Buyers typically pay for service line replacement to move or upgrade the main feed from the utility to the home. Costs hinge on amperage, distance, conduit type, permits, and labor. This guide presents clear cost ranges and drivers to help form a reliable estimate.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Project total | $2,000 | $6,000 | $14,000 | Includes materials, labor, and permits under typical conditions |
| Per‑foot trenching or trenchless install | $5 | $20 | $60 | Distance from utility meter to the weatherhead matters |
| Amperage upgrade (e.g., 100A to 200A) | $1,000 | $4,000 | $10,000 | Higher capacity often requires new panel, meter base, and disconnect |
| Permits and inspections | $100 | $800 | $2,000 | Local rules vary; includes inspection fees |
| Service drop or underground feed | $0 | $3,000 | $9,000 | Underground installs cost more due to trenching and conduit |
| Meter base replacement | $200 | $800 | $2,000 | Required with some upgrades or relocations |
| Disposal and cleanup | $50 | $300 | $800 | Minor but often included |

Overview Of Costs
Replacing a main service line typically runs from about $2,000 to $14,000 depending on amperage, distance, and installation method. The most common projects fall in the $4,000 to $8,000 range for a standard 100–200 amp upgrade with overhead service and new meter base. Factors such as whether the run is above ground or underground, the presence of a meter transfer, and local permit costs push the total toward the higher end.
Cost Breakdown
The following table outlines the primary cost components and typical ranges. It uses total project ranges and per‑unit estimates to help you model budgeting scenarios. Assumptions: single‑family home, standard 1–2 story, typical lot without major obstacles.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $1,000 | $3,000 | $8,000 | Includes conductors, meters, breakers, and connectors |
| Labor | $1,000 | $3,000 | $7,000 | Crew costs for permit‑acquired work |
| Equipment | $500 | $2,000 | $5,000 | New panel, disconnect, conduits, trenching equipment |
| Permits | $100 | $800 | $2,000 | Local jurisdiction fees and inspections |
| Delivery/Removal/Disposal | $50 | $300 | $800 | Waste handling and old gear removal |
| Warranty/Guarantees | $0 | $200 | $1,000 | Optional extended coverage |
What Drives Price
Key price drivers include amperage, distance to the utility, and whether the service is overhead or underground. Upgrading from 100A to 200A commonly adds $2,000–$6,000 in materials and labor. If the run is underground, expect trenching, conduit, and possibly restored landscaping, which can add $3,000–$6,000 or more to the project. A meter base relocation or replacement typically adds $500–$2,000 on top of the core work.
Cost By Region
Local market differences affect pricing. Three representative regions show typical deltas from the national average:
- Coastal metro areas: +10% to +25% versus national average due to higher labor and permit costs.
- Midwest and southern suburbs: near the national average, with occasional regional variances of ±10%.
- Rural or suburban areas: −5% to −15% versus national average due to lower overhead and crew costs.
Regionally driven factors include permit timing, utility coordination, and access to skilled electricians.
Labor & Installation Time
Project duration commonly spans 1 to 5 days depending on complexity, with longer times for underground runs or meter relocation. Typical labor costs align with local hourly rates and crew size. A standard residential service replacement often uses 2–3 electricians, plus a supervisor for coordination with the utility.
Real-World Pricing Examples
Three scenario cards illustrate common outcomes. These examples reflect typical market conditions and standard assumptions; real prices vary.
-
Basic scenario — 100A to 100A maintenance with minimal trenching and a simple overhead run.
- Specs: same amperage, overhead feed, no major relocation
- Labor: 8–12 hours
- Per‑unit: $6,000 total; $50–$150 per hour per worker
- Total: $2,500–$4,500
-
Mid‑Range scenario — 100A to 200A upgrade with meter base replacement and modest trenching.
- Specs: underground run to panel, new disconnect
- Labor: 16–24 hours
- Per‑unit: $5,500–$9,000
- Total: $5,000–$9,500
-
Premium scenario — 200A upgrade with underground feed across longer distance and full landscaping restoration.
- Specs: long underground conduit, new meter base, conduit and restoration
- Labor: 40–60 hours
- Per‑unit: $12,000–$18,000
- Total: $12,500–$22,000
Assumptions: region, specs, labor hours.
Potential Hidden or Additional Costs
Unexpected items can affect final pricing. Possible extras include utility coordination fees, temporary power outages during work, tree or landscape restoration, and expedited permit processing. Some jurisdictions require replacement of old wiring to meet updated code, adding material or inspection costs.
Ways To Save
Budget awareness and planning help reduce surprises. Consider obtaining multiple bids, coordinating timing with utility outages, and scheduling work during off‑season when rates may be lower. If possible, reuse existing trench paths or limit underground work to essential segments to minimize costs.
