25-Year Limited Warranty

CraftStone™ wall products carry a 25-year limited warranty when used on structures that conform to local building codes and installed according to the manufacturer’s instruction. Warranty is limited to replacement of defective materials only. Damages resulting from building settlement, wall movement, force contact, contact with chemicals or paint, discoloration due to air borne contamination, staining or oxidation, will not be covered under the warranty. Warranty is non-transferable and is only limited to the original purchaser.

Water Repellent

CraftStone™ wall products feature the addition of silicone-based water repellent that greatly enhances the stone’s performance in humid climate.Water Repellent is mixed with the composite material during manufacturing, thus providing a more lasting effect then spray, brush or paint method.

Noncombustible

CraftStone™ products show zero flame spread and zero smoke development.
