Testimonials

Last year I bought a Kohler generator from DeRock Electric. I’m so glad I did. After that huge snow storm we had I would have been out of electric for 3 days! Thanks!

I’ve been happy with the services provided by DeRock Electric. Doug and his crew did an awesome job fixing my parking lot lights!
