The job went exceptionally well. Allan and Dave were here all day and did an excellent job keeping us informed of their activity as they proceeded. Gary Epstein did an exceptional job in coming to estimate the job, scheduling the job (including coordination with the Fairfax County Electrical Inspectors and Dominion Virginia Power), and checking on our job satisfaction. Gary quickly responded to each of our questions. We definitely recommend Certified Electrical Contractors for electrical work.

Certified Electrical sent an e-mail to confirm the appointment, and requested a picture of my electrical panel. From the picture, they were able to determine exactly the parts I needed.

From my perspective, a perfect service call. I will definitely be calling them again for additional work.

On second inspection, the job passed. To be clear, I don't think that there was a problem with work quality but more that there was n... read more

It went well; I was asked if I wanted to follow the inspector, but I declined to do so. I received a postcard and a phone call reminding me of my appointment. Overall, it went well and if there's a problem in the future, I will definitely call CET.

CET did a great job replacing a pendant lamp in our two story foyer/entryway. They arrived on time and did a great job. We would definitely use them again.
