Stump grinding vs. stump removal

A stump grinder is a machine with a spinning cutting wheel. The operator sweeps it across the stump and takes it down to chips, usually to a set depth below the surface. The roots that spread out from the stump are left in the ground to decay over time, apart from any surface roots the operator also grinds.

Full removal digs around the stump and pulls it out with its main roots, using a machine or hand tools. The wood and soil that come up have to be hauled away or spread, and the hole has to be filled and compacted. It is more disruptive to the yard, and it needs more careful checking for buried lines.

Grinding fits most residential jobs. It leaves the ground largely undisturbed, a grinder can reach stumps in yards where a digging machine cannot, and it is the quicker way to get a stump out of the way of a mower or a patio plan. If the aim is turf, mulch or a garden bed over the spot, grinding is usually enough.

It is also easier to price in a calculator. Cost follows stump diameter, and the main variables are depth, access and the extras you want. Those are the inputs the EstiCube stump grinding calculator uses.

Removal is worth asking about when the roots, not just the stump, are the problem. A spot that will carry a structure, a hard surface or a new tree planted in the exact same place may call for more of the old root mass to come out. A tree care professional can tell you whether the roots left after grinding would get in the way.

Removal also means a larger quote and more work to restore the ground afterward, so it is worth getting a quote for both methods where either could work. The calculator does not price excavation, so compare any removal quote against the grinding figures in this guide on the same job.

The default calculator job is three 18-inch stumps at standard depth, about 8 inches below grade, with open access. Grinding is $153 and the $75 trip charge brings the total to $228. The options below change that job one at a time, so you can see how much each decision is worth.

Pricing for the three extras is per stump: $45 for surface roots, $30 for chip removal and $35 for backfill with topsoil and seed. Deep grinding, about 12 inches and described in the calculator as the option for replanting, multiplies the grinding line by 1.3. Switching on all three extras on the default job takes it to $558.

Grinding leaves a mound of loose chips, and the calculator estimates about 0.3 cubic yards of them for the default job. They can be hauled off, kept for mulch, or used to fill the hole, but the pile is bulky compared with the stump. Ask in advance what your contractor does with them.

A ground stump leaves a depression once the chips settle or are removed, so backfill and seed is worth pricing. On a single 18-inch stump with all three extras the calculator total is $248, against $138 for grinding alone, so the cleanup can cost more than the grinding itself.

The 811 site says to contact 811 before any digging, regardless of depth, because some buried utility lines are only inches below the surface. Both grinding and removal go below grade, and removal disturbs more ground, so request line locating a few business days ahead and tell the contractor where marks and any private lines such as irrigation or landscape lighting run.

For the choice itself, the International Society of Arboriculture's Trees Are Good site explains what arborists do and links to a way to find one. Compare at least two quotes, ask each contractor for the same scope, and make sure the quote names the method, the depth and what is left on site.
