Excellent panel upgrade
Trinity did a full panel upgrade at our home and the work was flawless. They were on time, clean, and explained everything clearly. Highly recommend to anyone in the Medford area.

Fast and professional
Had a tricky wiring issue in an older Cambridge home. The team diagnosed it quickly and had everything fixed the same day. Very professional from start to finish.

Great commercial work
We hired Trinity for a full electrical build-out of our new office space. They stayed on schedule, communicated well, and the final result was exactly what we needed.

EV charger installation
Had a Level 2 EV charger installed in my garage. The electrician was knowledgeable, efficient, and left the workspace spotless. Will definitely use Trinity again.

Whole-home rewire
Trinity handled a complete rewire of our 1960s home. The project was large and complex but they managed it seamlessly. We feel so much safer knowing the electrical is up to code.
