Hi, we plastered a couple of rooms in a property 2 years ago and now the customer wants a refund or the hole job re skimming, we have been to look at the job and there's a couple of defects nothing major but he's going around with an led light shinning it up the wall purposely looking for defects, he has thretened us with legal advice, but apart from sorting the visible defects I don't see why I should have to re skim a job that was done 2 years ago and he also paid us straight away after comming home to check the work, I've done some research that says a defect period last for 12 months and we didn't sign a contract. Can anyone advise me on what to do next? Thanks
