Things You'll Need
Wear safety glasses to protect your eyes from flying debris.
Replacing an old or damaged window frame in a garage is a task that can be completed by anyone with the correct tools and a little carpentry know-how. If your home needs a new garage window, there is no need to hire a costly handyman or carpenter if you already possess the right equipment and are familiar with operating power tools. Replacing the garage windows can beautify both the outside of a home and the inside of a garage. It can also provide your garage with enhanced natural lighting.
Tap the ripping chisel with a hammer behind trimming of window and remove trim. Do not worry about nails pulling through the trim as long as they are finish nails. Pull out any remaining nails with the ripping chisel or hammer.
Place the reciprocating saw with a metal cutting blade in between the window frame and wall stud and cut nails around the whole window.
Slide out the window frame from the framed garage wall. Use a mallet or hammer to tap out the window if needed. You may need to cut the paper flashing around the window with a utility knife. Cut remaining length of nails so that they are flush with the trim.
Slide the new window frame into the framed wall. Place a level on top of the sill and level. Use shims to wedge the sill until level and nail the bottom sill of the window frame so that it sits on the center of the framed wall opening. Place a four-foot level against the outside edges of the window and level. Use shims to adjust window so that it is plum and in place. Nail around all four edges with either finish nails or larger nails with predrilled holes.
Replace paper flashing if needed and staple it into place. Fill in any holes with a wood filler and sand down to make a smooth surface.
Paint or stain the window trim with weather-resistant materials.
