For major blockages and root problems, we Hydro-Jet --- blow the pipes out using water under high pressure. Hydro-Jetting blows out roots, grease and anything else that might be blocking the drain. It's more effective than the usual cabling because it doesn't just unblock the drain, it cleans it. A clean drain will not snag foreign objects that could block the drain all over again. We believe that Hydro-Jetting is the future of drain and sewer clearing.
