Slab Leak Detection & Repair

Many houses in Texas are built on clay soil. Years of weather and soil changes can cause the concrete foundation slab to move. The hefty concrete shifting exerts stress on the drain, sewer, drain, and water lines running beneath the foundation, causing them to leak- this water penetrates through tiny cracks in the foundation, destroying it in the process.

Slab leaks are dangerous as they may bring a significant amount of damage to the foundation and pose a health threat if not repaired sooner. Don’t forget the extra costs you incur for repair! If not inspected thoroughly, the leak may go unnoticed, resulting in severe damages and health hazards like mold and mildew, which are expensive to repair.

We have a team of reliable and experienced plumbing experts who efficiently locate and repair the slab leak regardless of their condition.

Our Slab Leak Detection Services

Don’t neglect regular pipe inspections and water heater maintenance. If your home is on a slab foundation, as most homes are, the pipes that run under the house and out can spring leaks or develop weak spots that fail in time. Regular slab inspections are a good idea for that reason. In addition, you may want to have an inspection in several cases:

  • When you suspect a foundation leak
  • Before selling your home
  • Buying a home
  • When you find waterlogged soil or smell sewage


You may also want an annual inspection of lines outside the house. Gas, sewer, and water lines can deteriorate and fail. Regular inspection can head off sewer backups, serious drain clogs, and gas leaks inside the homes.

Do you know the maintenance requirements of your plumbing system? Your sewer system? Your gas lines? A plumber will be able to advise you on maintenance and inspection schedules.  Regular maintenance and inspection work can prevent lots of plumbing problems, water leaks in particular.

Water Leaks


We use isolation test balloons and in-line camera equipment to locate sewer and drain leaks. We then place a test ball in the main sewer line filled with water at the exterior cleanout. We then monitor from the floor level to detect any water drops from leaking pipes. Dropping water signifies a leak. We then do Isolation testing and run a camera in the line to determine the exact location of the leak.


After locating the leak, we shall then repair it according to your preference. We consider the plumbing layout, house layout, slope, length, and depth of the lines to determine the best repair strategy during the repair. We have extensive experience in sewer slab leaks, and water line leaks to give you the best solution.

How Do We Detect Leaks on a Concrete Slab in Fisco, Texas?

There are two types of leaks; portable water leaks and drain leaks. Plumbing pipes are mostly placed beneath the concrete foundations. As time goes by, the lines might be damaged, causing leaks.

Several warning signs of a slab leak include:

  • Wet patches on hardwood floors.
  • Spike in the water bill.
  • Soiled carpets.
  • Water spots on ceilings.
  • A water heater that is always running.
  • Dips in carpeting around foundations and peeling paint near exterior walls.


Other signs include flooring cracks and damaged window frames. You can also look at the water meter movements with every faucet closed.

Signs of a Slab Leak

Slab leaks, especially sewer slab leaks, may be complicated to detect as they happen underneath the slab.

If you discover the following signs, be assured that you have a slab leak.

Spike in your water bill: A slab leak will cause your water to run 24/7, resulting in a higher water bill. If you notice an unusual sudden spike in your water bill, call our slab leak plumbers to come and establish the root problem and help you fix it immediately.

Reduced water pressure: Slab leak causes water to escape, reducing the water that runs in the pipe. This causes the water pressure in the line to drop. If you discover a decrease in your water pressure, it’s the perfect time to bring in our slab leak detectors.

Hot spots on your floor: A hot water line is prone to leaks. When the hot water leaks, it heats the concrete above it, making the floor hot and forming a hot spot. It is easier to detect the warm location on hardwood, tile, and linoleum floors. If you do notice hot spots on the floor, be assured that you have a leak.

Damaged or wet flooring: Water from a leaking slab penetrates small cracks and reaches your flooring. This water damages the floor in many ways depending on the type of flooring you have. Carpet flooring may feel damp and appear darker, while the floorboards in hardwood flooring may warp.

An unpleasant odor: Moisture from the leaking water may result in mold and mildew growth. The moisture can also be absorbed by the drywall, causing molds to grow. The development of the molds manifests itself as a musty odor. Whenever you see molds or smell an unpleasant odor, you should know that you have a slab leak.

Running water sounds: If you hear running water sounds even when all your taps are off, be assured that you have a slab leak. When this happens, switch off all fixtures, including the water heater, then proceed to the lowest level of your house. Pay close attention to detect any sounds of flowing water. Any moving water sound would indicate a water leak.

Pooling water: When a slab leak develops, water hovers in the slab before finding a way out. You might see a pool of water on the floor inside the house or see water tracing out of the slab foundation outside the home. Inspect your appliances for leaks. If not, then you have a slab leak.

Stains around sinks or other fixtures: Water seeping through cracks in concrete slabs causes dampness on walls and floors in the house, especially near plumbing fixtures like sinks and toilets. This wet area might be a sign of slab leaks.

A toilet that flushes frequently: If your toilet is frequently flushing than usual, it can be a sign of slab leak. These symptoms signify a drop in water pressure in the pipes.

What causes a slab leak?

Friction and Regular Wear & Tear

Regular slab shifting exerts friction to the water pipes damaging them in the process. Similarly, their expansion and contraction cause them to rub against the concrete slab, resulting in wear and tear. The pipes will soon start leaking water which penetrates the cracks in the foundation.

Nature of Water it Carries

Water with high acidity or alkalinity levels corrodes the pipes fast. To ensure this doesn’t happen, check the water’s PH level regularly that runs through your water line.

Poor Construction

Constructions that bend the pipes beneath them may cause them to leak sooner or later. Copper pipes are more susceptible to water abrasiveness; hence they leak easily if installed in the slab.

Shifting Soil

Weather changes may cause the soil beneath to shift. The impact may cause sewers and water systems to crack or tear, resulting in-slab leaks.

High Water Pressure

High water pressure causes wear out and corrodes copper pipes over time, especially in bends and where the pipes change directions.

Poor Materials/Workmanship

The use of inferior pipes and improper installation may result in defects that may cause slab leaks.

Are Slab Leaks Emergence

 A slab leak is a serious plumbing problem that needs to be taken seriously; otherwise, it will severely damage.

A slab leak can

  • Ruin floors and carpets. When water seeps into the structure, it saturates floors, cracks tiles and flooring, and soaks carpets.
  • Cause foul odors. A slab leak may cause a musty smell due to the growth of molds in the house.
  • Cause mold and mildew growth. Water that seeps due to slab leak is absorbed by the drywall, promoting the development of molds. The growth of molds is a health threat to you and your loved ones.


Besides causing damage to the inside of the house, the slab leak also damages the outside. Such damage may include

  • Damage to your home’s foundation. A foundation leak may weaken the structural composure of the concrete foundation and steel supports, compromising your foundation. The water pressure generated may cause the foundation to shift, resulting in cracks and collapse.
  • Damage to your yard. When the slab or pipes in your yard leak, the seeping water may flood and ruin your surrounding landscape. Pools, brick, concrete walkways or paths, and other landscape elements may be damaged by the leak under the slab.
