"The team at Avant is next level. From planning, to prep and through final inspections, Avant’s skilled approach allows the home-owner to get from ideation to ”finished” without any pressure to do more than our budget allowed. We upgraded our panel; moved the PG&E drop so the wifi meter was no longer next to our master suite; installed a new EV fast-charger; installed a new home security system; upgraded indoor and installed new automated outdoor lighting AND re-wired all our 220a appliances. I’d recommend Avant for any home-owner seeking high value excellent workmanship!"

"JP Services installed a Moen Flo water leak detector. The original pipe was a little short, so he extended it to install the device. The job was done well, but he had to fix a small leak he caused and left some residue from his blowtorch. Overall very worth the price."
