Quoting prices over the phone without seeing a job is quite difficult.
However, if you can give me enough information, I can certainly give you a rough idea as to cost.
If you could please give me the following information when you call it will help me greatly:
1. Number of Stumps
2. Size of stumps (measured as diameter at ground level)
3. Access issues (ideally 36" width)
4. Any obstacles or hazards? (Steep slopes, steps, walls, paths, cables, pipes, drains,etc)
5. What you intend to do with the area after, as this will determine the depth of grind.
6. Waste disposal. Can the grindings stay on site?
