Asking for a friend:

What's the best way to install the click-type laminate flooring along
the face of a 10 foot wide brick faced hearth? It's being installed
long side against the hearth.

He's working on a paper template of the grout joints, etc, but isn't
sure he'll be able to cut the laminate precisely enough for a good
fit. I mentioned caulk, but he said there's red brick, grey brick,
mortar and brown flooring. Not sure if any given color of caulk would
work.

He consider a transition piece as molding, but there would still be
gaps behind that so he's not sure he'd like the look.

Any tips from those that have done it before?

Thanks!
