Slab Leak Repair in MD, PA, & WV

A slab leak is one of the most serious plumbing problems a homeowner can face, especially in areas like Hagerstown, Frederick, Chambersburg, and Martinsburg, where many homes sit on older concrete foundations and experience seasonal soil movement. Because a slab leak forms beneath your home’s concrete slab, you rarely see the problem.

Larry & Sons Plumbing, Heating, Cooling & Electrical has protected local homes since 1960, delivering fast slab leak repair backed by a satisfaction guarantee and our lifetime repair guarantee. When water threatens your foundation, you need a team that responds immediately, accurately locates the issue, and respects your home every step of the way.

Contact Larry & Sons now to book professional slab leak repair in MD, PA, & WV.

What Is a Slab Leak?

A slab leak occurs when a water or sewer line beneath your home’s concrete foundation breaks, cracks, or corrodes. Because the plumbing sits under thick concrete, these leaks stay hidden until the symptoms become impossible to ignore. Homes throughout MD, PA, and WV experience slab leaks for many reasons, including aging pipes, soil movement, high water pressure, and chemical reactions between metal pipes and the surrounding soil.

Slab leaks require specialized tools and expertise. One wrong cut or misdiagnosis can damage your foundation, increase repair costs, or make the issue worse. That’s why homeowners depend on Larry & Sons for accurate leak detection and long-term repairs.

Warning Signs of a Slab Leak

Because you can’t see a slab leak directly, it’s important to recognize the early signs before water causes widespread damage. Common indicators include:

  • Unexplained increases in your water bill
  • Hot or warm areas on your floor
  • Water pooling around the foundation
  • Damp or musty indoor odors
  • Cracks appearing in floors or walls
  • Mold growth in previously dry areas
  • Water meter moving even when fixtures are off

If you notice any of these symptoms, call Larry & Sons right away. Same-day service is available, and our uniformed plumbers arrive with the tools needed to diagnose the problem on the spot.

Dangers of Ignoring Hidden Leaks

Slab leaks only get worse with time. When water continually escapes beneath your foundation, it can weaken the concrete, cause soil erosion, and increase pressure on flooring and support structures. Homeowners who wait too long often face:

  • Foundation cracking or settling
  • Warped or buckling floors
  • High humidity and mold growth
  • Damage to walls, cabinets, or furniture
  • Major structural repairs costing thousands

Addressing a slab leak early is far more affordable than restoring a damaged foundation later.

Slab leaks require precision, and our team takes a careful, minimally invasive approach. Every service call includes:

Frequently Asked Questions

Slab leaks can occur for several reasons, including pipe corrosion, high water pressure, shifting soil, poor installation during original construction, or long-term wear on older plumbing materials. Homes in MD, PA, and WV often experience soil movement and seasonal temperature changes, which can put pressure on underground pipes.
Licensed plumbers use specialized tools such as acoustic listening devices, pressure gauges, and thermal imaging cameras. These allow us to locate leaks beneath the concrete slab without tearing up flooring or damaging the foundation.
Depending on the location and condition of the pipe, we may reroute plumbing lines around the slab or use epoxy coating inside the pipe. In other cases, cutting into the slab is necessary to access and repair the leak directly. We always choose the least invasive and most cost-effective approach.
We provide 24/7 emergency service for urgent plumbing issues, including slab leaks. When water threatens your foundation or indoor air quality, our team responds quickly with the tools needed to stop the damage and begin repairs immediately.

The company scheduler was very helpful and got us a same day appointment. Matt, the technician was very prompt and professional and even provided advice on the issue. The price was reasonable even though the technician traveled from Maryland to our home in Martinsburg WV. I would recommend Larry and Sons for plumbing repairs to anyone.
