"Mike arrived on time and began work immediately. He removed old wiring and installed all new wiring and conduit and repaired a few down spouts at the same time. He installed all new lights along the walkway, removed an outlet that was of no use and re-wired the entire front of the house including wall flood lights. Mike had to dig up flower beds etc. to accomplish his work and when he left you would not know he was ever there. He cleaned up the walkways and removed all trash. He kept in touch with me regarding progress. I have used them several times for non electrical issues also. Their communications system is top shelf. They always call back, confirm appointments and follow up on their work. All of their techs are professional, courteous and respectful of your property. I feel their prices are fair. I would highly recommend them for all your needs."
