What Sets the Price of Fence Line Clearing in Michigan
The Gibson Environmental Services crew
More than 10 years clearing land, cutting trails, and running forestry equipment in Southeast Michigan.
Two fence lines of the same length are rarely the same job. One is light regrowth along a standing wire fence on dry ground beside a driveway; the other is a half mile of box elder trunks and grapevine over an old fence in a wet ditch, reached through a gate and across a lawn. The length matches and nothing else does, which is why fence line clearing is quoted after a look at the line rather than from a table.
This guide has no prices in it. It explains the nine things that set the price of fence line clearing in Southeast Michigan, how Gibson Environmental Services builds one flat project price from them, why the unit a quote is written in matters more than the number, and what to send so the quote is right the first time. For how a forestry mulching quote is built and what it includes, see how forestry mulching is priced; for the width question see the overgrown fence line guide.
Start With the Unit
A fence line is measured three ways, and a quote has to say which one it uses. Linear feet is the length of the line. Square feet is length times the width of the cleared strip. Acres is square feet divided by 43,560. Take one line, a quarter mile long and grown 20 feet wide: it is 1,320 linear feet, 26,400 square feet, and 0.61 acre, all at once. A figure per linear foot describes the length alone and says nothing about the width; a figure per square foot is the same job divided by a number twenty times larger; a figure per acre is divided by a number 43,560 times larger again. Put the same dollar amount after each unit and you have described three jobs that differ by orders of magnitude.
So the first thing to check on any fence line quote, ours or anyone's, is the unit. A quote that reads "per foot" should say whether that is a linear foot of fence or a square foot of ground, and what width it assumes. A quote per acre should say how the acres were measured. A flat project price should say what line, what width and what finish it covers. The length-to-acres table in the hub guide converts six lengths and six widths.
The Nine Factors
1. Length of the line
Paced, taped or read off a parcel map. Length is the easiest number to get and the one that scales everything else; a mile of light brush is still a mile of travel for the machine.
2. Width of the corridor
The width the brush has spread to, or the width you want opened, whichever the job calls for. Width multiplies length into area, and area is what the machine time follows.
3. Density and stem size
Grass and first-year saplings are a brush hog pass; a band of shrubs is a forestry mulching pass; trunks are slower again. Forest Service guidance notes that larger stems take disproportionately longer to grind and that the head and horsepower should match the tree size, which is why a row of six-inch box elder is a different job from a row of rose canes.
4. Terrain and wet ground
A ditch bank, a slope down to a creek or a wet corner changes how the machine works the line and when. Wet soil ruts under any machine, so wet stretches are scheduled for frozen ground or the dry end of summer, and that scheduling is part of the price.
5. Wire, posts, stones and pipes
What is inside the brush. Old wire, standing posts, a stone pile or a marked utility line slow the grinding, add hand work at the fence, and have to be flagged before the machine arrives.
6. Access
How the machine reaches each end of the line: a farm gate off the road, a side yard between two houses, a lane through the woods. Access that needs a lawn crossed or a gate widened is noted in the quote, and a photo of it settles the question.
7. Haul or leave
Forestry mulching leaves the brush as a chip strip where it stood, so there is nothing to pile, burn or haul; that is the default on a fence line. Asking for the chips raked thin or the old fence hauled away is extra work and is priced as such.
8. Travel
The drive from Royal Oak to the line, with the trailer. It is included in the flat price rather than billed separately, and it is one reason a job that straddles a county line is still one price.
9. Finish
A chip strip the mower can run is the standard finish. A strip raked thin for seeding, stumps ground below grade for a post auger, or the line walked and the fence inspected section by section are finishes you can ask for, and each is named in the quote.
How One Flat Project Price Is Built
The quote starts with the line: its length and width from your photos or a walk, which gives the square feet and acres. The density and stem size set the machine time per acre, and the terrain, the wet stretches and anything in the brush adjust it. Access and travel are added once for the job. The finish you asked for is named. The result is a single number for the whole line, written down before any machine moves, with travel and terrain already inside it, so there is no hourly meter running and no separate line for the drive.
What that means on the ground: the number does not change because the row turned out to be ten feet wider than the photo suggested, if the walk-through caught it; it does change if you add a second line or ask for the old fence to come out. Calls are answered 8 AM to 8 PM seven days a week, and form and text replies come back within one business day, so a line can usually be priced from photos inside a day or two.
