Worktop Mitre

[bigpapanoodle]

I wish to change the existing setup of a free-standing cooker with worktops either side to an inset hob with single oven beneath worktop. We have a small galley kitchen. Please see attached file.

I am being told that I will need to replace ALL the worktops in the kitchen as it is not possible to create a new male mitre joint against an existing female joint. Is there a practical reason for this or is my local kitchen showroom trying to sell me a new kitchen.

The practical reason is that once a mitre joint is broken (they are glued together) you can not join a new piece up to it perfectly. And seeing as the joints are the areas most likely to get damaged from water ingress then they do need to be perfect to stand any chance of lasting

Also the jig that was used to make the inital joint may not be the same jig that the new worktop fitter has, so again they won't go together well, if at all.

There are exceptions to the rule and in some cases it is possible to do what you want, but it is a lot of messing around with no guarantee it will work. So most fitters won't want to undertake what you are suggesting as the risks are too high or you end up with a bodge job

We take worktops off when we do insurance work. It can be done as can replacing one length. You do not need an off the shelf jig for masons mitres, you can make a template from old worktop.
