Exterior Signs

Seattle weather does not go easy on signage. Our exterior signage is built to hold up to rain, wind, and gray winters without losing its color or structure.​

This includes:

Interior Signs

A well planned interior sets the tone before a customer or tenant ever speaks with your staff. Our interior signage covers everything a modern office, retail space, or medical facility needs.

This includes:

Digital Signs

For businesses that update their message often, digital signage keeps you flexible without sacrificing a professional look.

This includes:

With as much time as vehicles spend sitting in Seattle traffic, a wrapped fleet is one of the most efficient ways to advertise. Our vehicle graphics turn cars, trucks, and vans into rolling brand impressions.

How We Support Your Project Beyond the Sign Itself

Building the sign is only part of the job. Our solutions cover everything around it, so your project stays on track.

  • Sign Design and Consultation — Our designers translate your brand and your space into a concept that actually works once it is built.

  • Sign Installation — Licensed installers handle everything from a simple wall mount to a complex electrical install.

  • Permit Design and Procurement — We prepare and submit the paperwork Seattle and King County require, so your project is not held up in city offices.

  • Sign Retrofit and LED Retrofit — We can modernize signage you already have instead of starting from scratch.

  • Sign Maintenance, Repair, and Cleaning — Ongoing care that keeps your signage looking the way it did on installation day.

  • Site and Building Surveys — A survey before design begins so placement, sizing, and mounting are right the first time.

  • Sign Removal — Safe removal and disposal when it is time for something new.

  • Project Management — A single point of accountability for your entire project, from the first sketch through the final walkthrough.

Why Seattle Businesses Choose Mustang Signs

We are recognized as one of the top sign companies in the Northwest. Part of how we got there is pairing our own experience with published guidance from groups like the International Sign Association, rather than relying on instinct alone.

Our team manages the technical requirements too. ADA compliant signage, for example, has to meet standards published by the U.S. Access Board, and we design to those specifications as a matter of course, not as an afterthought.

Frequently Asked Questions

What kind of signage can you provide for a Seattle business?

Nearly all of it. Exterior signs, interior and wayfinding signage, digital displays, vehicle wraps, and printed materials are all part of what we offer, along with the design and permitting work behind them.

Do you handle sign permits for Seattle and King County?

Yes. Permit requirements vary by jurisdiction, and our team prepares and submits the drawings and paperwork your project needs so you do not have to manage that process yourself.

How long does a typical sign project take?

Printed items like banners can often be ready in a few days. Larger installations, especially ones that need a permit, are a different story: plan on roughly four to eight weeks between your first conversation and a completed, permitted sign. We will narrow that down once we understand your project.

Can you manage signage across more than one Seattle location?

Yes. Our project management approach was built for exactly this kind of work, keeping design, materials, and installation consistent across multiple sites so your brand looks the same everywhere it appears.
