Environmental Stoneworks is making its ClipStone mortarless stone veneer system more widely available. The manufactured stone pieces install one at a time, but go up quickly thanks to a clever, self-spacing metal clip on the back of each stone. The clip maintains a 5/8-inch gap between the veneer and the substrate, allowing water to move to weep holes in the starter channel. With no mortar or mason necessary, ClipStone is relatively easy to install, even for siding contractors who don’t usually work with stone. Pricing ranges from $10 to $12 per square foot. myclipstone.com
