The Duke’s Guarantee

Duke’s guarantees to kill all the roots in every sewer we treat and to eliminate main line stoppages caused by live tree roots. If live roots are found in a sewer within six months after the application, or if a treated sewer plugs up and floods due to tree roots during the guaranteed period, we will re-treat that section, at our own expense, or remit to the customer 100% of the payment we received to treat that section of sewer. Any section of sanitary sewer we treat will not plug up and flood due to tree root obstructions for a period of two years. The guarantee period begins on the date of treatment and ends two years after the date of treatment. When we perform a repeat application within six months of the expiration of the previous guarantee, the guarantee is extended for an additional three years.
