Frequently Asked Questions

Can channel letter signs be customized?

Yes, channel letter signs are highly customizable. You can choose from a variety of fonts, sizes, colors, and finishes to match your brand identity. Additionally, options like face-lit, halo-lit, or non-illuminated designs allow you to tailor the sign to your specific needs.

What electric is needed to install channel letter signs on the exterior of a building?

Most illuminated channel letter signs require a 120V power source to operate the LED lighting or other illumination types. This is typically provided by the building’s main electrical system. They will also require a dedicated circuit from your breaker panel to the sign location.

What are channel letter signs made of?

Channel letter signs are typically made from durable materials like aluminum for the letter structure and acrylic for the faces. These materials are weather-resistant, ensuring the sign lasts for years outdoors, withstanding various environmental conditions. The acrylic faces are covered in a translucent vinyl, making them appear a solid color during the day and the same brightly illuminated color at night.

Are town permits required for exterior illuminated signs?

Yes, permits are typically required for exterior illuminated signs to ensure they comply with local zoning, electrical, and safety regulations. The process varies by location, so it’s important to check with local authorities or hire a sign company like Williver that can handle the permit process for you.
