Trying to decide if this project is right for you? We’ll walk you through some preliminary steps you can take to assess the feasibility of converting a window into a door — plus we’ll help you start thinking about cost.
Maybe you want a more convenient entrance, better connection to your outdoor living space, or the option to bring in abundant fresh air and natural light — or maybe you’re looking to add all of the above. Whatever the case, you should know that turning a window into a door is a common project and often completely feasible.
We’ll walk you through some preliminary research you can do to begin assessing how such a project might work in your own home. Take these steps before you call a pro, and you’ll be better prepared to ask good questions and have a more nuanced understanding of pricing.
If you think converting a window into a door is the right move, you can get started by looking closely at your space, thinking through your vision, and doing a bit of research. Here’s how to start planning and preparing:
First and foremost, take a close look at the space from both the exterior and interior. Understanding existing conditions can clue you into whether your project is going to be larger or smaller in scope.
Bottom line: You don’t need to have all the answers as to how the project could be accomplished at this point. A pro will help with that. Instead, you want to focus on identifying aspects of the existing window that could expand the scope of the project. This gives you a chance to consider how big of a project you're willing to take on. It will also help you think through good questions to ask your pro.
What type of door are you imagining? The answer to this question will give you more insight into the changes that might be required and the type of door that might fit your budget.
Bottom line: A successful conversion will likely include modifying your rough opening. A rough opening is the hole in the wall where a window or door fits. The door you select will dictate what kind of modifications will be required, but generally, the more dramatic the change, the more modifications will be needed. So, thinking about the door is an opportunity to decide how big the scope of your project should be. It’s also an opportunity to start considering the cost of the door. Broadly speaking, a larger door will come at a larger price.
When this Ranch home was remodeled, the homeowner went all in on indoor/outdoor living by replacing a standard back door and row of windows with a Folding Outswing Door. The new door opens up her entire back wall to the deck and backyard.
Getting a rough idea about the size of your window can be helpful, especially if you are looking at a simpler conversion — like replacing a large window with a single-panel door. Measuring the window can help you begin comparison shopping. For example, our doors are sold at The Home Depot® stores as well as building supply dealers. You could visit either if you want to start understanding what a new door might cost.
Bottom line: The measurement needed to actually order a door will be technical and could be complicated by the fact that your rough opening might need to be adjusted. This is yet another reason that we recommend working with a pro on a project like this. Still, taking a rough measure will help you start understanding door prices.
Depending on your city, county, or state, you may need to explore necessary permits or approvals before you begin your project. This process may affect the timing or total cost of your window-to-door transformation, so don't be afraid to ask for advice from your contractor or trusted professional if you have questions along the way.
Bottom line: It’s always a good idea to ask your contractor how they usually approach the permitting process. A good contractor will have an understanding of local regulations, but it doesn’t hurt to confirm that they will take responsibility for pulling the necessary permits.
The cost of converting a window into a door will depend almost entirely on the design you have in mind and the scale of the project itself. While it should be expected that the price for this type of transformation will be higher than a standard window replacement, here are a few important factors that will have the biggest impact on the final price tag:
Your labor costs will be impacted by both the complexity of the project and your home's location. Prices may vary based on your regional labor market and the amount of time your project will take to complete.
The cost of materials for your window-to-door conversion project will be based on the door type, its frame, and any hardware that you choose. Be sure to ask your contractor about any supporting materials that may be needed to maintain the structural integrity of your home.
Speaking of structure, if the conversion requires significant changes to a room (such as reinforcing a wall), the cost of your project will likely increase. These measures will be taken to preserve the safety and durability of your home and should be accounted for when thinking about your total budget.
Depending on the location of the new door, you may need to modify your home's siding or trim. This can add costs in terms of labor, materials, or any additional work needed to protect the function or form of your exterior. Some materials are easier to modify than others. For example, brick and stone facades will likely be more challenging and costly to modify.
Bottom line: If you are considering DIY, we advise you to speak with a pro first to make sure you understand the full scope of the project. You may learn that the steps involved go beyond your experience. For example, you might need to calculate structural loads in order to frame the new opening correctly.
Once you've made your game plan and have considered all the potential costs and considerations, you are ready to learn more about the logistics of window-to-door conversion. Although every home is unique, here are the basic steps that you can expect to encounter after your project officially begins:
1. Removal of the window
Your contractor will carefully remove the existing window, including its frame, glass, and trim.
2. Preparation of the opening
The window opening will be modified to accommodate the new door size and frame, and any necessary reinforcements will take place to protect the structure of your home's walls and frame.
3. Installation of the door and door frame
The door frame will be secured in place, and the panel will be adjusted for proper function and fit.
4. Finishing touches
All of the necessary finishing work will be completed, including painting, caulking, and the trim installation.
