This is a great company. Used them for dryer vent cleaning, power washing, and tile cleaning. This time it was for dryer vent cleaning and they got the job done efficiently. One thing to note, the service person will not go onto metal roofs that are wet as it is too hazardous. Ended up having reschedule last minute the appointment three times due to weather. The company was appreciative of looking after their workers safety and rescheduling was a breeze. The other thing to be sure to tell the company is if your dryer vent is vented through the roof so the worker can load the truck with a tall enough ladder for the job.
