At first I was a bit worried, but after speaking with Justin he walked me through the process, sent a specialist to my office, measured asked me a few questions then with in days sent me a formal proposal.
After a few weeks the sign was ready. They arrived promptly, removed my old sign and within an hour or two had installed the new one which had completely exceeded my expectations.
I can't than Justin enough for walking me through the process from start to finish. I am thrilled with the new sign and extremely grateful that I found California Sign Company and Justin. We will definitely recommend them to others and hope to use them as we expand into other markets.