What Published Studies Say Drives the Time
Fence line clearing is mastication in the research literature, and the published work agrees on what moves the time. A 2020 Forest Service bulletin on mastication reports that costs vary widely with equipment, terrain, site conditions and operator skill, that larger stems take disproportionately longer, that wet soils rut and compact under wheeled carriers while rubber tracks give the lowest ground pressure, and that the method pays off where there are many stems rather than a few. A 2010 Council on Forest Engineering study of a compact tracked carrier with a FECON drum head found the cost per acre most sensitive to the production rate, measured 0.32 acre per productive hour in dense shrub on slopes of 5 to 23 percent, and warned that light-shrub figures should not be extrapolated to heavier material. Those are the same factors as the list above, in a different vocabulary.
Why the Same Length Can Be a Different Job
| The line (all 1,000 feet long) | What is on it | Width and area | What the work looks like |
|---|---|---|---|
| Light regrowth along a standing wire fence, dry ground, gate at the road | Rose canes, first-year saplings, some honeysuckle | One pass each side, about 10 ft total: 10,000 sq ft, 0.23 acre | Mostly one forestry mulching pass per side with the brush hog on the open edges; the shortest version of the job. |
| Mixed autumn olive and box elder saplings both sides, one wet corner, access across a lawn | Shrubs to head height, saplings to a few inches, grape on the wire | Spread to about 20 ft: 20,000 sq ft, 0.46 acre | Full mulching of the band, hand work on the wire, the wet corner waits for frozen ground; the lawn crossing is planned on the walk-through. |
| Old farm row with trunks over a collapsed fence in a ditch | Box elder and cherry trunks, buried wire, stones, a ditch bank | Spread to about 35 ft: 35,000 sq ft, 0.80 acre | The slow version: trunks ground in pieces, wire found and flagged as it appears, bank worked from the top, finish by hand at the fence. |
Same length, three different jobs, and the differences are visible in a handful of photos. That is the whole argument for quoting a line after looking at it, and against any figure quoted sight unseen.
What to Send for a Quote
- The length of the line, paced or from a map, and whether it is one side of a fence or both.
- How wide the brush has spread, measured from mowed grass to mowed grass, or the width you want opened.
- Three photos along the line: each end and the middle, taken from the open side.
- One photo of the gate, lane or side yard the machine would use.
- What is in the brush: old wire, posts, stones, a utility mark, trees you want kept.
- The finish you want: chip strip, raked for seed, line walked for a fence inspection.
- Any schedule constraint: turnout, hay, a fence crew's date, a wet stretch that needs frozen ground.
With those seven things, Gibson Environmental Services sends back one flat project price for the whole line, travel included.

Common Questions
How is fence line clearing priced?
As one flat project price for the whole line, built from the length and width of the strip, the density and stem size of what is on it, the terrain, anything in the brush, the access and the travel, with the finish named. It is written down before any machine moves.
Is fence line clearing priced per foot?
Gibson Environmental Services quotes a flat price for the line rather than a rate per foot. Where you do see a per-foot figure, check whether it means a linear foot of fence or a square foot of ground, and what width it assumes; the two differ by the width of the strip.
Why does the width matter if the fence is a line?
Because the machine clears an area, not a line. A quarter mile of fence cleared 10 feet wide is 0.30 acre; the same quarter mile cleared 33 feet wide is a full acre, more than three times the ground.
What makes one fence line slower than another of the same length?
Stem size first, then density, then what is in the brush and under it: trunks, old wire, stones, a ditch bank, a wet corner. Published mastication studies list the same drivers: stem size, terrain, soil moisture and operator skill.
Is travel charged separately?
No. The drive from Royal Oak is inside the flat project price, and so is the terrain. A line that crosses a township or county line is still one price.
Does leaving the chips cost less than hauling brush away?
Leaving the chips is the standard finish for forestry mulching, since the brush is ground where it stood and there is nothing to haul. Raking the strip thin for seed or hauling an old fence away is extra work and is named in the quote.
Can I get a price from photos?
Usually. Three photos along the line, one of the access, the length and the width are enough for most lines; a long farm row or a line with a lot of old wire gets a walk-through first. Replies to the form or a text come back within one business day.
Where can I read how forestry mulching is priced?
In how forestry mulching is priced on this site, which explains what drives a forestry mulching quote and what one flat project price includes. This guide deliberately keeps to the factors and the units.
