What is a Slab Leak?

The “slab” is technically a massive, concrete block or “domino-like” cement like foundation upon which your entire house sits. A slab leak is a leak in one or more of the water lines running below the concrete floor of your home.

During the 1950’s, 60’s, 70’s and early 80’s, many homes in Southern California were built with a concrete slab foundation poured over galvanized steel water pipes (in the 50’s and 60s) and eventually copper pipes in the late 70’s and 80’s. Unfortunately, many problems can arise with plumbing systems buried under poured concrete. Over time rust builds up in the pipes and deterioration often occurs.  Many homeowners don’t realize they even have a slab leak until major problem occurs, flooding the home.

A slab leak is a serious plumbing issue that no homeowner really wants to ever experience. Regrettably, if you have a home built on slab, in time a leak or leaks will almost inevitably occur.  So it’s not a matter of if, but more of when.

What Causes Slab Leaks in Los Angeles, San Fernando Valley or Ventura County homes?

Slab Leak Repairs

Leak from a residential underground recirculation line.

The main water supply line, in any home pre 1965, is likely made of galvanized steel. If this fits your home’s description, in all likelihood the pipes are already corroded and rusted.  If the plumbing hasn’t been replaced yet, it will soon. Typically the life span of galvanized steel pipes is no more than 50 years.  If your pipes are made of copper, which replaced steel in the latter part of the 20th century because copper resists rust and corrosion, it was probably both thin and soft. Any dents, pits, imperfections in the copper pipe, over the years of water rushing through it, has caused the area of imperfection to wear down and create a pinhole leak.  Additionally If your concrete slab has shifted over the years (Southern California is earthquake country after all) it could cause stress on the pipe and cause it to crack and leak as well.

Signs You May Have a Slab Leak in your Los Angeles, San Fernando Valley or Ventura County home

Since your water lines are below the slab, detecting leaks is very difficult. This said, there are some things that a perceptive homeowner can look and listen for which may indicate if there is a slab leak problem. If you can detect or identify any of the issues below, call FLOOD BROTHERS PLUMBING IMMEDIATELY at 855.840.7800 or click for an inspection before you have severe water damage: 

Looking for Warm or Hot spots

When the slab has been compromised you’ll notice that there are, what are refereed to as, “heat” or “hot” spots throughout your home. If you notice warm spots on your slab it could mean that you indeed have a leak. 

Sound of Running water

The sound of water dripping, rushing or settling is also going to be a major sign. If all of your appliances and fixtures are turned off, but you still hear the sound of running water in your home, it could mean that you have a leak in your slab. Often times you will not see the effects of the leak, so it’s important that you’re on guard and have family members paying close attention to any sounds like water dripping or running.

Leaks Behind Walls

If you hear water running, or notice that there is wetness on floor any place in your home, you most likely have an issue. 


Look for cracks in your slab or foundation. This sign could indicate that the water leak is weakening the concrete. 

Water Bill

If your water bill has gone up and you do not recall increased consumption or filling your swimming pool, it might mean that you have a leak under the slab.

If any of these signs are present, CALL US IMMEDIATELY at 855.840.7800 or click for immediate assistance. Flood Brothers Plumbing can mitigate any potential flood damage and fix the leak before the problem gets out of hand. The longer you delay the worse the scope and scale of the damage can be.

There are three different proven options for repairing a slab leak.

The most common methodology is to use specialized leak detection technology to localize the source of the leak and then jackhammer out a section of your slab where the leak is. Our plumbers will replace the compromised section of your water pipe with new pipe and then fill in the hole with concrete.

Another method is to completely re–route your water lines outside of the slab and run them overhead along the outside of the house. Our slab leak specialists cut the supply water line at the point of entry into the slab and route new lines elsewhere outside your home. This approach ensures that if you have any future issues with your aging water line, it won’t harm your slab.

Finally, using flexible PEX or polyethylene pipe (as opposed to rigid copper), Flood Brothers Plumbing can also re–route your water line inside your walls with minimal damage. Think of it as arthroscopic surgery where our slab leak specialists strategically make small holes in the walls (just like a surgeon would make small incisions when using an endoscope) so we can run the flexible PEX through your walls and wooden studs without tearing up your house.

Working with your insurance company to resolve Slab Leak issues in Los Angeles, the San Fernando Valley and Ventura County

Flood Brothers Plumbing has a great deal of experience working with insurance companies. Generally homeowner’s policies will not cover the cost of the plumbing repair itself, but you can expect it to cover the cost of the leak detection service, access and isolation of the water line where the leak is (jack hammering, excavation etc.), dry out from the water damage and restoration of your property (filling up and re-cementing) to the condition before the leak occurred. Insurance company responses will vary from incident to incident and claim to claim. It is always a good idea to talk to your representative or insurance agent before filing a claim to determine what your coverage really is.
