Corian countertops can crack or burn or become scratched over time.
Corian is a resilient product. It can be repaired if there is available color match material to the original countertops. As demonstrated in the pictures below.
The surface can also be resanded to a standard matte satin finish in most cases bringing the countertop back to its original lustre.
We offer these services and would gladly discuss any options you may have with your existing countertops.
