How Much Does a Window-to-Door Conversion Cost in 2025?

This article was updated using automation technology and thoroughly reviewed for accuracy by HomeAdvisor Editor Ryan Noonan.

The cost to convert a window into a door ranges from $1,200 to $12,000, with an average price of $6,300. Location, size, and material quality can significantly impact your budget, and hiring a professional door contractor ensures a safe and code-compliant installation. Planning your budget carefully can help you manage unexpected expenses as they arise.

Labor Cost to Convert a Window Into a Door

Labor costs to convert a window to a door average $3,050 or $150 per hour, depending on your location, the door style, and your carpenter’s experience. Most standard projects are completed within one to two days, unless major widening or structural work is required.

For complex projects involving multiple subcontractors, you may want to consider hiring a general contractor. A general contractor charges 10% to 20% of the project total and coordinates all subcontractors needed, including an electrician, structural engineer, siding installer, drywall installer, and carpenter. It’s common to have electrical circuits passing below a window, so it's best to also consult with a local electrician.

Here’s a breakdown of labor costs you’ll likely incur:

• Electricians cost: $160–$550

• Structural engineers' cost: $350–$750

• Drywall installation costs: $1.50–$3.50 per square foot

• Carpenters' cost: $75–$125 per hour

Window to Door Conversion Cost by Type

The cost of a window-to-door conversion varies based on door type, with prices ranging from $1,200 to $12,000. Larger options, such as French or sliding glass doors, can increase your total costs due to their more complex installation.

French Doors

The average cost to replace a window with French doors ranges from $3,500 to $8,500. This can be more expensive because you need to either widen one window opening or convert two windows to accommodate wide French doors.

Sliding Glass Doors

To replace a window with a sliding glass door costs $4,000 to $12,000. The sliding mechanism makes this type of door less expensive than some alternatives, and custom features like privacy blinds between the glass panels will increase the cost.

Additional Cost Factors to Convert a Window Into a Door

When converting a window to a door, several additional factors should be considered, including custom designs, permits, wiring, and the type of siding used.

Custom Designs

Custom design choices push your project toward the top of the price range. Exact costs depend on the materials you select, and every custom element adds extra labor to the final bill.

Permit

Building permits cost $100 to $1,000 or more, depending on local requirements. A permit is almost always required for a window-to-door conversion, which involves modifying siding and drywall, as well as rerouting wiring.

Wiring

Electrical circuits often run just below a window, so it's best to consult a local electrician for guidance. Rerouting the wiring above the new doorway is often straightforward, but it will still increase your overall cost.

DIY Window-to-Door Conversion vs. Hiring a Pro

The structural and electrical work involved in a window-to-door conversion means this project rarely suits the DIY approach. For most homeowners, hiring a local door installer or licensed general contractor is the safer route. 

DIY conversions range from $800 to $2,500, but they require advanced carpentry and electrical skills. Hiring a professional door installer costs $2,500 to $12,000 and delivers code-compliant results, as well as a polished finish.

Ways to Save When Converting a Window to a Door

A few strategic choices can keep your budget in check when converting a window to a door:

• Choose a pre-hung door instead of a custom design to save 20 to 30% on material costs.

• Select a standard-sized door that fits your existing rough opening with minimal modifications.

• Compare quotes from multiple contractors and negotiate labor rates during off-peak seasons.

• Reuse existing trim and hardware where possible to reduce material expenses.

• Consider energy-efficient options that may qualify for rebates or tax incentives.
