Author: CostGuideHQ Editorial·✓ Fact-checked·Updated July 2026·8 min read·6 sources·US national averages, USD
Quick answerQuick answer: Fixing a leaking pipe typically costs $250 to $850 for a straightforward repair, averaging around $500 nationally. Slab leaks and leaks hidden behind a wall cost far more — up to $4,700 — once you add leak detection, drywall access, and possible emergency call-out fees (Angi, HomeAdvisor).
  • A typical pipe leak repair costs $250 to $850, averaging about $500 nationally (Angi, HomeAdvisor).
  • Leak location drives the price more than anything else: an accessible pipe runs $100 to $500, but a leak behind a wall or ceiling climbs to $500 to $5,000 or more (HomeGuide).
  • Slab leaks are the costliest common type, averaging $2,280 with a typical range of $630 to $4,400, plus $150 to $400 for detection (HomeAdvisor).
  • Emergency or after-hours repairs cost 1.5 to 3 times more than standard rates (Angi), and Fixr cites a flat $200 to $300 emergency call-out fee on top of a higher hourly rate.

What affects the cost?

  • Leak location and accessibility — an exposed pipe under a sink or in a basement runs $100 to $500, while a leak behind a wall or ceiling that requires opening drywall climbs to $500 to $5,000+ (HomeGuide); Angi's own location breakdown shows the same pattern: an exposed pipe in a crawl space is about $150, a pipe behind a kitchen cabinet is about $500, and a pipe in a ceiling runs $700 to $2,500 for the pipe repair alone
  • Slab leaks — the costliest common leak type, since it's hidden under the foundation and needs detection plus tunneling, concrete breaking, or rerouting: HomeAdvisor puts the national average at $2,280, typical range $630 to $4,400, with a low end of $300 and a high end of $6,750
  • Leak detection — Angi's diagnostic fee runs $80 to $100; HomeGuide's minimum call-out/diagnostic fee is $50 to $200, plus $125 to $500 for a camera inspection if the source isn't obvious; HomeAdvisor prices slab leak detection specifically at $150 to $400, averaging $280
  • Emergency or after-hours service — Fixr cites a $150 emergency hourly rate plus a $50 to $200 transportation fee and a $200 to $300 flat emergency call-out fee; Angi notes emergency plumbers typically cost 1.5 to 3 times more than standard rates; HomeGuide puts emergency plumber calls at $100 to $350+ per hour
  • Drywall and ceiling restoration after wall access — Angi prices drywall repair at $50 to $75 per square foot (a typical job runs $250 to $750, a full ceiling $320 to $1,300); HomeGuide's figures are similar at $50 to $100 per square foot for both drywall and ceiling repair
  • Pipe material — Angi's per-linear-foot repair/replacement costs run PEX $0.40 to $2, PVC $0.50 to $5, CPVC $2 to $8, galvanized steel $3 to $8, copper $2 to $10, and cast iron $10 to $20
  • Labor rates — plumbers charge $45 to $200 per hour across sources (Angi, HomeGuide, Fixr), with Fixr noting most plumbers charge around $90 an hour, plus a typical minimum service fee of $50 to $100

How much does it cost to repair a leaking pipe?

Most homeowners pay $250 to $850 for a straightforward pipe leak repair, averaging around $500 nationally (Angi) — and HomeAdvisor’s own data lists an identical $250-$850 range, since the two sites share underlying cost data. Angi’s full spread runs wider, from $150 for the simplest fix up to $4,700 for the most complicated jobs, which is why “how much” depends heavily on where the leak is and how hard it is to reach. Thumbtack’s real transaction data lands close by — a national average of $228 to $752, with most people paying around $415 — while Fixr reports a lower, narrower average of $150 to $350. Those tighter figures describe a typical, accessible, non-emergency repair; once a leak is hidden behind a wall or under a slab foundation, cost climbs well beyond these averages, sometimes requiring drywall repair or even water damage restoration on top of the plumbing work itself.

