Pros of Fiberglass Doors


Fiberglass doors are incredibly durable and can withstand harsh weather conditions, such as extreme heat and cold, rain, and wind. They are also resistant to dents, scratches, and other types of damage, making them a long-lasting and reliable option.

Energy Efficiency

Fiberglass doors have excellent insulation properties, which means they can help keep your home warm in the winter and cool in the summer. This can lead to lower energy bills and a more comfortable living environment.


Fiberglass doors are more secure than wood doors. They are made with a sturdy frame and have multiple locking points, making them difficult for intruders to break through.

Low Maintenance

Fiberglass doors require very little maintenance compared to other materials, such as wood. They don't need to be painted or stained regularly, and they won't rot or warp like wood can over time. This can save you time and money in the long run.


Fiberglass doors come in a wide range of styles, colors, and finishes, making it easy to find a door that matches your home's aesthetic. Fiberglass doors can be designed to mimic the look and feel of wood, without the drawbacks of wood doors. They can also be customized to fit your specific needs, such as adding a window or decorative glass.

Cons of Fiberglass Doors


Fiberglass doors can be more expensive than other materials, such as steel and wood. However, the durability and energy efficiency of fiberglass may make up for the initial cost in the long run.

Limited Color Options

While fiberglass doors do come in a wide range of colors and finishes, they are still more limited compared to other materials, such as wood. If you have a specific color in mind, you may have a harder time finding a fiberglass door to match. If you're looking for a truly unique door, wood may be a better option.


Installing a fiberglass exterior door can be more difficult than other materials, such as steel, due to its weight and size. This can lead to higher installation costs if you need to hire a professional. If you do decide to hire someone, it's important to hire a professional door installer to ensure that the door is installed correctly and securely.

Expansion and Contraction

Fiberglass doors can expand and contract with changes in temperature and humidity, which can cause the door to warp over time.

Potential for Cracking

While fiberglass exterior doors are durable, they are not completely immune to damage. In some cases, fiberglass doors can crack if they are hit hard enough, such as by a heavy object or severe weather.

Environmental Impact

Fiberglass is a petroleum-based product, which means that it has a higher environmental impact than wood. If you're looking for an eco-friendly option, wood may be a better choice.
