We recently had Knight Plumbing at our house working on a project (installing new hose bibs, replacing existing ones for frost free bibs, installing back flow preventers into the sewer line, and replacing a "home job" sump). The work done by Jason and Tyler was excellent. Not only did they have to deal with two young kids, a nosy dog, and general chaos around our house, the work completed was well done. Jason is super knowledgeable and took the time to explain the entire scope of the project to me (they had to deal with the previous owners "jimmy rig" job, which was a nightmare).
On a side note, as they were leaving my house one day, they were organizing one last stop at an elderly ladies home, as they had a few extra minutes to spare. It's very rare to see employees go the extra mile, especially when most people would have wrapped their day up with only 25 minutes left in the day. These guys are seriously awesome, and its obvious to me now why Knight is on the top of HomeStars recommends list.
