greenenergy“It is unusual and reassuring to be able to have people doing work in your home, in whom you not only have confidence, but also trust implicitly. That has for many years been my experience with John O’Sullivan and O’Sullivan Electric.
The most important aspect of a company doing home repair and maintenance are attention to detail and follow through. That has always been a hallmark of O’Sullivan Electric; they are a proven commodity.”
