How to Install Storm Windows

If you live in the Northeast, you know how bad storms can get during both the summer and the winter. Many homeowners choose to install storm windows in their homes because of their strength and the extra protection they provide for your regular windows. If you’re a DIY-er, you can do this yourself. Here, our window experts explain how to install storm windows:

The first thing you’ll want to do is measure your existing windows from the outside.

  1. With your measuring tape, measure the width of your window at the top, middle, and bottom. Use the smallest measurement.
  2. Then, measure the height of your window at the left, in the center, and on the right. Use the smallest measurement.

If you’re replacing old storm windows, unscrew the old ones and remove them. Then, clean off any old caulk and/or paint before installing the new ones.

  1. Once you receive your new windows, make sure they fit securely before installing them.
  2. Place your windows into the open window frame and take note of any gaps.
  3. If they fit, you can move onto the next step. If they don’t, you’ll need to adjust your window frame.
  4. Next, run a thin bead of caulk along the top and the sides of the outer edges of your window. (Be sure to not caulk the bottom so that moisture can run off the sill.)
  5. Install the storm window and make sure it’s centered.
  6. Lastly, screw the window into place using the pre-drilled holes. If there are no pre-drilled holes, drill holes 12″ apart and centered over the window stop.
