"Eric did all the electrical work for my new home construction, including wiring for a whole house generator, an RV pad, and an electric vehicle. His work was outstanding, with great attention to detail, such as labeling the electric panel, and making sure his work area was cleaned up after each job was completed. I would have no hesitation in hiring Eric for any future electrical work and, in fact, have hired him for several smaller projects since my house project was completed. I believe his prices are fair for the quality work that he provides."
