Astrid van BredaTrustindex verifies that the original source of the review is Google. The team here is wonderful. I had my electrical panel moved and all my outlets/switches swapped out. Arron came to quote, give the timelines & answer any questions I had. Nick & Thomas came for the work, they were wonderful and quick. Appreciate the team and will definitely recommend for other customers. Emily MacDonaldTrustindex verifies that the original source of the review is Google. Arron and his crew were wonderful to work with. It started with a professional consultation, where Arron ask what our needs were for the bathroom renovation. He offered suggestions and talked through all of my questions. He really took the time to make sure our needs were being met and had great style recommendations and really helped to elevate our remodel. The crew that completed the work were kind, hardworking, and easy to have in our home. They cleaned up after themselves and left the job site looking better than it had when they got there. I would 100% recommendations them to anyone looking for an electrician. They are dependable and fast workers. Worth every penny to know you are having a job done right the first time around. Gary NiggTrustindex verifies that the original source of the review is Google. Just moved into a new house in Littleton wired by Arron and team. My inspector was highly impressed with the organization of the electric panel and the electrician's attention to detail. After closing there were a few items left on the punch list. Arron was responsive, extremely personable, and cooperative. One of his team members Paul went out of his way to come a couple of days earlier than expected. Punchlist is done and I am very happy with how this went. Thanks Arron and Paul! ROSSTrustindex verifies that the original source of the review is Google.

GraceTrustindex verifies that the original source of the review is Google. Arron and team took what seemed like a nearly impossible problem and made it look easy to fix! We had a gas oven and wanted an electric (the plugs in the back of the oven were not compatible) so the entire downstairs needed to be rewired. Arron and his team were so responsive, helpful, professional, and fixed our problem with ease. We really enjoyed working with them and will be using them in the future!! Thank you! George LloydTrustindex verifies that the original source of the review is Google. We have a complicated old house with a history of sub-standard electricians. Every switch in the house needed some level of attention. R&A came in and seriously made it right. Listened carefully to my long list of fixes and went to work in a focused efficient fashion. With some larger stuff that included busting walls and moving switches, these guys were quick on their toes, worked fast through the long list all about the house and cleaned up as though they were never there. Polite, efficient, capable. Great work! We have found our electricians going forward. James PattersonTrustindex verifies that the original source of the review is Google. Immediately responsive when we had a problem and quickly got a great crew out to us who quickly fixed the issue we had, clearly explained what the problem was and were all around fantastic.
