Installing an egress window can provide your home with improved safety, natural light, and ventilation. If you’re ready to take on this home improvement project, follow this step-by-step guide to installing an egress window.
1. Plan and Prepare
First, determine the location for your egress window. You’ll need to make sure it meets local building codes and provides easy access to escape in case of an emergency. Be aware of any underground utilities or obstructions that could be in the way when digging.
2. Get the Necessary Permits
Most cities require permits for egress window installations. Visit your local government’s website or call your city hall to inquire about the necessary permits and inspections for your project.
3. Measure and Mark Your Cut Lines
Using a tape measure, mark the outer dimensions of the window on the exterior wall. Make sure the area is level and square. To achieve clean lines, use a straight edge or a chalk line to draw along the space where you want to install the egress window.
4. Dig The Window Well
If you’re installing a basement egress window, dig out the area around your markings to create a hole deep enough for your window well assembly. The size of your hole may vary depending on local building codes or basement depth.
5. Frame and Cut Your Opening
Before cutting through your wall, frame out the rough opening according to the manufacturer’s instructions from inside the house or building. With a partner holding onto one side of a heavy-duty circular saw, cut through both layers of foundation wall along your marked lines at each corner where you drilled pilot holes in step 3.
6. Remove Concrete Wall Material
Using a masonry chisel and hammer, chip away at the concrete along each side of your opening until nice squared edges are achieved—take great care not to damage your rough framing. Remove excess material and dispose of it properly.
7. Install Window Assembly
Consult the manufacturer’s installation instructions for the proper method of attaching your egress window to the rough opening. For some models, this may involve reinforcing the frame with steel brackets or installing a preassembled window unit. Ensure the assembly is level and that all galvanized screws are secure.
8. Install Window Well
Slide your window well into position based on its orientation and size requirements. For added stability, attach window well brackets to the outer foundation wall using expansion bolts or masonry screws. Fill in any gaps between the well and window with drainage gravel, making sure that water can exit freely.
9. Waterproof and Insulate
Apply caulking or weatherstripping along the interior edges of your egress window to ensure no water or air penetrates the opening. Additionally, cover any exposed insulation with drywall or a suitable material for a finished appearance.
10. Complete Final Inspection
Once everything is installed, double-check your work to make sure all components are safely secured and operational—ensuring that the egress complies with local building codes and safety standards.
By following these ten steps, you can successfully install an egress window in your home, providing added safety and comfort for you and your family. Always remember to consult with an experienced professional if you have any doubts or questions about installation procedures.
