We are new customers of Dave and the folks at Nor-Cal Maintenance. They just completed an installation of gutter guards. They also power washed the house and exterior window cleaning. The latter two were done beautifully with minimal fuss. This is our first experience with gutter guards, so we can't speak to…

The men were respectful and professional. It didn't matter that it was raining at the time, they still did a great job with a great clean up. They know what they are doing. Would use again. Think about tipping if you like the job.

Nor-Cal Maintenance did an amazing job of cleaning gutters and getting all the algae/moss off the roof, they put on gutter covers and re-screened our screens. I highly recommend them.
