Warning Signs of a Slab Leak

Slab leaks often develop slowly and can go undetected for months. Catching one early can limit damage to your foundation, flooring, and walls. Watch for these indicators:

Signs your home may have a slab leak:

• Unexplained water bill spike with no change in household usage
• Sound of running water when every fixture in the home is off
• Warm or hot spots on the floor, which often point to a hot water line break under the slab
• Damp, wet, or buckling flooring on ground-level floors
• Cracks in walls, floors, or the foundation that appear or widen without an obvious cause
• Mold, mildew, or musty odors concentrated near floor level
• Low water pressure throughout the home that has no other explanation

What Causes Slab Leaks in Richmond Homes

Richmond’s seasonal temperature swings cause pipes to expand and contract repeatedly, placing stress on older or poorly maintained plumbing lines. The area’s substantial annual rainfall can also increase moisture and hydrostatic pressure around a home’s foundation. Several additional factors contribute to under-slab pipe failure:

• Pipe corrosion in copper or galvanized steel lines, common in older homes
• Abrasion from pipes rubbing against concrete or gravel beneath the slab, which gradually wears through pipe walls
• High or fluctuating water pressure that stresses joints and connections under the foundation
• Soil movement and settlement that shifts or cracks pipes below grade
• Poor original installation, including improperly wrapped pipes or incorrect pipe sizing

Non-Invasive Slab Leak Detection

Before any concrete is opened, our technicians pinpoint the exact leak location using diagnostic equipment. Confirming the location first reduces the physical footprint of the repair and can limit disruption to your home.

Acoustic Leak Detection

High-sensitivity acoustic sensors detect the sound frequency of water escaping a pressurized pipe through concrete. By mapping sound variations along the pipe run, our technicians identify the failure point without cutting into the slab.

Infrared Thermal Imaging

Thermal imaging cameras map temperature anomalies beneath floors and behind walls. Hot water line failures show as concentrated warm zones. Cold water leaks produce corresponding cool signatures. Neither method requires moving furniture or cutting flooring during the diagnostic process.

Video Pipe Inspection

For a direct look inside the line, we use camera inspection equipment to assess pipe condition, confirm failure points, and evaluate whether the surrounding pipe material calls for a targeted repair or a broader solution.

Slab Leak Repair Options

Once the leak is located, the right repair method depends on pipe material, pipe age, leak location, and the extent of any corrosion. Our technicians assess all of these factors and recommend the approach that addresses the problem with the least unnecessary disruption.

Direct Access (Spot) Repair

For a single, localized failure, we open a small and precisely targeted area of concrete, repair the damaged pipe section, and restore the surface. This is the most straightforward option when the rest of the line is in good condition.

Pipe Rerouting

When concrete access is impractical or the damaged section is difficult to reach, we run a new supply or drain line through walls, the attic, or another accessible path. This bypasses the problem area entirely without requiring extensive concrete work.

Repiping

Homes with aging pipe material or multiple failure points may benefit from replacing the entire pipe run. Repiping can help reduce recurring under-slab leaks rather than addressing them one at a time.

Epoxy Pipe Lining

For certain drain or sewer line failures, an epoxy liner can be inserted and cured inside the existing pipe, sealing the leak from the inside with no digging required. Our technicians can confirm whether this trenchless method suits the pipe material and leak type before recommending it.
