Channel letters are the dimensional, individually-fabricated illuminated letters mounted to a building face that most people picture when they think of a modern storefront. Each letter is a self-contained, three-dimensional aluminum can with an acrylic face and internal LED illumination. They're the workhorse of commercial exterior identification — used by national chains, independent restaurants, retailers, medical offices, and franchise locations across Cincinnati and the tri-state. If you have a leased building face, a clear sight line, and want a polished, permanent brand presence visible day and night, channel letters are almost always the right answer.
Materials & Construction
Returns and backs are formed from .040–.063 aluminum on our in-house brake and waterjet, then welded or riveted into a sealed can. Faces are 3/16″ acrylic — typically white #7328 with translucent vinyl overlays for color matching, or pre-pigmented colored acrylic for a richer night appearance. Trim caps in matching or contrasting colors finish the perimeter. Inside each letter we install UL-listed Principal LED modules driven by remote 12V or 24V power supplies, sized for even face brightness with no hot spots. Mounting hardware is non-corrosive — stainless studs through the substrate, sealed with silicone, with a remote disconnect required by NEC for service.
Common Use Cases
- Restaurant and quick-service storefronts
- Multi-tenant retail and shopping center facades
- Medical office buildings and dental practices
- Automotive dealerships (rooftop and façade)
- Franchise rollouts that must match a national brand standard
- Professional offices, banks, and financial services
Code & Permit Considerations
Channel letters are illuminated electrical signs, so virtually every jurisdiction in our service area requires both a sign permit and an electrical permit. Most Cincinnati-area municipalities also require sealed engineering drawings showing wind-load calculations and attachment detail. Landlord approval is typically required for leased spaces, and sign-code variances may be needed when the proposed copy area exceeds the allowable square footage for the building frontage. We handle all of this in-house — drawings, applications, fees, and inspector coordination.
Pricing Range
$3,000 – $8,000
Most single-line storefront sets land in this range. Pricing scales with letter height (typical 12″–24″), depth (5″ standard), illumination type (face-lit is most economical, halo-lit / reverse channel costs 20–40% more), raceway vs. flush mount, and the height/access of the install. Multi-line sets, oversized rooftop letters, and exotic finishes (brushed stainless, copper, dual-color illumination) move the project upward.
Lifespan & Maintenance
Properly fabricated channel letters last 15–20 years before the cans themselves need replacement. The LEDs and power supplies inside are the wear items — modern UL-listed LED systems carry 5–7 year manufacturer warranties and will typically deliver 10+ years of usable light before brightness degrades enough to warrant a retrofit. Annual visual inspection and cleaning of the faces is the only routine maintenance most sets need.
