Main water line repair costs a published average of $1,025, with a $354 – $1,696 range – figures HomeAdvisor publishes.2 Angi, its corporate sibling, presents two different general figure sets for the same scope on its page; the discrepancy is unresolved, so Angi’s general average and range are omitted here, while its clearly scoped tables are kept.1 Fixr (updated January 2025) publishes separately, and the pages state no shared sourcing; it scopes its $1,000 average to repairing an easily accessible damaged pipe, with a $500 – $2,000 range and a $4,000 high end (replacing a large, difficult-to-access pipe section).3 Where the publishers’ figures differ, they are presented separately below. Prices are national averages*.
*National averages, not local quotes. Your price depends on the problem type, pipe material, accessibility, and whether excavation is needed.

What the sources say
| Source | Headline figures | Notes |
|---|---|---|
| Angi (2026 data, updated Sep 2026) | General average/range omitted (page presents two different figure sets for the same scope); scoped tables kept: $100 – $200 per linear ft underground, repair-type and size tables | Corporate sibling of HomeAdvisor |
| HomeAdvisor (2025 data, updated Jun 2026) | $1,025 average; $354 – $1,696 range; corroded line repair $600 – $5,000 | Internally consistent on its general figures |
| Fixr (updated Jan 2025) | $1,000 average scoped to an accessible pipe; $500 – $2,000 range; high end $4,000 | Separately published, pages state no shared sourcing |
Cost by repair type
Angi and HomeAdvisor publish overlapping repair-type pricing (matching sibling figures where shown); Fixr publishes its own tables for repairs and for part replacements (labor included):1,2,3
| Repair type | Angi | HomeAdvisor | Fixr |
|---|---|---|---|
| Valve repair (leaky valve) | $150 – $700 | $150 – $700 | — |
| Valve replacement | $150 – $300 | $150 – $300 | $250 – $1,000 |
| Cracked pipe | $500 – $1,000 | — | — |
| Broken pipe or section | $500 – $5,000 | — | $400 – $2,000 |
| Corroded pipe | $600 – $5,000 | $600 – $5,000 | — |
| Leak (general) | — | — | $300 – $3,000 |
| Copper pipe soldering | — | — | $500 – $2,000 |
| Line section replacement | — | $100 – $200 per linear ft | $500 – $4,000 |
The publishers’ figures differ on most rows and are kept separate. HomeAdvisor also publishes averages within its ranges: $425 for valve repair and $2,800 for corroded line work. Fixr’s page presents two different figures for leaking shut-off valve repair; the discrepancy is unresolved, so Fixr’s valve-repair figure is omitted, while its separately scoped valve-replacement figure is unaffected.1,2,3
Cost by replacement part
Fixr prices specific part replacements (labor included):3
| Part | Replacement cost (Fixr) |
|---|---|
| Shut-off valve handle | $150 – $750 |
| Tap (connection to city line) | $200 – $400 |
| Water pressure regulator | $250 – $1,000 |
| Pipe section | $500 – $4,000 |
Fixr also prices repairs by symptom: vibrating water line at $250 – $4,000, low water pressure at $250 – $4,000, discolored water at $300 – $4,000, and calcium buildup at $500 – $4,000.3
Cost by pipe length and location
Angi prices repairs by damaged-section length, with sharply different rates aboveground ($1.50 – $12 per linear ft) versus underground ($100 – $200 per linear ft):1
| Damaged section | Aboveground (Angi) | Underground (Angi) |
|---|---|---|
| 10 linear ft | $15 – $120 | $1,000 – $2,000 |
| 20 linear ft | $30 – $250 | $2,000 – $4,000 |
| 30 linear ft | $45 – $350 | $3,000 – $6,000 |
| 40 linear ft | $60 – $475 | $4,000 – $8,000 |
| 50 linear ft | $75 – $600 | $5,000 – $10,000 |
| 60 linear ft | $90 – $725 | $6,000 – $12,000 |
HomeAdvisor publishes the same $100 – $200 per-linear-ft figure for excavating and replacing broken underground sections (matching sibling figure).2
Cost by pipe material
Both siblings price pipe materials per linear foot, but their copper figures differ with no stated reason, so the columns are kept separate:1,2
| Pipe material | Angi (per linear ft) | HomeAdvisor (per linear ft) |
|---|---|---|
| Copper | $2 – $10 | $2 – $8 |
| CPVC | $0.50 – $1 | $0.50 – $1 |
| PEX | $0.40 – $2 | $0.40 – $2 |
| Polyethylene | — | $2 – $5 |
| Fiberglass | — | $6 – $10 |
| Iron | — | $6 – $10 |
Angi prices repair materials overall at $0.40 – $8 per linear ft.1
Labor costs
Angi reports plumber labor at $70 – $120 per hour; HomeAdvisor and Fixr each report $45 – $200 per hour (separately published figures, and the pages state no shared sourcing).1,2,3 HomeAdvisor and Fixr both describe a moderate crack repair taking about a day and costing around $800.2,3 For excavation work, Angi reports an excavator operator at $120 – $150 per hour and trenching at $400 – $1,200.1
Repair vs. replacement
HomeAdvisor reports full water line replacement averages about $2,000, or $50 – $250 per linear ft, and that older lead or galvanized lines must be replaced rather than repaired, at $350 – $2,000 for new lines.2 Fixr prices trenchless replacement at $75 – $150 per linear ft.3
Accessibility
HomeAdvisor reports simple, easy-to-access repairs run $150 – $700, while difficult-to-access areas or large section replacements can reach $3,000; repairs under a concrete slab cost more because of the labor involved.2
Restoration and related costs
Angi and HomeAdvisor both report landscaping restoration at $1,200 – $6,300 after excavation (matching sibling figures).1,2 Angi also reports floor replacement at $1,500 – $4,900 when the line runs beneath flooring, drywall removal at $0.50 – $1 per sq.ft. (plaster $1.50 – $3), and new drywall at $400 – $650 per 100 sq.ft.1 HomeAdvisor reports a professional water main inspection costs $165.2
Permit requirements and fees vary by municipality; both publishers note permits may be required, particularly for trenched work, without a consistent published range.1,2
