“Referred by my family”
“At a family recommendation, I called Mallick Plumbing to get a new ball valve, piping and pressure valves, all of which had minor leaks. A few days after the call, our technician, Luis, came out right on time and started work immediately. He was very professional and efficient at getting these fixes completed. He kept the area clean and answered a few questions about the install. I would definitely recommend Mallick Plumbing. Very reasonable price for professional quality work!”
