"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."
"Bought a new house and had a pre-purchase sewer camera inspection done. The plumber walked me through the footage and pointed out one section that would need attention in a few years. Honest assessment, no upsell pressure."
"Our older boiler was making banging noises and losing pressure. The technician diagnosed a failed expansion tank, replaced it, and the system has been silent ever since. Reasonable rate and quick turnaround."
