First I looked at how the gasket was attached to the door. Seeing it was simple screws holding the gasket in place around the door, I decided I could do this myself. I did have to spend time warming up the gasket to remove warps from the packaging used to ship. I laid it out on beach towels in the den, straightened by hand, and then used a hair dryer to warm up sections and reformed them by hand. There were 3 places that needed a small piece of wood laid on top, with a weight placed on the wood, to fully reform the warps.
