Entry Door Replacement: Steel vs. Fiberglass Doors
Replacing your front entry door can be a smart investment for your home. Studies show that a new entry door can recoup over 90% of its cost at resale, making it one of the best home improvement projects for return on investment.
Beyond its financial benefits, the entry door is often the first thing people notice about a house. It sets the tone for the entire home, acting as a “welcome” sign for guests and neighbors. A worn-out door can make a home feel neglected, while a stylish, well-maintained door enhances curb appeal and leaves a positive impression.
Homeowners who replace their entry doors often report additional benefits. A new door can improve energy efficiency, reduce outside noise, and increase security. It’s more than just a design upgrade—it’s a functional improvement that makes your home more comfortable and secure.
Among the entry doors, there are two major modern replacement door options on the market.
Steel Doors, and Fiberglass doors.
Let’s dig into what they are, and what makes them unique.
| Feature | Steel Doors | Fiberglass Doors |
|---|---|---|
| Security | High | Moderate |
| Energy Efficiency | Good (with foam core) | Excellent |
| Durability | Prone to scratches/rust | Highly durable |
| Cost | $500-$1,300 | $1,000-$5,000 |
| Aesthetic Options | Limited | Wide variety |
Steel Entry Doors
Specifications:
Made of specialized steel, most premium steel doors are constructed of 24-gauge steel, and coated in alloy materials like zinc, to resist scratching, and withstand the weather. Contrary to popular belief, most residential steel entry doors are not made of solid steel, but rather a 1/40th inch thick “steel wrap” around a foam core. This allows the door to be light enough to move and use, yet strong enough for the benefits of a metal door. The insulative core adds energy efficiency to the door, helping block heat and cooling loss, and saving on energy bills.
Weight: A standard size 80” x 36” door weighs about 60-100 lbs,. They are typically lighter compared with solid wood core doors.
Prices: Average, $500-$1,300 for premium quality models
Pros of steel entry doors:
- Tough and secure
- Energy efficient
- Affordable replacement option
- Has the highest return-on-investment, compared with premium fiberglass
Cons of steel entry doors:
- Virtually impossible to customize on-site
- Can get hot in the sun, including some possible fading
- Can scratch or dent
- Scratches can rust if exposed to moisture over time
Fiberglass Entry doors
Specifications:
Using the same material that is used for the body casting of airplanes, and lightweight sportscars, fiberglass entry doors include lightweight benefits, with long-lasting looks.
Fiberglass doors are NOT PLASTIC DOORS. Rather, they use glass fibers, which have the benefit of insulation, but sealed, for weather resistance. Like steel doors, the fiberglass skins wrap around a foam core, to provide insulation against energy-loss, while making it lightweight. Lower-end fiberglass doors which are found in most big-box stores, actually have a different construction method, with thinner skins, that can crack over time. Standard to high-quality premium fiberglass doors, which are usually available through custom door installers, are usually fully encapsulated, and thicker in the skin, which allows the manufacturer to offer lifetime warranties.
Weights: 50-100 lbs typically, for an 80 inch by 36 inch door. Often can be lighter weight than premium steel doors.
Prices: $1,000 - $5,000 for most premium quality doors
This is a newer product on the market, becoming popular within the past 15 years. 3 Yet, they have some of the highest benefits, especially for high-efficiency, and longest-lasting use.
Pros of fiberglass entry doors :
- Can be textured to look like real wood
- Endures temperature extremes better than steel, as it expands and contracts with hot and cold weather, without compromising the structure and energy efficiency
- Due to the weight being light, it may have the least opening noise, because of less tensile weight on the hinges
- Often have lifetime warranties, due to their long-lasting nature
- Excellent sound resistance
Cons of fiberglass entry doors:
- More expensive than other entry door options
- Not as secure as steel doors
- Skin may crack from extreme impact
Security Features: Steel vs. Fiberglass
Both steel and fiberglass doors offer significant security advantages compared to traditional wood doors, but there are key differences that may influence your choice. Below are the security features of each type:
Steel Doors
Material Strength:
Steel doors are inherently strong and resistant to forced entry. Their metal construction makes them an excellent choice for homeowners prioritizing security.
- Steel doors can withstand significant impact, making them difficult to break or kick in.
- Even though most residential steel doors are not solid steel, the steel skin provides a tough barrier against intrusion.
Reinforced Frames:
Security is not just about the door itself but also the frame. Steel doors are often paired with reinforced steel or metal frames, which add an extra layer of protection against prying or forced entry.
Lock Compatibility:
Steel doors are compatible with high-security locking mechanisms, such as:
- Deadbolts
- Multipoint locks
- Smart locks with reinforced strike plates
These locks can be installed securely without compromising the integrity of the door.
Fire Resistance:
Many steel doors are fire-rated, providing additional safety in case of emergencies. This feature makes them a secure option for both entryways and garage doors.
Fiberglass Doors
Reinforced Core:
High-quality fiberglass doors come with a reinforced foam or composite core, which adds strength and durability. While not as strong as steel, they are still resistant to forced entry.
Impact Resistance:
Fiberglass doors are designed to endure moderate impacts without cracking. Some premium fiberglass doors are reinforced with additional materials, such as steel plates or composite layers, to enhance their security.
Lock Compatibility:
Like steel doors, fiberglass doors support advanced locking systems, including:
- Multipoint locks
- Smart locks
- Reinforced strike plates
However, the strength of the lock depends on the door's internal reinforcements and the quality of the frame.
Shatterproof Glass Inserts:
Many fiberglass doors come with decorative glass inserts. To maintain security, these inserts are often made from shatterproof or tempered glass, preventing easy break-ins.
How to choose:
The type of replacement door you choose depends on your neighborhood and the style you want for your home. Both steel and fiberglass entry doors offer superior durability and security compared to most wood doors, especially hollow ones.
If you prefer the classic wood-grain look, fiberglass doors are an excellent choice. They closely mimic the appearance of traditional wood but without issues like warping, fading, or energy loss. Fiberglass doors also come in smooth textures if you’re not looking for a wood-grain finish. They are long-lasting and require minimal maintenance, making them a popular option for homeowners.
For those prioritizing security and toughness, steel doors are a solid choice. They are more affordable than fiberglass doors and offer excellent value for money. Steel doors also provide one of the best returns on investment, with most of the cost recouped at resale.
When replacing your entry door, you have two main options for installation: big box stores or specialized door replacement companies.
Big box stores offer convenience and a wide range of products. However, door replacement companies typically focus on premium-quality models and provide personalized service. They can guide you in choosing the right door material based on your home’s style, neighborhood, and specific needs. These companies also often include follow-up services, ensuring a smoother installation process and long-term satisfaction.
Choosing the right installer is just as important as selecting the door itself. A well-installed, high-quality entry door can enhance your home’s appearance, improve functionality, and provide lasting benefits for years to come.
Entry Doors in Toronto: What to Consider
Toronto’s diverse climate, with hot summers and freezing winters, makes durability and insulation key factors when choosing an entry door. Steel doors are excellent for security and affordability, while fiberglass doors offer superior insulation and resistance to extreme weather. Both options can handle Toronto’s seasonal changes, but fiberglass doors are often preferred for their energy efficiency and low maintenance in harsh conditions.
