The cost to replace a front door with sidelights is usually higher than the cost of replacing a standard front door, but the final price depends on much more than the door itself. Whether you’re replacing a single sidelight or a full double-sidelight entry system, the biggest factors are the door material, the condition of the existing frame, and how much installation work is required.
We’ll break down average price ranges, compare common door materials and sidelight configurations, and explain when replacing the entire entry system makes more sense than replacing only the door.

What Affects the Cost to Replace a Front Door with Sidelights?
When estimating the cost to replace a front door with sidelights, the final price depends on much more than the door itself. Your choice of material, the number of sidelights, glass options, and the amount of installation work all play a role. Across Canada, homeowners typically pay between $3,200 and $10,000+ to replace a front door with sidelights, including professional installation. The final cost depends on the material, entry system design, glass options, and whether structural modifications are required.
Average Installed Cost by Door Material and Sidelight Configuration
The table below shows typical installed price ranges for common front door systems with sidelights in Canada.
| Material | Door + 1 Sidelight | Door + 2 Sidelights |
|---|---|---|
| Steel | $3,200–$5,000 | $4,500–$6,500 |
| Fiberglass | $4,500–$8,500 | $5,800–$10,500 |
| Solid Wood | $6,000–$10,000+ | $8,000–$14,000+ |
These are typical installed price ranges for Canada. Actual costs vary based on door size, glass options, hardware, custom designs, structural modifications, and local labor rates

Key Factors That Affect the Total Cost
1. Door Material
Door material is one of the biggest factors affecting the cost to replace a front door with sidelights. Steel systems generally cost the least, while fiberglass and solid wood increase the overall investment because of higher material and manufacturing costs.
Steel is generally the most affordable option. It offers excellent security, good insulation, and requires very little maintenance, although it can dent if subjected to heavy impact.
For many Canadian homeowners, fiberglass doors offers the best balance between appearance, durability, and maintenance. It resists moisture, handles seasonal temperature swings well, and can closely replicate the look of real wood.
Solid wood doors provide a premium appearance and can be customized in many styles, but they come with the highest purchase price and require regular maintenance to protect them from moisture and seasonal movement.

2. Sidelight Configuration
The number and style of sidelights also influence the cost to replace a front door. Adding a second sidelight increases both material and installation costs, but it also creates a wider entrance and brings more natural light into the home.
Not all sidelights cost the same. Standard clear-glass sidelights are usually the most economical option, while decorative designs, divided lites, custom shapes, or matching panel details increase both manufacturing and installation costs.
3. Glass Options and Energy Efficiency
Glass selection affects both appearance and performance.
Standard clear glass is often the most affordable option. Decorative, frosted, textured, or privacy glass increases the overall price, while premium decorative inserts can add $300 to $1,200 or more per sidelight.
Many modern exterior doors are available with Low-E coated, argon-filled glass, which improves energy efficiency, reduces heat transfer, and helps minimize condensation during Canadian winters.
4. Installation Requirements
Installation costs vary depending on the condition of the existing opening and the scope of the project.
A full-frame replacement—which includes replacing the frame, jambs, interior casing, and exterior trim—typically costs 20% to 30% more than replacing only the door slab. However, it also provides a better seal, improved insulation, and allows hidden issues around the opening to be repaired.
If you’re converting a standard front door into a wider entry with sidelights, the project becomes more involved. Expanding the opening may require structural framing, header modifications, exterior finishing, and relocating nearby electrical switches or trim, which can add $1,000 to $2,500 or more to the overall project cost.
Should You Replace Just the Door or the Entire Entry System?
If you’re trying to reduce the cost to replace a front door with sidelights, you may wonder whether replacing only the door is enough. In some situations it is—but in others replacing the complete entry system is the better long-term investment.
The decision comes down to the condition of the existing frame, the sidelights, and whether you’re simply replacing a worn door or updating the entire entrance.
Replacing Only the Door
If the existing frame and sidelights are in excellent condition, replacing only the door may be possible. This option can reduce material and labor costs while giving your entry a refreshed appearance.
A replacement door must fit the existing frame precisely. Even small differences in size, hinge locations, or door thickness can create installation problems.
If the existing frame is out of square or has shifted over time, replacing only the door may not deliver the results you’re expecting.
Replacing the Entire Entry System
If the frame is damaged, outdated, poorly insulated, or you’re changing the overall design, replacing the complete entry system is often the better investment.
A new door, frame, and sidelights are designed to work together, which can improve energy efficiency, weather sealing, security, and overall appearance.
Replacing the entire entry system costs more upfront, but it eliminates compatibility issues between old and new components while creating a cleaner, more consistent finished look.
How to Know Which Option Is Right
A professional assessment is usually the easiest way to determine whether the existing frame and sidelights can be reused.
Older homes often hide issues such as moisture damage, frame movement, or poor insulation that aren’t visible until the old door is removed. That’s why many suppliers recommend evaluating the entire entry system before ordering a replacement door. Organizations such as Fenestration Canada also emphasize the importance of proper installation and weather-resistant building practices for long-term performance.
What’s Included in the Total Replacement Cost?
When comparing the cost to replace a front door with sidelights, it’s important to understand exactly what the quote includes.
Not every supplier includes the same products and services, so two quotes with similar prices can cover very different scopes of work.
A typical replacement quote may include:
Door and sidelights
The cost of the new entry system, including the door slab, sidelights, glass, and frame if you’re replacing the entire unit.
Hardware
Handles, locks, hinges, weatherstripping, and other accessories may be included or priced separately depending on the supplier.
Installation
Labor usually covers removing the existing door, preparing the opening, installing the new system, insulating around the frame, and completing the final adjustments.
Finishing work
Depending on the project, trim, casing, painting, staining, or minor repairs around the opening may also be included.
Because every supplier structures their quotes differently, it’s worth asking exactly what’s included before comparing prices.
How to Save Money on a Front Door Replacement with Sidelights
Replacing a front door with sidelights is a significant investment, but there are ways to keep costs under control without compromising quality or long-term performance.
Here are a few practical ways homeowners can reduce the overall project cost:
Choose the Right Material
Selecting the right material for your home and budget can have a significant impact on the total cost. Steel doors are generally the most affordable, while fiberglass offers a balance between durability, energy efficiency, and maintenance. Wood doors typically cost more but may be worth considering for homeowners prioritizing a traditional appearance or custom design.
Replace the Door Before Major Damage Occurs
Waiting too long can increase the cost of the project. If moisture damages the frame or surrounding structure, additional repairs may be needed before the new door can be installed.
Replacing an aging door before those problems develop can help avoid unnecessary repair costs.
Compare Detailed Quotes
When requesting estimates, compare more than the total price. Make sure each quote includes similar products, installation services, warranty coverage, and hardware so you’re making a fair comparison. Working with an experienced door supplier in Vancouver can also make it easier to understand what’s included in each quote and which options best fit your home.
Invest in Quality Installation
Choosing an experienced installer can help prevent costly problems such as drafts, water leaks, and alignment issues while extending the life of your new door.
What to Remember Before Replacing Your Front Door
The cost to replace a front door with sidelights is higher than replacing a standard entry door, but it can significantly improve curb appeal, natural light, energy efficiency, and security. Understanding what affects pricing makes it easier to compare quotes and choose the right entry system for your home.
If you’re planning a replacement, take time to compare complete quotes rather than focusing only on the initial price. The right door system should provide long-term performance, not just a lower upfront cost.
