They arrived on time and did a clean, professional job connecting our instant water heater at the studio bathroom. The work was high quality, and the pricing was fair and honest. Highly recommend them for any electrical needs.

 Trustindex verifies that the original source of the review is Google. We had Rolwes Electric come out to do an electrical thermal study at our company, Show Me That Print, and it was definitely worth having done. Steve, their thermographer, was very knowledgeable and took the time to explain what he was looking for and what he found. During the study, he discovered a hot spot in one of our electrical panels that we didn’t know was there. As it turned out, that issue was the underlying cause of some nuisance trips we had been dealing with on our equipment. It was great to finally find the actual cause of the problem, and even better that we were able to catch a potential electrical issue before it became something more serious. We were very happy with Rolwes Electric and Steve’s work. I would definitely recommend them to any business that wants to check the condition of their electrical system and catch problems before they turn into bigger headaches.

 Trustindex verifies that the original source of the review is Google. Colton did an outstanding job with my electrical installation today. He was professional, knowledgeable, and took the time to make sure everything was installed correctly and safely. He clearly takes pride in his work and paid attention to the details instead of just rushing through the job. He also did a great job explaining what he was doing and answering my questions along the way. It’s refreshing to have someone show up who knows what they’re doing, does quality work, and genuinely takes care of the customer. I couldn’t be happier with the work Colton did today. I would absolutely recommend Rolwes Electric for  anyone needing electrical work. Five stars all the way!
