Sign Wave is the best ! They lettered my carpet cleaning van and I LOVE it, I would highly recommend them to anyone looking for a great looking sign and great service!
Chris Vigil Owner of CleanRite Carpet & Upholstery Cleaning
I was amazed, impressed by Sign Wave's suggested ideas on the signs. Jean, the owner, provided me with thoughtful, constructive feedback on my options including the advantages and disadvantages - not to mention benefit vs cost. I would recommend anyone who is searching for signs to opt to use Sign Wave.

Sign Wave did an amazing job of creating a frosted look for my shop window and Jean was able to deal with the intricate design of the sign with no problems. The turnaround was faster than I expected too. All round a great service.
