Whether you have a growing family or want to add short-term rental opportunities to your home’s lower level, remodeling your basement is a great opportunity to expand your living space. But if a concrete wall is standing between you and your ideal design—which includes a new entry point—you may be wondering if it's possible to add in a door. While the answer is generally yes, your home’s concrete walls are often load-bearing or foundation walls and can be difficult to modify or remove.
It costs $3,000 on average or between $1,300 and $4,500 to install a door in a concrete block wall. The job entails cutting an opening in the wall, adding a frame, and installing a new door. The final price varies based on the size, location, and any structural changes in load-bearing walls.
This is why inserting a door can be tricky when the wall is load-bearing. In this case, you should contact a local structural engineer to analyze and design the support to replace the part of the wall you will be removing.

How Much Does It Cost to Install a Door in a Concrete Block Wall?
The price varies depending on the location of the door. Installing an interior door in a concrete block wall runs between $1,300 to $2,200, whereas the cost to install an exterior door in a wall is $1,400 to $4,400.
You can add an extra $400 to $800 to your budget if you want to create a larger wall opening.
Installing a Door in Concrete Block Wall Cost Breakdown
The final cost of installing a door in a concrete wall depends on aspects, such as the doorway's size and location and any structural changes. Here is a breakdown of the things you need to factor in.
Hire a Structural Engineer
Before breaking into a concrete wall, you’ll need to consult with a structural engineer to ensure the wall’s structural integrity can manage the project impact. Besides, most municipalities require a permit for this type of work because concrete walls tend to be load-bearing.
Hiring a structural engineer would cost $100 to $150 per hour at an average of $500 for the project. A structural engineer makes sure the home's structural integrity stays intact and provides a report with plans for the contractor to follow.
Cut an Opening
Cutting through a concrete block wall typically runs between $300 to $2,200. It can be even higher for double doors, exterior doors, or cutting through load-bearing walls.
Frame a New Doorway
Framing a new doorway opening averages $300 to $600. When installing a load-bearing header, expect to pay on the higher end of that range.
Install the Door
The average labor rate to install the door is about $70 per hour, ranging from $40 to $90 per hour. It can take a professional six to seven hours to frame and install a door, while it might only take them two to three hours to install a prehung door.
Installing a new door typically ends up costing around $500 to $1,600 depending on the location, the size, and the material of the door. It can cost up to $5,000 if you’re installing an entryway door made of heavy material.
Prehung Interior Doors
Prehung doors are ideal when you’re cutting a new doorway into a wall because they come with a solid frame to fit into the opening and can range from $60 to $1,000 or more, depending on the chosen material.
Expect to pay an additional cost of up to $1,200 if you have to reroute any plumbing or electrical work.
Cost to Installing a Door in Concrete Block Wall Yourself
While this might seem like a straightforward job, it can be challenging. It requires a certain level of home construction skills and tools, especially when cutting through the wall. Not to mention the structural measures that need to be taken to ensure your home is safe and sturdy with its new lower-level entry.
Consider requesting a quote from a company that specializes in concrete cutting. After the new doorway opening is complete, you may be able to save some project costs by installing a prehung door yourself.
Installing a Door in a Concrete Block Wall Questions and Answers
What other projects should I do at the same time?
While you have basement professionals in your home, you can also:
Tear down a wall: If you'd like to have an open layout, removing a wall might be something you're considering. Include this in your structural engineering project to determine if it is a load-bearing wall.
How do contractors cut a doorway in a concrete block wall?
Mark the opening size on both sides of the wall. The opening is usually two inches wider and one inch taller than the door size.
Add other markings on the top of the door frame for the steel lintel to support the load above the door. The lintel should be six inches high and six inches past each side of the frame and centered over the door to distribute the wall's weight to the sides of the door opening.
Using a circular saw with a masonry saw blade, a pro will cut (two inches) through the wall on both sides of the wall.
An opening is started in the middle of the concrete wall with a sledgehammer.
As the pro nears the edges of the opening, they may switch to a masonry chisel to prevent damage to the surrounding area.
Blocks are mended as needed to create smooth, solid edges to make installing the door frame easier.
A steel lintel is installed into the opening above the door, and any gaps are filled with masonry mortar.
Do I need a permit to cut through a concrete block wall to install a door?
Usually, permits are required when cutting a doorway in an exterior wall, cutting into a load-bearing wall, or converting a window to a door. If you have specific questions about your project or to obtain a permit, contact your municipal building department.
