With each project, your reputation is both proven and put to the test. As a general contractor, delivering projects on time and within budget is what brings in new clients and brings back returning ones. Every detail matters, from the foundation to the final flourishes. But one crucial element that often gets left until the last minute is business signage.

A poorly planned commercial sign installation can cause unexpected delays, frustrated clients, and a pushed back project closeout. To keep your projects running smoothly, it’s essential to understand the nuances of sign installation. This guide covers the top seven things every general contractor in St. Louis needs to know about integrating business signage into their construction plans.

1. Signage Is the “Finishing Touch” of Installation

Think of signage as the icing on the cake of your project. It typically falls under Division 10 specialties and is one of the final components to be installed. But why wait until the end? Installing signs when the construction process is almost complete protects them from accidental damage caused by heavy machinery, painting, and other construction activities.

Scheduling the installation close to the project turnover date ensures the sign remains pristine for the grand opening and gives that welcoming first impression that will keep the client’s customers returning.

2. Allow Sufficient Lead Time for Custom-Built Signs

You can choose so many construction materials directly off a shelf, readily available when you need them. However, nearly every business sign is custom-built. From monument signs to illuminated channel letters, each piece is made to order.

This means lead times are longer than you might expect and vary drastically based on the materials, e.g., metal, acrylic, or digital components. To prevent that dreaded last-minute scramble, it’s important to coordinate with your commercial sign installation partner early in the project timeline, giving you enough notice to finalize designs and obtain necessary permits.

3. Artwork Requirements Matter: Focus on Vector Lines

For that sharp, professional quality that makes a sign pop, the fabrication process requires high-quality vector artwork. A low-resolution JPG or a logo pulled from a drawing just won’t cut it. Vector files (commonly ending in .AI, .EPS, .SVG) can be scaled to any size without losing quality or beginning to pixilate, ensuring clean lines and a crisp final product.

The business owner or their marketing team usually has these brand assets. Requesting these files in advance of when they are needed is a simple step that can keep your commercial sign installation project on schedule.

4. Illuminated Signs Need Proper Power Access

If your project includes an illuminated sign, electrical planning is essential. These signs require a connection to the building’s power, which must be run to the exact sign location during the rough-in phase.

Coordinating with your electrician to ensure power access is available behind the wall will prevent expensive change orders and delays down the line. Thus ensuring your project finishes right on time.

5. Remote Power Supplies Are Often an Option

For a cleaner commercial sign installation and easier maintenance, the drivers and power supplies for illuminated signs can often be placed remotely. Spaces like IDF closets or an electrical room are common choices.

This approach reduces clutter behind walls and simplifies future service. However, it requires meticulous upfront coordination with your electrical team to prevent voltage drop, ensuring the sign remains bright and functional.

6. Green Building Barriers and Envelope Requirements Can Be Maintained

Worried that a commercial sign installation might compromise your building’s envelope? A professional sign company knows how to work around modern construction standards.

Sign systems can be installed without affecting vapor or weather barriers. By coordinating with your envelope subcontractors, we ensure that all installations adhere to green-building best practices, maintaining the integrity of your structure.

7. Sign Permits Are a Separate Process—But We Take Care of Them!

A common misconception is that commercial sign installation permits are included under a general building permit. However, this is very rarely the case. Each municipality, especially within St. Louis County, has its own unique set of rules and regulations for signage. It can be easy to trip up while navigating this complex permitting terrain.

At Landmark Sign Company, we handle the permitting process from start to finish, ensuring your signage is fully compliant and free from bureaucratic delays.
