Whether you’re a seasoned DIY enthusiast or a novice, this guide will help equip you with the knowledge and skills to tackle this project confidently.
Step 1: Assessing Your Garage’s Ventilation Needs
Before diving into the installation process, assessing your garage’s ventilation requirements is crucial. Consider factors such as the size of your garage, the type of activities performed inside, and any existing ventilation systems. This initial evaluation will help determine the appropriate size and capacity of the exhaust fan needed to ventilate your space effectively.
Choosing the Right Exhaust Fan
Selecting the right exhaust fan is paramount to achieving optimal ventilation in your garage. Look for a fan specifically designed for garage environments, with features such as high airflow capacity, durable construction, and energy efficiency.

Step 2: Gather your tools
The following materials will be needed for garage exhaust fan installation:
- Mounting bolts and screws
- Sealant or Caulk
- Regular Screwdriver Set
- Wireless switch
- Shutter vent
- Flashing tape
- Siding removal tool
Step 3: Preparing Your Garage for Installation
Prepare your garage for the installation by clearing out any clutter and ensuring a clean and accessible workspace. Locate the ideal spot for mounting the exhaust fan, taking into account factors such as proximity to electrical outlets and optimal airflow. Mark the mounting location and ensure it’s free from any obstructions.
Step 4: Cut a Hole & Seal the Edges
Once you have decided where to install your fan, cut a 14″ x 14″ hole in the area.
The next step is to seal the hole’s top and bottom edges with Sealant or Caulk.

Make sure you do not leave any insulation in the hole, as it may cause a fire. Then, cut two 2x4s and insert them into the top and bottom. Use pocket hole screws to attach them to the wall studs.
The 2x4s can be made easier to maneuver by putting temporary hooks on them.
Here is a picture of the 2x4s sealed into the bottom of the hole:
Step 5: Construct A Vent Frame (J Channel Frame)
After cutting a hole in the wall, make sure that the exterior side is waterproof. To prevent water from penetrating the siding, J channels need to be installed. A frame can be built around the vent, overlapping the siding and protecting the edges. The following picture shows four pieces of J channel cut to create the vent frame:
Make a square by cutting the pieces to size and nailing the ends together.
Step 6: Preparing The Sidings
The exterior vent must be installed under the siding, which requires several pieces of siding to be removed. A siding removal tool makes it easy to remove siding from walls.

As a result, you will be able to continue working on the hole. You will need to seal the hole’s edges with some flashing tape to waterproof it.
Step 7: Construct A J Channel Frame For The Garage Vent
The shutter vent should then be inserted and nailed to the wall studs. You can buy a shutter vent separately if your model does not come with one.

After that, attach the J channel frame.
This is how the vent will look from the inside:
Step 8: Construct A Wooden Frame Spacer To Install The Exhaust Fan
You will then need to construct a framed wooden spacer for the garage wall exhaust fan.
The exhaust fan will need enough distance from the hole for the shutters to function properly, so you’ll need to build a 2x4s wooden frame between the wall and the fan.
Use the miter saw to cut some 2x4s to length. Using pocket hole screws, attach them to form a frame.
Below is an image of the garage wall exhaust fan frame:
Finally, the exhaust fan is mounted on the wall. Attach the fan to the 2x4s frame and make sure the shutters open and close freely. Use heavy-duty screws to attach the fan to the 2x4s frame. The picture below shows a mounted garage wall exhaust fan (powered on) from the inside:
