One of the most important things that must be considered when hiring an electrician is that you will have peace of mind knowing that the work performed will be professional and you can feel safe and secure knowing the job is well done.
The photos below are examples of very poor workmanship that I have run across from workers that claimed to be electricians. As you can see, accepting the low bid may not always be the best idea.
I see this type of work most often with companies that one or two persons do everything to save money and not subcontract the skilled work to a licensed, professional electrician. They are commonly called "Jack of all trades, master of none". It would be far too overwhelming and virtually impossible for one person to be a licensed and highly skilled plumber, electrician, heating cooling, carpenter, sheet rocker, cement worker and painter. If your contractor can't provide proof that they are licensed with a certificate of competency in every trade that they will be providing service to you in, then you might want to reconsider signing a contract with them.
One other thing to consider is that most cities have 2 types of licenses: skilled trade license and occupational license. A skilled license means that you have been trained and are knowledgeable in your field of trade. You are required to take a lengthy and costly test to prove you have the skills necessary to work in the trade. An occupational license is just a license required by certain cities for the privilege of working in their city. Many cities also require licensed trades people to take CEU classes each year.
Work done by people that claimed to be electricians
All electrical connections are required to be enclosed in junction boxes, use proper cable bushings and wire termination methods.
This was hidden behind the sheet rock where a box previously had been installed.These workers simply removed the box, spliced the wires together and then plastered over the hole. They made very poor connections causing the wires to come undone and that caused the circuit to fail. The concerned homeowner called us out to locate and repair the problem.
All electrical connections must be accessible and in approved junction boxes.
These 3 images show that the installers didn’t understand the electrical codes or chose to ignore them to cut costs at the risk of the homeowners safety.
If a contractor trys to convince you that he can save you money by doing all the work himself and not sub contract to the licensed trades be sure you tell them you want a permit and inspection done for all the work.
