I’m extremely happy with how accommodating and professional the company has been. The owner has gone above what I’ve asked for and given this field their prices are VERY fair. More than anything the owner is pleasant and keeps his word. That’s Our Electrician!!!

Well... Mainline Electric gave me hope for the future of the new generation of Tradesmen. Jordan and his brother (The Owners) were absolutely spot on. First, they responded the same day of my request for a quote and showed up the same day as well. Jordan was very professional and attentive to my needs. They showed up on time to do the work and once again were respectful/professional/on time. They cleaned up/locked the basement door they were using/etc. I couldnt be happier for this younger company. They have the professionalism and knowledge that is needed more these days. They are without a doubt my new go-to for all electrical work. Thanks again guys for kicking ass/cleaning up/good pricing/etc.

Nice work done at a reasonable price, ran 100 amps from a 1950s ranch out to the detached garage, wouldn’t hesitate to use them again in for future projects.

Very professional and friendly I just needed a simple thermostat replaced upstairs, efficiency and Professionalism chatted and explained the process which is really nice because most of the other companies they just do the work and don’t explain it. I will be going back to them to get a quote on digital thermostats for downstairs after the holiday season but I highly recommend these young gentleman.

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.
