Best Flooding Prevention in Washington DC

Roto-Rooter arrived at my home within 2 hours of my call for service to clean out my clogged sewer line. John (the plumber) completed his work, including clean-up within one hour. After John left you would not have know that Roto-Rooter had been on site. This is the best service that I have received from a plumber during my 8 years in DC.
