Understanding the Investment: What You’ll Pay for New French Doors
The cost to replace exterior french doors typically ranges from $1,300 to $5,500 for a standard installation, with most Chicago-area homeowners spending around $3,500 to $4,500. Here’s what drives that price:
- Material choice: Vinyl ($500-$2,000) | Fiberglass ($850-$4,500) | Steel ($700-$3,000) | Wood ($300-$2,000) | Clad-wood ($2,500-$5,000)
- Glass type: Double-pane ($700-$3,000) | Triple-pane ($800-$5,000)
- Labor costs: $300-$600 per door for professional installation
- Size and customization: Standard sizes cost less; custom doors can add $500-$2,000
French doors add more than just curb appeal to your Chicago home. They flood rooms with natural light, create seamless indoor-outdoor flow, and consistently rank among the top features buyers look for. But when it’s time to replace drafty, rotting, or outdated French doors, understanding the true cost—not just the door itself, but installation, materials, and those surprise expenses—can feel overwhelming.
The price you’ll pay depends heavily on your choices: the frame material, glass options, door size, and whether you’re doing a simple swap or need structural work. Exterior French doors cost roughly twice what interior ones do because they need weatherproofing, reinforced frames, security features, and energy-efficient glass that stands up to Chicago’s temperature swings.
I’m Steve Mlynek, and over my 20+ years installing doors across Chicagoland, I’ve helped hundreds of homeowners steer the cost to replace exterior french doors while balancing quality, energy efficiency, and budget. In this guide, I’ll break down exactly what you’ll pay and why, so you can plan your project with confidence.
Average Cost to Replace Exterior French Doors
When we talk about the cost to replace exterior french doors, we have to look at the total project. It isn’t just about the doors you see on the showroom floor in Arlington Heights or Des Plaines; it’s about the labor, the removal of the old unit, and the specific requirements of your home’s structure.
In the Chicago market, we generally categorize costs into three tiers:
- Budget Tier ($1,300 – $2,500): This usually includes a standard-sized vinyl or steel door with double-pane glass. These are functional and provide decent energy efficiency but may lack the high-end aesthetic of wood or fiberglass.
- Mid-Range Tier ($3,000 – $5,500): This is the “sweet spot” for most of our clients in suburbs like Schaumburg and Palatine. You’ll find high-quality fiberglass or mid-range wood doors with better hardware and energy-efficient coatings.
- High-End or Custom Tier ($6,000 – $15,000+): If you are looking for oversized doors, custom decorative glass, or premium clad-wood systems from brands like Marvin or ProVia, the sky is the limit.
Breakdown of Professional Labor
Labor is a significant part of your budget. For a straightforward “retrofit” (replacing an old door with a new one of the same size), you can expect to pay between $300 and $600 in labor per door. However, if we need to repair water damage in the subfloor or resize the opening, that labor cost can climb. Professional installers in the Chicago area typically charge between $70 and $120 per hour.
Material and Longevity Table
To help you visualize the value, here is how different materials stack up regarding the cost to replace exterior french doors:
| Material | Material Cost (Door Only) | Durability | Average Lifespan |
|---|---|---|---|
| Vinyl | $500 – $2,000 | Moderate (can warp in extreme heat) | 15–20 Years |
| Steel | $700 – $3,000 | High (excellent security) | 20–30 Years |
| Fiberglass | $850 – $4,500 | Very High (mimics wood perfectly) | 30–40 Years |
| Wood | $300 – $2,000* | Moderate (requires maintenance) | 20–30 Years |
| Clad-Wood | $2,500 – $5,000 | High (wood inside, aluminum outside) | 30+ Years |
*Note: High-end hardwoods like Mahogany can exceed $4,000.

Material Impact on Cost to Replace Exterior French Doors
The material you choose is the biggest variable in your final invoice. In our region, from Evanston down to Elmhurst, the weather is our biggest enemy.
- Fiberglass: We often recommend fiberglass for Chicago homes. It doesn’t warp like wood or rust like steel, and it offers superior insulation. While the upfront cost is higher ($850–$4,500), the lack of maintenance makes it a winner.
- Steel: Steel is the champion of security. It’s often more affordable than fiberglass but can be prone to dents and may not offer the same “warm” look. To learn more about this material, read our guide on the advantages and disadvantages of steel replacement doors.
- Solid Wood: Nothing beats the beauty of real oak or cherry. However, in the North-West Suburbs, the humidity and snow mean you’ll be refinishing these doors every few years to prevent rot.
- Vinyl: The most budget-friendly option. It’s low maintenance, but standard vinyl frames can be thicker, offering less glass area.
- Aluminum: Lightweight and modern, though not the best insulator for our freezing winters unless it has a thermal break.
- Clad-Wood: This is the best of both worlds. You get the warmth of real wood on the inside of your home and a durable, weather-resistant aluminum shell on the outside.
Glass Types and Energy Efficiency
Since French doors are essentially large windows you can walk through, the glass choice is paramount. In a city where it can be 90°F in July and -20°F in January, energy efficiency isn’t just a “nice to have”—it’s a requirement.
- Double-Pane Glass ($700 – $3,000): This is the industry standard. It consists of two layers of glass with a space (usually filled with Argon gas) in between.
- Triple-Pane Glass ($800 – $5,000): For maximum noise reduction and insulation, triple-pane is the way to go. It’s significantly heavier and more expensive but can save you a bundle on heating bills.
- Low-E Coatings: These microscopic metallic layers reflect heat. In the summer, they keep the heat out; in the winter, they keep it in. This usually adds $350 to $1,000 to the door cost but pays for itself over time.
- Safety Glass: By law, exterior doors must use tempered glass, which breaks into small, dull cubes rather than sharp shards. For added security, you might consider laminated glass, which stays intact even if shattered.

