Installing a single hung window can enhance your home’s energy efficiency and overall aesthetics. Proper installation is key to ensuring the window functions well and lasts for years. Single-hung windows are commonly found in older homes, but are not as common when looking for replacement windows. Unlike double-hung windows, which allow both the top and bottom sashes to move, only the lower sash of a single-hung window can be raised.
Key Takeaway
Installing a single hung window involves careful measurement, removal of the old window, precise placement of the new window, and secure sealing to prevent drafts and improve energy efficiency.

Preparing for Installation
Proper preparation is crucial for ensuring a smooth installation process.
Measuring the Window Opening
Accurate measurements are crucial for a proper fit. Measure the width and height of the window opening at three points: top, middle, and bottom. Use the smallest measurement to ensure the window fits.
Removing the Old Window
Carefully remove the old window by prying off the exterior trim and unscrewing the window frame. Clean the window jamb and sill, removing any debris or old caulk to prepare for the new window installation.
Installing the Single Hung Window
Follow these steps to install your new single hung window.
Positioning the Window
Place the single hung window into the window opening, ensuring it is centered. Rest the bottom of the window along the sill. Verify that the gap on each side of the window is about 1/4 inch and the gap above the window is about 3/4 inch. Remove the window.
Securing the Window
Measure the width of the window opening with a tape measure, and cut a piece of flashing tape 4 inches longer than the width of the opening. Remove the backer and install the tape with 2 inches extending past each end and 2 inches overlapping the front, outside edge of the frame. Cut the corners of the flashing tape diagonally to allow the corners to fit into the frame smoothly.
Installing Flashing Tape
Cut a piece of flashing tape about a foot longer than the width of the window, and apply it over the nailing fin beneath the window. Repeat with two strips for the sides of the window, followed by one across the top.
Final Securing
Tack a 2-inch galvanized roofing nail through the nail strip in one of the upper corners of the nailing fin of the window with a hammer to hold the window in place in the frame. Go inside the building and check the window for level and plumb. Insert additional shims between the window around the frame as needed to keep the window plumb and level. Return outside, and tack the remaining three corners of the nailing fins with 2-inch nails.
Insulating and Sealing
From the inside, open the window sash to see if it opens and closes smoothly. If it pinches, adjust any shims on the sides of the window until the window sash moves easily. Return outside, and hammer a nail through every hole in the nailing fin.
Return inside, and spray a very thin bead of foam insulation in the gap between the window and the frame. After the first bead expands, apply a second and then a third until all air pockets within the gaps have been filled.
Installing Interior and Exterior Trim
Reattach the interior and exterior trim around the window. Ensure a tight seal by applying caulk along the edges of the trim to prevent water and air infiltration.
Final Checks and Adjustments
Test the window to ensure it operates smoothly. Make any final adjustments needed to ensure proper function and a secure fit.
Common Mistakes to Avoid
Avoid these common pitfalls to ensure a successful window installation.
Not Measuring Accurately
Always double-check your measurements to ensure a proper fit. Incorrect measurements can lead to poor installation and energy loss.
Skipping Insulation
Insulation is crucial for energy efficiency and preventing drafts. Make sure to properly insulate around the window frame.
Over-Tightening Screws
Over-tightening screws can warp the window frame and affect operation. Tighten screws just enough to secure the window without distorting the frame.
