Living in Ottawa, Canada, you know how essential it is to insulate your home correctly. You want your home to be comfortable during the cold winter and hot summer days. But sometimes, you might feel a draught or notice higher energy bills. These could be signs of air leaks around your windows. Fixing window air leaks is essential for keeping your house cozy and energy-efficient. Let’s dive into understanding how to fix window air leaks.
What Are Window Air Leaks?
Window air leaks happen when there are small gaps or cracks around your windows. These gaps let cold or hot air enter your house, making it uncomfortable and causing your heating or cooling system to work harder.
Why Should You Fix Window Air Leaks?
Fixing window air leaks can offer several benefits:
– Lower Energy Bills: Properly sealed windows ensure that your heating and cooling systems work efficiently, saving you money.
– Comfort: No more cold draughts in winter or hot spots in summer.
– Extended Lifespan of HVAC Systems: When your heating and cooling systems don’t have to work as hard, they last longer.
– Environmental Benefit: Reduced energy use also means a smaller carbon footprint.
How to Identify Window Air Leaks
Before fixing window air leaks, you need to find them. Here are some simple ways to identify where air leaks are happening:
Visual Inspection
Look for gaps and cracks around your window frames. You might also see old, worn-out caulking or weatherstripping that needs replacing.
Paper Test
Close your window on a piece of paper. Try to pull the paper out. If it slides out easily, there is a gap and an air leak.
Candle Test
To perform a candle test, you need to hold a lit candle near the window edges on a windy day. You can also use incense stick instead of a candle. If the flame or smoke moves, there’s a leak.

Step-by-Step Guide to Fixing Window Air Leaks
- Caulking
Caulking is one of the simplest ways to seal window air leaks. Here’s how to do it:
– Step 1: Clean the area around the window where you apply the caulk. Remove any old caulking using a putty knife.
– Step 2: Load your caulk gun with a tube of caulk.
– Step 3: Hold the caulk gun at a 45-degree angle and apply a steady stream of caulk along the edge of the window frame.
– Step 4: Smooth the caulk with your finger or a caulk-smoothing tool.
– Step 5: Let the caulk dry per the manufacturer’s instructions.
- Weatherstripping
Weatherstripping is another effective method to fix window air leaks.
– Step 1: Clean the window sash and frame.
– Step 2: Measure the window length where you will apply the weatherstripping.
– Step 3: Cut the weatherstripping to the measured length.
– Step 4: Peel away the backing and press the weatherstripping into place along the edges of the window.
- Foam Sealant
For larger gaps, you might need foam sealant:
– Step 1: Clean the area where you will apply the foam.
– Step 2: Shake the can of foam sealant well.
– Step 3: Insert the can’s nozzle into the gap and press the trigger. Fill the gap carefully as the foam expands.
– Step 4: Let the foam dry thoroughly, then trim the excess with a utility knife.
- Window Film
In addition to caulking, weatherstripping, and foam sealant, window film can offer added insulation.
– Step 1: Clean the window glass.
– Step 2: Cut the film to the size of the window.
– Step 3: Use double-sided tape to attach the film to the window frame.
– Step 4: Use a hair dryer to shrink the film and remove wrinkles.
Preventative Measures
Fixing air leaks is essential, but it is also good to take preventative measures:
– Regular Inspections: Inspect your windows annually for any gaps or cracks.
– Maintain Caulking and Weatherstripping: Keep an eye on the caulking and weatherstripping. Replace them if they wear out.
– Consider Storm Windows: If you live in an area with extreme weather, installing storm windows can help provide an extra layer of protection against air leaks.
