Main Shutoff Valve Replacement Cost Breakdown Guide
The breakdown layer prints apart by frame: the valve, labor, and permit lines and the access and trenching lines on Frame A and Frame B, each inside its own frame.

The breakdown layer, priced apart
| Frame | Component line, as published | 2026 band |
|---|---|---|
| Frame A | labor, per hour | $45-$200 |
| Frame A | permits | $150-$500 |
| Frame B | labor, scheduled, per hour | $75-$150 |
| Frame B | permit fees | $30-$500 |
Every figure here is a published line inside its own frame, never added into a new total. Access is the pacing line in both frames: Frame A prints a full location table, and Frame B prints trenching as its own line. The project whole prices on the main shutoff valve hub; the type layer on the by-type guide.
Valve and labor lines, as reported
| Line, as published | Frame | 2026 band |
|---|---|---|
| Most valve types, valve alone | Frame A | $10-$50 |
| Most valves, on average, valve alone | Frame B | $10-$50 |
| Heavy-duty models, valve alone | Frame B | $150 or more |
| Labor | Frame A | $45-$200 per hour |
The valve itself is the smallest priced line in both frames -- the same $10 to $50 average band on each -- and the hourly labor line carries the project above it. The two hourly readings are reported apart and never averaged.
Access and trenching lines, as reported
| Line, as published | Frame | 2026 band |
|---|---|---|
| Basement access | Frame A | $180-$220 |
| Buried, deep | Frame A | $240-$1,000 |
| Average when trenching is required | Frame A | $875 |
| Trenching | Frame B | $5-$12 per linear foot |
Frame A crosses the project with location: basement access at the low end, then in-ground, vault, and buried readings above it, with the project average rising to $875 once a trench is required. Frame B prints trenching per linear foot as its access reading.
Permit and remaining lines, as reported
| Line, as published | Frame | 2026 band |
|---|---|---|
| Permits, headline reading | Frame A | $150-$500 |
| Permit fees, municipal | Frame B | $30-$500 |
| Surface repairs | both frames | no priced line printed |
| Vault or box location | Frame A | $200-$750 |
The permit line prints in both frames at different widths -- a counting difference, read as published and never merged. Neither frame prints a surface-repair line for this project; that absence is recorded here rather than filled from another project's table.
Replacement and first-installation readings, as reported
| Reading, as published | Frame | 2026 band |
|---|---|---|
| Replacement, most homeowners | Frame A | $375-$600 |
| Replacement, average | Frame A | $500 |
| Replacement, materials and labor counted in | Frame B | $250-$600 |
| First installation, no house-side shutoff, split out | both frames | no priced line printed |
Both frames publish this project as a replacement reading, with access named as the line that moves it. A first installation on a main with no house-side shutoff prints in neither frame as a band of its own; it is read against the replacement tables on the companion guides.
Reading a breakdown quote, by frame
A component line answers the line-item question: the valve, the hourly labor, the permit, or the access and trenching reading. A quote naming one component is read against its own table, and no other frame's total.
- Valve lines read apart from labor lines and installed totals
- Permit and trenching lines read beside the typical band of the same frame
- Each frame's breakdown reading read on its own frame only
Frequently asked questions
What does the valve alone print at, as published?
Most valve types at $10 to $50 on Frame A, printed as valve-alone lines -- gate at $10 to $50, ball at $10 to $20. Frame B prints most valves at $10 to $50 on average, with heavy-duty models at $150 or more. Neither reading is an installed total.
What labor lines do the frames print, as published?
Frame A prints plumber labor at $45 to $200 per hour. Frame B prints scheduled labor at $75 to $150 per hour, inside Frame A's wider band. The two readings are reported apart and never averaged.
What do permits print at, as reported?
Permits at $150 to $500 on Frame A's headline reading, and municipal permit fees at $30 to $500 on Frame B. The widths differ by counting source; each permit line is read on its own frame, beside that frame's project band, and never merged.
What do the access and trenching lines print at, as reported?
Frame A prints location lines from basement access at $180 to $220 up to buried, deep at $240 to $1,000, with the average rising to $875 when trenching is required. Frame B prints trenching at $5 to $12 per linear foot.
Do the component bands add up to a new total on this guide?
No. Components are printed as separate readings beside the totals their own frame publishes. This guide never sums component bands into a new total, and never carries a component from one frame against a total from the other.
