As part of a renovation of our kitchen we had new flooring fitted last year. We bought vinyl from a large store and after months of delay it was delivered. Our builder fitted the vinyl over a new screed. It is quite light in colour and after a few month it began to darken in places. We contacted the seller about cleaning but it seems for vinyl soapy water is best. Eventually we sent photographs to the seller and they offered to replace the vinyl. We’re not sure this is wise as a replacement might develop the same dark patches. The seller sent a fitter of their own to meaesure up and price for fitting new vinyl. When he visited he suggested it was usual for vinyl to start to fade (or whatever) after maybe six months. This Is of course ridiculous unless there’s a serious fault. We now have seller estimates for fitting replacement vinyl. However, we assumed the the seller would make good all of our costs - I.e. fitting and new vinyl - but they seem to be saying they’ll cover half of the fitting costs as a goodwill gesture. We’d like to know what we can reasonably insist on. We won’t be using their vinyl or their fitting service as we have lost confidence and would like a refund of both vinyl and fitting costs in full. We might ask for compensation fit the inconvenience we’ve had but we’ve not decided yet. I should say the seller is a reputable firm that has in the past year seen it’s cudtomer service and after sales collapse into chaos. Thanks.
