Why is it so important to have annual maintenance done on the door?
Since wood is a natural resource, it does change over time, and with exposure to the environment. This is especially true if there is not a over-hang, or portico, to protect the wood door from environmental exposure. For example, if you choose to have a door with a darker stain, over time that stain will fade from prolonged exposure to the sun. In order to prevent fading, and other possible changes, it is best to book a annual maintenance.
