Stump grinding rates vary with the diameter of the tree trunk. A 6” diameter stump is typically $10, a 1 foot diameter stump is usually around $40-50, a 2 foot diameter stump is usually in the $100 range. For lager stumps there are more factors that get considered like how close to the ground is it cut, and how many surface roots there are, and how deep does it need to be ground. Grinding depth on larger stumps is a major cost factor. If it is a type of tree that grows back, like redwood, oak, liquid amber, etc, it will need to be ground to about 1-1/2 feet deep in order to kill it so it won’t grow back. If it is a type tree that doesn’t grow back, like pine, fir, maple etc, it can be ground just 6 inches deep and then covered up with dirt as a cheap alternative. A large stump ground at 6 inches deep is considerably less money than a large stump ground to 1-1/2 feet deep. Small stumps are always ground to full depth (1-1/2 ft.) We have a $100-$120 minimum depending upon location.
Stump grinding can create lots of wood chip. The wood chip can be used as mulch on-site or added to your green waste can. The wood chip can also be left in the hole where the stump used to be.
