Window-to-door conversion costs average $1,200 to $12,000, with most projects ranging from $2,000 for basic conversions to $9,000 for complex or custom installations. The price depends on the size of the opening, the type of door material, and whether any structural modifications are required. Costs are often quoted on a per-project basis rather than per square foot.
If you’re considering this upgrade, you’ll want to understand the factors that impact both price and long-term value. This guide walks you through everything you need to know about the cost of converting a window to a door, so you can plan and budget with confidence.
The dimensions of your existing window and the desired door play a major role in determining project costs. A small window that’s being expanded for a standard door will require more structural work than converting a large window that’s nearly door-sized already.
Standard conversion sizes include single doors, French doors, and sliding doors. Larger or double-door conversions may require additional framing, wall modifications, and finishing, all of which increase the overall cost. Using the existing opening size is often less expensive than resizing the wall.
Conversion Type | Opening Size (In.) | Average Cost Range |
---|---|---|
Single door | 32–36 | $1,200–$4,500 |
French doors | 60–72 | $3,500–$8,500 |
Sliding door | 60–96 | $4,000–$12,000 |
The type of door you choose influences both the project’s complexity and its cost. Common options include standard exterior doors, French doors, sliding glass doors, and patio doors.
Each type offers different advantages in terms of aesthetics, security, and energy efficiency, but also comes with its own challenges. Custom doors cost more than standard sizes, especially if you want unique materials or features.
Door Type | Description | Cost Impact | Pros | Cons |
---|---|---|---|---|
Standard | Basic exterior, solid or paneled | Lowest | Secure, simple, affordable | Less natural light |
French | Double doors with glass panes | Moderate to high | Elegant, lots of light, wide opening | Higher installation cost |
Sliding | Large glass panels, slide open | High | Maximizes view, space-saving | More complex install |
Patio | Hinged or sliding, glass panels | Moderate to high | Connects to the outdoor space | Varies by configuration |
Custom | Any size/material, fully bespoke | Highest | Tailored fit/design | Most expensive |
Where you live affects the cost of converting windows to doors due to differences in labor rates, material prices, and local building codes. Urban areas often have higher labor costs than rural communities.
Some regions also require more extensive weatherproofing or have stricter permitting requirements, which can increase your budget. Always check with your local building department to understand the permit fees and any climate-specific requirements that may apply.
Several factors influence your total window-to-door conversion cost. Let’s break down the biggest contributors.
Professional labor is a major part of your window-to-door project budget. Contractors, carpenters, and sometimes structural engineers are involved, especially if the wall is load-bearing or requires electrical work. Hourly rates range from $50 to $150, depending on your region and the contractor’s experience.
Labor costs include demolition of the old window, framing the new opening, installing the door, and finishing work. More complex projects—such as those involving electrical rerouting or structural modifications—require more hours and higher expertise, driving up costs.
Most window-to-door conversions require at least a building permit, and sometimes additional structural or electrical permits. Building permit costs vary widely, from $100 to $1,000 or more, depending on your municipality.
Inspections are often needed before and after the work, and permit timelines can add days or weeks to your project. It’s important to factor in these costs and plan for potential delays due to permitting.
Upgrades can significantly add to your window-to-door conversion cost:
Sidelights, transom windows, custom glass, and decorative hardware all increase the final price.
Security features, such as reinforced or smart locks, are popular for exterior doors.
Energy efficiency improvements—such as insulated doors and advanced weatherstripping—enhance comfort and reduce long-term energy bills.
For accessibility, wider doorways and low thresholds are available, though these may require additional framing or hardware.
Beyond the basics, project complexity is a key driver of price. Converting a window in a load-bearing wall is more expensive than a non-load-bearing wall, due to the need for structural supports. Site accessibility, both indoors and outdoors, can also affect labor time and ease of installation.
Demolition, debris removal, and repairs to siding, drywall, or trim after installation all add to your total. If you choose a custom design, design, or architectural fees may apply. Finally, some projects require pre- and post-construction inspections, each with its own fees.
When budgeting for a window-to-door conversion, consider the following potential additional expenses.
Most new doors come with manufacturer warranties covering defects or premature wear. Your contractor may also offer a warranty on installation workmanship. While warranties can add a small upfront cost, they provide valuable long-term protection and peace of mind.
Ongoing maintenance depends on the material of your door. Wood doors need regular sealing or painting to prevent rot and may incur repair fees over time.
Fiberglass and steel doors are lower-maintenance but may still require occasional cleaning or touch-ups. Glass doors require cleaning and may need hardware or seal replacement over time. Annual maintenance costs range from $20 to $150, depending on material and exposure.
Sales tax on materials and labor applies in most states, so be sure to include this in your budget. In some cases, adding a new exterior door may slightly increase your property value, which could affect your property taxes. Check with your local tax assessor for details.
Adding a new door changes your home’s entry points and may affect your homeowners' insurance policy. Some insurers require you to update your policy, especially if security features or energy upgrades are added. Premiums may change based on perceived risk or an increase in home value.
Some homeowners consider converting a window to a door themselves to save on labor. While DIY can cut costs, it comes with increased risks and challenges.
DIY costs include materials, tools (such as saws, drills, and safety gear), and permit fees. You’ll need carpentry and finishing skills, and possibly experience with structural work or electrical rerouting. Expect to spend several weekends or more, as the project is time-intensive. Mistakes can lead to costly repairs, failed inspections, or even structural issues.
Hiring a local door installer costs more upfront but ensures safe, code-compliant work and a finished look. Professionals have the tools, skills, and experience to handle surprises and minimize risks.
Approach | Total Cost |
---|---|
DIY | $800–$2,500 |
Hiring a pro | $2,500–$12,000 |
Window-to-door conversions can offer a strong return on investment, especially if they increase accessibility, light, or connection to outdoor spaces. Many homeowners see an ROI of 60% to 75%, depending on location and quality of work.
This upgrade enhances curb appeal, functionality, and often boosts resale value, especially when incorporating energy-efficient or universally accessible features. Compared to other renovations, window-to-door conversions are a solid choice for both enjoyment and added value.
To keep your window-to-door conversion within budget, consider the following tips:
Get multiple quotes from licensed contractors for the best pricing.
Choose standard-size doors and avoid custom features when possible.
Reuse existing framing or hardware if in good condition.
Schedule work during off-peak seasons for potential discounts.
Handle demolition or finishing work yourself if skilled.
Purchase materials directly to avoid contractor markups.
Check for local rebates or incentives for energy-efficient doors.
