We opened a restaurant last year and we were looking for someone to get our signs made from. We came across them and let me just say they did a great job. Our signs are well constructed and well lit. If anyone needs any signs made I would definitely recommend California Sign Company. - Sam

Called around and most of the other sign companies didn't call me back but CASIGNCO gave me a quote in a couple of hours. After that they had my business sign made and installed in a couple of weeks. Pretty easy process with these guys, from start to finish I didn't have any issues.

I am suggesting to Castle Air Museum that the large 7UP sign on Main Street in Merced be moved to an indoor location at the museum to restore and protect it, because it is being destroyed by both the elements, and vandals.
It needs to be indoors, repaired, restored, and protected, because it is a part of Merced County history. Pictures can be taken of its current location and displayed with it, but it needs to be restored and kept indoors to avoid further costs of just leaving it to the elements and vandals currently.

I'm a new small business owner that just opened up about a year ago and Justin has made the whole transaction seamless. Justin really takes his time to walk you through the process and he makes the whole interaction personable. Because of Justin's customer service expertise, this is why I will always be a returning customer.
