"Dustin is a reliable, easy-to-work-with, knowledgeable professional and I would recommend him to anyone! He quoted us a very fair price for a generator hookup and interlock kit installation, and was pleasantly surprised at how competitive his pricing is. He showed up exactly on time, maintained excellent communication throughout the process and 100% stands behind his work. If I need more electrical work done I will certainly be contacting Dustin again!"
