Leaks around your windows and doors cost you a significant amount of money in wasted energy costs. Not only that, but water can enter these leaky areas and start to rot your windows and doors. Detecting leaks is not always easy, especially if they are particularly small. If you’re wondering about your home’s windows and doors and want to make sure that they’re not costing you through leaks, there are a few things you can do to check your home carefully.

Testing Your Home for Air Leaks

To test your home for air leaks, follow these steps:

Step 1 – Seal the House

The first step in checking for leaks is to seal up the house. Lock the doors, windows, and skylights, and close the dampers and vents. This will ensure you don’t have signs of a leak simply due to something that’s not shut completely.

Step 2 – Turn on Fans

Next, turn on the kitchen and bath exhaust fans, but not the ceiling fans. This will create airflow in a vacuum.

Step 3 – Inspect

Grab an incense stick or something else that safely creates smoke. Walk around your home, passing the stick along each window and door frame. Watch the smoke to see if it is moving to indicate an air leak.

Finding Problems With Windows

If you identify a leak near a window, you’ll need to look a little more closely to find the exact cause. Shake the window gently, and if it rattles, then you have a frame that’s not secure. Look around the edge of the window to see if there are any gaps. Look for cracks, and make sure the windows have no problems with the locking mechanism or the opening and closing mechanisms.

Finding Problems With Doors

If you noticed leaks around a door, check it carefully. Look for cracks, which can allow air to seep through. Make sure the weatherstripping is in good repair and has no gaps. Check the hinges to make sure they are tight and the door fits properly in the threshold.

Finding Problems With Skylights

Finally, check your skylights, if your home has any. This will require carefully accessing your roof. Check the seams between the flashing or shingles to ensure there are no gaps. Check for debris around the skylight that could be allowing water to pool. Finally, go back inside your home and look for brown stains on the walls around the skylight. This indicates a water leak, which will allow air out and put the integrity of your roof at risk.

If you’re noticing these signs of leaks, you may need to replace the windows or doors. Zen Windows offers exceptional products in Charlotte and Greensboro, giving you back a leak-free home.
