Hi Neighbors, I recently looked for an electrician recommendation for our driveway light repairs. I used Cavanagh Electric who came highly recommended from this forum. I have to say what a great Electrician, Bill was able to fix our lights, he was great, so nice and efficient. I will definitely use him again. Thank you so much for the great recommendation

Everything looks great. I'll be calling Cavanagh Electric again! Thank you Bill.

It is not often that a workman impresses you beyond your wildest expectations. I had many workmen in my day.
