"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

"Joe and his team of electricians led by Paul were amazing to work with! Very professional, on-time, and fair pricing estimates for electrical work I needed in my condo, including moving the position of a ceiling light and setting up two new sconces, both of which required patching up the drywall afterwards and they made it look seamless. Joe really values quality work and made sure to check in throughout the job and afterwards to make sure I was satisfied, answering any questions I had. They offer a ton of handyman services and I will be booking them for future tv mounting needs as well."
