Wonderful customer service experience. Nathan the tech that they sent out did a phenomenal job. The lady in the office Laura doing the scheduling was super pleasant to work with. Great workmanship speedy service. Extremely thrilled. They got our house ready to sell and code compliant and took away the worries. I heartily recommend this family owned local business for your electrical needs. As long as you have them I will vouch for their service and they're great. They even fit us in in a very difficult tight schedule window and we are exceedingly pleasant about it Frank Drinkhouse Belleville, IL

This company helped me and my family when no one else would. Sent a tectniton, and a young lady out to my home. To restore power after a big storm. I will always recommend this top notch company to anyone that needs any electrical services done.
