"The guys from USA Plumbing did a great job repairing a hard-to-reach hot water leak in a pipe encased in the concrete foundation beneath my furnace unit. The lead worker Danny identified the source of the leak and with great effort he and his assistant, working in an impossibly cramped space, freed the pipe from the concrete and expertly repaired the copper piping. Days on, no more leaks were detected. I would highly recommend USA Plumbing for difficult pipe repair work of this nature."
