Incredible!! These guys are top notch. We had another local company service our sign, and after 3 trips they still couldn't get one working, and left our other sign lighting multi-colored. Columbia Sign came out and fixed everything in one trip. Not only did they fix the one, they made the light match in the other, then they fixed several parking lot lights on top of that. They had every single part they needed, and were out of my customers way incredibly fast. The service tech explained everything that he needed to do, and knew prices off hand. These guys are professionals. They have my business.

If u want your sign not to work then these arEven the ones to use been 3 months trying to get my sign fixed and still to this day only half works have called and told I will be put on a list. I guess I never get to the top of ur list columbia would be a good place for a sign service company