How much more does a slab leak cost to fix?

A slab leak — a pipe leaking under your home’s concrete foundation — averages $2,280, with a typical range of $630 to $4,400 (low end $300, high end $6,750), according to HomeAdvisor. Because the pipe is hidden under concrete, detection comes first: plan on $150 to $400, averaging $280, just to pinpoint the leak with acoustic or electronic tools. From there, a plumber chooses a repair method based on the leak’s location and your slab’s condition — options include a cured-in-place lining ($80 to $250 per linear foot), rerouting the line elsewhere ($600 to $4,000), or breaking into the slab itself. Labor alone runs $500 to $4,000, or $75 to $150 per hour, since slab leak repair is slow, careful work. If the foundation has settled or needs stabilizing afterward, foundation crack repair and underpinning add further cost — HomeAdvisor prices underpinning at $2,500 per pier or $5,000 to $10,000 total.

What affects the cost?

  • Leak location and accessibility. An exposed pipe under a sink or in a basement costs $100 to $500 to fix; a leak behind a wall or ceiling, which requires opening drywall, runs $500 to $5,000 or more (HomeGuide).
  • Slab leaks. The costliest common leak type — HomeAdvisor’s national average is $2,280, range $630 to $4,400, because of the detection work and access method involved.
  • Leak detection. A basic diagnostic visit costs $80 to $100 (Angi); a camera inspection for a hidden source adds $125 to $500 (HomeGuide).
  • Emergency or after-hours service. Emergency plumbers typically cost 1.5 to 3 times more than standard rates (Angi); Fixr cites a $150 emergency hourly rate plus a $200 to $300 flat call-out fee.
  • Drywall and ceiling restoration. Patching walls opened up to reach the pipe costs $50 to $75 per square foot (Angi), or $50 to $100 per square foot per HomeGuide’s figures.
  • Pipe material. Repair or replacement per linear foot ranges from $0.40 to $2 for PEX up to $10 to $20 for cast iron (Angi). “Copper has gone up in price. So people are starting to look at alternatives,” says Richard Trethewey, plumbing expert at This Old House.
  • Labor rates. Plumbers charge $45 to $200 per hour across sources, plus a typical $50 to $100 minimum service fee — one San Diego plumber quoted to Thumbtack starts around $55 an hour.

How to lower your pipe leak repair cost

  • Call at the first sign of a leak rather than waiting — a small accessible leak costs $100 to $500 to fix (HomeGuide), while a leak left to spread behind a wall or under a slab can run into the thousands.
  • Avoid emergency call-outs when it’s safe to wait. Shutting off your main water valve and scheduling a standard visit instead of an after-hours emergency call can save 1.5 to 3 times the repair cost (Angi).
  • Get a firm estimate before drywall work starts, since patching walls or ceilings after pipe access adds $50 to $100 per square foot on top of the repair itself (HomeGuide).
  • Ask whether a repipe makes more sense if leaks keep recurring in old galvanized or cast iron pipes — a full whole-house repipe or targeted water line replacement can be cheaper than repeated point repairs over time.
  • Get multiple quotes, since hourly labor rates alone range from $45 to $200 across sources (Angi, HomeGuide, Fixr). Maria Neumann, owner of Water Damage Recovery in Northern California, warns that cutting corners on contaminated water damage almost always costs more to fix later on (Thumbtack) — a caution that applies just as much to picking a plumber for the underlying leak.

Prices vary by region, leak location, and pipe material, so treat the figures above as a planning budget. Get two or three local quotes, and confirm whether leak detection, drywall repair, and emergency fees are included, before committing to a final number.

