    Hi we have been in our home 11 years. Within a year of being in tiles started cracking randomly on the floor but also the corners of the rooms started falling in to the point you could put your hand in under the skirting board. It seems.screed was not laid properly and/or not let dry. Floors are totally uneven. Want to replace the tiles and put a vinyl/laminate floor over them but a fitter has been out to say that floors are so uneven that you could never get a levelling compound level.to lay the floor. Mentioned lifting tiles and screed and relaying screed. Nightmare stuff. Anyone ever heard of a problem like this and how could it be fixed

    Worst case scenario the screed will come up with the tiles. Just get a new sand cement screed laid.

    Thanks but that is what we are afraid will need to happen. New screed. Move out of house for 2 months to let it dry, etc.

    It may not need a new subfloor just a smoothing compound Lay the floor the next day What's the panic

    Excuse my ignorance but can you expand? We took up ten tiles last year and it was an absolute nightmare for the tiler. They were originally laid badly. The tiles cover our whole downstairs so from front door to back
    So if we took them all up and then lay a smoothing compound to try and negate the bad screed- is that what you mean? If we did that how long would compound need to dry for?

    Tiles will all need to come up anyway so prepare for atleast 2 - 3 days of disruption whilst the prep is being sorted.

    By sounds of it you would need 2 layers of screed (1 base & 1 finish coat)

    It’s cheaper to re screed than latex and you can get rapid drying screeds that will set in 2-3 days.
    This is totally worse case and you may find you just need to strengthen the weak subfloor and put a levelling compound over the top to level it out. Either way you won’t know until you lift it all out

    I've attached some pictures. Mostly of the corners of the rooms where the floor seems to be falling in. The floor is completely uneven

    Like merit says you'll need to get them up and access it from there whether you need a good base laying before the finishing screed.

    In my experience that has always been the case. If they were solid enough then there would be an option of going over them with a fresh screed but from you have said and from what we can see they will need uplifting before anything else

    Looks like you’ve got subsidence that’s so bad!
