The pillar kits do not come with trim pieces, but GenStone does have accessories that are available to purchase separately. GenStone offers a peaked-style and a flat-style cap to finish off the top of pillars and columns. Other than for aesthetic purposes, the caps also help to shed water. For the base, you can either cut out the center of a cap so that your piece maintains its paired fit to the kit you are using, or custom cut pieces of ledger to fit around the desired area. The latter option will require a bit more carpentry skill.
