Railto Electrical Company
An electrician should be licensed and carry valid insurance. Verify that both are active and in good standing before starting a job. Damage done can be severe with improper wiring so this is very important. If an electrician can not provide you with both, do not hire them. There is too much at stake. Get copies of their license and insurance certificate.
Ask the electrician about their experience level. A Railto electrical company that has been in business for a long time will likely be a better choice than one that is just starting out. New businesses may offer price reductions to help them establish a client list and references. If opting for a new business, check that the electrician who is working on the job has significant experience with the type of work required. Request references and check them. Electricians who have happy customers will do a good job for you.
Choose the electrician who has the best combination of price and experience, and with whom you felt most comfortable. Get the project specifications in writing so you have a detailed accounting of the job, the costs, and time for completion. This will help protect you if anything goes wrong.
