Trusted Slab Leak Repair for Hidden Plumbing Problems
A leak beneath your home’s foundation can be difficult to spot and even more difficult to ignore once the signs appear. Marathon Plumbing provides professional slab leak repair in Southeast Texas for homeowners experiencing unexplained moisture, warm or damp flooring, low water pressure, or other signs of an underground plumbing problem. Our experienced plumbers work to identify the source of the leak and determine the appropriate repair approach for your home.

Don’t Let a Hidden Leak Affect Your Home
A plumbing slab leak occurs when a water line beneath a concrete slab develops a leak. Because the damaged pipe is out of sight, homeowners may notice indirect warning signs before they see actual water. Unexplained increases in water usage, damp areas, the sound of running water, cracked flooring, or changes in water pressure can all warrant further investigation.
Early attention can make a difference. A persistent leak beneath a slab can allow water to continue accumulating where it should not. Marathon Plumbing evaluates the symptoms and plumbing system to help determine whether a slab leak is present and where the problem may be located.
Under Slab Leak Repair With a Careful Approach
Under slab leak repair requires more planning than an ordinary plumbing repair because the affected pipe is located beneath a concrete foundation. The repair method depends on factors such as the location of the leak, pipe condition, accessibility, and the overall layout of the plumbing system.
Marathon Plumbing focuses on identifying the problem before recommending a solution. Depending on the circumstances, repair work may involve accessing the affected section or exploring other practical options. We explain the work involved so you know what to expect before the repair begins.
Protect Your Plumbing and Foundation
A slab leak can affect more than your water bill. Continued moisture beneath a home can create additional concerns if the underlying plumbing problem is left unresolved. Foundation leak repair may be part of addressing a broader issue when water from a plumbing leak is affecting areas around the foundation.
With more than 50 years of combined experience among our team members, Marathon Plumbing brings knowledgeable service, upfront pricing, and practical options to every project.
