Repairing a neon sign with a broken glass tube typically costs $150-$600, with an average bill near $325; large, custom, or hard-to-match signs can exceed $1,000. The main price drivers are tube length and color, whether the transformer still works, labor time, and access to the sign.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Broken tube repair | $150 | $325 | $600 | One accessible tube; testing included |
| Custom glass tube fabrication | $100 | $250 | $500 | Per replacement tube, before labor |
| Transformer replacement | $150 | $300 | $600 | Part and installation vary by capacity |
| On-site service | $100 | $225 | $450 | Travel, access, and minimum charges affect price |
Estimates are broad U.S. ranges for conventional glass neon; location, sign design, and shop minimums can change the quote.
What a broken neon tube repair usually costs
A shop repair for one short, standard tube commonly runs $150-$350. A longer or curved section, a rare color, or a tube that must be custom-bent often brings the total to $350-$600. Multiple broken sections can push the bill above $1,000, particularly when the sign must be removed and transported.
For one accessible tube, $200-$450 is a practical planning range. It generally covers diagnosis, a replacement glass tube, reconnection, and a basic operating test. Rates assume ordinary indoor access and no major electrical or structural damage.
Replacement glass alone is often priced around $100-$300 per tube, while a complete installed repair is higher because shaping, filling, wiring, and testing require specialist work. Some shops charge a minimum service fee even when the actual repair is small.
Where glass, labor, and testing appear in the quote
Ask whether the estimate includes removing the sign, matching the tube color, and checking the transformer. A quote that lists only replacement glass may not include the work needed to make the sign operate safely.
| Quote component | Typical price | What it covers | Common cost trigger |
|---|---|---|---|
| Custom glass tube | $100-$300 each | Bending and processing one replacement | Unusual lettering or color |
| Technician labor | $75-$150 per hour | Diagnosis, fitting, wiring, and testing | Several tubes or fragile construction |
| Transformer or wiring | $150-$600 | Replacement parts and installation | Failed or mismatched power supply |
| Removal and return | $50-$250 | Handling and transport | Large, elevated, or delicate sign |
| On-site access | $100-$450 | Service call, setup, and site work | Lift, ladder, or difficult mounting |
Labor is often the biggest variable after custom glass fabrication. A two-hour repair at $100 per hour adds $200 before parts, while a shop’s minimum charge may replace an hourly calculation.
How tube length and transformer voltage change the quote
Tube dimensions and sign construction affect both fabrication time and compatible electrical parts. A simple 12-24-inch straight tube is generally less costly to reproduce than a long section with tight bends, multiple letter shapes, or a color that is difficult to match.
Beyond roughly 3 feet of replacement glass, fabrication and handling commonly add $75-$250. A sign with several linked tubes may also need more diagnosis than a single isolated break. If the transformer cannot support the replacement tube’s electrical requirements, a compatible unit may add $150-$600 installed.
Signs mounted more than 10 feet above ground, fixed behind a window, or attached to a fragile backing may require extra crew time or lift equipment. Those conditions can add $100-$500, depending on the equipment and site access.
How long does a neon tube repair take?
Diagnosis and removal can take 30 minutes to 2 hours for a small, accessible sign. Custom glass fabrication may take several days to two weeks because the replacement needs to match the original shape and electrical characteristics. The repair itself may take another 1-3 hours once the tube is ready.
Same-day completion is not guaranteed when a glass tube must be custom-made. A shop may charge $75-$200 for pickup or inspection, and urgent scheduling can add 20%-50% to labor or service charges. Confirm whether a diagnostic fee is credited toward the final repair.
When replacement makes more sense than repairing one tube
Repair is usually economical when one tube is broken and the rest of the sign, wiring, and transformer remain sound. If several tubes are failing, the sign has extensive corrosion, or replacement parts are unavailable, rebuilding or replacing the sign may provide better value.
Compare a repair quote with a full replacement quote once repairs approach half the price of a comparable new sign. A basic small custom neon sign may cost $500-$1,500 new, while a large or detailed sign can cost $2,000-$10,000 or more. LED-look alternatives may cost less to operate and can be cheaper to replace, but they do not reproduce the exact appearance of glass neon.
Three broken-tube quotes for different sign sizes
The examples below show how labor and access affect realistic totals. They assume conventional glass neon and no structural repairs; local rates and design complexity can shift each estimate.
| Scenario | Work and labor | Estimated total |
|---|---|---|
| Small window sign | One 18-inch tube at $150; 1.5 hours at $90 | $285-$375 |
| Medium storefront lettering | Two custom tubes at $400; 3 hours at $110; bench testing | $750-$1,050 |
| Elevated exterior sign | One long tube at $300; 3 hours at $125; lift and site charge | $850-$1,300 |
Example totals allow for modest shop fees or additional handling; permits or extensive electrical work are not included.
Why urban labor and difficult access raise repair prices
Neon specialists are less common than general electricians, so travel and shop minimums can matter as much as the repair itself. In major metro areas, quotes may run 15%-30% above typical suburban pricing. Rural customers may see 10%-25% more when a specialist must travel a long distance or collect the sign.
Get separate prices for bench repair and on-site service before approving work. A sign that can be safely removed and brought to a shop may avoid lift rental and elevated-work charges. Conversely, transport can cost more for a large, fragile sign, so ask the shop to price both options.
Which repair choices keep a neon tube bill down?
Send clear photos of the break, sign dimensions, and transformer label before requesting estimates. That helps shops identify whether the issue appears limited to glass or may involve power components. Request an itemized quote with parts, labor, service fees, testing, and warranty listed separately.
Keeping the repair to the damaged tube and reusing sound components can prevent unnecessary replacement charges. Avoid powering a sign with exposed wiring or a broken tube; professional diagnosis is safer than a do-it-yourself repair. Compare two or three quotes using the same scope, and ask whether a repair warranty covers the replacement tube and labor.
