Are you considering getting a door replacement but wondering how long fiberglass doors last?

If your fiberglass doors are professionally installed and you maintain them well, they can last up to 20 years. However, there are other factors to consider that can affect the lifespan of your fiberglass door.

How Long Do Fiberglass Doors Last in Kentucky?

Kentucky has hot, humid summers and cold winters, which can take a toll on your front door. If you don’t have an awning, your front door is exposed to the elements, making it deteriorate faster.

Fiberglass doors inside your home can also sustain wear and tear but will last longer than exterior doors.

Material Quality

High-quality fiberglass doors will last longer because they are designed to withstand the volatile Kentucky weather. At Kentucky Home Exteriors, we are factory-trained Provia dealers and use their industry-leading fiberglass doors for our door replacements.


Fiberglass doors can last decades under the right conditions. Fiberglass is known for its longevity and resistance to warping, cracking, and rotting. It also resists extreme temperatures and temperature fluctuations.

High-quality fiberglass doors also have UV-resistant finishes that protect them from premature fading. However, extreme conditions, such as prolonged exposure to harsh sunlight or severe weather events, can affect the door over time.


Regularly inspecting and performing routine maintenance on your fiberglass door can add to its lifespan. Check the frame, hinges, weatherstripping, and caulking to keep your door functioning effectively and looking good.

Tips For Making Fiberglass Doors Last Longer


  • Clean the door regularly using a mild detergent and water. Use a soft sponge or cloth to avoid scratching the surface. Skip the abrasive cleaners or scouring pads. 
  • After cleaning, rinse the door thoroughly with clean water to remove any soap residue. Make sure to also rinse the door frame and hardware. 
  • If the door has glass inserts, clean them with a glass cleaner. Don’t let the cleaning solution come into contact with the door because it can damage the finish.


  • Inspect the door for any signs of damage, such as cracks, scratches, or dents. 
  • Check the seals and weatherstripping around the door for wear or damage. Replace any damaged weatherstripping to maintain the door’s energy efficiency.
  • Inspect hinges, handles, locks, and any other hardware regularly. Tighten loose screws and lubricate moving parts if necessary.


  • If the door is exposed to direct sunlight, consider using a UV-resistant coating or sealant to protect it from UV damage and potential fading. 
  • Avoid harsh chemicals, solvents, or abrasive cleaners on the door, as they can damage the finish. Stick to mild, non-abrasive cleaning solutions.

Seasonal Maintenance

  • In areas prone to freezing temperatures, ensure the door is properly sealed to prevent drafts. Consider using weatherstripping designed for cold weather. 
  • During hot weather, avoid exposing the door to prolonged direct sunlight, as extreme heat can affect the finish. Consider using window coverings or shades to protect the door.

A Professional Installation is Key

While fiberglass doors are known for their durability and low maintenance, how they are installed can significantly impact their performance and lifespan.

A professionally installed fiberglass door won’t experience structural issues like warping, twisting, or sagging. Fiberglass doors are durable, but mishandling during installation can lead to scratches, dents, or other damage. A professional company will handle the door with care from start to finish.
