Tips for Finding Air Leaks Around Your Windows | Billy.com

Are you tired of high heating bills during the winter months? The cold air creeping into your home can make your heating system work overtime, resulting in increased energy consumption and expenses. Poor insulation or air leaks around your windows are often the culprits behind that cold draft you feel in your living room. However, finding these air leaks is often difficult. We have some tips for finding air leaks around your windows below so that you know where to start when you’re trying to fix them.

Complete a Visual Inspection

Before you call a window pro about an air leak or attempt to fix it yourself, it’s important to identify the area where you believe the air leak is. Start with a visual inspection of your windows, both from inside and outside your home. Look for any visible gaps, cracks, or holes around the window frames or between the windows and the walls. Pay attention to the corners, sills, and frames, as these areas are more prone to air leaks.

Try the Candle Test

If you want to take your inspection to the next level, try the candle test. Close all your windows and doors, and turn off all fans and air circulation devices. Light a candle or a stick of incense, and walk slowly around each of your windows, holding the flame or the smoke near the frame and the sill. If you notice that the flame flickers or the smoke is drawn into any specific area, that indicates an air leak. Mark that area with a piece of masking tape or a sticky note.

Add Weatherstripping, Caulking, or Insulation Film

Now that you have identified the air leaks around your windows, it’s time to seal those gaps and cracks. One of the most popular and cost-effective options is to add weatherstripping, caulking, or insulation film—or any combination. These are some of the best DIY solutions for sealing your windows and doors you can try before contacting a professional for additional assistance.

Weatherstripping

Weatherstripping is a flexible material that you or a professional can apply around the window frames and sills to fill in any gaps and prevent drafts. There are several types of weatherstripping materials, including adhesive foam strips, V-strips, and felt strips, among others. Make sure to choose a weatherstripping material that fits tightly and securely around your windows.

Caulking

Another effective sealing method is caulking. Caulk is a waterproof substance that you can apply around the window frames to seal it shut and prevent air leaks. It’s ideal for sealing small gaps and cracks that weatherstripping can’t fix. One of the best tips for weatherproofing your windows is to find the right caulk for your purpose and environment.

Insulation Film

If you want to take energy efficiency to the next level, consider installing window insulation film. Window insulation film is a transparent, lightweight plastic sheet that you can apply to your windows to create a barrier between your home and the outside cold air.

Finding and sealing air leaks around your windows is an easy and cost-effective way to save energy and money on your heating bills. If your window needs additional repair, not just additional weatherstripping or other options, contact a trusted professional in your area.
