Joining square edged worktops at right angles

There are a couple of different joints when fitting kitchen worktops, in my experience, it's always best to use the bolts regardless of the join you use, being that a mitre or a mason joint (where the 2 edges are butted Up to eachother)

We use the worktop joining bolts on all our joints. We would also seal the joint depending on the worktop meterial. With the correct tool set it is a straight forward task to fit the bolts.

The only joint I have used is the masons mitre joint with a half Inch router and new router bit each time on laminate worktops. Also with the 3 securing bolts. Never had any problems.

The question is a bit vague to be honest. Apart from the square edge aspect, it doesn’t say what type of worktop it is and from which material it is made. The best way to join a square edge laminated WT is to remove the laminate, the width of the butted worktop from the longer length, butt up, glue and bolt together. There are other methods, but that’s the commonly used one. Are you sure he’s not biscuit jointed it? That is invisible from the outside, as the jointing ‘biscuits’ are embedded in the edge of the WT. Obviously other methods are used, dependant on which material the WT is made from. Generally speaking, I have rarely seen them jointed without the aid of some kind of fixing, whether it be clamps, or biscuits.

Sounds like he’s taken the easy option. I always use the jointing bolts, it prevents any movement in the joint. It’s your discretion whether you pay him.

I would not use butt and scribe jig but square ends and use fixing bolts and maybe biscuits

I always trim Back the laminate to but the worktop on , biscuit the join and three bolts , plenty of colour fill
