The term “slab leak” is used to denote any leak that occurs in a plumbing system that runs underneath a slab foundation of a building. A slab foundation is a common type of building foundation comprised by concrate and reinforced by rebar. The slab may be as thin as four inches and as thick as twenty inches. However, for homes built in Southern California we typically see 4-6 inch slab foundations.

    Everyone from scheduling to service were great. Honest, to the point, and knowledgeable. They were able to fit me into their busy schedule withing hours...SAME DAY!!! I would recommend them in the Newport Mesa are for sure. FYI- they replaced the pilot assembly kit/thermocouple in my GE water heater. Not an easy task as it requires dis-assembly and taking the heater pan out.
