A proper maintenance routine involves cleaning, inspecting, and repairing signs to keep them in good condition and keep the sign clear and easy to read. Inspecting tells you whether there are loose components, cracked panels, peeling vinyl, or fading colors. Electrical signs require regular bulb replacement, wiring inspection, and testing to ensure they are always bright. Structural elements, such as mounting brackets or support poles, must also be checked for stability. Keeping up with these tasks will extend the life of your sign.
