Yes! Most of our panels do have color-matching caulk, which is typically available for purchase at your local Home Depot or Lowes. To help find a retail location near you, feel free to use our where to buy, locator. You can also purchase color matching caulk directly from our website.
Any place GenStone is carried, they should also sell the caulk. Should the color you choose not have a color matching caulk, we recommend purchasing a clear paintable caulk from your local hardware store and painting with one of our color-matched paint.
