Slab Leak Repair in San Diego

Protect Your Home’s Foundation with Expert Slab Leak Solutions

Stop Hidden Slab Leaks Before They Destroy Your Home

Slab leaks are more than just a plumbing issue — they’re a serious threat to your home’s foundation, floors, and even your family’s health. At LGE Prime Plumbing, we specialize in finding and fixing under-slab leaks quickly and precisely, using advanced tools that protect your property and save you thousands in potential repairs. As a trusted, family-owned San Diego company, we’re here to give you honest answers and dependable slab leak solutions that last.

Signs You Might Have a Slab Leak

Slab leaks often start quietly, hiding under your home’s concrete foundation for weeks or even months before showing obvious damage. Catching the warning signs early can save you from expensive repairs down the line and we often start with precise leak detection to ensure we’re addressing the right problem.

 

  • Warm or damp spots on your floor (especially if it’s a hot water line leaking)

  • Sudden spikes in your water bill with no extra use

  • Cracks forming in walls, floors, or your foundation

  • The sound of running water when no faucets are on

  • Mildew, musty odors, or unexplained moisture

 

If you’ve noticed any of these, don’t wait. Slab leaks won’t fix themselves — and the longer you wait, the more your foundation, flooring, and wallet could suffer.

Don’t Let a Slab Leak Destroy Your Foundation

A slab leak can quietly crack your foundation, warp your floors, and lead to mold that threatens your family’s health. We use advanced leak detection to find the problem fast and stop damage before it gets worse.

How We Detect & Repair Slab Leaks

Finding a slab leak isn’t about tearing up floors at random. At LGE Prime Plumbing, we use advanced, non-invasive tools to pinpoint leaks under your slab foundation with precision — saving you from unnecessary damage and extra costs.

  1. Use advanced detection tools: Thermal imaging, acoustic listening devices, pressure tests, and moisture meters help us locate the exact leak point under your concrete.
  2. Verify and plan: We’ll confirm the leak source, show you what we found, and go over all your options — from direct pipe repairs to reroutes that avoid digging up your entire floor.
  3. Professional repairs: Whether it’s a targeted fix or a partial reroute, we handle the work cleanly and efficiently to restore your plumbing and protect your foundation.
  4. Test : After repairs, we thoroughly pressure test your system.

What Happens If You Ignore a Slab Leak?

A small leak under your slab might seem harmless at first — but over time, it can quietly wreak havoc on your home. Ignoring a slab leak risks far more than higher water bills.

 

  • Foundation cracks: Water erodes soil under your slab, leading to shifting and dangerous cracks.

  • Mold & air quality issues: Hidden moisture creates the perfect environment for mold growth that can impact your family’s health.

  • Skyrocketing water bills: Even a small under-slab leak can waste thousands of gallons a month.

  • Potential electrical hazards: Water spreading near wiring or outlets is a major safety concern.

 

Don’t wait until minor signs become major structural damage. The sooner you fix a slab leak, the more you’ll protect your home — and your wallet.

How We Fix Slab Leaks: Your Repair Options

Every slab leak is different. That’s why we tailor our repairs to fit your home’s needs and minimize disruption. Here are the most common methods we use:

 

  • Direct spot repair: If the leak is easy to reach, we can open a small section of the floor and fix the pipe directly.

  • Pipe rerouting: For homes with aging pipes or multiple leaks, we often reroute water lines through walls or ceilings to bypass the slab entirely.

  • Whole home repipe: If slab leaks keep popping up or your plumbing is failing throughout, a full repipe may be the smartest long-term solution.

Is It Time for a Whole Home Repipe?

If your home has had multiple slab leaks or you’re dealing with low pressure and constant pipe problems, it might be time to look at a whole house repipe. This permanent solution replaces failing lines with modern, durable materials — giving you peace of mind for decades to come.

FAQs

Slab Leak FAQs

A slab leak happens when pipes beneath your home’s concrete foundation crack or burst. If ignored, it can cause structural damage, mold growth, and high water bills.

Signs include warm spots on the floor, unexplained water pooling, cracks in walls or flooring, and a sudden increase in your water bill.

Depending on the damage, repairs may involve spot repair on the affected pipe, rerouting the water line, or repiping the system to prevent future leaks.

Not always. In many cases, we can reroute or bypass the leaking pipe, minimizing damage to your home’s flooring and foundation.

Coverage depends on your homeowner’s insurance policy. In many cases, the damage caused by the leak is covered, but the actual pipe repair may not be. We can provide documentation to help with your claim.

Most slab leak repairs can be completed in one to two days, depending on the severity of the leak and the repair method required.
