A previous contractor did not clean or secure the dryer vent hose properly to the vent outlet. While doing laundry the vent hose detached and fell behind the dryer (in a confined space with a washer/dryer stacked unit).
The Dryer Vent Experts showed up for the appointment on time, inspected the hose for damage, cleaned the vent outlet surface, installed a screw to keep the hose in place, and used the correct type of tape (duct doesn't work) to seal the connection. All within 15 minutes of arriving. They tested the dryer, tidied up the work space and handled payment on site. They also inspected the vent itself in case it needed to be cleaned.
I am so impressed by the friendliness, professionalism and knowledge these technicians have. Hire them.
