Can Neon Signs Be Repaired?

Neon signs can often be repaired, depending on the extent and nature of the damage and the technician’s expertise. With the right skills and tools, technicians can address common issues like:

  • Broken tubing
  • Electrical failures
  • Fading colors

Signs may be deemed beyond repair if the damage is too extensive, such as severe tube breakage or irreparable electrical faults. When these things occur, it may be more cost-effective to simply replace the sign entirely.


Regular maintenance and timely repairs are important. If you opt for custom LED signs from us instead of traditional glass ones, you will find they are more durable and resistant to damage, so the need for repairs is less likely.

Can You Repair A Neon Light That Flickers? Troubleshooting Neon Signs

A flickering neon light can usually be repaired. Here is a simple process to try and identify the cause of the problem yourself:

  1. Check for loose connections or damaged wiring. 
  2. If you spot loose connections, tighten them and inspect wires for damage.

If you cannot easily identify the cause, you may have an issue with the transformer or the tubing itself. This will likely require professional repair or replacement.

DIY repairs are suitable for simple fixes like lost connections, but issues with more complex electrical components or the glass should probably be looked at by a professional. With their expertise and specialist tools, they can diagnose and repair more complex issues safely and effectively.

Repairing A Neon Sign That Flickers Or Shuts Off

Flickering and sudden shutoffs in neon signs can be caused by various issues. Common faults include:

  • Loose connections
  • Damaged wiring
  • Malfunctioning transformers

Your first step should be to inspect the connections and wiring, looking for loose or damaged parts and tightening or replacing as necessary. If you can’t solve the problem this way, inspect the transformer for damage or malfunctions.

If the flickering or shutting off is caused by a common issue, you may be able to resolve it with some simple intervention and basic tools. But we recommend leaving the more extensive electrical work to professionals unless you have some specialist skills yourself.

Again, the more complex issues are much less likely to occur if you choose a high-quality LED neon sign.

Can A Broken Neon Sign Glass Be Repaired?

Careful consideration is required for neon sign repairs involving broken glass, as the repairs are complex and there are safety concerns involved. Small cracks or chips may be repairable using specialized glass adhesives, but larger breaks or fractures will probably require that the entire tube is replaced.

Take safety precautions around broken glass, such as wearing protective gloves and goggles. This is important to prevent injury. You should also be aware that the high-voltage electrical components in your neon sign require expertise and caution to work on.


We urge you to consult a professional neon sign technician for any repairs involving broken glass. They have the necessary experience and equipment to assess and act on the damage.

How Much Can I Spend To Repair A Neon Sign?

The expenditure involved in neon sign repairs varies widely depending on factors, such as:

  • The extent of the damage.
  • The complexity of the repairs.
  • The technician’s expertise.

Relatively inexpensive to moderately-priced repairs include things like tube replacements or electrical work. Comprehensive restorations and customizations, however, are likely to incur higher expenses. Neon signs require specialist skills to craft and manufacture, which is why they are quite expensive.

Prioritize timely maintenance and address issues promptly to mitigate larger potential repairs that incur a higher expense. An initial consultation with a qualified neon sign technician should lead to an estimate for the repairs so that you can assess whether it is viable.

Requesting A Quote On Neon Sign Repair

When you request a quote for neon sign repairs, you will start by reaching out to a professional technician or neon sign company. You will need to provide details about the sign’s condition, including reporting any issues you have observed and the specific repairs needed. Be prepared to share photos or descriptions to help with the assessment, or bring the light into a shop to be examined.

The technician you contact will evaluate the scope of the repairs, considering factors like:

  • The extent of the damage
  • Materials required
  • The labor involved


On the basis of this assessment, they will give you a detailed quote that outlines estimated costs and a timeline for the repairs. We recommend inquiring about warranties offered and get clarity on any concerns or questions before you proceed.

Safety And Value Concerns In Commercial Neon Signs Repair

Safety should always be a priority in neon sign repair as you are dealing with hazards like high-voltage electronics and fragile glass tubing. Eventually, neon lights burn out, and you should weigh the expense of repairs against potential risks and long-term value.

