Excellent work. Knowledgeable electricians and fair pricing.
Great service. They know their stuff. Great for commercial lighting needs
FSG has been the classic example of a company that under-promises and over-delivers. I can vouch for them. These guys are the real deal.
The guys at the counter were very friendly and knowledgeable. They also helped me select the perfect LED’s for my location. Thank You.
FSG is an amazing Company! They recently replaced both interior and exterior lights on our property at Arrowhead Ridge Apartments. The staff is very professional and always friendly. B.Quintana was always great with following up & making sure everything was on track. I would recommend this company for any of your electrical needs!
In FSG, we found a partner that will be here with us for the long haul. We know that if ever we need them, they are only a phone call away.
While the products and service provided by FSG and Bernie Erickson have always been good, the service they have provided to schools across Montana during the past seven months of the pandemic has been exceptional! Montana Cooperative Service with member districts across the state has recently awarded FSG our highest award, Montana’s ‘Best of the Best’ for 2020.
The sales people here were so helpful, knowledgeable, and attentive. I had visited 2 other lighting stores before this one. They were able to diagnose and resolve my lighting issue (a broken ceiling hanging lamp) and answer all my questions. I really appreciate their patience and the time they took to help me.
Best company to use for your electrical needs Jason is always helpful.