Frequently asked questions

How much does it cost to fix a leaking pipe?
Most straightforward pipe leak repairs cost $250 to $850, averaging around $500 nationally (Angi). Angi's overall range stretches from $150 for the simplest fix up to $4,700 for the most complex jobs, and HomeAdvisor's own data lists an identical $250-$850 typical figure.
How much does it cost to fix a slab leak specifically?
A slab leak averages $2,280, with a typical range of $630 to $4,400 (low end $300, high end $6,750), according to HomeAdvisor. Detection alone runs $150 to $400, averaging $280, before any repair work begins.
Why does a leak behind a wall cost more than one under the sink?
Accessible leaks under a sink or in a basement cost $100 to $500 to fix, but a leak behind a wall or ceiling requires cutting into drywall to reach it, pushing the cost to $500 to $5,000 or more (HomeGuide). Angi's figures show the same jump — about $150 for an exposed pipe versus $700 to $2,500 for a pipe in a ceiling.
How much does leak detection cost?
Plan on $80 to $100 for a basic diagnostic visit (Angi) or $50 to $200 for a minimum call-out fee (HomeGuide). If the source isn't obvious, a camera inspection adds $125 to $500 (HomeGuide), and slab leak detection specifically runs $150 to $400, averaging $280 (HomeAdvisor).
How much more do emergency or after-hours repairs cost?
Emergency plumbers typically charge 1.5 to 3 times more than standard rates (Angi). Fixr cites a $150 emergency hourly rate plus a $50 to $200 transportation fee and a $200 to $300 flat call-out fee, while HomeGuide puts emergency plumber calls at $100 to $350 or more per hour.
Does the price include drywall repair after the plumber accesses the pipe?
No, it's a separate line item. Angi prices drywall repair at $50 to $75 per square foot (a typical job runs $250 to $750), and HomeGuide cites a similar $50 to $100 per square foot for both drywall and ceiling repair.
Why do pipe leak repair cost estimates vary so much between sources?
Angi's $150-$4,700 range and HomeAdvisor's matching $250-$850 typical figure (the two sites share underlying data) capture the widest spread because they include slab leaks and complex access. Fixr's $150-$350 average and Thumbtack's real-transaction $228-$752 range (typical spend $415) both describe a standard, non-slab, non-emergency repair, which is why they run narrower.

Angi's dedicated pipe-leak-repair page reports the most complete headline figures for a single leak repair — normal range $250 to $850, national average $500, low end $150, high end $4,700 — and anchors national_average_usd, range_low_usd, and range_high_usd here. HomeAdvisor's slab-leak page independently lists an identical 'Pipe leak repair: $250-$850' line in its own cost-by-repair-type table, confirming Angi and HomeAdvisor (both owned by Angi Inc.) share underlying data for the generic case; HomeAdvisor's slab-leak-specific figures (average $2,280, range $630-$4,400, high end $6,750) sit inside Angi's overall $4,700 ceiling and explain why the full range needs to stretch that far. Fixr's headline is narrower and lower (average $150-$350), and Thumbtack's real-transaction data ($228-$752, typical spend $415) also clusters below Angi's ceiling — both describe a typical, non-slab, non-emergency repair, which is why project_low_usd/project_high_usd uses Angi's own 'normal range' ($250-$850, corroborated by HomeAdvisor) to represent that everyday case, while range_low_usd/range_high_usd stretch further to capture the realistic full spread including slab leaks and complex behind-wall access. HomeGuide's independent severity tiers (small accessible $150-$500+, hidden/behind-wall $500-$5,000+, major disaster $2,000-$10,000+) confirm the same roughly-10x shape from simplest to worst case, though its 'major disaster' tier folds in water damage restoration beyond a pipe repair alone and isn't used for the headline range. by_type mixes HomeGuide's location-based breakdown (accessible, behind-wall) with HomeAdvisor's slab-leak figure and Angi's burst-pipe/main-water-line figures, each individually cited in sources. Figures generally cover diagnosis and the pipe repair itself; drywall/ceiling patching, flooring restoration, and mold remediation are commonly quoted as separate line items across all five sources.
