Anyone want to do a paid visit and offer advice

[Keith Gypps]

Hi all, Both my wife and I are at our wits end. we have had circa 50 sqr mtrs of large tiles laid 600 x 600mm and 1200 x 600mm All tiles laid on top of a durabase membrane laid on top of underfloor heating trays. When starting the job the tiler stated that there was some movement with the underfloor heating trays but he was "pouring adhesive down" to rectify this. Within days the tiles started popping and clicking when walking on and despite repeated applications the grout keeps coming out. We have been and continue to try to be the epitome of friendliness and kindness with the tiler whom agreed that he would come back and replace the grouting with an epoxy resin grout instead of the standard grout used, he was meant to do a few tiles to start with to see if that rectified the issue. He contacted me last night to say that he had been "thrown under a bus" by the plumbers that it wasn't his fault and we should now make a claim against the plumbers insurance, ive asked him to come and do just a few tiles to see if it will work with epoxy resin so i can make an informed decision , pay him to do it (We just want an end to it) or pay someone else, however i doubt anyone would want to do it. I have been advised by my house insurance legal helpline to try arbitration and if that's refused to sue both the plumbers and the tiler. We really aren't that sort and just want to resolve as amicably as possible, but to move forward i need an assessment of the current job to try and get some sort of evidence as to what's wrong so i can get quotes to rectify it. Anyone willing to do this (Cambridge area SG8) or know a professional organisation i can contact or has been down this route before. Thanks for reading
