How to Seal Windows

Are all the windows in your home properly sealed? Are you 100% sure about that? The truth is that it’s rare for a person to actually feel leaks simply by walking around their home. If you think that if you can’t feel it and there’s no harm done, think again. Drafty windows mean uneven temperatures in your home and an HVAC that works harder to cool or heat the house. The result: skyrocketing energy bills.

If you’re not sure how to find out whether you need to seal your windows, you’ve come to the right place.

How to Check For Drafts

If we’re having a particularly chilly winter, you may be able to feel colder air while walking by your windows. However, during mild and moderate temperatures, you’ll have to be proactive to find these leaks.

To do so, place the palms of your hands around the window frames. If you can feel some air coming in, you have your answer. If you need more of a visual reassurance, hold a lighter or a candle around the window. If the flame flickers, you most definitely need to seal the area around the windows.

How to Seal Window Frames in 5 Steps

Step 1. Get the right tools

You’ll need caulk softener, a putty knife, a cleaning rag, a dry towel, window glazing, and new caulk.

Step 2. Scrape off old caulk

Do this by using the putty knife. If nothing’s coming off, you can use caulk remover (available at any hardware store). Apply it around the window frame and let it sit for several hours. A minimum of two hours should work, but if you’re still having a hard time, leave the softener on overnight.

Step 3. Wipe off the frame’s surface

Use a damp cleaning rag to get rid of old caulk flakes and dust, then use a towel to dry up the window frames. They will need to be fully dry for the new caulk to set properly.

Step 4. Spread new glazing around the frames

Using the putty knife, spread a new layer of glazing around the window frame.

Step 5. Apply new caulk

Cut off the tip of the caulk tube at a 45-degree angle for easier application. Use an entire tube for each window. Allow for about 15 hours for the new caulk to fully dry.
