My wife had the most interaction with Benjamin Franklin Plumbing Bay Area Concord, but because they did such a top-notch job, I was happy to do the review. This is the first time we have used them for a long time. We called about a stopped-up drain line and they responded that day. The gentleman that came out went above and beyond in order to fix our problem. He was very happy to solve the problem and it was a bit of a mystery. He crawled under our house, which has a very small crawl space, without any complaint. He had a great attitude and was very polite. I highly recommend them. If we have a problem in the future, I will be calling them and requesting the gentleman who solved our problem this time.
