Burst Pipe Under Slab & Slab Leak Repair Services

Sub-slab pipe failures occur when pressurized copper supply lines buried beneath concrete foundations corrode, shift, or rub against aggregate rocks. Left unaddressed, slab leaks erode foundation soil, cause structural heaving, and spike water bills dramatically.

Part of our 24/7 Emergency Burst Pipe Repair solutions. For immediate dispatch call (855) 499-4130.

Professional Repair Methods

Acoustic frequency listening discs and nitrogen pressurization to pinpoint sub-slab ruptures without indiscriminate digging.
Direct concrete jackhammering access for targeted spot repairs on single-point ruptures.
Overhead PEX rerouting through attic or wall framing to bypass abandoned sub-slab copper lines permanently.
Trenchless CIPP relining where pipe geometry permits non-invasive structural sleeving.

Estimated Repair Pricing

Typical investment for this specific repair: $1,200 – $4,500 (depending on spot repair vs. overhead line reroute). For national averages and cost-of-living adjustments, visit our detailed pricing guide.

When to Call a Professional

Do not attempt makeshift epoxy putty or duct tape fixes on pressurized water lines. Household water pressure (50 to 75 PSI) will rupture temporary patches, causing catastrophic flooding. Contact a licensed technician to install code-compliant fittings.
