Most people are surprised HOW economical stump grinding is. There are several factors that determine the price: size of stump. Accessibility. And distance to the JOB site. Generally we charge by the inch based on the stump measurement illustrated below. Let's SAY YOU have TWO stumps. ONE is 32" across and the other is 17" across for a total of 49". We would typically charge $2.50 X 49" = $122.50 total cost. Cost PER inch varies by the size of the stump. Location and difficulty of the terrain. Note: ASK about pricing for volume discounts and Senior citizens. Prices quoted DO NOT include debris removal.
