Keeping your electrical outlets and switches in good working order is a very important part of keeping your home safe. When outlets start to become exposed or the wires within them become frayed, they can become a very dangerous liability in your home. It is imperative that you do not use an unlicensed contractor for work like this. Installing electrical outlets in your home requires someone to connect new wiring to your home's grid. This is a very dangerous process that should only be handled by a qualified contractor who's licensed to operate in your state. If you use an unlicensed contractor, then you have no idea how much that person does or does not know about safe wiring. The extreme level of danger this presents is simply not worth the savings you may find by hiring an unlicensed contractor. You should also remember to find a contractor who's knowledgeable about different types of lighting. For example, imagine that you want to have a dimmer switch installed in your living room. Since most compact fluorescent bulbs do not dim, a contractor installing dimmers for a CFL outlet will only be wasting your time and money.
