"Amazing, very professional, on-time, clean work,"

"Great job, we are pleased!"

"I rarely take the time to write reviews. But I must say, August Costanzo, his son who works with him, and their secretary Lisa have been an absolute pleasure to deal with. I received prompt replies after normal business hours, and August even sent me an unprompted e-mail on the 4th of July asking me details of the EV charger I needed installed. I had a small issue with paperwork on the install day, and not only did Lisa follow up on the paperwork, it was all ready and the job was done the next business day, with absolutely perfect work and a very clean install - and I take my electronic installs seriously. August gave me the most reasonable estimate out of 4 estimates, beat the next lowest estimate by 35%, and did fantastic work, all while taking care of the permits. Lisa, his secretary, will bend over backwards to help you, also responding to calls after hours. I can NOT recommend Costanzo Electrical enough. I wish I could give TEN stars."
