In many cases, you can resolve the problem yourself without the help of a professional. The following tips will help you locate air leaks in your home and seal them.
- Finding the Air Leak: Check the most common areas first including around your doors and windows as well as the foundation to leaks. For your doors and windows, pay attention to the weather stripping and check to see if there is extra space in the frames. You should also check the following for air leaks:
- Confirming the Leak: If you believe you have found an air leak, you can confirm this by lighting an incense stick or candle near the suspected leak. The smoke will either escape the area through the leak or get blown back into the space.
- Seal Cracks with Caulk: You can seal cracks that are smaller than ¼ of an inch wide with caulk. If you need to caulk in an area exposed to extreme heat, use caulk that can handle the high temperature.
- Seal Cracks with Foam Sealant: For cracks that are between ¼ of an inch and 3 inches in width, use foam sealant to seal them.
- Install New Weather Stripping: If the weather stripping around your doors and windows does not seal properly, replace it with new weather stripping. Check the hinges on your doors as well because loose hinges could cause air to escape.
