Keystone Warranty

Keystone Patio will stand behind the products we manufacture for as long as you own your home. We will warranty Keystone Patio products against manufacturing defects and replace damaged products free of charge.

The replacement product will be supplied, but the warranty does not cover delivery, installation and labor. We cannot guarantee color matching to previously existing materials. The Keystone warranty does not include splitting, chipping, cracking or other damage that may be caused by impact, abrasion, overloading or improper installation.

For the warranty to be approved, a proof of purchase is required at the time of warranty request.
