Egress windows are the unsung heroes of home safety and utility. They offer healthy ventilation, a crucial emergency escape route, and a gateway for natural light in basements or other dimly lit lower-level areas. If you're contemplating how to install an egress window, we'll be your trusty companion. This guide shares each step to ensure your DIY project is a bright success. Would you rather keep your tools in the shed? You can also hire an egress window installer near you. But first, let's shine some light on the installation process.
How Hard Is It to Install an Egress Window?
Installing an egress window is a challenging task that requires careful planning, precise measurements, and a fair amount of manual labor—not to mention adherence to local building codes and obtaining construction permits. Also, cutting through a masonry wall and your home’s foundation is tricky. If done wrong, it could compromise the structural integrity of your abode.
However, if you have previous building experience and feel confident in your construction abilities, installing an egress window can be a rewarding and achievable undertaking. Alternatively, consulting with a professional contractor can ensure a smooth and successful installation.
Preparing to Install an Egress Window
Before starting your project, consult a structural engineer to ensure a safe and compliant installation. They can assess your home’s foundation’s structural integrity, advise on modifications, and ensure your project meets safety requirements. The expected cost for their services averages around $525. Your location will impact the price.
Additional Costs and Expenses
Significant factors influencing egress window costs are type, glass quality, and energy efficiency rating. Factory-made egress windows start at $100,with the average price hovering around $450.Made-to-order egress windows, on the other hand, start at $500.Additional materials, like a light well for each window and insulation, can add significantly to your total cost,starting at around $300 per window.
If you hire a pro, labor costs begin at $40 per hour, again depending on where you live. You can expect to pay $120 to $250 for each window installed, not including excavation and framing.
Depending on the number of windows, the project can take up to three days for an experienced professional or an expert DIYer. There are three primary steps in the installation process: excavation, framing, and installation. More on that shortly. Estimated total costs for labor and materials, not including a consult with a structural engineer, can range between $2,500 and $5,300.
Location and Measurements
Determine the ideal location for the egress window, considering accessibility, light, and aesthetics. Mark the area and check for potential obstructions, including utility lines.
To measure for an egress window, begin by determining the required window opening size based on local building codes. Measure the designated window area's width, height, and depth from inside the basement to ensure the window fits appropriately. It's always advisable to consult the manufacturer's guidelines for specific measuring instructions to ensure an accurate fit.
Excavation and Foundation Preparation
Start by excavating the exterior area outside the wall to the required depth using a shovel, ensuring adequate space for a window well. The depth for your project is dependent on local regulations, but typically, a window well has a required depth of 44 inches to ensure sufficient space for safe exit. Remember that the hole outside the window should be deep enough to accommodate the well and drainage. Afterward, remove any debris with your wheelbarrow and level the base.
Next, prepare the foundation wall by cleaning it thoroughly and removing any loose material. You will need a bucket, a scrub brush, and an exterior house cleaner solution. If you own an electric power washer, you can get the job done quicker. Remember that you don’t want the area to get super wet and muddy, so consider covering the ground with a tarp.
Afterward, measure and mark the window opening on the inside wall per the manufacturer's specifications. Use a concrete saw to carefully cut through the foundation wall, following the marked lines created for your new window.

To properly install the window well, start by placing a layer of gravel at the bottom of the hole. It helps with drainage and provides stability.
Once the gravel is in place, position the well against the exterior wall, ensuring it aligns with the window opening. Take care to align it accurately for a proper fit. Secure the well to the wall using screws or bolts, ensuring it is level and plumb.
Backfill the Window Well and Test for Drainage
After securing the well to the wall, backfill the hole with soil. Pack the soil tightly around the well to provide additional support and stability. You can install a window well cover for added safety and protection if desired. These covers help prevent debris from accumulating in the well and can serve as a safety measure, particularly for households with children or pets.
Once the installation is complete, it is essential to test the drainage system. Pour water into the well and see if it flows away. Proper drainage is crucial to prevent water accumulation and potential damage to the window and surrounding area.
Now let’s kick off the window installation; this part of the process requires intermediate carpentry skills. Measure the dimensions of the window opening and cut pressure-treated lumber to create the framing components. Typically, you must construct a header, sill plate, and vertical studs from the lumber.
Install the Sill Plate, Header, and Studs
Place the sill plate at the bottom of the window opening and secure it to the floor using appropriate fasteners. Ensure that it is level and securely anchored.
Now, position the header horizontally at the top of the window opening, perpendicular to the vertical studs. Make sure it is level and centered. Attach it securely to the surrounding structure using a hammer and nails or drill and screws.
Next, space the vertical studs evenly along the sides of the window opening, attaching them to the sill plate and header. Use a level to ensure they are plumb (vertically straight) and securely fasten them to the framing members.
Secure Additional Framing Elements
Depending on the specific requirements and building codes, you may need to install additional framing elements such as cripple studs, king studs, or jack studs. Follow the window manufacturer's instructions and local building codes for guidance.
Check for Stability and Squareness
Ensure the framing is stable and properly aligned. Use a level to check for both vertical and horizontal alignment. Make any necessary adjustments to ensure the frame is square and sturdy.
Testing the Fit
Following the manufacturer's instructions is best when installing your new egress window, but the first step is always testing the fit.
To do so, align it with the framed opening you created, rest it on the sill, and tilt it forward into place. Consider the surrounding walls and ceiling, ensuring enough space for proper hardware engagement and hand clearance on the handle.
Fasten the Window
The specific screw placement will vary depending on the window, wall, and frame used for installation. Typically, you would start by adding shims after testing the fit. Shims help with alignment or function as spacers for insulation. More on that later.
Next, pop in the window and fasten it to the wood frame with galvanized or stainless-steel screws. Now ensure that your new window opens and closes properly.
Insulate the Window
Apply weather-resistant sealant between the window frame and wall opening, ensuring a tight seal to prevent drafts and moisture intrusion. We suggest adding expanding foam or other suitable insulation materials to fill gaps. You may need to trim the shims and keep them in place before sealing.
Finishing Touches
Finish the interior and exterior of the egress window to match the existing surroundings. Consider installing drywall, trim, and paint on the interior, ensuring a clean and professional appearance.
