This is a complete job video of an external dryer vent I cleaned at an apartment complex. This unit had 100% blockage due to an error in installing a dryer vent cap. Dryer vent cleaning business is relatively easy to start doing but comes with a lot of variety of problems you need to learn to deal with. I would suggest having a seasoned veteran on speed dial for when you run into problems that are uncommon. But this was fairly simple, straight forward type of job. Enjoy! #dryerventcleaning
