Choosing the Perfect Door Replacement: Fiberglass or Metal

Table of Contents

When the time comes to replace a door, we want you to be informed of your options. It might be due to a deteriorated or outdated door to boost your home’s curb appeal or increase energy efficiency. Choosing the right material for your new door depends on your lifestyle and how you want it to meet your needs.

This article will discuss the pros and cons of two popular choices: fiberglass and metal doors.

Advantages of Fiberglass Door Replacements

  1. Durability: Fiberglass doors are impressively durable. They are designed to withstand harsh weather without warping, rotting, or rusting. This makes them an excellent choice for door replacements if longevity is your priority.

  2. Excellent Insulation: Another advantage of fiberglass doors is their superb insulation. These energy-efficient doors are excellent at stabilizing your home’s internal temperature. This keeps your home comfortable and can help reduce energy costs.

  3. Low-Maintenance: A significant advantage of fiberglass doors is their low maintenance requirement. Unlike other materials, fiberglass doesn’t require frequent repainting or staining. Regular cleaning is typically all that’s needed to maintain an attractive appearance.

Disadvantages of Fiberglass Door Replacements

  1. Potential for Damage: Despite their durability, fiberglass doors can crack under severe impact. This is a rare occurrence, but these cracks can be challenging to repair when it does happen. However, your fiberglass door can last many years with regular maintenance and care.

  2. Color Fading: Over time, the color of fiberglass doors can fade due to continuous exposure to UV rays. This may require repainting or restaining to restore their original look. Remember if your entry will be exposed to direct sunlight for most of the day.

  3. Quality Variation: Another disadvantage of fiberglass doors is the significant variation in their quality. Some are made with top-notch materials and craftsmanship, while others may need to meet the same standard.

Advantages of Metal Door Replacements

  1. Strength: One of the most significant selling points of metal doors is their strength. They offer excellent security and can withstand high impact, deterring potential intruders. If security is your main concern, a steel door might be your best choice.

  2. Cost-Effective: Metal doors are typically more affordable than fiberglass doors. They offer a budget-friendly option that doesn’t compromise on strength or durability. Consider a steel door if you want to replace your door without breaking the bank.

  3. Fire Resistance: Metal doors have the added advantage of being fire-resistant. This adds an extra layer of safety to your home. This feature, combined with their strength and durability, makes steel and metal doors a sound choice for many homeowners.

Disadvantages of Metal Door Replacements

  1. Poor Insulation: One downside of metal doors is that they aren’t as insulated as fiberglass. This could lead to higher energy costs. However, this can be mitigated by choosing one with an insulated core.

  2. Possible Dents and Scratches: While metal doors are strong, they can be susceptible to dents and scratches. Additionally, if the door’s finish gets damaged, rust can become a problem if the door isn’t correctly maintained. Despite these potential issues, many homeowners find that the strength and security of steel doors outweigh these drawbacks.

  3. Aesthetic Considerations: Metal doors often have a more industrial look, which may appeal to only some. They don’t offer the same warm, classic aesthetic as wood or the versatility in appearance offered by fiberglass doors. However, a metal door can still make a strong impression with the right design and finish. 

Choosing Your Door Replacement Material

There’s no one-size-fits-all answer when choosing between a fiberglass or metal door for your door replacement project. Your decision will depend on various factors, including your budget, home style, and personal preferences.

A fiberglass door might be your best bet if you value durability, insulation, and low maintenance. But, if strength, security, and cost-effectiveness are your top priorities, a metal door could be the right choice.

Remember that both types of doors have unique benefits, and either can be a great choice depending on your needs. To make the best decision, consider your home’s particular conditions and requirements, and weigh these against the pros and cons of each door type.
