Dryer Vent Cover Replacement Under 30 Minutes!

According to the National Fire Protection Association, dryers and washing machines cause approximately 15,970 fires every year, and dryers cause 92% of them.

Faulty parts and lack of maintenance are the main reasons behind these incidents. That is why you must take care of your home appliances.

One of the most important parts of dryers is a vent cover. It allows the dryer air and lint to escape while blocking outside air and other residues. If it can’t function properly, your dryer vent will get filled with dryer lint, which is the main reason behind causing these fires.
