Exterior Wall Signs: turn your building into a 24/7 brand ambassador.
Exterior Signage
Your building is a 24/7 brand ambassador. Exterior signage establishes first impressions and drives recognition before a customer even walks through the door.
- Wall Signs: Durable, highly visible, and customized to your façade—materials and illumination can be tailored to your long-term goals.
- Monument Signs: Low-profile, permanent structures that communicate credibility and help visitors locate entries even in height-restricted zones.
- Pylon Signs: Tall identifiers that provide long-range visibility along highways or shopping centers.

Monument signage delivers a confident, permanent first impression.
Wayfinding & ADA Signage
Once visitors arrive, interior signage takes over—guiding them confidently and safely.
- Wayfinding Systems: Directional, informational, and regulatory signs that move people seamlessly through your space.
- ADA / Code Compliance: Tactile and Braille lettering, contrast, and correct placement ensure accessibility for all.
- Brand Consistency: Cohesive finishes and typography unify your environment from the lobby to the back office.

ADA signage: clarity, contrast, and correct placement keep people safe and informed.
Wayfinding systems guide visitors from curb to counter without friction.

Best Practices for Effective Custom Sign Design
Designing effective custom signage is both an art and a science, blending brand strategy with real-world functionality. Whether you’re refreshing your existing signage or starting from scratch, keep the following best practices in mind to maximize impact and durability:
- Prioritize Readability: Choose clear, legible fonts and high-contrast color combinations.
- Align With Your Brand: Carry your logo, color palette, and core messaging through every element.
- Right-Size for Location: Scale graphics and type to the viewing distance and environment.
- Material Matters: Select materials that withstand your operating environment.
- Lighting for Visibility: Illuminate critical signs, especially exterior branding and entrances.
- Compliance and Accessibility: Incorporate ADA guidelines, Braille, and tactile graphics where required.
Remember: great signage isn’t just attractive—it’s engineered for performance, compliance, and longevity. Collaborate with a signage partner who understands both the creative and technical details for truly impactful results.
Selecting the Right Sign for Your Business
Choosing the right sign for your business is both an art and a science. It’s about reflecting your brand’s identity, making a strong first impression, and ensuring your message stands out—whether you’re nestled on a quiet street or anchored alongside national giants like Starbucks or Target.
- Location Matters: Consider your environment and visibility needs.
- Audience & Function: Think about who you’re reaching—directional vs. identity signage.
- Brand Voice: Match tone, materials, and style to your brand personality.
- Durability & Compliance: Choose materials suited to your climate and regulations.
- Budget & Expansion: Plan for scalability and long-term value.
By considering these factors, you’ll land on signage that not only captures attention but truly supports your business goals.
Storefront Sign Design Tips
A storefront sign is often your handshake with the world—a chance to shape perceptions before a customer steps inside. Here’s how to get it right:
- Prioritize Readability: Use large, bold text and strong contrast for visibility.
- Make It On-Brand: Keep colors, logo, and tone consistent with your identity.
- Use Quality Materials: Opt for weather-resistant materials like acrylic or aluminum.
- Consider Illumination: Add backlighting or halo lighting for visibility at night.
- Keep It Concise: Focus on your business name and purpose.
- Location Matters: Install where sightlines are clear and unobstructed.
Thoughtful storefront sign design isn’t just decoration—it’s an invitation, a promise, and a powerful statement rolled into one.
