Amazing work very professional and affordable
These guys were great! Professional yet funny! My bill came in at half the estimate! Would highly recommend!!!!
We’ve referred derek & crew to several customers. And will continue to do so. Honest, straight forward, and great work.
We recently bought and moved into a new home in Manchester. The house was in need of significant electrical upgrades. They came right out, gave us a more than fair estimate. They kept with their estimate even with a few minor additions. Great crew! Professional, great communication, and top quality work!
I hired Simpson Electric to add a circuit to my electrical panel. Communication was great and he showed up right on time. While there he brought to my attention an issue in my panel that was not compliant with current electrical code and corrected it at a very reasonable cost. Fantastic work ethic, great pricing, trustworthy... I'll be using Simpson Electric for another job at my house later this summer. Highly recommend.
