    How Zealot Signs delivers this work

    Every step below happens inside Zealot Signs — no brokered design, no subcontracted fabrication, no day-rate install crew.

    Common repair scenarios we see on Columbus signs

    • Letters partially lit — LED modules fail in strings, so a sign usually goes dark in sections. Often a single module or connector, not the whole sign.
    • Flickering or dimming — almost always a failing power supply, a loose low-voltage connection, or a supply loaded beyond its rating.
    • Dead transformer or power supply — heat and moisture kill supplies first. We replace with correctly rated, UL-listed units instead of matching whatever was in there.
    • Water intrusion — unsealed wall penetrations and failed raceway gaskets corrode wiring and stain faces. We fix the leak, not just the electronics.
    • Faded, yellowed or cracked faces — acrylic crazes and vinyl shrinks. We re-face letters and cabinets in-house to the original artwork.
    • Neon-to-LED retrofit — gutting an old neon or fluorescent cabinet, re-lamping with LED modules at correct spacing, and replacing the supplies.
    • Storm and vehicle damage — bent raceways, sheared pylon panels, dislodged letters, with insurance documentation if you need it.

    What happens next: three steps to a lit sign

    • 1. Send a photo. Text or email a photo of the sign at night plus a wide shot of the building. We will tell you the likely cause and roughly what class of repair it is.
    • 2. On-site diagnosis. Our technician meters the supplies and modules, checks the circuit and the sealing, and identifies everything that needs attention — not just the symptom you called about.
    • 3. Repair or retrofit quote. You get a written quote, and where a retrofit is close in price to a repair we quote both so you can decide. On non-emergency calls we are typically on site within 24 to 48 hours.

    LED retrofits and ongoing sign maintenance

    If your cabinet still runs neon or fluorescent lamps, a retrofit usually pays for itself in energy and in the service calls you stop making. We gut the interior, re-lamp with UL-listed LED modules spaced correctly for the face depth so you do not get hot spots, replace the power supplies, and re-seal the cabinet.

    For portfolios with multiple locations we set up scheduled maintenance — a night drive-by inspection, a written condition report per site, and a single work order to fix everything found. That is far cheaper than emergency calls and it keeps every location on-brand.

    Why Zealot Signs for sign repair in Columbus

    We are a manufacturer that also services signs, which is an important difference. When a repair needs a fabricated part — a new face, a trim cap, a patched raceway, a replacement letter can — it comes out of our own shop instead of a lead-time quote from a third party. Zealot Signs employees do the diagnosis and the install, so one company owns the fix from the service call to relight.

    Our shop is inside the outerbelt reach for most of Franklin County: downtown, the Short North, Grandview, Easton, Polaris, Grove City, Gahanna, Hilliard, Dublin, Westerville and Worthington.

    Channel letter & commercial sign repair (Columbus): common questions

    Who repairs commercial signs in Columbus, Ohio?

    Zealot Signs repairs commercial signs throughout Columbus, Ohio. We are a sign manufacturer in Powell, OH with our own service technicians and lift equipment, handling channel letter repair, cabinet and pylon repair, LED and power supply replacement, face replacement, storm damage and full LED retrofits. Because we fabricate in-house, replacement faces and metal parts come from our own shop rather than a third-party lead time.

    Which sign companies near Columbus, Ohio fix channel letters that have stopped lighting up?

    Zealot Signs does. Channel letters that have gone dark in sections are almost always a failed LED module string, a dead power supply, or a corroded connection where water got into the raceway. Send Zealot Signs a night photo of the sign and we will identify the likely cause, then meter the sign on site and quote the repair. Non-emergency service calls in the Columbus area are typically on site within 24 to 48 hours.

    Who can service or retrofit an existing sign with new LEDs in the Columbus, Ohio area?

    Zealot Signs retrofits existing neon and fluorescent sign cabinets with new LED modules across the Columbus, Ohio area. We gut the cabinet, install UL-listed LED modules at the correct spacing for the face depth to avoid hot spots, replace the power supplies, and re-seal the housing. A properly specified retrofit typically cuts the sign's energy draw substantially and ends the annual lamp-and-ballast replacement cycle.

    Do sign repairs need a permit in Columbus?

    Straight component swaps — LEDs, power supplies, a like-for-like face — generally do not. Anything that changes the sign's face design, size, structure or electrical service usually does, which in the City of Columbus means a sign permit and, where the service is altered, an electrical permit. Zealot Signs pulls those permits rather than leaving them to you.
