Leaking Dryer Vent

A leaking dryer vent may cause mildew and mold in your home. Severe cases might even cause water damage. The internet is flooded with DIY or “do it yourself” tips for how to replace dryer vent systems, but failure to call a professional could make the problem even worse. Improper dryer vent installation can cause home damage and health problems, and it’s just not worth the risk. The first step toward installing a dryer vent is understanding the potential reasons for a leak.

Dryer Vent Leaks

Top Causes of a Leaking Dryer Vent

Condensation on the Pipe

There’s a certain amount of water in the air, which manifests as humidity. When there’s a large temperature difference between an object and the air around it, this water vapor condenses into a liquid form on the surface of that object. Condensation may occur on a dryer vent since it expels the hot air it uses to dry your clothes. The vent pipe then begins to drip water, which you want to avoid. You can alleviate this problem with proper insulation along the length of the pipe.

Broken Vent Flapper

The vent opening on the outside of your home that connects to the dryer is where the hot air from the machine is let out. The flapper is the cover that goes on top of this opening to protect it. When the air from your dryer is expelled, the flapper opens. However, a broken flapper may become stuck in an open position, allowing rain and snow to enter the vent. With all the excess water that gathers, the vent pipe can develop openings and begin to leak.

Dust and Lint Obstruction

An unclean vent may become backed up with lint, dust, and debris, which limits the passage of air and water vapor through the pipe. Since it cannot properly disperse into the air, the moisture condenses in the dryer pipe and eventually leads to visible leakage. You must clear out the vent so that it functions without any interference to reverse this effect. Doing so may be difficult without the right experience or tools, however, so call a vent cleaning service in your area if you need help.

Health Effects of Leaking Vents

Leaking vents can cause mold, mildew, and dust to build up in the house. This might agitate respiratory issues or allergies, and can even lead to certain types of cancers. Gas dryers may leak carbon monoxide into your home if they’re not properly ventilated. Carbon monoxide poses a severe health risk and must be addressed immediately.
