Slab Leak Repair in McKinney, TX
Locate the leak. Fix what's broken. Skip the headache
McKinney's Slab Leak Specialists
JMP Plumbing Services repairs slab leaks across McKinney — pinhole leaks in copper supply lines, separated joints, hot water line failures, and full repipes when the copper is too aged to spot-repair. We locate the leak first with electronic detection and pressure testing, then we make the smallest possible cut in your slab to fix it. No random jackhammering. No guesswork. Trip fee is waived when you move forward with the repair.
How We Repair Slab Leaks in McKinney
Electronic Detection First
Acoustic leak detection, pressure testing, and thermal imaging locate the leak to within a few inches before any concrete gets touched. You see the diagnosis. We confirm the location. Then we cut.
Smallest Cut That Solves It
Targeted slab access only where the leak is — not random demolition across your floor. Patch and finish included. We protect your flooring, contain dust, and clean up before we leave.
Permit-Pulled, Code-Compliant
Slab leak repairs that involve replacing supply line sections require City of McKinney permits. We pull every permit, schedule every inspection, and leave you with documented code-passed work on file.

WHY MCKINNEY HOMES GET SLAB LEAKS
McKinney's combination of soil, water, and home construction makes slab leaks common. Four factors drive most calls:
Slab-on-grade construction everywhere.
Almost every McKinney home — from Historic Downtown to Trinity Falls — sits on a concrete slab with supply lines running underneath. When those copper lines fail, water leaks under your floor instead of into a basement. You don’t see it until it spikes your bill or warps your flooring.
Aging copper supply lines.
Pre-2005 McKinney homes typically have copper supply lines installed when the home was built. Copper has a 20–40 year typical lifespan in slab applications. Pinhole leaks start appearing as the pipe walls thin. Once you have one, you’re statistically likely to have more.
Hard water from NTMWD
North Texas Municipal Water District water runs 14–16 grains per gallon. Over decades, calcium, magnesium, and chlorides accelerate copper degradation from the inside. The harder the water, the faster the pinhole leaks appear.
Expansive clay soil movement.
McKinney sits on clay that swells in wet seasons and shrinks in dry. Slab foundations shift slightly with the soil. Supply lines under the slab don’t always shift with it — they crack, separate at joints, or rub through their protective sheathing.

McKinney's Slab Leak Repair Process
Diagnostic Slab Leak Detection
For isolated pinhole leaks in copper lines with otherwise sound plumbing, we cut targeted slab access, replace the damaged section, and patch the floor. Fastest and lowest-cost option when the rest of your domestic water supply lines are still in good shape.
Slab Line Reroute
When the leak is in a hard-to-reach section, under a finished kitchen, or in a line that's likely to fail again, we abandon the under-slab pipe and reroute new PEX or copper above the slab — through walls, ceilings, or the attic. No more cuts in your floor for that line.
Whole-House Repipe
For homes with multiple slab leaks in 5 years, severely aged copper, or original galvanized/polybutylene supply, we replace the entire supply system with PEX or copper. Solves the problem permanently — most homeowners don't repipe a second time in their lifetime.

Frequently Asked Questions
Slab leak repair in McKinney typically runs $1,500 to $4,500 for spot repair, $3,000 to $7,000 for a slab line reroute, and $8,000 to $25,000 for a full whole-house repipe. Final pricing depends on leak location, flooring type, line accessibility, and slab condition. We give a flat quote after leak detection — before any concrete gets cut.
Common signs include an unexplained spike in your water bill, the sound of running water when no fixtures are on, warm spots on tile or hardwood floors, low water pressure, mildew or musty smell with no visible source, or hairline cracks appearing in your slab. Any one of these warrants a leak detection visit.
Electronic acoustic leak detection picks up the sound of water escaping through pipe walls. Pressure testing isolates which supply line (hot or cold) is leaking. Thermal imaging detects temperature differences for hot water line leaks. Together these methods locate the leak within inches before any concrete gets touched.
A spot slab leak repair typically takes 4 to 8 hours. A line reroute takes 1 to 2 days. A whole-house repipe takes 3 to 7 days depending on home size. Permit issuance from the City of McKinney can add 1 to 3 business days at the front end for repipes and major reroutes.
Most standard homeowner's policies cover the water damage caused by a slab leak (flooring, drywall, contents) but not the cost to repair the pipe itself or access the slab. Some policies offer "service line coverage" as an endorsement that does cover the repair. We provide full documentation — photos, detection report, invoice — for any insurance claim.
Spot repair cuts targeted access through the slab, replaces the damaged pipe section, and patches the slab. Reroute abandons the under-slab pipe entirely and runs a new supply line above the slab through walls or ceilings. Repair is faster and cheaper short-term. Reroute is more durable when the rest of that line is likely to fail.
Most isolated slab leaks can be spot-repaired or rerouted without a full repipe. Repipe becomes the right call when you've had two or more slab leaks in 5 years, your copper is over 40 years old, or detection reveals additional thin spots in multiple lines. The camera and pressure-test data tells us which path is appropriate.
Yes — very common. Almost every McKinney home is slab-on-grade with copper supply lines, and our hard NTMWD water plus expansive clay soil accelerates copper degradation. Slab leaks are routine in McKinney homes 20+ years old.
Untreated slab leaks cause flooring damage, slab erosion under the foundation, mold growth, structural foundation issues, and major water bill increases. A $2,000 spot repair caught early becomes a $20,000 foundation + flooring repair if ignored for a year.
Yes. Same-day leak detection is available in McKinney, Allen, Plano, and Frisco. Active emergency leaks get priority dispatch. Call 469-337-3725 before noon for best same-day availability.
