We all know that San Francisco is an amazing and unique place to live. Like the city itself, San Francisco homes are also unique. Many San Francisco homes predate electricity. Others were built before it was common to ground electrical systems. Even brand new construction in San Francisco can be different than other cities due to the close proximity of homes. At REF Corp, we are experts at working in the unique homes found in San Francisco. We work in them daily. Whether its troubleshooting a vintage electrical system or figuring out how to install new lighting without removing your original tile, our technicians have the experience to get the job done.
