What Is a Slab Leak?
Many homes in Lancaster are built on concrete slab foundations, where water and sewer lines run underneath the structure. A slab leak happens when one of those pipes cracks or corrodes, allowing water to escape into the soil below.
Because the plumbing is buried, these leaks can go unnoticed for weeks or months. Over time, moisture seeps upward, weakening the concrete, damaging the flooring, and encouraging mold growth.
Older homes in neighborhoods like East Petersburg, Landisville, or Lititz are especially prone to slab leaks because their copper piping can wear thin over the decades. Even newer homes can develop leaks if water pressure is too high or if the ground shifts after heavy rain.
Warning Signs of a Slab Leak
A slab leak doesn’t announce itself, but it does leave clues. Keep an eye out for:
- Hot spots on the floor: A warm patch under tile or carpet often means a leaking hot water line.
- Unexplained water bills: If your usage suddenly spikes but your habits haven’t changed, water may be escaping under the slab.
- Running water sounds: Hearing water movement when no taps are on? That’s a red flag.
- Cracks in flooring or walls: Expanding moisture can push up on your foundation.
- Mildew or damp smells: Persistent humidity in certain rooms can signal a leak below.
- Low water pressure: Even a small leak can affect your home’s flow rate.
How Slab Leaks Are Detected
Detecting a leak beneath several inches of concrete takes experience and the right technology. Our plumbers use acoustic listening devices, thermal scanners, and moisture detection meters to find the exact location of the leak without digging.
Instead of tearing up your floor or guessing at the source, we can isolate the issue within inches. This precision allows us to create a targeted repair plan that saves time, protects your flooring, and keeps costs transparent.
You’ll always get upfront pricing and clear communication before any work begins; that’s part of what sets Neffsville apart.
Repair Options for Slab Leaks
Once the leak is found, our team will explain the best repair approach based on your home’s plumbing layout and the severity of the damage.
- Direct access repair: For a single small leak, we carefully open the slab at the leak site, repair or replace the section of pipe, and restore the area cleanly.
- Rerouting: If the damaged pipe is in a difficult spot or multiple leaks are found, we’ll reroute the water line through walls or ceilings, avoiding the slab entirely.
- Epoxy pipe lining: In some cases, we can seal the inside of your existing pipes with a durable epoxy coating, repairing the leak without excavation.
We’ll walk you through each option and help you choose what makes the most sense for your home, your budget, and your long-term peace of mind.

Frequently Asked Questions
What causes a slab leak?
Most slab leaks are caused by aging pipes, corrosion, or shifting soil beneath your home. Lancaster’s mix of clay and loam soils expands and contracts with moisture, putting stress on buried pipes. High water pressure and poor installation can also contribute to leaks over time.
How do plumbers locate slab leaks?
Our plumbers use non-invasive technology like acoustic listening equipment and infrared imaging to detect temperature changes and water movement.
Will slab leak repair damage my floors?
Our goal is to repair the pipe while preserving your flooring. In many cases, we can access the damaged line through a small, localized area or reroute the pipe entirely. When we do need to open the slab, we restore the area cleanly after the repair.
How can I prevent future slab leaks?
Regular plumbing maintenance helps catch small leaks before they grow. Also, keeping your water pressure regulated and installing a water softener can help extend the life of your pipes.
Does homeowners insurance cover slab leaks?
Coverage depends on your individual policy. Many insurance plans cover damage from sudden or accidental leaks, but not long-term corrosion. If you experience a slab leak, our team can provide documentation for your insurance claim and help you understand your options.
