Slab Leak Repair

A slab leak is a leak that occurs in the water lines that run under concrete, most commonly under the foundation of a home. Slab leaks need immediate repair because if they’re left alone, they can compromise the integrity of your home’s infrastructure.

As you can imagine, it’s extremely difficult for a homeowner to identify the need for leak repair under their foundation, much less perform those necessary repairs. If you encounter any of the warning signs of a slab leak, including a sudden rise in water bills, a drop in water pressure, unexplained puddles or warping in your floor, or even the growth of mold and mildew, you need a professional who can diagnose the problem and address it before it gets worse.

Homeowners in Riverside County can count on Guardian Plumbers to find and repair slab leaks in their foundation in a timely manner, without causing further property damage. Contact us today to learn more or receive an estimate.

Frequently Asked Questions About Water Leak Repair

As water leak repair experts serving Riverside County and the surrounding region since 2010, we often get asked a few specific questions about pipe leak repair. Here are the most common:

How can you detect a leaking pipe?

Checking the water meter when no water is being used inside or outside the house can help to detect a leaking pipe. If the indicator on the meter is moving when no water is flowing, it’s a sign of a leak somewhere in the system. It’s also a sign you need to call a plumber for an inspection.

How can you fix a leaking pipe behind a wall?

Fixing a leaking pipe behind a wall can sometimes require cutting into the wall and identifying the specific source of the leak. Depending on the type of pipe your home is built with, specific equipment and training is needed to actually make the repair.

How can you find a leaking water pipe under concrete?

While only a professional inspection will reveal the exact nature of the problem, you can typically spot a potential leaking pipe under concrete by looking for a few common warning signs.

  • Water pressure suddenly drops
  • Smell of mold or mildew
  • Water heater is working nonstop
  • Warm spots under the floor that don’t go away
  • Warped flooring

If you notice any of the above, the team at Guardian Plumbers has the experience, skill, and equipment to investigate and get to the root of the problem. We’re available 24 hours a day, so don’t hesitate to give us a call at the first sign of trouble.
