On The Grid is our go to contractor for all of our electrical needs. They’ve installed bathroom vent fans, outdoor outlet and just completed our kitchen renovation project. They are great at communicating, neat, clean and fairly priced. Highly recommend! Looking forward to having you back to change out our light fixtures and ceiling fans!
Mark and Doug were referred to us from a friend of mine and they were great! They Showed up exactly when they said they would, fairly priced, their work was done in the amount of time they said it would and the finished work is perfect! My husband and I are very particular about the contractors we hire and we would use On The Grid Electric again for any electrical needs!
Fantastic from start to finish! Transparent quoting and excellent execution. Will be calling back with any future electrical projects!
Excellent work, efficient, clean and friendly folks. Added several ceiling fans for us.
Exceptional job at a fair price. Doug, the owner, was in touch quickly. He sent his tech, Mark. Mark did a great job replacing 6 indoor and outdoor light fixtures and replaced an electrical outlet. Mark looked at some low voltage lighting I need help with on my deck, I will be working with him to update that soon. I recommend OntheGrid Electrical wholeheartedly. Having been through a difficult contractor situation recently for kitchen renovation, These guys restored my faith in contractors.
