Too many people will make the mistake of assuming that as long as a problem seems small and it doesn't seem to be hurting anything that they can just brush it off and forget about it. However, when it comes to electrical problems, there is no such thing as a small problem. You will want to make sure that you are calling an electrician for issues such as:
There's A Spark
This isn't a spark between you and your significant other. This spark is of the dangerous kind and it can sometimes be seen when you plug something into an outlet. It might be a tiny spark that you barely notice, or it could be big enough to zap you a little. Either way, it is a sign that the outlet is going bad and you should discontinue its use until a licensed electrician replaces it.
There's A Lot Of Bad Bulbs
While it is normal to occasionally replace light bulbs in the house, it is not something that you should have to do often, especially if there is one light fixture that is burning out more bulbs than any other fixture in the home. This is a sign that there is something going wrong with either the electrical wiring or the light fixture itself. You will want to have an electrician come to your home to double-check the condition of the wiring and determine if you need a new light fixture.
The Light Switch Jiggles
If you discover that one of the light switches in your house jiggles a little bit whenever you go to turn it on or off, you might want to give an electrician a call. Most likely, you are just going to need a new switch installed, but you are going to want to have that done as soon as possible. If you wait too long, you could find that you are unable to get the switch to work anymore because of a complete disconnection.
The Plastic Is Warming Up
You want to make sure that you are aware of the temperature of the light switches and outlets when you go to use them. This will help you discover any problems soon after they begin. If you feel that the plastic cover, the switch, or the outlet itself feels warm to the touch, you will want to immediately stop using it. Call an electrician because there could be a short in the wiring.
Make sure that you are locating a reputable electrician in your area. This way, should the time come when you need to call for assistance, you will already know who to contact.
