Installation Note: Properly align the pieces up before installing as each piece goes in a specific spot. You can find DIY installation videos on social media sites, otherwise we recommend professional installation. We do not cover installation error, including adhesion issues caused by dirty surface or installing in cold weather, misalignment issues, etc. Cleaning pillars make sure you use non-scratch cloth only. If you mess up a piece during installation, we can sell you a replacement piece. If you have any questions about installation, please ask us before installing.
