Replace Your Window’s Insect Screen in 15 Minutes– Week 4

I never knew how easy it is to replace an insect screen. Replacing a raggedy, old, dirty, used up insect screen also makes a HUGE difference. We have that ugly galvanized window frame but combined with the ripped up insect screen, it is just a hideous sight.

Here is the before and after picture of my window:

I have an easy DIY project coming up to make the galvanized window frame look a little more pleasant without having to change the entire frame. Changing window frames would cost way too much money and time AND expert contractor to install. I can’t wait to do this project!

Anyway, proceeding to how to replace your window’s insect screen in 15 minutes!

You will need:

Supplies needed to replace insect screen.

Supplies needed to replace insect screen.

  1. Insect Screen Material
  2. Roller
  3. Spline (you could reuse the old one!)
  4. Scissors
  5. Screwdriver
  6. Small pliers (may not need if old spline is easy to remove)

You can get a little kit at Home Depot for less than $25 and it includes 36 inches by 25 feet of screen material, 60 feet of spline, and one roller. Here is the link for your reference:

  1. Remove the insect screen by pulling up the lift tab and then pulling the screen panel towards you.

  2. Stick in the screwdriver in the corner where the spline is free and use it as leverage to yank out the old spline. You might need a pair of pliers to pull it out if it’s stubborn. Mine had over 20 years of grime and nasty build up so it was encrusted in the groove.

    Remove old spline from window screen panel.

  3. If you can’t reuse your old spline, cut a new piece that fits your screen by using the old spline as your measuring guide. Consider cutting an extra inch because sometimes as you insert the spline, you will notice the spline will be used up more than you expected.

    Remove old insect screen. Beware! Lots of dirt may come out as you pull it out.

  4. Cut a piece of the insect screen material that fits your window screen and add an inch on all sides as a precaution. You can trim it easily after you install it.
  5. Place the spline over the border of the window screen and use the roller to insert the spline into the window screen groove. Make sure the insect screen is aligned properly and has a tight feel but not too tight because you might end ripping it as you insert the spline into the groove.

    Don’t forget to put back the lift tab.

  8. Now you are ready to put the window insect screen back! First, insert the top then once it feels properly aligned push the screen down. You might have to use the lift tab to align it properly until you are happy with the fit.

Super easy to replace, right? Now you can open your windows again without worrying about insects coming in through the window!

PS: I will continue with the remaining 10 days of Taiwan, Hong Kong, and China but I want to move on to catch up with the past couple of months of DIY projects : )

  1. Here is a tip – if the screen frames are old, the inside edge of the “slot” will probably be rough due to a combination of corrosion and mesh imprint. This will act as a serrated edge and the screen will tear as it is pushed in. The only solution is to sand until smooth again.
