How to Replace A Dryer Vent Hose Inside A Wall?

If you are looking for how to replace a dryer vent hose inside a wall, here are step-by-step steps to walk you through the entire process. Also known as a dryer duct, a dryer vent is a key to the proper operation of your dryer. Without it, your dryer cannot efficiently dry your clothes in addition to fire hazards.

By properly installing a dryer vent, regularly maintaining it, and troubleshooting small problems, your dryer will function just fine. One of the most important components of a dryer is its vent hose and when it gets damaged, it can lead to an accumulation of lint inside the dryer. Lint is known for being one of the most common igniters of dryer fires.

When this hose is damaged, it can cause the dryer to not work properly and may take longer to dry your clothes, thus increasing your utility bills. Luckily, this problem can be solved by replacing the dryer vent hose.

Generally, many people prefer rigid metal vents over plastic and other types of metals because they are way safer. Flexible plastics tend to build up more lint, retard airflow and require regular cleaning. Additionally, flexible plastic vents tend to crush easily, this blocking airflow and causing your dryer to overheat, which can cause lint fires.

Gather all required materials to replace a dryer vent hose inside a wall

The first step for any handyman project is gathering the materials necessary for the project. You want to have the right kind of equipment and materials at hand to avoid making trips to the store during the project. Whether you are a DIY enthusiast or a professional plumber, the success of your project depends on the types of tools you have.

This is a quiet and easy task, especially if you have every material needed for the job.
To make your job easier, here is a list of the basic materials you should have in place in order to replace a dryer vent hose inside a wall.

Before we get started, make sure you have at least the above materials. Measure the size of your vent hose and then order a little longer for adjustment. In the case of a small space, the exhaust pipe of the dryer joins the periscope/ offset duct that links the duct to the wall.

Step-by-Step Guide on How to Replace A Dryer Vent Hose Inside A Wall

Go through our step-by-step guide to learn how to replace a dryer vent hose inside a wall:

Step #1: Prep working station

Once you have the basic list of required materials, you can now begin to replace the old vent hose. But before that, make sure you turn off any electric switches for your own safety.

Unplug your dryer and move it away from the wall to have enough room to maneuver while working as well as for easy access to the hose.

Step #2: Remove the old vent from the hose

Remove the ring clamp securing the vent hose and detach the vent from the vent hose on the wall. Use your flathead screwdriver or socket driver to easily loosen the brackets. You want to use a wrench because of its versatility since you can adjust the side of its jaw depending on the diameter of the screw.

Step #3: Loosen the exterior exhaust outside the house

Next, locate the external vent exhaust and unbolt the cover to remove it. You will find a buildup of lint inside this exhaust. Push it a little inside to detach it from the wall completely.

Once you have removed the old vent hose, you now have a hole on the wall that needs to be cleaned. Use your vent brush to thoroughly clean this area to remove any debris before you proceed.

You can use a stud or buffer before you install the new vent hose to ensure that the dryer vent stays firm after installation.

Secure sheets of plywood to the wall using screws to create a buffer to ensure the vent does not move an inch once you have installed it.

Next, push the new vent duct and join it with the exhaust outlet. You want to make sure the new duct and the old duct are the same sizes to avoid mishaps when installing. Also, push the new duct gradually inside the wall and bolt it tightly. In case the vent juts from the wall, use your tin snips to resize it.

Step #4: Re-fix the exhaust duct to the offset pipe

Clean the exhaust duct comprehensively before re-attaching it to the offset pipe. Use your vacuum cleaner to get rid of the buildup lint and then attach the exhaust duct to the pipe using a ring clamp. Make sure it is secured properly to prevent air or lint from escaping. Seal off any hole between the duct and the concrete wall using caulk or aluminum foil tape. Avoid using standard tape because it can dry quickly.

Step #5: Secure the offset pipe using screws

Go outside to screw back the duct to secure its hood and finish your replacement process.

Step #6: Return your dryer to the wall

Last but not least, push your dry back to the wall and reconnect the power. Test whether your job has been successful by turning the dryer on. Check if the dryer is producing air through the pipe on the outside.
