Had these guys install a sub-panel, fireplace outlet & generator lockout kit. Scheduled quickly, arrived on time and completed the job in a day. Left no trace of being here after cleaning up. Highly recommend them.

James and Jordan are professional, responsive, and their pricing is very fair. They were able to quickly come out and troubleshoot/repair my electric baseboard heaters. They thoroughly explained the work done and were happy to answer my questions. I would recommend Mainline to anyone!

A few months ago, Mainline Electric did an excellent job upgrading our electrical panel and we couldn’t have been happier with the experience. Their communication was professional from start to finish: clear estimates, quick responses, and they always kept us updated on timing. They showed up exactly when they said they would, completed the job, walked us through everything, and left the work area cleaner than it was before they started. That already puts them ahead of most contractors we’ve worked with. What really stood out was their reliability. We had an unexpected and unrelated electrical issue on 12/24, and even on Christmas Eve they answered the phone and got someone right out to fix the issue. That kind of punctuality and commitment to customers is rare in our experiences. Their work was clean, efficient, and clearly done with real expertise. I’d absolutely hire Mainline Electric again and highly recommend them to anyone needing electrical work.

James creatively designed solutions for me that has made my home a more convenient place to enjoy outdoor activities! He also installed an interlock plate in fuse box and outdoor plug so I now can connect my generator when power is out! James is very friendly and kind.
