A slab leak in your Folsom, Rancho Cordova, or Sacramento home is one of the most damaging plumbing problems you can face — and one of the easiest to ignore until it causes thousands of dollars in damage. Plumbing Care Inc. uses non-invasive electronic leak detection, thermal imaging, and line tracing to find slab leaks fast and repair them with minimum concrete disruption. Same-day service is available across Sacramento County.
What is a slab leak?
A slab leak occurs when a copper, PEX, or galvanized water line beneath your home’s concrete foundation develops a pinhole or crack. Hot-water lines fail more often than cold because heat accelerates corrosion. Homes built in Folsom, Rancho Cordova, and the broader Sacramento region between the 1970s and 1990s are especially vulnerable — many were plumbed with thin-wall copper that has now reached the end of its service life.
Common signs of a slab leak
- Warm or hot spots on the floor — often on tile or vinyl over a hot-water leak
- Sound of running water when all fixtures are off
- Unexplained spike in your water bill — sometimes 2x or 3x normal usage
- Damp baseboards, carpet, or flooring with no visible source
- Mold or mildew smell emerging near interior walls
- Cracks in walls or flooring from soil shifting under the slab
- Reduced water pressure at fixtures throughout the home
- Constantly running water heater trying to keep up with the loss
Why slab leaks must be repaired immediately
Left untreated, a slab leak will saturate the soil beneath your foundation, lead to mold growth, rot wood framing, ruin flooring, and in severe cases shift the foundation itself. Insurance generally covers the water damage but not the leak repair — and many policies deny claims for leaks the homeowner “should have caught earlier.” Acting quickly protects both your home and your coverage.
How we locate and repair slab leaks
- Free phone triage — we walk you through how to confirm whether to shut off the main water supply while we dispatch a technician.
- Non-invasive electronic detection — our techs use acoustic listening discs, thermal imaging cameras, and pressurized gas line tracing to pinpoint the leak through the slab. Most leaks are located within a 12″ radius without breaking any concrete.
- Upfront flat-rate quote — you receive a written quote for the repair approach before any work begins.
- Choose your repair method:
- Spot repair — break a small section of slab, repair the leak, repour. Best for single isolated leaks in newer homes.
- Reroute / bypass — abandon the leaking line and run new PEX through walls or attic. No concrete work. Often the fastest, least invasive option.
- Whole-home repipe — if multiple leaks have occurred or the existing copper is failing systemically, a full repipe is the long-term solution.
- Pressure test and verification — every repair is pressure tested. We provide moisture readings and photos for your insurance claim.
Slab leak FAQs
How much does slab leak repair cost in Sacramento?
Most spot repairs range from $1,200 to $2,800 depending on access and slab thickness. Reroutes range from $1,800 to $4,500. Full repipes start around $7,500 for a 1,500 sq ft home. We provide upfront flat-rate quotes after detection.
Will my insurance pay for slab leak repair?
Most policies cover the resulting water damage and the cost of “access” (cutting and repairing the slab) but not the actual pipe repair. We provide documentation that helps maximize your claim.
How long does the repair take?
Spot repairs are typically completed in a single day. Reroutes take 1–2 days. Full repipes 3–5 days depending on home size.

Frequently Asked Questions
What is a slab leak?
A slab leak is a leak in the water supply or drain lines running under or through your home's concrete foundation. They often manifest as warm spots on the floor, unexplained water bills, or the sound of running water with no fixtures on.
Why are slab leaks so common in Folsom and Rancho Cordova?
Homes built between 1990 and 2010 in our area often used soft copper supply lines routed through concrete slabs. Combined with hard water, high static pressure, and expansive clay soils, these copper lines corrode and develop pinhole leaks.
Do you have to break the concrete to fix a slab leak?
Not always. In many cases we reroute the affected line through walls, ceilings, or the attic, avoiding all concrete work. When direct slab access is needed, we minimize the opening size.
How long does slab leak repair take?
Most single-line slab leak repairs are completed in 1 to 2 days. Full repipes to permanently eliminate slab leak risk typically take 2 to 4 days depending on home size.
How can I prevent future slab leaks?
Install a pressure-reducing valve to keep static pressure under 75 psi, add a whole-home water softener to slow copper corrosion, and consider a full PEX repipe if multiple slab leaks have already occurred.
