"Great service and both Brandon and his coworker were professional, prompt and courteous. I rated customer 4.5 only because for the generator install he had forgotten to tell me I would need gas lines run, which increased the price 450$."

"Klaus, owner of Resolute Electric, showed up initially to complete the estimate. Klaus was on time, professional and left us feeling we chose the right guy for the job. Klaus provided an estimate within 24 hours, we scheduled the date of the installation and Klaus arrived exactly when he said he would be there. He was very knowledgeable about what needed to be done, did not hesitate to get started and completed installing the flood light in exactly the area we wanted and removed power to the base board heating at the junction box. The flood light needed to be hard wired and Klaus was nothing less than stellar from the moment we met him to the time he left after completing everything we requested. Resolute's pricing is very fair and anyone that uses Resolute will 100% be satisfied with the price and work performed."
