Raul did an excellent job of locating and resolving our problem with a leaking water line. After the site of the leak was presumably found in our driveway by an underground pipe and cable company,, Raul jack-hammered the location only to find no leak. A repeat visit by a second leak locator resulted in different location outside of the driveway and the one that proved to be right.. Raul found the leak and completed the patch to end the leaking pipe. He was very dedicated to resolving out problem despite the frustrations. Raul was very dedicated and I was very happy with his work efforts.
