Dryer vents are an important part of any household. They help to prevent fires and keep your clothes from getting musty. The problem is that they can get clogged up with lint, which can cause problems for your dryer and, even worse, your home.
A dryer vent flap is often overlooked when it comes to the safety of our homes. It is not a glamorous appliance, but it does provide a necessary function.
The purpose of the dryer vent flap is to keep heat and moisture from escaping out of the dryer’s exhaust pipe and entering your home. This can cause mold and mildew to grow in your dryer, which can lead to respiratory problems for you and your family.
A dryer vent flap will eventually wear out, so it’s important to know how to replace one!

- Use a utility knife to remove the old material, then seal it again with latex caulk.
- Ensure that the vent flushes against your siding and that it is held in place as you apply the new bead.

How Does A Dryer Vent Flap Actually Work?
Hot air is used in dryers to spin the clothes in, producing little bits of fabric or lint that quickly develop.
This debris and the extra air pass via a connected exhaust vent pipe that exits the building. The final door is the dryer vent flap door.
When everything is in order, this portion automatically opens while the dryer produces air during one of its cycles and remains closed when the dryer is not in use.
The lint filter in your dryer needs to be cleaned every few uses since lint builds over time.
The dryer may not function properly if there is too much lint present.
It can also jam the vent pipe, making it impossible for the dryer vent flaps to open and creating a far worse problem than if the filter wasn’t cleaned frequently.
5 Tips To Maintain Your Outside Dryer Vent
To improve the airflow in your dryer, the exterior dryer vent needs to be cleaned and inspected every three months.
This will shorten the time it takes for the laundry to dry and aid in keeping your home dry as well.
- While the dryer is operating, check the outside vent to make sure the flaps are moving freely. Turn off the dryer and manually open the vents if they are not functioning properly.
- Check the hinges for rust and give them a mild lubrication.
- Additionally, look for any fractures or components missing from the vent.
- Use your hands or a long-handled wire brush to get rid of obstructing lint. Regular cleaning is crucial in humid locations, where moisture can cause lint to form and stick to the vent, leading it to malfunction.
- Clean the vent cover with a brush or an old cloth if it is covered in dust and grime by mixing a few drops of dish soap in warm water. Then rinse thoroughly with fresh water and let it dry.

FAQ
What is a dryer vent flap?
A door flap at the end of the vent pipe opens automatically when your dryer is producing air and should close firmly when the dryer is turned off.
A lint building can prevent the door flap from closing smoothly, allowing pests and chilly or heated air into your house.
Can you replace the flaps on a dryer vent?
Yes, you can replace the flap if it doesn’t close. It just costs $5 at home improvement stores.
Can duct tape be used on dryer vent?
NEVER attach venting materials using duct tape. Over time, the glue dries out, especially in response to temperature fluctuations, leaving holes in the vent’s joints.
Should dryer vent flap be open?
To allow hot air to circulate out of the dryer and prevent overheating, the vent flap protecting the dryer vent should always be opened while the dryer is operating.
Can I put silicone around a dryer vent?
According to the Centers for Disease Control and Prevention, silicone caulk or spray foam work best for closing dryer vent gaps because they offer a strong seal that keeps out pests and prevents air penetration.
How often should you change your dryer vent hose?
It is always a good idea to have a professional inspect and clean your dryer exhaust vents at least once a year.
However, you might want to think about extending that frequency to every six months if your home uses the dryer frequently, like one with lots of kids.
