A house with a brick exterior often has aluminum windows attached to a wooden frame. An aluminum window is normally glazed that has a sash and can sometimes come with a mullion if a wall in a house is load bearing. A brick house, depending on its age, may have aluminum windows since, unlike wooden windows, they do not rot or sag.
Measure the size of the window to find the width and height for the new replacement.
2
Purchase a replacement window from a home improvement store. If the measurements are for a non-standard window size, a custom window will need to be ordered.
3
Examine the window opening to see what tools will be needed to take it out of the wall. An aluminum window in a brick house is held in place with either screws or nails, depending on its age. The screws can be removed with a screwdriver or drill and the nails may need to be cut with a Sawzall.
4
Pull the aluminum window out of the wall by grabbing from the bottom near the sill and sliding it out. Remove debris, such as nails or screws, from around the bottom of the sill.
5
Place the new replacement window into the opening. Secure the window with the included screws. There are usually two to three places on each side to secure a screw, depending on the size of the window.
6
Seal gaps between the window and the wall. Apply a bead of caulk around the edges of the window. Do this to the inside as well as the outside of the window.
