Replacing a Basement Window in Concrete

Damaged and outdated basement windows can let in extreme cold or humidity. Again, they sometimes develop cracks and start leaking. If you see any of these signs, it is time to replace your basement window and save on the cooling and heating costs.

Basement windows usually come with either window frames, which are secured in concrete, or steel bucks. Whichever the case, replacement is usually quite easy. Here is how you will go about replacing a basement window in concrete.

First, remove the sash components-including louvers, glass slats, and everything but the frame. What you remove will depend on the type of window, but the frames are left intact.

Next is to attack the frame in order to access the openings in the concrete. This is quite a tough one since the frame is secured to the concrete. Use the metal cutting blade of a reciprocating saw to cut deeply at the center of the frame’s bottom. It makes the frame weak enough so you can wedge a pry bar between the concrete and the frame.

Finish with one side of the frame before moving to the next. Grip the frame using the pry bar, then wedge it out of the opening. Steel frames are harder, and need to be cut on every side using the reciprocating saw.

Once you have assessed the rough opening in the concrete, you will be able to get the measurements for the replacement windows you will need to buy. Even if you had bought them, you still need the measurements to help you make relevant modifications so that the replacement fits well when you finally start doing the replacement.

Ensure you make all the necessary adjustments to the window, like trimming the fins on the window. There are no general modifications-it always depends on the specific situation and what doesn’t fit, which should be made to fit. Do not make any modifications on your basement replacement window unless you have checked to ascertain that the changes you intend to make are the best.

Next, stick the window in the opening, and ensure it fits well.

To access the screw holes, take off the sashes and screen from the window. For a slider, lift the sashes and screen panel one by one and keenly. Remove them until the bottom track is cleared.

Install double-threaded concrete screws along the top and the sides of the window. This will help to secure the window in place

If the replacement window has screw cover plugs, install them. After that, you can now fit back the sashes and screen back into the window.

The gap between the cement and window should then be caulked on the inside.

Fill the gap between the cement and the window and use spray foam to cement. If the strip of solid foam on your replacement window’s edge is exposed, tear it off before you apply the spray foam. This ensures that the insulated seal is tighter
