Our Happy Clients Say:

“We had no idea our old home still had knob-and-tube wiring until our insurance company flagged it. The team was quick to respond, walked us through the process, and completed the full replacement in just a few days. They were clean, did a good job, and made us feel safe the whole time. Now everything’s up to code, and we even got a better rate on our home insurance.”

“After buying a 1920s home, we knew we’d eventually have to replace the old knob-and-tube wiring. When we called to get a price, the team was very helpful and honest, which impressed us. Their job was to make sure everything was safe and up to code and to explain each step of the upgrade. With little disruption, the work was completed quickly. Easily one of the best contractor experiences we’ve had in San Francisco.”

“Our real estate agent recommended upgrading the electrical system before listing our property, since it still had partial knob-and-tube wiring. The electricians did a fantastic job — clean work, detailed documentation, and everything passed inspection with zero issues. Thanks to them, we closed the sale without delays and with added value. Highly recommend to anyone dealing with outdated wiring in older homes.”
