Slab Leak Detection & Repair — Prosper, TX
Slab Leak in Prosper?
Fix It Right.
The First Time.
Prosper sits on Blackland Prairie clay — one of the most expansive soils in North Texas. Homes from the 1960s–1980s era have copper supply lines that have been flexing under this soil movement for decades. When a slab leak develops, the repair method matters as much as the repair itself.

Why Prosper Has Slab Leaks
The Geology Behind the Problem
Prosper's older west-side neighborhoods have some of the oldest housing stock in Collin County. Homes built in the 1960s and 1970s near historic downtown Prosper have copper supply lines that have been under Blackland Prairie clay stress for 50 to 60 years. These properties see the highest slab leak frequency in the city. Understanding the cause is the first step to choosing the right repair — and making sure it does not happen again.
Clay expands when wet
Blackland Prairie clay swells significantly during rain and wet seasons, pushing upward and laterally against slab foundations throughout Prosper.
Clay contracts in drought
During dry North Texas summers, the clay contracts sharply — sometimes several inches — creating foundation movement in the opposite direction.
Copper lines flex with every cycle
Copper supply lines embedded in the concrete slab flex with every expansion and contraction cycle. Over 1960s of cumulative stress, micro-fractures develop in the pipe walls.
Micro-fractures become breaks
The fractures progress to full breaks. Water escapes under the slab, eroding soil and creating conditions for further foundation movement — making early detection critical.
Signs of a slab leak in your Prosper home? Warm floor spots, running water sounds when everything is off, simultaneous whole-house pressure loss, or unexplained water bill increases all point to a slab leak. Call for electronic detection before any concrete is touched.

The Meter Test — Five Minutes, No Cost
Before calling anyone, do this test. It confirms whether your supply system has an active leak in five minutes.
Turn off everything
Shut off every fixture, faucet, appliance, ice maker, and irrigation zone. Nothing should be drawing water.
Locate your water meter
It is in a box in the ground near the street in front of your Prosper property. Lift the cover and look at the dial or digital display.
Watch for 15 minutes
If the low-flow indicator (a small triangle or star) moves, or the dial advances at all with everything off, water is escaping from your supply system.
Call us with your result
A moving meter with everything off confirms an active supply leak. Tell us what you saw and we walk you through the next steps.
Other Signs to Watch For
Any of these alone or in combination suggest a slab leak in your Prosper home:
- Warm or hot spots on tile or hardwood floors
- Sound of running water when all fixtures are off
- Unexplained increase in your monthly water bill
- Simultaneous pressure drop at every fixture
- Moisture, mold, or mildew at baseboards
- Cracks appearing in walls or floors
- Foundation settling or uneven floors
Meter moving with everything off? Call us. Electronic detection locates the break before any concrete is disturbed.
Call (469) 327‑0831Three Repair Methods
The Right Repair for Your Prosper Home
Slab leak repair is not a single method. The right approach depends on the break location, your home's construction, your flooring, and how many prior slab leaks you have had. We explain all three options and recommend the right one after detection is complete.
$1,200–$2,500
Direct Slab Access
We cut or core-drill the slab at the break point, make the repair, and patch the concrete. Fastest and least expensive. Best for utility areas, tile floors, and situations where speed and cost are the priority. Interior flooring above the break point must be replaced.
$2,500–$5,000
Tunneling
We dig horizontally under the foundation from outside the home to reach the break without disturbing interior floors. Preferred in Prosper homes with original hardwood, period tile, or high-value stone. The cost premium is often offset by eliminating interior floor replacement costs.
$3,000–$8,000
Full Line Reroute
New PEX supply lines run through walls and attic, removing them from the slab environment entirely. The permanent solution for Prosper homes with two or more prior slab leaks. Eliminates future slab leak risk on rerouted lines completely.
$200–$450
Detection Only
Electronic, acoustic, and thermal detection to locate the break before any repair decision is made. Written report with break location, method findings, and repair options. Formatted for homeowner's insurance submission.
Financing Available — Ask about payment options on qualifying slab leak repairs and installations when you call.
Financing available on all slab leak repair methods in Prosper. Do not let cost be a reason to delay fixing an active slab leak — the longer it runs, the more expensive the total repair becomes from secondary water damage and foundation erosion.
Call (469) 327‑0831The Detection Process
Electronic Detection First. Always.
The most expensive mistake in slab leak repair is starting work without knowing exactly where the break is. We use three detection methods together before any repair decision is made.
Pressure Isolation Testing
Isolates which section of the supply system has a pressure loss — hot or cold, which zone, which branch. Narrows the search area before acoustic work begins and rules out surface leaks as the source.
Acoustic Amplification
Sensitive microphones detect the sound signature of water escaping under pressure through the concrete slab. Pinpoints the break location to within inches across the slab surface without disturbing anything.
Thermal Imaging
Identifies temperature differentials on floor surfaces caused by warm water leaking beneath. Adds a third data point for hot supply line breaks and confirms acoustic findings before recommending a repair method.
Written Location Report
Every detection job produces a written report with the exact break location mapped to your floor plan, methods used, findings, and repair options with itemized estimates for each.
Insurance Documentation
Before-and-after photos on every detection and repair job, formatted for submission to your homeowner's insurance company. Some Prosper policies cover slab leak damage — document everything first.
Post-Repair Pressure Test
After every repair, we pressure test the system to verify the break is resolved before we leave. You receive written confirmation that the supply system holds pressure at specification.

Prosper City Profile
Large Newer Homes and Complex Systems
Prosper homes tend to be large and relatively new, and size changes the plumbing picture. Two water heaters instead of one, hot water recirculation loops, long runs to distant bathrooms, and extensive irrigation are all common here. More system means more points of failure, and it also means a leak can run longer before anyone notices it.
Recirculation loops in particular deserve attention. They keep hot water available instantly, but they also mean hot water is moving through the lines constantly rather than intermittently. That accelerates wear on the hot side, including on any portion of the loop running through or under the slab.
Hard water compounds all of it, scaling two water heaters instead of one and working on higher-end fixtures that cost more to replace. Lakes of Prosper, Star Trail, Windsong Ranch, Gentle Creek Estates, and the communities along Preston Road are where we work most.
