Exterior vinyl doors are easy to maintain. Vinyl can be wiped clean with mild soap and water. Vinyl is not as susceptible to water damage and other decay as wood. Since vinyl is lighter in weight than metal or wood, a door can be hung using smaller hinges.
Vinyl doors have a lower cost than wooden or metal exterior doors. Vinyl doors can be purchased that very closely mimic the look and feel of more expensive and less durable wooden doors. Since vinyl doors do not absorb moisture like a wood door, they are less prone to warping and becoming hard to close and shut over time.
Vinyl doors come in a variety of colors and finishes that do not have to be redone like those on wooden doors, which have to be repainted or refinished regularly. Vinyl doors can be hung on a weaker framework than that required for a heavy steel or wood door. Exterior single doors are just one style of exterior vinyl door. Many homeowners choose vinyl doors with glass inserts for patio enclosures or balcony doors.
Wood doors are much harder to scrub clean than the smooth surface of vinyl. Wood doors often have to be repainted to ever look clean after they are a few years old. Metal doors can become scratched and may need to be painted with a thick paint to cover marks.
