They will rip you off and have no morals. I had a gas leak last year in the middle of winter and needed to have my main gas line replaced. All of the other plumbing companies that I would usually use were booked several weeks out. There was a reason that Jayhawk Plumbing was available. They attempted to screw me over at every possible opportunity. They changed their rate in the middle of their job, they consistently had 2-4 plumbers onsite in a job that required no more than 1 or 2 plumbers, and it took them 3 days to replace 3 pipes. The line that they needed to replace was damaged due to the pipe making direct contact with the brick on the exterior of our home. Instead of putting a protective surface around the new pipe to prevent future leaks, these experts installed the pipe directly against the brick. This of course failed inspection by the gas company and required them to do their work again, thus charging me double. This is absolutely the worst company I've ever worked with and would not recommend them to my worst enemy.
