Carlos did an excellent job locating two separate under-slab leaks. On the first leak, our water bill was climbing with no visual indications. Carlos located a moderate leak under our master bathroom slab. After that leak was fixed, a second leak sprung up across the house under the slab between the garage and a guest bedroom. Carlos was able to cut out enough of the concrete slab to pinpoint that leak. With both leaks repaired, our house is again leak free.