Factors Influencing the Cost to Replace Exterior French Doors
Beyond the door itself, several logistical factors will sway your quote.
Door Size and Height
A standard French door unit is 72 inches wide by 80 inches tall. If your home in Barrington or Lake Zurich has 9-foot ceilings and requires an 8-foot door, expect the price to jump by 30% to 50%. Custom sizes are common in older Chicago homes where the original openings don’t match modern “off-the-shelf” standards.
Swing Direction and Style
- In-swing: Most common. The doors open into your room. You need to ensure you have the floor space for the “arc” of the door.
- Out-swing: Great for small rooms. Since they swing outside, they are also harder to forced-entry, but they require a clear patio area.
- Sliding French Doors: These look like traditional French doors but operate on a track. They are excellent for saving space and often cost between $800 and $2,000 for the unit.
- Telescopic Designs: These involve multiple panels that slide and stack. These are high-end “moving glass walls” and can range from $1,500 to $6,000+.

Labor and Installation Complexity for Cost to Replace Exterior French Doors
Not all installations are created equal. We look at two main types:
- Retrofit (Simple Swap): We remove the old door and “drop in” a new pre-hung unit. This is the fastest and cheapest method.
- New Construction / Structural Change: If you want to turn a single door and a window into a large French door system, we have to cut into the wall. This requires a structural header to support the weight of the house above the new, wider opening. Adding a header and reframing can add $150 to $8,000 to the project depending on if the wall is load-bearing.
We also have to consider the exterior finish. Installing a door into brick (common in Chicago) is more labor-intensive than installing into vinyl siding. You can learn the nitty-gritty of the process in our exterior door installation 101 guide.
Customization and Potential Hidden Costs
When budgeting the cost to replace exterior french doors, don’t forget the “little” things that add up:
- Decorative Glass: From frosted privacy glass to intricate leaded designs, this can add $500 to $2,000.
- Designer Hardware: A standard lockset might be included, but a multi-point locking system (which we highly recommend for security) or designer handles can add $100 to $500.
- Sidelights and Transoms: Adding windows to the sides (sidelights) or top (transoms) of your doors can cost $300 to $1,200 per unit.
- Disposal Fees: Tossing the old, heavy wood and glass doors usually costs $50 to $150.
- Permit Costs: Most Chicagoland municipalities require a permit for exterior door replacement, ranging from $50 to $200.
- Weatherstripping and Trim: High-quality sealants and interior trim work usually add $100 to $300 to the final labor bill.

Comparing French Doors to Other Patio Options
Many homeowners ask us if the cost to replace exterior french doors is worth it compared to a standard sliding door.
- Sliding Glass Doors: Generally the most affordable patio option. A standard installation costs $700 to $2,400. They offer a more “modern” look and don’t require any swing space.
- French Doors: Offer a timeless, neat look. They allow for a wider opening (since both doors can open), which is great for moving furniture or hosting parties. They are typically $1,000 to $2,000 more expensive than sliders.
- Bi-fold Doors: These are the ultimate luxury. They fold like an accordion to completely open a wall. These are the most expensive, often starting at $5,000 and going up to $30,000.

Frequently Asked Questions about French Door Replacement
Do French doors add value to a home?
Absolutely. French doors are seen as a premium upgrade. They improve the aesthetic of the home, increase natural light (which makes rooms feel larger), and provide that sought-after indoor-outdoor connection. Most homeowners see a significant return on investment through increased resale value and buyer interest. You can read more about door and window replacement benefits here.
How long do exterior French doors last?
An exterior French door unit typically lasts 15 to 30 years. The lifespan depends heavily on the material. Vinyl may last 20 years, while high-quality fiberglass or steel can easily push past 30. Regular maintenance—like checking the weatherstripping and painting wood frames—is key. Check out our exterior door installation FAQs for more maintenance tips.
Is it cheaper to repair or replace French doors?
If you have a minor issue like a broken handle or a drafty seal, repair is the way to go (costing $100–$300). However, if you see condensation between the glass panes (seal failure), rotting wood, or a warped frame that won’t lock properly, replacement is the more cost-effective long-term solution. Trying to “fix” a warped door is often a losing battle against Chicago’s humidity. Consult our front door installation guide to see if your door is a candidate for a swap.
Conclusion
Replacing your exterior French doors is a significant investment in your home’s comfort, security, and beauty. While the cost to replace exterior french doors can vary widely based on whether you’re in the heart of Chicago or out in the suburbs like Hoffman Estates or Wood Dale, the value they add is undeniable.
