Slab Leak Detection & Repair

A slab leak can start small, but hidden water beneath your home’s foundation can lead to serious damage if left unresolved. Mastco Plumbing provides professional slab leak detection and repair for homeowners throughout Van Alstyne and surrounding North Texas communities.

Could You Have a Slab Leak?

Slab leaks can be difficult to spot because the plumbing is located beneath your home’s foundation. Knowing the warning signs can help you catch a problem before it leads to more extensive damage.

Warm Spots on the Floor

An unusually warm area on your floor may indicate hot water escaping beneath the slab.

Unexplained Increase in Your Water Bill

A sudden increase in water usage without a change in your household habits can be a warning sign of a hidden leak

Sound of Running Water

Hearing water when your plumbing fixtures are turned off may indicate a hidden leak beneath your foundation.

Cracks in Floors or Walls

Changes in your foundation or surrounding surfaces can sometimes accompany a significant plumbing leak.

Damp or Wet Areas

Unexplained moisture, damp flooring or water pooling can indicate water escaping beneath the slab.

Low Water Pressure

A leak in a pressurized water line beneath the foundation may affect water pressure throughout your home.

Think You May Have a Slab Leak?

Don’t wait for a small leak to become a major problem. Mastco Plumbing can help locate the source of the leak and explain your repair options.

How Do Plumbers Find a Slab Leak

Finding a slab leak isn’t always as simple as looking for visible water. The plumbing beneath your foundation can leak without leaving an obvious sign inside your home. Mastco Plumbing uses professional leak detection methods to help locate the source of the problem while minimizing unnecessary disruption to your home.

Electronic Leak Detection

Specialized equipment can help identify the location of hidden water leaks beneath your foundation without immediately resorting to invasive excavation.

Pressure Testing

Pressure testing can help determine whether a water line is losing pressure, which may indicate a leak somewhere within the plumbing system.

Pinpointing the Leak

Once the suspected leak location is identified, our team can evaluate the area and discuss the appropriate repair options with you.

What Causes Slab Leaks?

Slab leaks can happen for several reasons, including aging plumbing, corrosion, shifting soil and changes in water pressure. Over time, these conditions can weaken or damage the water line beneath your foundation.

Aging or Deteriorating Pipes

Older plumbing materials can deteriorate over time, increasing the risk of leaks beneath the foundation.

Corrosion

Corrosion can weaken the inside or outside of a plumbing pipe and eventually lead to a leak.

Shifting Soil or Foundation Movement

Changes in the soil around your home can place stress on underground plumbing and contribute to damaged or leaking lines.

Water Pressure

Excessive or inconsistent water pressure can put additional stress on plumbing components and water lines.

A slab leak doesn’t always have an obvious cause, and the source can’t always be determined without professional testing. If you’re noticing signs of a possible leak, an inspection can help identify the problem before additional damage occurs.

What Happens If a Slab Leak is Left Unrepaired?

Even a small slab leak can continue to waste water and cause problems beneath your home. The longer a leak goes undetected, the greater the potential for water damage and more extensive repairs.

Higher Water Bills

A hidden leak can continuously use water, causing your water bill to increase without an obvious change in your household usage.

Moisture and Mold Concerns

Persistent moisture can create an environment where mold and other moisture-related problems may develop.

Damage to Flooring or Walls

Water escaping beneath the foundation can eventually affect flooring, walls and other areas of the home.

More Extensive Plumbing Repairs

A leak that isn’t addressed can worsen over time, potentially turning a smaller repair into a more involved plumbing project.

If you suspect a slab leak, getting it investigated early can help you understand what’s happening and determine the appropriate next step. Mastco Plumbing can help locate the source and explain your repair options.
