House Slab Water Leak Repair

A slab leak is one of the most serious plumbing issues a home can face because the problem starts under the concrete foundation where you cannot see it. When a leak develops under the slab, water begins to travel through the ground, weakening the structure and creating damage that spreads quietly over time. Our goal is to find the leak quickly, explain your options clearly, and repair the problem with as little disruption to your home as possible.

Common Signs of a Slab Leak

Slab leaks often show up through subtle changes at first. You may notice warm spots on the floor, higher water bills, low water pressure, or the sound of running water when no fixtures are on. Floors can begin to warp or feel damp, and in some cases you may see cracks in walls or flooring as the ground shifts. If anything feels unusual, it is worth having us take a look before the issue worsens.

What Causes a Slab Leak

Several conditions can lead to a leak under the slab. Older copper pipes can corrode over time, especially if the soil is abrasive or moisture rich. Pressure changes, shifting soil, or improper installation can also cause small pinholes to form. Once the line weakens, water escapes and begins to move through the ground, which is why early detection matters.

How We Detect a Slab Leak

We use specialized equipment to pinpoint leaks without tearing up your floors. This includes listening devices, pressure testing, and tracing techniques that help us determine the exact location of the problem. The goal is accuracy so we can access the leak with the least amount of disturbance to your home. Once we identify the source, we walk you through the findings and explain the next steps.

Options for Slab Leak Repair

Depending on where the leak is located and the condition of the piping, you have a few options. Spot repair involves opening the area above the leak and repairing the damaged section of pipe. In some cases, rerouting the line is the better long term solution because it avoids the slab entirely. If the piping system is older or showing widespread wear, repiping may be recommended to prevent future leaks. We explain each option honestly so you can choose what works best for your home and budget.

If you suspect a slab leak, reaching out early can prevent major damage and save you from costly structural repairs.
