A exhaust fan seal is a gasket that fits between the fan housing and the ceiling or wall. It helps to prevent air leaks, which can reduce the fan’s effectiveness and lead to increased energy consumption. Here are the steps to install an exhaust fan seal –

Step 1: Gather the Required Tools

Before you start, you’ll need to gather some tools to make the installation process easier. Here’s a list of the items you’ll need:


The installation of an Exhaust Fan Seal should be carried out by a registered electrician

Please note, the below is a guide only to provide the consumer with insight into how the exhaust fan seal installation is carried out.

  • A ladder or step stool
  • A utility knife
  • A caulk gun
  • Caulk (preferably silicone)
  • The exhaust fan seal kit

Step 2: Turn off the Power

Before starting the installation process, turn off the power to the fan. You can do this by switching off the circuit breaker or unplugging the fan.

Step 3: Remove the Old Gasket

If your fan already has a gasket in place, you’ll need to remove it. Use a utility knife to carefully cut away the old gasket, making sure not to damage the fan housing or the ceiling.

Step 4: Prepare the Surface

Clean the surface of the fan housing and the ceiling or wall where the gasket will be installed. Remove any debris, dust, or old caulking.

Step 5: Apply the Caulk

Using the caulk gun, apply a generous amount of silicone caulk around the perimeter of the fan housing. Make sure to create a continuous bead of caulk to ensure that the gasket adheres correctly.

Step 6: Install the Gasket

Place the exhaust fan seal onto the fan housing, making sure that it is positioned correctly. Gently press down on the gasket, ensuring that it adheres to the caulk.

Step 7: Secure the Gasket

Use a utility knife to carefully trim any excess caulk around the gasket. This will give the installation a neat and professional appearance.

Step 8: Turn on the Power

After the installation is complete, turn on the power to the fan to ensure that it is working correctly. Test the fan to make sure that it is properly ventilating the room.

Benefits of Installing Exhaust Fan Seals under VEU Program

The Victorian Energy Upgrades (VEU) program is an energy efficiency scheme in Victoria, Australia, that aims to reduce energy consumption and greenhouse gas emissions by providing incentives for energy-efficient upgrades. Installing exhaust fan seals under the VEU program can provide several benefits, including:

  • Reduced Energy Bills: An exhaust fan seal can prevent air leaks, which reduces the amount of conditioned air that escapes from your home. This means that your heating and cooling systems won’t have to work as hard to maintain a comfortable temperature, which can lead to lower energy bills.
  • Improved Indoor Air Quality: An exhaust fan seal helps to prevent moisture and odors from escaping into your home’s walls and ceiling, reducing the risk of mold and mildew growth. This can improve your home’s indoor air quality, which is especially important for people with allergies or respiratory problems.
  • Increased Comfort: Air leaks can cause drafts and temperature fluctuations, leading to discomfort and reduced quality of life. By preventing air leaks, an exhaust fan seal can help to create a more comfortable living environment.
  • Incentives and Rebates: Under the VEU program, households and businesses that install energy-efficient upgrades, such as exhaust fan seals, for FREE to offset the cost of the upgrade.
  • Environmental Benefits: By reducing energy consumption, exhaust fan seals help to reduce greenhouse gas emissions and protect the environment. Installing exhaust fan seals under the VEU program can help to support Victoria’s goal of achieving net-zero emissions by 2050.