Assess the extent of the damage and compare the options of repairs versus replacement. You may save a little in the short-term with a repair, but if an older product has recurring issues or safety concerns, those modest benefits may be nullified.

One alternative is to replace your glass neon sign with one of our custom LED signs, benefitting from their:

  • Superior durability
  • Energy efficiency
  • Customizable designs

We supply a wide range of colors and bespoke design options, and you can order custom LED neon signs online from us, ensuring a safe and reliable modern alternative to traditional neon.

Is Repairing A Neon Sign By Yourself Dangerous?

There can be dangers associated with repairing a neon sign by yourself, as there is fragile glass tubing and high-voltage components. If you mishandle these elements, you could cut yourself with broken glass or get an electric shock. What’s more, improper repairs could mean your sign becomes a fire hazard or is damaged even further.

If you are attempting a DIY neon sign repair, pay heed to the following:

  • Disconnect the light from any power source.
  • Wear protective gloves and goggles.
  • Work in a well-ventilated area.


Only attempt DIY repairs if you have the necessary skills and knowledge. If you are in doubt about the work, consult a qualified technician to ensure the repairs are safe and effective.

DIY Tips On How To Repair Neon Light Signs

If you have a simple DIY neon sign repair to carry out, like replacing transformers or electrodes, begin by disconnecting the sign from power sources and ensuring you work in a well-ventilated area. Replace the faulty component following the manufacturer instructions and safety precautions.

If you have more complex repairs, like re-gassing tubes or repairing electrical faults, you will need the necessary tools and technical expertise. Diagnose the issue accurately and proceed with caution, consulting reliable repair guides or communicating with experienced technicians if needed.

Safety should always be paramount, and repairs should be conducted in compliance with electrical safety regulations. This will protect against accidents or further damage to the sign.

A Step-By-Step Guide To Repairing Neon Signs Wires

It takes precision and safety precautions to repair neon sign electrode wires successfully. Here’s a simple step-by-step:

  1. Gather tools: You will need insulated pliers, wire cutters, a soldering iron, heat shrink tubing, and protective gloves.
  2. Safety first: Disconnect the neon sign from the power. Wear protective gloves and work in a well-ventilated area.
  3. Inspect and identify: Look for damage or disconnection on the electrode wires.
  4. Cut and strip the wires: Use wire cutters to remove damaged sections and strip the insulation from the ends.
  5. Solder: Twist the wire ends together then solder them securely.
  6. Heat shrink tubing: Slide some heat shrink tubing over the soldered joint and apply heat to secure it.
  7. Reassemble: Test your new connections, then reassemble the sign.

Follow safety best practices at all times and consult a professional if you are uncertain about anything.

Advanced Tools For Complex Neon Light Repairs

Advanced neon sign repairs can only be carried out with specialized tools. Here are some you might need:

  • Tube benders: These are for shaping glass tubes to the desired form without breaking them.
  • Gas pressure gauges: These are to monitor and control the pressure of the inert gasses when re-gassing.
  • Electrode savers: Used for protecting electrodes during repairs.
  • High-voltage testers: Essential for checking electrical components for faults.
  • Bombarding transformer: A tool for cleaning and prepping glass tubes before sealing.


These tools are essential for achieving professional results with many more complex neon light repairs.

When Neon Signs Cannot Be Repaired

If the damage is too extensive, it may not be possible to repair a neon sign. This could be due to:

  • Severely broken tubing
  • Irreparable electrical faults
  • Significant corrosion

Glass neon lights last around 8 years, while LED neon signs can last for 15+ years under the right conditions. If your sign flickers constantly, fails to light up after multiple repairs, or has numerous broken components, it might be time to dispose of it and get a replacement.


Responsible disposal is important, as the devices can contain hazardous materials like mercury. Contact local waste management services for guidance on recycling your neon sign. Alternatively, contact a professional neon sign repair shop that offers disposal services to ensure environmentally safe handling of your old neon sign.
