Every sign project begins with the same question, and every honest sign company gives the same first answer: it depends. That said, “it depends” is not a budget, so this guide lays out the typical 2026 ranges for the St. Louis market, the factors that move a quote up or down, and the line items that surprise business owners after the contract is signed. One point is worth making before the numbers. A sign is not an expense so much as an investment- in a FedEx Office survey, 76 percent of consumers said they had entered a store they had never visited before based on its signs. Few marketing purchases work harder for longer.
2026 Price Ranges at a Glance
| Sign type | Typical installed range |
|---|---|
| Illuminated channel letters | $2,000 to $20,000+, with most storefront sets landing between $4,000 and $8,000 |
| Cabinet (box) signs | $1,500 to $10,000, often 20 to 40 percent less than comparable channel letters |
| Non-illuminated dimensional letters | $1,000 to $4,000 |
| Monument signs | $5,000 to $50,000+, with most projects falling between $5,000 and $20,000 |
| Pylon and pole signs | $15,000 to $100,000+ depending on height and tenant panels |
| LED message centers | $5,000 to $20,000+ for the display alone, added to the structure cost |
| Vinyl and window graphics | Roughly $10 to $15 per square foot |
These figures reflect typical industry and regional pricing rather than a formal quote, since every sign Piros builds is custom designed and fabricated for its specific building, jurisdiction, and brand.
The Three Factors That Drive Cost Most
The first factor is size. Larger signs consume more aluminum, more acrylic, and more LED modules, and doubling a letter’s height can far more than double its material requirements. The second factor is materials, where choices like stainless steel, thicker gauges, or stone monument cladding convert a higher upfront cost into a longer service life. The third factor is illumination. A non-lit sign is the least expensive path, front-lit LED channel letters occupy the middle, and digital displays and message centers sit at the top, delivering the most capability at the highest price point.
The Line Items Buyers Forget
Four costs routinely go missing from the first draft of a sign budget. Permits typically run $100 to $500 and vary by jurisdiction, and in this region the jurisdiction question is genuinely complicated, since the City of St. Louis and the county’s many municipalities each run their own processes. Engineering comes second, because freestanding monument and pylon signs generally require stamped structural drawings that add roughly $500 to $2,500. Third is electrical, because an illuminated sign needs a dedicated circuit, and not every building has one waiting. Lastly, installation access matters: a sign mounted 90 feet up a high-rise or pylon structure requires cranes and specialized crews that a ground-level storefront does not, and professional installation is priced accordingly.
Why the Cheapest Quote Is Often the Most Expensive Sign
Underpriced bids usually subtract something you cannot see on the proposal- insurance, permit handling, or component quality. Cheap LED modules fade and fail within a few years, uninsured installers transfer their risk directly onto your business, and unpermitted work invites the fines and removal orders we covered in our guide to the cost of non-compliance. Piros Signs is licensed, insured, and operating a fully UL-listed manufacturing shop with more than 67 years in the trade, and our reviews reflect what that buys: signs that go up correctly and stay up.
