What is the best way to repair a detached under mount sink?

Our stainless steel under mount kitchen sink came detached from the quartz countertop. It had been mounted about a year ago using silicone only, though I see from an online search that mounting clips can also be epoxied on to ensure a stronger attachment (this wasn't done).
A local plumber reattached it using silicone and copper strapping screwed into the cabinetry, but we're a little concerned that the repair will not stand the test of time. It's also not the most neat looking solution - we had assumed that he would use clips.
Any suggestions for how this could be improved for the long term?
Thanks!

Hi there,
On all of our under-mount sink installations we use a High Quality Silicone and never had any issues to date. I would recommend this and have it propped up for 24 hours and that should do the trick. You will probably be able to remove the copper straps that were installed.

H Conor,
I agree with Dave. I have fixed a few and made sure the mating surfaces were as clean as possible. These sinks all took up all of the room in the cabinet where I would usually epoxy some mounting clips. I used 2 X 4 pieces under the sinks and across the hole in the counter. A couple of bar clamps through the drain holes and around the 2 X 4 s provided plenty of force to ensure the top quality silicone was tight and evenly distributed. 24 hours later and you could probably stand in the sink.
If your plumber took the time to clean everything well and used the copper straps to pull everything tight, you should be good to go. You could remove the straps and not worry about it.
