Signs for St. Tammany Parish

Signs for the Northshore

You know a sign is doing its job when it feels like it has always belonged there. OPA Signs & Graphics designs, builds and installs monument signs, building signs and sign systems for businesses and communities across the Northshore.

We build in New Orleans and install across the lake, from Slidell to Madisonville.

Why Northshore clients choose OPA

Not every property needs the same impression

A historic downtown, a medical facility and a new commercial development all need to be recognized and understood. They shouldn’t look alike. A community entrance may call for a traditional look. A medical office may need something clean and architectural.

We start by understanding the place, then design the sign that fits it.

How a Northshore sign project works

Planned for the climate

Heat, humidity and heavy rain are part of life here, so structure, footings, materials and finishes are settled before we build. Our process, step by step.

A community entrance, a clinic and a new development each need to say something different. We begin by asking what people should understand the moment they arrive.
Traditional, or clean and architectural: the look follows the place. We study the property and its surroundings before we draw anything.
Drawings come to you for approval first. Covington, Mandeville, Slidell and other cities issue their own sign permits, and we work with you to find the right path for your address.
Our fabrication team pairs old-school craftsmanship with CNC routing and metal fabrication. That is how details like simulated wood grain hold up outdoors.
Our crews cross the lake to install what we build, and each project carries a 12-month warranty.
