How to Install Wood Storm Windows How to Install Wood Storm Windows

Wood storm windows are less expensive than other types of storm windows but are equally as effective in insulating your house. For the homeowner interested in reducing costs of heating or cooling, these windows are a must. Over time, your heating and cooling costs will be reduced enough to pay the costs of adding these windows, particularly in colder or hotter climates. In addition, installing these windows, yourself, will further reduce their cost. All you will need to install storm windows is a few basic tools and some easy-to-follow instructions such as those below.

What you'll need:

Tape measure

  • Pencil
  • Notebook
  • Paint scraper
  • Caulk gun
  • Window cleaner
  • Drill
  • 1/8" drill bit
  • Caulk
  • Putty knife

Step 1 – Measure Window Dimensions

For ordering or purchasing your storm windows, you'll need to know the dimensions of the window openings into which you will install your new windows. So, carefully measure at the window interior window frame the height and width of one of these windows. You'll need to measure at three places in the window:  1) left side, 2) right side, and 3) middle. In order for your new storm window to fit, you'll need it to meet the smallest of these dimensions. So, in a notebook, make a note of the smallest of these three measurements.

Step 2 – Clean and Caulk your Window Frames

To get your window frames ready for the new windows, smooth the surfaces of the window frames by removing any loose or flaking paint, old caulking, dirt, or debris you find on these frames. To remove loose or flaking paint, use a paint scraper. If any of the frame paint has worn away or removed when you scraped, clean off all debris from the frame's surface and apply a fresh coat of caulk and paint to make the window more air tight and watertight.

Step 3 – Clean your Windows

Clean the outer surface of the interior windows to which you'll be adding the new storm windows. Once you attach your new windows, these interior window surfaces will not be accessible for you to clean. Use a good cleaner that won't streak.

Step 4 – Make Weep Holes

Into each of your window sills into which you'll be installing a storm window, drill atwo1/8" holes that will allow moist air between your interior window and your storm window to escape, one at each side of the sill.

Step 5 -  Clean and Caulk the New Storm Windows

Using butyl caulk that will remain pliable, is paintable, and will make the window's seal more weather tight, caulk the top and side edges of the new storm window. When finished with this caulking, clean off any smudges, dust, or fingerprints from the inside glass surface that might have become dirty when you applied caulk to it.

Step 6 – Attach the Storm Window

Slide the new window into place and insert the screws that will secure it in the window frame. Finally, use a hammer and putty knife to secure the flashing along the storm window's bottom edge. This will make the window fit more tightly and ensure that it is more weatherproof.
