Fiberglass that looks like wood

This front door makes a statement and has little to no maintenance. The great thing about a wood-look fiberglass door is getting all the benefits and beauty of a wood door without the maintenance. While wood doors can be beautiful you have to know what you're getting into. This door comes with a lifetime warranty and comes pre-stained from the factory to give a real wood look.
