Why May You Want to Reroute the Dryer Vent From the Garage to Outside?

1 . To Prevent Moisture Buildup

One of the main reasons to reroute your dryer vent from the garage to outside is to avoid any potential moisture buildup. When a dryer is running, it releases hot air and moisture which can lead to condensation in an enclosed space like a garage.

This can cause mold, mildew or even damage to your walls and belongings. By rerouting the vent to the outside, you can effectively remove this excess moisture and prevent any potential damage.

2 . To Improve Indoor Air Quality

Another important reason to reroute your dryer vent is to improve the indoor air quality in your garage. The hot, damp air released by a dryer can contain harmful pollutants and allergens that can be trapped in an enclosed space.

By venting the air outside, you can reduce the concentration of these pollutants and improve the overall air quality in your garage.

3 . To Avoid Fire Hazards

Improperly vented dryers can also pose a fire hazard. If lint and debris build up in the dryer vent, it can become clogged and cause overheating which can lead to a fire. By rerouting the vent to the outside, you can reduce the risk of this happening and ensure your home stays safe.

4 . To Comply With Building Codes

In some areas, it may be required by building codes to have dryer vents routed to the outside. This is for safety reasons and to prevent any potential hazards. If you are renovating your home or selling it, it is important to check with local building codes and regulations to ensure you comply.

5 . To Save Energy and Money

Lastly, rerouting your dryer vent to the outside can also save you energy and money. When a dryer is not properly vented, it has to work harder and use more energy to dry clothes. By venting the hot air outside, your dryer can operate more efficiently and reduce energy consumption, ultimately saving you money on utility bills.

How to Reroute Dryer Vent From Garage to Outside in 6 Easy Steps

Now that you understand why it is important to reroute your dryer vent, here are some steps to guide you through the process:

Step 1: Gather the Necessary Tools and Materials

The first step to rerouting your dryer vent is to gather all the necessary tools and materials. These may include a drill, screws, duct tape, aluminum foil tape, a new vent hood, and new flexible ducting. Also, make sure to have a measuring tape and a pencil on hand to accurately mark the measurements for cutting.

Step 2: Locate the Ideal Spot for Your New Vent

Before you start any work, it is important to choose the ideal spot for your new vent. This should be a place outside of your garage that is away from any windows or doors. It should also be at a safe distance from any outdoor vents or air conditioning units.

Step 3: Measure and Cut the Vent Hole

Using your measuring tape and pencil, mark the measurements for cutting the vent hole. Make sure to leave enough space for the vent hood to fit snugly. Once marked, use a drill to create a pilot hole and then cut out the vent hole using a jigsaw.

Step 5: Connect the Flexible Ducting

Next, connect the flexible ducting to the vent hood using screws and seal it with aluminum foil tape. The other end of the ducting should be connected to your dryer’s exhaust pipe.

Step 6: Test and Secure Everything in Place

Once you have completed all the steps, it is important to test everything to ensure that it is functioning properly. Turn on your dryer and check for any air leaks or loose connections. Once everything is secure, you can then permanently fasten the ducting in place using screws.

Some Extra Tips to Reroute Dryer Vent From Garage to Outside

1 . Do Not Use PVC Pipes

If you are planning to reroute your dryer vent from the garage to outside, it is important to use the right materials. While PVC pipes may seem like a cost-effective option, they are not suitable for this purpose.

Planning to Reroute Your Dryer Vent

The hot air and lint from your dryer can cause PVC pipes to melt or warp, leading to potential fire hazards. Instead, opt for aluminum or galvanized steel pipes that are specifically designed for dryer vents.

2. Check Your Local Codes

Before starting the rerouting process, make sure to check your local building codes and regulations. Some areas may have specific requirements for venting dryers outside, such as the minimum distance from windows and doors. It is important to comply with these codes to ensure the safety of your home and avoid any potential fines.

3. Consider Hiring a Professional

If you are not confident in your DIY skills or if the rerouting process seems too complex, consider hiring a professional to do the job for you. They have the necessary expertise and equipment to ensure that the dryer vent is properly installed and meets all safety standards.

4. Regularly Clean and Inspect the Vent

Once the dryer vent has been rerouted, it is crucial to regularly clean and inspect it. Lint buildup can occur over time, which can not only decrease the efficiency of your dryer but also increase the risk of fire.

Make sure to clean the lint trap after each use and schedule a professional cleaning at least once a year. Additionally, inspect the vent for any damage or blockages that may occur.

5. Consider Installing a Dryer Vent Cover

To prevent pests and insects from entering your home through the dryer vent, consider installing a dryer vent cover. These covers are easy to install and can also help keep out leaves and debris that may clog the vent.
