What Should I Do In Case of a Slab Leak

Dealing with a slab leak? A slab leak can sound like a worst-case scenario, but the truth is, with the right approach and a team of skilled and experienced plumbers, slab leak repair in Chula Vista doesn’t have to be a dreaded task. These types of leaks happen when the pipes beneath your home’s concrete foundation crack, burst, or corrode. Left unchecked, they can cause major water damage, mold growth, and even foundation issues.

Now, most homeowners aren’t exactly sure what happens after a slab leak is found. Does someone just start jackhammering the floor? Are your tiles getting ripped up? Is your house going to be a construction zone for weeks? Relax! We’re walking you through it all.

In this blog, we’ll break down what the slab leak repair process actually looks like so you know exactly what to expect and can make informed decisions every step of the way.

What to do if a slab leaks?

If you think you’ve got a slab leak, or you’ve already confirmed it, don’t wait. The longer water is leaking under your foundation, the more it can cost in structural damage. Here’s a step-by-step guide that will give you a clear idea of what to expect so you can stay in the know while your plumbers are getting their hands dirty.

Step 1: Confirming the leak

Before any work begins, a licensed plumber will verify that you’re actually dealing with a slab leak. This usually starts with a water pressure test or a meter check to confirm water loss when the system should be sealed. If the numbers don’t look right, they’ll bring in electronic leak detection tools—like thermal imaging or acoustic sensors—to pinpoint the source beneath the slab.

This detection phase is critical. You don’t want to go cutting into concrete unless you’re 100% sure where the leak is coming from.

Step 2: Evaluating the best repair method

Once the source is found, your plumber will walk you through the best repair options based on:

• The location of the leak
• The condition of the plumbing system
• The age of the home
• Your budget and timeline

There’s no one-size-fits-all fix here. What works for a newer home with PEX piping may not work for an older copper system showing signs of wear.

Step 3: The actual repair: three proven methods

There are typically three ways pros handle slab leak repairs. Let’s break them down.

1. Direct access repair

This is the classic approach: cutting through the concrete slab directly above the leak, fixing the damaged pipe, and patching the slab back up.

• Pros: It’s fast and straightforward if the leak is in an accessible spot.
• Cons: It’s invasive. You’ll likely need to repair or replace flooring afterward.

2. Pipe rerouting

In some cases, it makes more sense to abandon the old pipe and reroute new plumbing lines through walls, ceilings, or attics.

• Pros: Avoids tearing into your slab and prevents future slab leaks in that same line.
• Cons: Slightly more labor-intensive and may require opening up some drywall.

3. Pipe lining (epoxy coating)

For certain types of pipes (typically copper), plumbers can insert a liner or coat the inside of the pipe with epoxy resin to seal the leak.

• Pros: No demolition is needed. Great for isolated pinhole leaks.
• Cons: Not suitable for all types of pipe or extensive corrosion.

Step 4: Restoring the work area

After the plumbing is fixed, the focus shifts to putting everything back in place. If the slab was cut, your plumber will:

• Refill the hole with sand or gravel
• Pour new concrete to match the existing slab
• Smooth and level the surface

Depending on your flooring type—tile, hardwood, laminate—you may need to call in a flooring specialist for a perfect match.

Step 5: Final pressure testing & clean-up

Before calling it a day, your plumber will do a final pressure test to confirm the repair holds up under normal conditions. They’ll also double-check for any additional leaks and ensure everything is functioning as it should.

A good plumbing crew won’t leave a mess behind. Expect a professional cleanup, clear instructions, and peace of mind, knowing your leak is fully resolved.
