LVT flooring issue

mikec27

Hi, 

I got Invictus LVT flooring fitted last year in my new extension - it was supplied and fitted by a local authorised dealer. 

They secured plywood boards to the chipboard sub floor and glued the LVT to the plywood. 

We’ve since noticed visible lines showing through at the points the plywood boards join (see photo) indicating the boards have become loose

The dealer has been inspect and has offered to remove some of the tiles to establish the cause- he has indicated that the cause could be either due to the plywood not being attached properly to the sub-floor or issues/movements in the sub-floor itself. I did ask him if the fitters would have checked the suitability of the sub-floor and he confirmed they would have. His point seems to be that the sub-floor might have moved since (e.g. due to subsidence) 

If it is determined that this was due to issues with their installation then he will replace it all at no cost. If, however, it is deemed to be issues with the sub-floor he said that I would be liable for the cost of the work 

It’s strikes me that it is definitely not in the dealer’s financial interest to replace it all and might be using the risk of ‘me being liable to pay’ to deter from taking it further. I’m also concerned that he is not ‘independent’ given its in his interests to argue the problem is in the sun-floor not the installation 

I feel like I’m over a barrel. Any advice on what I can do and what my rights are? I really need a credible independent view. I’ve tried contacting the LVT supplier themselves but not sure what they can really do. 

Thanks

I'd check what grade of ply they've used. There is a standard they should use BS 8203:2017 - many do not.

I’d be inclined to think they haven’t applied a skim coat over the joins and this has showed through over time as it’s been walked on perhaps. I’d just watch them as they take it up and see what they have, or haven’t done.
