Why Do I Have A Bird Nest In My Dryer Vent?

Bird nest in a dryer vent is not very common, but we do get calls to clear them out every now and then. However, there are always questions we get from the customers about the reason the bird nest is there to begin with.
Why Do I Have A Bird Nest In My Dryer Vent?
Obviously we can say the most significant reasons is the lack of protection to your dryer vent exit. Every dryer vent should have a flap cover that rises when air pushes through, while shutting off while the machine is done and there is not more air flow. Over the years many of the outside fittings either lose their flap by breaking. In addition, is many cases a build up of lint on the dryer vent fitting could also block the flap from moving. Therefore, allowing free entrance to the dryer vent.
Moreover, if you have not done your yearly maintenance and cleaning to your dryer vent, the velocity of the air flow drops. This will make it much easier for the a bird or a rodent to nest inside your dryer vent.
Therefore, of course we strongly recommend to clean your dryer vent at least once a year in order to avoid issues like that.
Bird Nest In Your Dryer Vent Is A Major Fire Hazard.
Bird nests are quickly built. We had an experience with a dryer vent that had no flap and had a bird nest at the exit of it. After cleaning it the customer said he will replace the outside fitting by himself, which he failed to do right away. We came back a week later to a fully build bird nest all over again.
Once the bird nest is complete, it acts as a lint catcher. It will block and catch the lint flying out through the vent and impose a major clog the is hard to remove. We removed an 8 foot long bird best and lint sleeve from a dryer vent before.
As having your dryer vent blocked for air flow, a fire hazard is a real risk, please make sure to check your air flow and call Dr. Dryer Vent Cleaning & Air Duct Cleaning OC for help with dryer vent cleaning.
