A dark neon sign costs you twice: once for the repair you have been putting off, and every single night in customers who drive past a storefront that looks closed. Here is how neon fails, what fixing it typically costs, and how to decide between repairing the neon you have and retrofitting it with LED that looks the same and outlasts it.
Neon is glass tube, noble gas, and high voltage, and each part fails in its own way. The good news: the symptom usually points straight at the cause.
| Symptom | Likely cause | Typical fix |
|---|---|---|
| Entire sign dark | Failed transformer or tripped GFCI | Transformer replacement or circuit repair |
| One section out, rest works | Broken or leaking tube | Tube re-blown and re-gassed |
| Flickering or buzzing | Aging transformer or loose GTO connections | Rewire and transformer service |
| Dim or discolored glow | Gas depletion in old tubes | Re-gassing or tube replacement |
| Dark after rain or cold snaps | Moisture in housings or failing insulation | Reseal, rewire, weatherproof |
This is the fork in the road, and the honest answer depends on the sign. Here is the comparison we walk owners through on site.
| Neon repair | LED retrofit | |
|---|---|---|
| Up front cost | Lower for single failures | Higher once, comparable to a second repair |
| The look | The genuine article | Modern LED neon is nearly indistinguishable |
| Energy use | High voltage, higher bills | Roughly 80 percent less power |
| Durability | Glass and weather do not mix | No tubes to break, sealed drivers |
| Lifespan | Years between services | Often a decade or more |
A technician inspects the sign on site first, tests the transformer output, checks every GTO connection, and looks for the moisture and cracking that cause repeat failures. That inspection tells us whether the fix is electrical, glass, or both, and it is the basis for the fixed written quote we give before any work starts. Tube work is scheduled once glass is bent to match your sign’s colors and shapes, since neon tubing is made to order, not pulled off a shelf. On a full restoration we also photograph and measure every section before removal, so the finished piece matches the original layout instead of an approximation of it.
Every sign is different, but typical projects land in familiar ranges. A service call with diagnosis is the starting point. Transformer replacements are usually a few hundred dollars installed. Re-blowing a broken tube runs by the section, and full restorations of large vintage signs are quoted after inspection. Cost climbs with the number of tube sections involved, ladder or lift access, and how custom the glass bends are. You get a fixed written number before any work begins, and if a retrofit makes better sense we will price both paths side by side. Larger restorations and full retrofits can be paid off over time too, with financing available and $0 down options so a dark sign does not have to wait on next quarter’s budget.
Illuminated signage across our service area gets the same attention a neon restoration would, whether that means chasing down a flickering channel letter or keeping a pylon sign bright enough to read from the highway. We have relit and rewired signs for businesses ranging from national chains like Caliber Collision to local storefronts, and the diagnosis process is the same every time: find the actual point of failure before quoting anything. If the sign in question is a fluorescent cabinet rather than neon, the Illinois fluorescent bulb ban changes the math on your next relamp.
