Green Goo

You may or may not be familiar with this phenomenon, however if your home was built or rewired between 1965 and 1971 then there is a likelihood that this will or is already affecting you.

So what am I talking about? 

Those who are suffering from the effects of Green Goo in your property will notice the dark green substance seeping out of switches and sockets, it looks somewhat like Fairy Liquid and is tacky to touch, in some cases it is not so obvious and will remain unnoticed until some electrical work is carried out, in the most severe cases you will find it dribbling down the wall beneath your electrical outlets.


Why does it occur?

The bottom line is it is a fault of the manufacturing practice that was employed in the making of early PVC cable. Without getting too technical and discussing the makeup of PVC (polyvinyl chloride) what you need to understand is that PVC requires a plasticizer to be added in order to make it pliable to use in cables, the early plasticizers reacted with the copper in the cable when it reached a given temperature.

The concerns about this phenomenon range from the problems it can cause to the safety of the electrical installation to how it can affect your health.

If we look at the electrical installation first, then it is fair to say that a lot depends on the loading and usage. The warmer the conductors (cables) get the more the plasticiser leaches, this can result in the cable becoming brittle and eventually breaking down.

The goo substance itself can also cause issues with the functionality of accessories.  As for the health concerns contact with the Green Substance can cause ill effects such asdermatitis and or rashes. Therefore precautions should be taken to prevent skin contact.


What to do...

Unfortunately if an installation is seriously affected then the only real solution is to have the installation completely rewired. Simply replacing outlets/accessories will only serve as a temporary aesthetic solution, as the underlying problem still exists.


If you have concerns about your property then a simple insulation resistance test can be carried out by a qualified electrician, this will tell you to what extent your cable has or has not deteriorated.

My external security lights had failed and because they were over 20 years old, several electricians felt unable to help me. I then asked Karen from Bright Sparks to get involved. She promptly surveyed the problem, gave me a competitive quote and as soon as I accepted it, gave me a firm date for the work to be undertaken. Her electricians arrived on the due date, were very friendly and tidy and worked in difficult places without problem. I definitely intend to use Bright Sparks again.

We found the service to be friendly and pro-active. We had an appointment quickly and the engineer was able to find the issue, which was not straightforward, within an hour and rewire the effected ceiling lamp and resolve the issue completely within 2 hours. Very methodical and accurate working - most appreciated!

We have been very impressed by Bright Spark Electrical Services. Karen Smith visited us to discuss our requirements and gave advice which cut our costs. The work was carried quickly and on time with excellent results. The areas affected were clean and tidy when the work was completed. We had a slight problem with a unit but it was dealt with as soon as it was reported. I have no hesitation in recommending this company and will definitely contact them again for any further electrical problems.
