"Great job wiring up a hot tub. Very thorough. When it turned out that our existing GFCI was bad, Jared was willing to wait while I hustled out to buy a replacement, and then took the time to get it installed in the undamaged side of the breaker box. He even helped get the hot tub primed (and it was stubborn!). I highly recommend him."

"Biagiarelli designed, installed a complete network with smart home automation. I asked Ben to use Homeseer and he did a great job. He also programmed Smart Pool Hayward. This was a very complex project which also included 200+ speakers, 32 zones of sonos, complete wife install, new alarm, under cabinet lighting, outdoor landscaping lighting and so much more. I highly recommend Biagiarelli Electric, especially if you need a technologically inclined electrician. He is friendly, knowledgable and reliable for installations and support :-)"
