Thorough, professional, and responsible.
My experience with Benjamin Franklin Plumbing was a unique one. They were repairing my sewer line, and they used a new trenchless method. Because there was water under my house that we were unaware of, the method failed. They ended up having to dig up the whole yard and basically doing twice the amount of work that was needed originally.
They never once came back to ask me for more money; they just ate the price difference. They were as professional as I expected. Chris was very apologetic and cordial. I told Chris that because of that experience I would begin to recommend them. It could have been a huge debacle, and it was for them, but it wasn't one for me at all.
I am very happy with Benjamin Franklin Plumbing and the work done. I hired them again after that experience. It could have been thousands of dollars in repairs, but they just ate it.
