Absolutely, we understand that it is not always simple to bring a piece in for us to look at, so depending on your location, we can come and investigate the fault and make any subsequent repairs on site.
Doing it this way will cost more than having the sign repaired at our factory and may require one trip to investigate and a second to fix the issue.
This will depend on how old the sign is and where it was made. If it was made in the UK and within a few years, then there should be no problems matching tube colours and sizes.
However, if the sign is particularly old, newer colours may be slightly different and if the sign was made in a different country, such as China, then we may not be able to match at all.
Treat your neon sign the way you would treat any other electrical appliance. If it is not fully working as expected, turn it off and stop using it until it has been checked and cleared by a qualified person. Not only is this safer for you, if you leave a neon sign on when it is not fully functional, you can cause further damage to it, increasing the cost to get it back to its original state.
