DeMarco Collection offers a complete line of French Doors. Our Mahogany French doors are constructed with only the finest Honduras Mahogany available. Our Custom Mahogany French Doors can be glazed with the glass of your choice, though typically we furnish all custom mahogany French doors with either tempered Low E insulated glass or hurricane impact glass. Mahogany exterior doors are a logical choice amongst custom home builders, architects, and home owners alike for its inherent natural beauty. It is also a little known fact for some areas of the United States and the Caribbean, where there are problems with termites, that termites do not infest mahogany.
