Lange installed a sign for my bed and breakfast about six months ago. The service was excellent, and I have been extremely pleased with the outcome. Many residents around town have commented to me about how nice the new sign looks. I am sure that I am now easier to find, and the sign has been helpful advertising for those driving by. I would certainly recommend Lange to other businesses.
