Your dryer vent should always vent to the outside, as this helps to prevent the buildup of lint and moisture, which can lead to fires. If your dryer vent is currently venting into your garage, you may be wondering how to reroute the dryer vent from the garage to the outside. 

Don’t worry. In this comprehensive blog post, we’re going to show you exactly how to reroute your dryer vent from the garage to the outside. Having a properly routed dryer vent is crucial for the safety and efficiency of your dryer, as it expels hot air and moisture from your home. 

So, let’s get started on learning how to reroute your dryer vent from the garage to the outside!

Reasons Not to Vent Your Dryer into the Garage

Before we dive into the specifics of rerouting your dryer vent, let’s understand the reasons why you should avoid venting your dryer into the garage.

Violation of Building Codes

Violation of Building Codes

The dryer vent into the garage goes against building codes, like the International Residential Code (IRC), which requires exhaust ducts to exit outside. This can lead to fines and make it difficult to sell your home.

Carbon Monoxide Poisoning

If your dryer uses gas, venting it into the garage can release harmful carbon monoxide, which causes health issues and even be fatal in high concentrations.

Mold Growth

Venting hot, humid air into the garage creates an environment conducive to mold growth. Mold not only produces foul odors but can also pose health risks and cause allergies.

Risk of Fire 

Lint from the dryer can accumulate in the garage and become highly flammable. This expands the risk of fires, especially if exposed wires or other ignition sources are present. Based on the United States Fire Administration, there are 2,900 home fires annually caused by dryers. 

Structural Damage 

The high humidity levels caused by venting your dryer into the garage can damage timber and rust metal and reduce insulation efficiency. This leads to higher energy bills and potential damage to cars or machinery.

Respiratory Issues

Inhaling lint particles emitted from the dryer vent can cause respiratory problems, including allergies and irritation.

Steps on How to Reroute Dryer Vent From Garage to Outside

So, if your dryer vent is installed in the garage, you’ll need a few tools and materials to successfully reroute your dryer vent from the garage to the outside. Here’s a list of what you’ll require:

Tools and Materials You’ll Need

1. Vent Duct: Choose a rigid metal duct, such as aluminum, for durability and fire safety.

2. Vent Hood: This is the exterior component that allows air to exit while preventing pests and debris from entering.

3. Screwdriver or Drill: For removing and securing duct connections.

4. Metal Snips: To cut the duct to the desired length.

5. Tape Measure: To accurately measure the required length of the vent duct.

6. Duct Clamps: These are used to secure the connections between duct pieces.

7. Safety Goggles and Gloves: To protect yourself during the installation process.

8. Ladder: If you need to access a high exterior wall for vent installation.

Step-by-Step Guide to Rerouting Your Dryer Vent

Now that you have the necessary tools and materials let’s walk through the process of rerouting dryer vents out of a garage.

Step 1: Mark and Drill the Pilot Hole

Mark and Drill the Pilot Hole

1. Identify the location where you want the vent to be on the wall.

2. Mark the center of the hole where you will drill the pilot hole.

3. Measure the diameter of your vent and use this measurement to mark the circumference around the pilot hole where the vent will be installed.

4. Dig a pilot hole from the interior of your house to the exterior using a suitable drill bit.

Step 2: Drill the Vent Hole Through the Wall

Drill the Vent Hole Through the Wall

1. Go outside and locate the pilot hole you drilled from the interior.

2. Mark the circumference on the exterior wall where you will install the vent.

3. Drill slightly into the wall along the marked circumference.

4. Use a hammer and chisel to carefully knock out the bricks or other materials inside the marked circumference, creating a hole the size of your vent through the wall.

Step 3: Install Your Outer Vent

Install Your Outer Vent

1. Purchase an appropriate vent cover for exterior use. You can find these vent covers on websites like Amazon. 

2. Position the outer vent cover over the hole you created on the exterior wall and ensure it is level.

3. Use a 3/16-inch drill bit to create holes in each corner of the vent cover where you will attach screws.

4. Place screws into the holes and tighten them to secure the vent cover in place.

5. Use caulk around the edges of the vent cover to seal any gaps, preventing water from seeping into your vent.

Step 4: Install the Aluminum Vent Hose

Install the Aluminum Vent Hose

1. Purchase a suitable aluminum vent hose, which you can find in dryer vent kits available on websites like Amazon.

2. Go back inside the house and connect one end of the aluminum hose to the vent installed on the exterior wall.

3. Use a clamp to secure the hose and the vent together. Tighten the clamp by using a 5/16-inch drill bit or a regular screwdriver to ensure a snug fit.

4. Slide the other end of the aluminum hose onto the dryer vent outlet and secure it with another clamp.

5. Tighten the clamp to ensure a secure connection between the hose and the dryer vent outlet.

6. Apply caulk around the point where the aluminum hose joins the dryer vent outlet to seal any gaps and prevent air leaks.

By following these steps, you can successfully reroute your dryer vent through the wall to the outside. It’s important to ensure proper installation and secure connections to maintain the safety and efficiency of your dryer system.
