Looking to join 2 Kitchen worktops together (straight join) 1 worktop is 4000mm x 700mm and the other is 600mm x 700mm I require a total worktop length of 4120mm. What type of joint do I need for best result and where is it best to cut the worktops to be secure. I have had an estimate for a mitre joint of £50.00 over the phone by a joiner from my local paper is this a good rate. Thanks in advance.
