I was very concerned about the safety of the dryer venting system on both of my dryers. When I looked online I realized that the currently venting system was a fire hazard. I found Dryer Vent Doctor online and watched their videos and right away I knew this was exactly who I needed to help me. I called, they came the next day, and everything was fixed up quickly. I also decided to sign up for their annual vent cleaning service. All in all, a fantastic experience.
