Yes, mold can grow in a wet dryer vent. Mold is a type of fungi, and fungi thrive in warm, moist conditions. Dryer vents need to be aired out so heat can escape and moisture can dry. If your dryer vents aren’t properly vented, the trapped heat and moisture will cause mold to grow, and the mold can spread to the dryer and even your clothes. Not only can this leave a musty smell on your freshly laundered clothes, but—more importantly—it also poses a health risk.

The length of an allowable dryer vent varies based on the local building codes and regulations. Typically, the maximum range is 25 to 35 feet. However, if the vent must have any 90-degree turns, you may see a reduction of five feet from the maximum. Some municipalities may have no specific maximum allowable length as part of the code. Typically, installers will run the vent over the shortest possible distance for safety. The dryer vent cleaning cost is less with a shorter vent length as well. 

You should have your dryer vent cleaned by a professional at least once per year. Over time, lint and other debris from your laundry get caught throughout the vent, causing a few different issues. A less severe problem caused by a clogged dryer vent is extended drying time for your clothes, which increases energy costs. More importantly, lint in a clogged dryer vent can easily catch fire, putting your household members and your home at significant risk. Keep in mind that decades-old dryer vent systems may need increased cleaning, so plan to complete this task twice per year.

Dryer vents need thorough cleanings one or two times a year, depending on family size and how often you run the machine. Failing to do so can put your home at an increased risk of fire. You should also schedule special cleanings if you notice that your dryer is taking longer to dry than normal, if you see lint building up on the outside flapper or in the vent itself, if you notice your dryer vent leaking water, or if your clothes have an odd odor on them after going through a drying cycle.
