Labor lines, priced apart in Frame B
| Frame | Labor line | 2026 band |
|---|---|---|
| Frame B (labor only) | in-ground installation, full excavation | $1,500-$3,500+ |
| Frame B (labor only) | professional labor, by tier | $800-$3,500 |

Every figure here is a Frame B labor line, never folded into a Frame A total. The excavation line is the largest labor line in either frame, and posted marketplace assembly jobs run in the low-to-mid hundreds, as published. The project whole prices on the in-ground trampoline installation hub; the form comparison on the in-ground vs. above-ground guide.
Excavation and equipment-rental lines, as reported frame lines only
The excavation layer prints as cost lines only, in both frames, kept apart: Frame A prints an excavation equipment rental line at $250 to $400 on its mid-market tier, the entry tier printing $0 on that line and the premium tier folding rental into contractor labor. Frame B prints dirt removal alone at about $500 as a single published line.
Drainage and dirt-disposal lines, as published
| Site-prep line | Frame | Published band |
|---|---|---|
| Subsurface drainage, basic class | Frame A | $50 |
| Subsurface drainage, mid class | Frame A | $150-$300 |
| Subsurface drainage, premium class | Frame A | $400-$800 |
| Dirt disposal and haul-away, mid tier | Frame A | $150-$300 |
| Dirt disposal and haul-away, premium tier | Frame A | $400-$700 |
| Retaining wall panels, by tier | Frame A | $150 / $400 / $700 |
The drainage line is Frame A's widest site-prep band, from a $50 basic class to $400 to $800 premium. The disposal line prints at $150 to $300 mid tier and $400 to $700 premium tier, and the retaining wall panels line at $150, $400, and $700 by tier, each named apart.
Slope, grading, and seasonal lines, as published
The adder layer prints as factor lines in Frame B: a slope of more than 3 degrees prints extra grading charges; metro labor rates print 20 to 30 percent above rural rates; and off-season pricing prints 10 to 15 percent below peak-season lines.
The playground neighbour prices a different labor scope, differentiated head-on
The backyard playground page prices play structure assembly as its own project; this guide prices one trampoline project's excavation, drainage, and disposal lines. No trampoline labor line appears on the playground page, and no playground line appears here.
