I can't recommend Sa enough. I was power-washing my deck this spring for an hour. When I went back inside, I discovered a Biblical flood had occurred from a burst pipe, without me knowing. My basement was a disaster. I called 4 plumbers on Yelp, on a Saturday, only one answering and unable to come until the next morning. Then I found Sa. 90 minutes later (and because he needed to eat lunch first), he showed up!!!!
He spoke good English and was professional in appearance, demeanor, and work. He gave an estimate and explained to me what appeared to happen, and what he'd do. Then he did it all quickly and well. He also explained several things about our pipe work (some we didn't know). After repairing the pipe, he also made good suggestions for better insulating the pipe from future freeze issues.
He gave up a round of golf to come help us on his day off, despite the weather being beautiful, and as a fellow golfer, I know how important that is ;)
This whole thing was a big deal to us because the insurance company told us that the water-damage-repair guys wouldn't come out until the plumbing was fixed, so getting someone here fast was crucial. I learned the pipe burst at 1:30, Sa was here by 3:15! From VA! He was done by 4:30. Thanks to him, the water guys were here by 6:30 pm. The next best plumber wasn't available until 7am the next day.
