Reviews from customers on Angi.
Sidney Cox has always done a good job on a variety of jobs. Highly recommend him.
Randy and his helper came out and did the repair quickly and professionally. I was so impressed I asked him to have a look at two lavatory drains that hadn't worked for years.
They came out the day after we called, used a camera to find the leak, cleaned up after themselves, and were very friendly. I would call them again for any plumbing needs.
I've used Sidney Cox multiple times for different rental properties. His employees have always done quality work. Sidney Cox is my go-to plumber.
