How to Find, Seal, and Prevent Air Leaks In Your Property


Air leaks can be a big problem in your home, making it harder to heat and cool your house and leading to higher energy bills. Fortunately, there are a few things you can do to find and seal air leaks.

Where Air Leaks Most Occur

Air leaks can occur in all sorts of places, but there are some areas where they are more common. Places where different materials meet, such as around windows and doors, are often the main culprits. Recessed lights and electrical outlets, cable TV and phone jacks, plumbing pipes, and vents are other places to check.

Other areas where air leak occurs: 

  • Attic hatches
  • Ceiling fixtures
  • Baseboards
  • Weatherstripping

How to Find Air Leaks

Before you can fix air leaks, you need to find them. You can use a candle or incense stick to help you find the leaks; hold the lighted candle or stick close to the suspected area and watch the smoke. If the smoke is blown away or sucked into the building, there is an air leak. 

You can also use a spray bottle of soapy water to help you find the leaks. Spray a thin layer of soapy water around the area and watch for bubbles, indicating the presence of a leak.

You can also use a blower door. This device is placed over an exterior door and uses a fan to create negative pressure in the house. It causes air to leak from all the places where there are air leaks. Once the blower door is in place, you can walk around the house and see where the air is coming in.

How to Seal Air Leaks

Once you have found the air leaks in your home, you need to seal them. There are several ways to do this, depending on the size and location of the leak. For small leaks, you can use caulk or weatherstripping. 

Caulk is a sealant that is applied to the joint between two surfaces. It is available in a variety of colors and can be used to seal leaks around windows, doors, and other openings. 

On the other hand, weatherstripping is a material that is installed around the edges of doors and windows to create a seal.

For larger leaks, you can use foam insulation or sheet metal. Foam insulation is a material that is sprayed or injected into the opening to seal it. Sheet metal is a material that is installed over the opening to create a seal.

How to Prevent Air Leaks

There are a number of ways to prevent air leaks in your home. The best way to prevent air leaks is to seal them with caulk, weatherstripping, foam insulation, or sheet metal. 

You can also improve the insulation in your home to help keep the heat in during the winter and the cool air in during the summer. Or, you can install storm windows and doors to help keep the weather out.

To Sum Up

In conclusion, finding and sealing air leaks in your house is important to improve your home’s energy efficiency and comfort. There are a few ways to identify air leaks, such as using a candle, incense stick, or a blower door test. Once you have identified the location of the air leaks, you can seal them with various materials, such as weatherstripping, caulk, or spray foam.
