Worried about winter heating bills? Or just wishing your home wasn’t so drafty? We’ve already covered the perfect DIY solution #1: installing storm doors. What’s the perfect DIY solution #2? Installing storm windows. They alone can save you between 12 and 33 percent on your heating costs and are much cheaper than replacement windows. Plus, installing storm windows is easy, with our expert how-to advice.
Make Your Choice – Interior or Exterior Storm Windows
Determine what type of storm windows you’d like – interior or exterior. Exterior models come with solid windows and screens in frames that attach directly to an existing window. Interior storm windows are usually seasonal products that you install every winter. They snap or clip into your interior windowsill but do not have adjustable glass panes or screens.
Exterior storm windows are the most common. Frames are made from wood, aluminum or vinyl and offer extra protection to your existing windows. They help them last longer and require less maintenance to the paint and caulk. Most have low emissivity glass (Low-E), which keeps thermal heat in during the winter and infrared heat out during the summer.
Installation is a simple DIY home project that you can tackle in a weekend (depending on the number of windows you have). To start, you will need the following:
- Measuring tape
- Caulk and caulk gun
- Paint scraper
- Ladder (for second story windows)
Measure, Measure, Measure
Take a series of measurements of the inside of your existing window, at the bottom, top and middle of the frame. Why? The window frame may not be straight. Use the smallest measurement to order your storm windows. Measure the height of the frame from the outside of your window.
Consider ordering your windows with some of the following features:
- Multiple positioning stops so you can raise or lower the panes to where you want.
- Quality weather stripping to help stop heating/cooling loss.
- Pre-drilled holes for quicker installation.
- Easy-to-clean removable half pane glass and screens to make spring cleaning easier.
Drill Weep Holes then Paint
Storm windows come with weep holes installed at the bottom. Drill matching holes in the bottom exterior windowsill. This will allow condensation to escape. Next, scrap and paint the exterior frame before installing the new window.
Seal Your Storm Windows
Manufacturers recommend applying Butyl caulk, a rubber-based sealant that is good for outdoor installations like siding and gutters. It is a little uncooperative to work with, but it seals better than a silicone caulk. Apply it to the back of the storm window before installing to the exterior frame.
An Extra Set of Hands Comes in – Handy
You may need an extra set of hands to help hold the storm window while you mount it. First center the window then screw it in at top. Close the bottom sash and then screw the sides to the exterior frame. There will be an adjustable expander at the bottom of your storm windows. Tap it down tight against the windowsill and you are done.
Look for Condensation and Fix Air Leaks
Be sure to check your storm windows for condensation during the next cold snap. Leaks from your interior windows can cause moisture build up. This is no problem since the storm window has weep holes, but you may want to follow up with new weather stripping on your interior sill to plug possible air leaks.
Take a Bite Out of Your Next Power Bill
Cutting down on heating bills is always a challenge. Improving your home’s insulation, plugging air leaks and installing storm windows will go a long way to take a bite out of that next bill. Next time the cold wind blows and you sit warm inside, remember to thank your storm windows. Everyone likes a nice pat on the back from time to time.
