Our reputation is built on results. Here is what our customers have to say.
"Late-night leak under the kitchen sink, had someone out within 90 minutes. Stopped the leak, replaced the shutoff valve, and I could finally go back to sleep."
"Smelled gas in the basement late at night and called the emergency line. A plumber was dispatched within the hour, located the leak at a corroded fitting on the water heater gas line, and repaired it on the spot. They even came back the next day to re-verify with the gas detector. Truly appreciated the care taken."
"Been meaning to write this for a while. Our sewer line collapsed and we had three quotes — two wanted to dig up the whole yard, Magnet recommended trenchless. They finished in two days, no damage to the lawn, and the price came in thousands under the other guys. The Magnet team knows what they are doing and I will not hesitate to call them again."
