A should have been simple to fix leaky bathroom faucet turned into a nightmare when the pipe leading from the wall to the shut-off _broke_ off resulting in an emergency fix needed to get water back in my house.
After calling Mr. Plumber and explaining the problem, Andrew and Alex showed up at the appointed time (roughly an hour after I'd called) and immediately upon stepping through the door put on shoe covers without me asking - a small but important gesture that showed respect for my home.
They proceeded to examine the problem, provided a more than reasonable quote given the circumstance and urgency, and had the shut-off valve fully repaired in about 45 minutes.
On top of that they graciously demonstrated how I could fix the dripping faucet myself (which was still an issue, but hardly a major concern at this point) where they could have easily attempted to bill me extra for that.
I am very happy with with their service and would definitely use them again as well as recommend them to others.
