What People Are Saying

“Clay is doing our outdoor and Indoor signage for my business, Woofie’s. He has been very responsive and his work is great. His customer service is great! For example, we found out that we were going to be interviewed by Fox News in 2 days and we had wanted to do the interview in front of our logo on the wall inside our office. Clay pulled together materials he had in his office, made the logo and came over and put it on the wall that day! It looks amazing. That is incredible customer service!!”
Tanya Lee, Woofie’s

“We are an Arlington-based cybersecurity company called ThreatConnect. We had a very nice experience with Clay when we moved into our new offices. Our requests were unique – from design to installation – and he adapted to them all. He was on-time, polite and really easy to work with. I would definitely recommend him.”
Christine Schaefer, ThreatConnect

“We used Clay to install a couple of really large and important acrylic logo signs at our work. We needed this particular job done at the last minute and he was quick to get our signs created and installed just the way we wanted them. I would absolutely use Clay again for our next work.”
Mary Lynn Reed, Next Century Corporation

“Wonderful experience from start to finish each time we have used SIGNS by Clay Downing! Clay is always prompt, personable and competitively priced. He installed our new window vinyls and lettering perfectly on our front display windows, taking time to thoroughly clean the windows first. We could not be happier with the results and look forward to working with him in the future.”
Sherri Bartlett, Wild Birds Unlimited

“​I run a small business in Falls Church City and needed to reface the sign on the front of the building. I checked with a few businesses and Clay was the most responsive. His price was reasonable and he was willing to help us with the permitting process. We ended up handing the permits but he provided some great advice. Once we got the thumbs up from the City, Clay had the sign up in a matter of days. He was unbelievably fast. On top of that, he’s a really nice guy. Before we had him under contract, he came by the shop to check things out and inspect the sign. We ended up chatting for a bit and I know after meeting him that his was the company we’d go with. We have no regrets and are completely satisfied with the service and the end of product. We highly recommend Clay for all of your signage needs.”

This is a nice example of laser-cut acrylic. The text is acrylic with a brushed aluminum laminate and the company logo is painted to match the customer’s PMS color.
