Steel vs. Wood Exterior Doors: Major Things to Consider
Key Takeaways
- Both steel and wood exterior doors offer distinct benefits depending on your home’s design, climate, and lifestyle.
- Steel doors excel in security, insulation, and durability — ideal for Canadian winters.
- Wood doors deliver unmatched natural beauty and warmth, but need more care and upkeep.
- Installation, maintenance, and long-term performance should all factor into your decision.
- Always consult a trusted local expert to ensure your new entry door complements your home’s structure and energy goals.
Understanding the Basics: Steel vs. Wood Exterior Doors
When choosing between steel and wood exterior doors , it helps to understand how each material performs in Canadian conditions.
Steel doors are known for strength, security, and insulation. They’re built with a solid metal skin over an insulated core, which helps resist drafts and temperature changes. They don’t warp or crack, making them a practical choice for areas with extreme cold or moisture.
Wood doors offer natural warmth and a timeless look that many homeowners love. Each grain pattern is unique, and the material feels rich and inviting. However, wood reacts to humidity and needs regular sealing or refinishing to stay in good shape.
Both materials can enhance comfort and curb appeal — your choice simply depends on whether you prefer long-lasting ease or the timeless charm of natural wood.
Installation Requirements
Steel doors usually come pre-hung, meaning the door and frame arrive as a single unit. This design ensures a perfect fit, but it also leaves less room for on-site adjustments. Since steel doors are heavier, professional installers reinforce the surrounding frame to ensure lasting alignment and smooth operation.
A professional installer checks that the hinges are aligned, the frame is plumb, and all seals sit tight, preventing heat loss and air leaks.
High-quality weather-stripping and thermal breaks help steel doors deliver the insulation and comfort Canadian homeowners expect. These components reduce heat transfer, block drafts, and keep moisture from entering around the frame — critical for maintaining comfort during harsh Canadian winters.
Wood doors, meanwhile, demand a slightly different approach. They’re lighter and easier to handle, but sensitive to humidity changes. Before installation, wood doors need time to adjust to your home’s environment — this helps prevent future swelling or shrinking. Once installed, the perimeter seals, threshold, and jamb must be carefully adjusted to ensure even pressure and smooth operation.
— Tony Wong, Project Manager at Canadian Choice Windows & Doors , emphasizes:
“A professional installation isn’t just about hanging the door straight — it’s about sealing, insulating, and aligning every detail for lasting comfort. Even the best door won’t deliver its full comfort and efficiency if the frame isn’t perfectly aligned and sealed.”
A properly installed door system ensures not only smooth operation but also long-term energy efficiency, noise reduction, and weather protection — benefits that make professional installation well worth the investment.
Maintenance and Longevity
Maintenance is where these materials truly diverge.
- Steel doors resist warping and cracking but can dent if struck hard. A quick wipe and an occasional coat of protective paint keep steel doors looking new and rust-free for years.
- Wood doors offer natural beauty but need regular refinishing to stay protected from Canada’s changing weather — from bright summers to freezing winters.
Annual inspection for both types — checking seals, hinges, and finishes — ensures optimal performance and prevents costly repairs later.
Energy Efficiency and Insulation Performance
Energy performance plays a significant role in door selection, particularly for Canadian homeowners.
| Feature | Steel Doors | Wood Doors |
|---|---|---|
| Insulation | Foam-filled cores and thermal breaks deliver exceptional energy efficiency. | Natural insulator but less consistent; efficiency depends on thickness and sealing. |
| Weather Resistance | Excellent — minimal swelling or shrinking. | Vulnerable to humidity changes and warping without regular maintenance. |
| draftLOCK™ Compatibility | Works perfectly with modern weather-tight systems like Canadian Choice Windows & Doors draftLOCK™ technology. | May require added weather-stripping to match performance. |
— Helen Sin, Consumer Success Manager at Canadian Choice Windows & Doors, adds:
“Many homeowners are surprised by how much an insulated door improves comfort. A well-built steel door helps keep warmth inside and heating costs down — especially through Canadian winters.”
Aesthetic Versatility and Customization
For design-minded homeowners, both materials have evolved significantly.
Wood doors remain the gold standard for curb appeal — available in countless grains, stains, and carvings that complement traditional and contemporary façades alike.
Steel doors, on the other hand, now offer wood-grain finishes, decorative glass inserts, and panel styles that mimic authentic timber while providing superior insulation and security. This combination of modern performance and timeless design gives homeowners a door that looks great and works well year after year.
Security and Durability
In terms of strength and impact resistance, steel offers unmatched protection and reliability. A properly reinforced steel door, paired with multi-point locking systems, offers exceptional protection against forced entry.
Wood doors, particularly solid-core models, also provide reliable security but can weaken over time if not properly sealed or maintained.
| Feature | Steel Door | Wood Door |
|---|---|---|
| Security | Highly resistant to forced entry; compatible with multi-point locks. | Strong, but can weaken with age or moisture damage. |
| Durability | Dent-resistant coatings ensure longevity with minimal care. | With regular refinishing and sealing, a wood door can last for decades while maintaining its natural charm |
| Fire Resistance | Naturally, more fire-resistant. | Requires treatment for fire-rated performance. |
Environmental Considerations
Many homeowners today prioritize sustainability.
- Steel doors are 100% recyclable, and most Canadian-made models include a percentage of recycled steel.
- Wood doors, when sourced responsibly from FSC-certified forests, provide a renewable, biodegradable option.
Because steel lasts longer and needs less upkeep, it often leaves a smaller environmental footprint over its lifetime.
Cost Comparison
Initial costs vary by design, insulation level, and customization.
| Cost Factor | Steel Door | Wood Door |
|---|---|---|
| Average Price Range | Moderate – Higher for premium finishes | Moderate to High, especially for solid hardwood |
| Maintenance Costs | Low | High – requires refinishing and weatherproofing |
| Long-Term Value | Excellent durability, low upkeep | High aesthetic appeal but ongoing maintenance costs |
While wood adds character, steel often provides greater long-term value thanks to its durability, insulation, and minimal maintenance.
Which Door Is Right for Your Home?
Your choice depends on what you value most:
- Choose steel for security, energy efficiency, and low maintenance.
- Choose wood if you prioritize natural charm, customization, and timeless warmth.

Frequently Asked Questions
Are steel doors energy-efficient?
Yes. Modern steel doors feature insulated cores and tight weather-seals that outperform most wood models in heat retention and air-leak prevention.
Can wood doors handle Canadian winters?
They can — but only with consistent maintenance. Regular sealing and painting are key to preventing swelling, cracking, and moisture damage.
What’s the average lifespan of each door type?
Steel doors typically last 20–30 years with minimal maintenance, while high-quality wood doors can last just as long if properly cared for.
Can steel doors be painted or refinished?
Absolutely. Many modern steel doors come with paintable surfaces and factory coatings designed to resist chipping and fading.
