Customer Reviews

Nick Drenth

I have had Nystrom help on various residential projects including rewiring an entire house. Their pricing is always fair. They explain alternatives and other options to keep things in budget and make sure the expected style matches what you are looking for. Their employees are understanding and professional. I have always had a great experience with Nystrom.

Our basement and main entry were flooded. As soon as we got the water out Ryan came out and looked at what needed to be done, gave us a fair bid and got started replacing our breaker box and got power back to our house in 2 days! Eric worked for 16 hours to replace everything! Great company and great service!

Ryan and the Nystrom team have taken great care of several projects in our turn of the century home. Ryan is helpful, prompt and makes sure that we have what we need for a plan before sending out his team. Electricians Jimmy and David both made sure they had a full understanding of our projects, including a full kitchen remodel, roughing in new rooms and upgrading our garage service to support electric vehicle chargers. They asked questions to make sure the installs were done correctly and were friendly and courteous during their time in our home. We couldn't be happier with our service from Nystrom and will be repeat customers.

Nystrom Electric provided timely and professional services to our home. We were able to get an appointment setup with the electrician for the very next day. The electrician showed up promptly at the time we agreed upon and walked me through what needed to be done. My issue was fixed and we will not hesitate to call Nystrom Electric again in the future for any additional needs!

We love Nystrom. They’re very timely in getting back to you and getting to your project. Very personable company, they even send Christmas cards. Our tech, David, was extremely kind and good at what he does. He always made sure to ask our preference in how we wanted lights hung, where we wanted outlets, etc. and he cleaned up well after himself. They will definitely be the company we call for future electric needs.
