Excellent service. They don't mess around. We had a leaking kitchen sink, a few months ago, and it was fixed in 20 minutes. With brazing, joint replacement, and soldering I was very happy with their service.
We have a leaky sink. They came today, and 15 minutes later they left due to lack of parts here in town. They're getting them in Battle Creek, and will reschedule. They tell you the problem in easy to understand terms, and are always courteous.
Update: They're finishing the work now and are in fact replacing a part on the hot water side of the sink so they don't have to return in a month or two.
