Slab Leak Detection & Repair in San Dimas, CA

Preventing Damage to Your Property

A slab leak is a plumbing leak in the water supply pipes running below your concrete slab. This is the area that supports the rest of the structure. Slab leaks can be difficult to detect and repair because of the concrete and other materials in the way. If you are experiencing a leak in your plumbing and aren’t sure where the leak is located, give us a call for slab leak detection and repair in San Dimas, CA.

How Is a Slab Leak Detected?

A slab leak is a water leak that occurs underneath the concrete slab foundation of a building. Detecting a slab leak can be challenging because it's not visible, but there are several signs and methods to identify one:

  • Water Bills: A sudden increase in your water bill without a corresponding increase in water usage can indicate a leak, possibly under the slab.
  • Water Meter: Turn off all water sources in your home and check your water meter. If the meter continues to run, it could indicate a leak.
  • Visual Signs: Look for cracks in your walls or flooring, especially if they appear suddenly. Also, keep an eye out for moisture or mold growth on floors or walls.
  • Warm Spots: If the leak involves hot water, you may notice warm spots on the floor.
  • Sound: Listen for the sound of running water when no fixtures are in use.
  • Pressure Test: A plumber can perform a pressure test to check for leaks in the plumbing system. This involves pressurizing the system and monitoring for any pressure drop, indicating a leak.
  • Infrared Technology: Some plumbers use infrared cameras to detect temperature changes in the flooring, which can indicate the presence of a leak.
  • Electronic Leak Detection: Specialized equipment can be used to listen for the sound of water escaping through the pipes under the slab.

Once a slab leak is detected, it's important to address it promptly to prevent further damage to the foundation and surrounding structures.

How Do Slab Leaks Occur?

Plumbing leaks can occur for a number of reasons. An old pipe may have developed a crack, or some type of wear and tear may have occurred. Other causes may include an improper installation or a shifting foundation. Regardless of the cause, a slab leak will cause the same type of damage to your property as a standard water leak. The water can seep into the concrete and cause it to weaken. It can also drive mold and mildew growth as well as cause the flooring to warp and crack.

Common signs of a slab leak include:

  • Water stains on the flooring or walls
  • Mold and mildew growth
  • Cracks in the flooring or walls
  • Damp or musty smells
  • The feeling of the floor being spongy or soft
  • A sudden increase in your water bill

The gentleman who answered the phone at 7 am was so friendly, quick, and efficient in getting me on the books. He had a technician over to check out the leak under my sink within 5 hours and accommodated my work schedule.
Sokun S.
Working with Alpine has been amazing. They were very responsive and the tech, Tom was awesome and very easy to talk to. They were very professional and did not push any additional unnecessary work, as some would. I will work with them again!

David is the one who helped us replace the water pressure regulator. David was really professional and didn’t try to scare us with some serious outcome if we don’t do this do that. David also replaced two fill valves for us as a courtesy.

The easiest plumbing repair call I have ever had. I messaged Alpine on Yelp and within 1 minute I got a response. I was lucky enough that their technician Matt was finishing up a job and was around my neighborhood.

Outstanding service! Quick response. Checked our commercial water heater within a couple of hours! Vincent and his coworker were informative and professional! Wish I could give more stars!!

Highly recommend Alpine Plumbing. Michael performed routine maintenance on my water heater and discovered it had been improperly installed. He was able to correct most of the problem in just a few minutes.
