To replace and trim out a Basement Window, you will need to follow these basic steps:
1. Purchase Replacement Window(s)
The first step in replacing basement windows is to order your replacement window(s). To do this, measure the rough opening of you concrete foundation window penetration and compare those dimensions to available replacement window dimensions. There are many different sizes and styles of windows, so spend sufficient time ensuring that the replacement window you purchase will fit within your existing window penetration.

2. Remove the Existing Window
The second step in replacing a basement window is to remove the existing window. Start by removing any screws or nails that are holding the window in place. Then, remove the glass panels (if possible). Next, use a reciprocating saw to cut the top of the window frame and then try to loosen the frame from the concrete it is embedded within. If the window is stuck, use a pry bar to carefully loosen it from the home's foundation.

3. Position The New Window in Place
Position the replacement window into the opening and center it as best as possible. Use shims to hold the window in place.

4. Level the Window and Install Shims
To ensure the replacement window is level, use a carpenter's level to check for any unevenness. Use shims to make any necessary adjustments to the window's level, placing them in the gap between the window and the rough opening.

5. Apply Spray Foam around the Perimeter of the Window
Once the window is in place, secured with shims, and level, apply spray foam insulation around the perimeter of the window. The spray foam will help seal any gaps and improve the energy efficiency of your home. Be sure to follow the instructions on the spray foam can and wear gloves and protective eyewear during this step.

6. Cut off Excess Spray Foam and Caulk Around Window
After the spray foam has dried, use a utility knife to cut off any excess foam that is sticking out. Then, apply caulk around the exterior of the window to seal any remaining gaps. This will help prevent air and water from entering your basement. If you have a damaged any of the concrete around your window, you can repair it with rapid setting concrete and trowel at this stage of the project.

7. Trim out the Basement Window.
To install drywall a drywall return around a basement window, start by cutting drywall for the top and sides of the window. Cut they drywall such that it contacts the window’s frame on one side and so that it is flush with the wall drywall on the other side. Then, install corner bead and finish the drywall with joint compound. Caulk any joints between the drywall and window.

8. Install the Window Sill.
To cut your own window sill for a basement window, select a piece of lumber that is approximately 1.5″ wider than the depth of the basement window cavity. You may need to “rip” the lumber to a suitable width using a table or circular saw. Cut the off the sill so that it is 3″ longer than the window cavity on both sides. Next, use a router to give the window sill a rounded edge and use a jigsaw to cut the penetrations on both sides of the window sill – leaving a 3″ overhang on each side. Finally, caulk any gaps and paint the window sill (if desired)
