repairing any loose tiles. Will post the outcome on here.

You might have timber decay issues, as their is some evidence of staining around nails in the timber flooring. In any case you will need to get under the floor to inspect.

By the way, the dark staining around the nail heads, is quite often the result of sub-floor condensation.

Thanks for that info. They want to salvage the floor as it is original. Depending on what I discover underneath. Hopefully nothing too major, fingers crossed. But will post the outcome. 👍
