Surface Root Grinding in the Niagara Region
Ridges of root snaking across the lawn, heaving the patio stones or poking through a new garden bed can be ground down flat. Here's how, and when it's a bad idea.
Roots That Trip, Lift or Get in the Way
Some trees grow roots right along the top of the soil, especially maples, willows and poplars, and especially in the heavy, wet ground common across much of Niagara. Over the years those roots thicken into hard ridges. The mower blade hits them, kids trip on them, and paving stones and walkways start to tilt as roots push up underneath.
Roots also tend to get worse after a tree is cut, not better. The stump stops feeding them, they slowly rot, and the soil around them settles, leaving the root standing even higher above a sinking lawn.
A grinder can take those ridges down below the surface in a fraction of the time it would take to chop them out with an axe, and with far less damage to the lawn around them. The trench it leaves gets filled and seeded, and the yard is flat again.
Root Grinding Helps If…
- A tree has already been removed and its old roots are still breaking the surface.
- Roots are lifting a walkway, patio stones or an edge of the driveway.
- You keep hitting roots with the mower or tripping on them.
- You're putting in a new bed or path and roots are in the way.
- A stump has already been ground but the roots running off it still show.
Living Trees Need a Different Conversation
Roots of a removed tree: the easy case
If the tree is gone, its roots are fair game. We grind them out as far as you need, fill the trench and leave the area level. This is often done on the same visit as the stump.
Roots of a living tree: ask first
Grinding roots off a tree that's still standing can harm it. Surface roots carry water and anchor the tree; cutting big ones, especially close to the trunk, can starve part of the canopy or make the tree less stable in wind. We're stump and root grinders, not arborists. If the roots belong to a tree you want to keep, we'll suggest you get an arborist's opinion first on which roots can be cut safely. Once you know that, we can grind exactly those and leave the rest.
Where surface roots cause trouble
- Mowing strips and lawn edges where blades and trimmer lines take a beating.
- Walkways and patio stones that rock or lip up at the edges.
- Garden beds where nothing gets established because the soil is full of root.
- Play areas and side yards where people walk without looking down.
Which trees cause the most trouble
In Niagara yards, silver maples, Norway maples, willows and poplars are the usual suspects. They grow fast, like moisture and spread their roots wide and shallow, especially in clay that stays wet below the surface. Spruce can do it too on thin soil. Oaks and most fruit trees are better behaved, rooting deeper. If you're planting a replacement, choosing a deeper-rooted species and keeping it away from paths saves this job in twenty years.
Close to slabs and paths
Roots under the edge of a walkway can be ground back from the side, though lifted stones may still need resetting afterwards. That part is a job for whoever laid the path; we'll leave the ground ready for them.
How Root Grinding Goes

Rough length of root and what it runs under or near.
Locates done
Buried lines marked, since roots and pipes often share space.
Grind the ridges
Roots taken down below the grass and trimmed back clean.
Fill and seed
Trench filled with grindings and soil, ready for grass.
What Root Grinding Costs
Roots are priced by length and thickness rather than by stump width, and they're usually cheaper when done on the same trip as a stump. Give us a rough measurement of how far the roots run and how thick they are where they show. See the prices page for how a full yard job adds up.

Count them
Every stump you want gone, small ones included. A cluster of little ones adds up.
Measure across at the ground
The widest point, right at soil level, in inches. That number drives the price more than anything.
Tell us about getting there
Gate width, steps, slopes, fences, beds or pools near the stump.

Root Grinding Questions
Will grinding roots kill my tree?
It can, depending on the tree, how big the roots are and how close to the trunk. For a living tree you want to keep, get an arborist to say which roots can safely go before anyone cuts them.
Can you grind roots under a walkway?
We can grind back the parts we can reach from the side. Stones that have already lifted will need resetting by a hardscaper once the roots are cut.
Do you fill the trench afterwards?
Yes. The grindings and soil go back in and get levelled so you can seed it.
