What Is a Slab Leak?

Many Georgia homes are built on a concrete slab foundation, with water supply lines running underneath or through the concrete. A slab leak happens when one of those lines cracks, corrodes, or wears through. Because the pipe is hidden under the floor, water can escape for weeks before anyone notices. It soaks into the soil, seeps up through flooring, or collects under the slab. Slab leaks can affect hot or cold water lines, and hot water leaks are often noticed first because they create warm spots on the floor. Left alone, a slab leak can cause flooring damage, mold, high water bills, and even shifting in the foundation.

Signs You May Have a Slab Leak

  • Warm or hot spots on tile, wood, or concrete floors
  • The sound of running water when every fixture is off
  • A water meter that keeps moving when no water is in use
  • Damp carpet, warped flooring, or cracked tiles with no obvious source
  • Cracks appearing in walls or the foundation
  • A water heater that runs constantly
  • Mold, mildew, or musty odors near the floor

Why Fast Slab Leak Repair Matters

A slab leak works quietly, and that’s exactly what makes it dangerous. While you go about your day, water is soaking the soil under your home, rising into your flooring, and feeding mold in places you can’t see. The longer it runs, the more expensive the fix becomes. Acting at the first sign of trouble protects far more than your water bill:

  • Protects your foundation from soil erosion and shifting caused by constant moisture
  • Saves your hardwood, tile, carpet, and subfloor from water damage
  • Prevents mold and mildew from taking hold beneath floors and inside walls
  • Stops the water and energy waste, especially from leaking hot water lines that keep your water heater running
  • Keeps the repair smaller, simpler, and far less costly
  • Gives you peace of mind that your home’s structure is sound

Slab Leak Repair Methods

There’s more than one way to fix a slab leak, and the right choice depends on where the leak is, the condition of your pipes, and your home’s layout. Here are the options we use most:

  • Direct access repair: we open a small section of the slab right above the leak, repair the pipe, and close it back up, which works best for a single, isolated leak
  • Rerouting: we abandon the leaking line under the slab and run a new one through walls, ceilings, or the attic, avoiding the concrete entirely
  • Repiping: when the pipes under your home are aging or have failed more than once, replacing the whole system prevents future slab leaks

Your plumber will explain which method fits your situation, why, and what each one costs, so you can make the decision with confidence.

How to Check for a Slab Leak Before You Call

A few simple checks can help you spot a possible slab leak:

  • Turn off every faucet and water-using appliance, then check whether your water meter is still moving
  • Walk barefoot across tile or hard floors and feel for unusually warm spots
  • Listen near the floor for running or hissing water when everything is off
  • Check whether your water heater is running far more often than normal

If any of these point to a leak, shut off your main water valve if water is visible, and schedule a professional inspection as soon as possible.

Spot Repair, Reroute, or Repipe?

If your pipes are in good condition and the leak is limited to one spot, a direct access repair is usually the most cost-effective fix. Rerouting makes more sense when the leak is under a hard-to-reach area, like a kitchen island or a finished floor you’d rather not disturb, or when the line under the slab is showing its age.

If you’ve already had one slab leak, it’s worth looking closely at the rest of your plumbing. Pipes of the same age and material often wear out on a similar timeline, so a second leak may not be far behind. In that case, rerouting or repiping can save you from repeated repairs. We’ll lay out each option with pricing so you can choose what’s best.

Common Causes of Slab Leaks in Loganville

Slab foundations are common across Loganville, and local conditions put real stress on the pipes beneath them. Georgia red clay expands when it’s wet and contracts when it dries out, which shifts the soil under your home through the seasons. Over time, that movement and other wear can damage buried lines. Here’s what we see most often:

  • Expanding and contracting clay soil that shifts and stresses pipes under the slab
  • Corrosion on older copper lines from contact with soil and concrete
  • Abrasion where pipes rub against concrete, gravel, or other pipes as water flows and they expand
  • High water pressure that strains joints and weak spots over time
  • Pipes that were kinked, dented, or poorly installed during construction

Slab Leak Repair in Loganville FAQs

Signs of a hidden water leak include a sudden high water bill, low water pressure, damp spots, stains, running water sounds, or musty smells. If you suspect a leak, call us for a professional inspection.
Repiping replaces old or failing pipes throughout your home. It’s often needed for aging galvanized pipes, polybutylene, frequent leaks, discolored water, or low pressure. We’ll inspect your system and recommend repair or full repiping.
We offer straightforward, upfront pricing with no hidden fees. Your technician diagnoses the issue and provides a clear price before any work begins, so you’ll know the cost upfront with no surprises on your bill.
Most repairs include a one-year labor warranty unless noted otherwise, with coverage up to 12 years in some cases. Parts and equipment include at least a one-year warranty, with up to 12 years on select systems.
Yes. We offer financing options for larger repairs and replacements, including promotions like 0% APR for 60 months with equal payments, plus rebates on qualifying equipment. Ask us about current offers when you schedule.
Slab leaks are often caused by soil movement, corrosion, abrasion against concrete or gravel, high water pressure, or pipes that were damaged during construction. In Loganville, expanding and contracting clay soil is a common contributor.
We use pressure testing to confirm which line is leaking, then acoustic listening equipment and thermal imaging to pinpoint the exact spot under the slab. That way, if we do need to open the concrete, the opening is small and right where the leak is.
A slab leak should be repaired as soon as possible. Even a slow leak can damage flooring, encourage mold, and weaken the soil supporting your foundation over time. If water is visibly spreading, shut off your main water valve and schedule service right away.
Not always. If direct access repair is the best option, we only open a small area above the leak. Rerouting the line through walls or the attic avoids opening the slab entirely, which is often preferred under finished flooring.
It depends on your policy. Some policies cover the damage a slab leak causes and the cost of accessing the pipe, but not the pipe repair itself. Check with your insurance provider, and we’ll gladly provide documentation of what we find.
Yes. If the pipes under your slab are aging or made of the same material, other sections may fail over time. That’s why we look at the overall condition of your plumbing and may recommend rerouting or repiping after a first slab leak.
