Reviews
What your neighbors say.
Every word below is from a real Google review. Names are the reviewers' own. Read the rest, or add yours.
- EV charger & new circuits
“Alex took the time to debug my panels and found I had plenty of amperage for my projects, when other electricians were trying to upsell me on more amps than I needed. He was also the only one ensuring we get a permit and do everything the right way.”
- Same-day service
“TopTech Electrical was incredible. Alex was very responsive and came out same day.”
